Abstract

Aim

This study aimed to compare the effectiveness of interdisciplinary work between dentistry and physiotherapy as well as to determine the temporomandibular disorders (TMD) patients’ treatment plan.

Materials and methods

The sample consisted of 300 patient records from the ATM service (Faculty of Dentistry, Federal University of Juiz de Fora) file. Three factors were analyzed: (1) Therapy, which were transcribed physical therapy modalities used; 2) If there were any guidelines or procedures for home exercises without the professionals presence; 3) the temporomandibular joint (TMJ) palpation pain rates, transferred to a pain level measurements table according to visual analog scale (VAS). The Chi-square test was applied for statistical analysis with a significance level p ≤ 0.05.

Results

All physiotherapy modalities used separately or mixed contributed to TMJ pain relief. Guidelines for physical therapy at home proved to be very useful to pain decreasing.

Conclusion

It was concluded that the effectiveness of an interdisciplinary work in dentistry and physiotherapy treatments for TMD has been properly verified. It is essential to have an interdisciplinary treatment plan, where the physical therapy helps the pain relief and dentistry treats the disorders related to the stomatognathic system.

Clinical significance

The interdisciplinary work between dentistry and physiotherapy is more effective in TMD treatment.

[Year:2012] [Month:September-October] [Volume:13] [Number:5] [Pages:6] [Pages No:584 - 589]

PDF  |  DOI: 10.5005/jp-journals-10024-1191  |  Open Access |  How to cite  | 

Abstract

Aim

The aim of this in vitro study was to evaluate the surface roughness and hardness of both unbleached and bleached (opalescence; 10% carbamide peroxide) human enamel brushed with water (without dentifrice), fluoride abrasive dentifrice (Colgate Total) and whitening dentifrice (Natural White).

Materials and methods

Human enamel samples were obtained from third molars and randomly divided into five groups (n = 8): G1—Control (brushed with water without dentifrice), G2—Colgate Total (fluoride abrasive dentifrice), G3—Natural White (whitening dentifrice), G4—Opalescence (10% carbamide peroxide) and then brushed with Colgate Total, G5— Opalescence (10% carbamide peroxide) and then brushed with Natural White. Bleaching regimen was applied according to manufacturers’ instructions. The brushing process was performed with a modified Nyffenegger's brushing machine. Surface roughness was analyzed with a profilometer. Microhardness testing was performed with a Brinell hardness tester.

Results

Results were statistically analyzed by Kruskal-Wallis, one-way ANOVA analysis and Mann-Whitney U, Wilcoxon matched-pairs signed-ranks tests. There were significant differences in surface roughness values for all groups, which showed an increase in roughness (p < 0.05). When the bleaching treatment combined with brushing with whitening dentifrice was performed (G5), there was a significant decrease in hardness values (p < 0.05). The other groups (G1, G2, G3, G4) showed no significant hardness differences (p > 0.05).

Conclusion

It was concluded that toothbrushing procedures increased the enamel surface roughness, and that bleaching regimen performed with cleaning treatment, through brushing with whitening dentifrice decreased hardness values.

Clinical significance

When applied together, bleaching and cleaning treatments may alter the enamel surface roughness and hardness values.

Abstract

Aim

Definitions of the ala-tragus line (ATL) cause confusion, because the exact points of reference for this line do not agree. This study determined the relationship between the prosthetic occlusal plane (OP) corresponding to the lateral borders of the tongue and ATL which was established by using the inferior border of the ala of the nose and (1) the superior border of the tragus (ATL 1), (2) the tip (ATL 2) and (3) the inferior border of the tragus (ATL 3).

Materials and methods

Neutral zone moldings using phonation and autopolymerizing acrylic resin were recorded and leveled with the lateral borders of the tongue. Lateral cephalometric radiographs were taken of each subject by a standard method. Tracings were obtained on acetate paper to show the prosthetic OP and the three ATLs. The relationship between the prosthetic OP and each of ATL was measured for each subject. Mean and standard deviation values were then calculated for the relationship. Statistical analysis was performed using repeated measure analysis of variance followed by Bonferroni pairwise comparisons and Student's t-test (α = 0.05).

Results

Significant difference was found between the three mean angles (p = 0.001). There was no significant difference between the mean angle (5.00° ± 4.38) formed by OP and ATL 2, and the mean angle (4.90° ± 3.50) formed by OP and ATL 3 (p = 1.00) which revealed the smallest.

Conclusion

The findings of this study indicated that ATLs, extending from the inferior border of the ala of the nose to (1) the tip of the tragus of the ear, and (2) the inferior border of the tragus presented the closest relationship to the prosthetic OP corresponding to the lateral borders of the tongue.

Clinical significance

When the ATL is used for orientation of the OP in denture construction, it would seem preferable to define it as running from the inferior border of the ala of the nose to the tip or to the inferior border of the tragus of the ear.

Abstract

Aim

The aim of the present study was to evaluate the effect of three methods of composite fiber placement along with siloranebased composite resin on cuspal deflection and fracture strength of root-filled maxillary premolars.

Materials and methods

Mesio-occluso-distal cavities were prepared in 60 extracted premolars subsequent to endodontic treatment. The remaining thickness of buccal and lingual walls at height of contour was 2.5 ± 0.2 mm and the gingival cavosurface margin was 1.5 mm coronal to cementoenamel junction. Subsequent to measurement of primary intercuspal distances, the teeth were randomly divided into four groups. In group 1, the cavities were only filled with Filtek Silorane composite resin. In the other three groups, preimpregnated glass fibers were placed at gingival, middle and occlusal thirds respectively, and the cavities were restored similar to the group 1. Cuspal deflection was recorded in micrometer using a stereomicroscope. Fracture strength of the samples was measured in Newton subsequent to thermocycling. Data was analyzed using Kruskal-Wallis, Mann-Whitney U, one-way ANOVA and post-hoc Tukey tests at a significance level of p < 0.05.

Results

The highest cuspal deflection was recorded in the group 1, and the difference between group 1 and other groups was significant (p < 0.001). Fracture resistance in group 4 was significantly higher than that in other groups (p < 0.001).

Conclusion

In restoring root-filled premolars with siloranebased composite resins, cuspal deflection decreased with the use of preimpregnated glass fibers.

Clinical significance

Using preimpregnated glass fibers along with silorane-based composite resin may lead to better results in cuspal deflection and fracture resistance of endodonticallytreated maxillary premolars.

Abstract

Aim

The main objective of any orthodontic treatment is to achieve well-established stable occlusal relationship with a definite positive change in facial profile. The purpose of this study was to determine, if such a goal is achievable for patients who could be classified as borderline surgical cases without the invasive use of the actual surgery or, with the use of the recently developed and rapidly spreading fixed functional appliance system (Forsus) and a comparison of the esthetic treatment outcome with the two systems.

Materials and methods

Twelve postadolescent borderline skeletal class II patients with a deficient mandible. All the patients used in the study were treated by a preadjusted edgewise appliance for presurgical decompensation with or without extractions and for postsurgical finishing and detailing. Out of the 12 patients six were treated with bilateral saggital split osteotomy (BSSO) and six were treated with fixed functional appliance (Forsus).

Results

The results suggested that although surgical patients had a better mandibular advancement, profile reduction, and marked improvements in soft tissue structures, the patients who had undergone fixed functional therapy also had comparable improvement in the above aspects. In the maxilla there was no change in cases treated with surgery but in case of Forsus some retraction of anterior dental segment was evident.

Conclusion

In surgical group, class II malocclusion correction was more skeletal than dental, whereas in functional group class II malocclusion correction was more dental than skeletal.

Clinical significance

Looking at the common surgical risks, cost-effective and postsurgical problems and patients with borderline class II malocclusion, fixed functional therapy is a valuable adjunct in the management of class II malocclusion.

Abstract

Aim

Evaluating effects of a denture cleanser on weight, surface roughness and tensile bond strength on two resilient lining materials.

Materials and methods

Specimens of heat cure acrylic resin were prepared to verify weight change, surface roughness and tensile bond strength. Specimens were divided into four groups: Relined with resilient liner Visco-gel, soft liner immersed in Clinsodent denture cleanser and water and evaluated immediately, 24 hours, 7 and 15 days. Weight changes, roughness and tensile bond strength were determined and data submitted to statistical analysis.

Results

Visco-gel specimens immersed in water (group 1) have shown significant increased surface roughness than those immersed in Clinsodent (group 3) during 24 hours, 7 and 15 days. The soft liner specimens immersed in water (group 2) have shown increased surface roughness than those immersed in Clinsodent (group 4) during 24 hours and 7 days. Visco-gel specimens immersed in water have shown significant increased tensile bond strength during 7 and 15 days than those immersed in Clinsodent. The soft liner specimens immersed in water have shown increased tensile bond strength than those immersed in Clinsodent during immediately, 24 hours and 7 days.

Conclusion

Within limitations of this study, specimens immersed in Clinsodent demonstrated increased weight changes compared with water. Specimens immersed in water demonstrated lesser surface roughness and tensile bond strength compared with specimens immersed in Clinsodent.

Clinical significance

Resilient denture liners and denture cleansers are most commonly used materials in prosthodontics. Caution should be taken while selecting the materials which cause the detrimental changes on properties of the materials.

Nature of Occlusion during Eccentric Mandibular Movements in Young Adults

[Year:2012] [Month:September-October] [Volume:13] [Number:5] [Pages:6] [Pages No:612 - 617]

PDF  |  DOI: 10.5005/jp-journals-10024-1196  |  Open Access |  How to cite  | 

Abstract

Aim

The aim of this study was to find out the nature of occlusion and tooth contact during various eccentric mandibular movements in young adults with class I occlusion.

Materials and methods

The sample consisted of 100 young adults with class I occlusion with full complement of teeth.

Anterior disclusion in centric occlusion was demonstrated using a shim stock interposed between the upper and lower anteriors. Disclusion of posteriors was ascertained during 1.5 mm straight protusion and in edge-to-edge protrusion, visually as well as using a silk floss method. Posterior disclusion was also verified during lateroprotrusion and crossover. Besides these occlusal wear of teeth also were observed.

Results

The results of this study showed that the anterior disclusion is seen only in one-fourth of the subjects compared to almost three-fourth showing posterior disclusion. Mutually protected occlusion was also seen only in one-fourth of the subjects. Canine protective mechanism is seen in a relatively large number of subjects, but it was not overwhelmingly predominant. No correlation could be established between cuspid wear and the type of occlusion. A relatively high percentage of subjects showed wear on posterior teeth when there was no posterior disclusion.

Conclusion

From the above study it is seen that posterior disclusion is acknowledged as a common factor except when a bilateral balance is present. Since bilateral balance is harmful, the ideal occlusal relationship in eccentric movements is in favor of posterior disclusion. Posterior disclusion is easily obtainable when restorations are planned.

Clinical significance

From the findings and results it has been possible to make some contributions on the nature of tooth contacts and disclusion during various eccentric movements and compare it with the requirements of ideal occlusion.

Evaluation of Elongated Styloid Process on Digital Panoramic Radiographs

[Year:2012] [Month:September-October] [Volume:13] [Number:5] [Pages:5] [Pages No:618 - 622]

PDF  |  DOI: 10.5005/jp-journals-10024-1197  |  Open Access |  How to cite  | 

Abstract

Background and objective

The elongated styloid process may produce characteristic head and neck pain syndromes, commonly known as Eagle's syndrome. An awareness of this syndrome is important to all health practitioners involved in the diagnosis and treatment of neck and head pain. It has been estimated that 2 to 28% of the general adult population has radiographic appearance of elongated styloid process.

The objective of the study was to assess the elongation of styloid process on digital panoramic radiographs and to evaluate the prevalence of elongation according to age, sex and types.

Results

Elongated styloid process was seen in 107 subjects out of 300 patients who were aged between 10 and 70 years old. Our study revealed that as age increased elongation of styloid process increased with female predominance. Type 1 elongation was most common than the other types of elongation. We also found that left styloids were elongated than the right with bilateral elongation.

Conclusion

Panoramic radiographs can show a correct picture of elongated styloid process which can confirm the diagnosis and can thus help avoid misinterpretation of the symptoms as tonsillar pain or pain of dental, pharyngeal or muscular origin and hence panoramic radiography is economical and the best imaging modality to view the elongation of styloid process.

Abstract

Aim

The present study was undertaken to study the role of nitric oxide in human saliva and its diagnostic/prognostic role in recurrent aphthous ulcers (RAU) and oral lichen planus (OLP).

Materials and methods

The study was carried out at outpatient department of Govt Dental College and Hospital, Aurangabad. Twenty cases with RAU, 15 with OLP and 30 healthy individuals were included in the study. The clinically diagnosed known cases of RAU and OLP were included after taking the detail case history and subjected to blood analysis for hemogram and biochemically salivary nitric oxide was estimated.

Results

The salivary nitric oxide levels were found to be increased significantly in RAU and OLP group, when compared with controls. Further, significantly increased levels have been observed in OLP group, when compared with RAU group (p < 0.001). The salivary nitric oxide levels were found to be increased significantly in minor RAU than major RAU and increased in erosive type of OLP than nonerosive type of OLP.

Conclusion

Thus, salivary nitric oxide can be treated as a diagnostic tool for the differential diagnosis of RAU and OLP.

Clinical significance

Nitric oxide plays an important role in modifying physiopathological processes of oral mucosal membrane so has diagnostic as well as prognostic value.

Abstract

Introduction

Occlusion and occlusal plane is the primary criteria in fabrication of posterior restorations. The simplest method of establishment of occlusal plane is through the use of Broadrick occlusal plane analyzer.

Aims

This study aims to know the reliability of Broadrick flag in determination of curve of Spee with different proposed radii in different skeletal relation in Indian population.

Materials and methods

Male and female dentulous subjects were selected randomly. Maxillary and mandibular full arch impressions were made; casts were prepared and mounted in semiadjustable articulator using face bow transfer. Broadrick occlusal plane analyzer was mounted on upper member of articulator. Analysis was done using the proposed radii of curvature. The same procedure was repeated by taking different radii with variations of ¼ inch, difference was measured by metal caliper, tabulated and subjected to statistical analysis.

Comparison of Microleakage of Composite Restorations using Fifth and Sixth Generation Dentin Bonding Agent: An in vivo Study

[Year:2012] [Month:September-October] [Volume:13] [Number:5] [Pages:5] [Pages No:632 - 636]

Abstract

Introduction

The success of bonded restorations depends on effective bonding between restorative materials and tooth structure, and it prevents microleakage. New dentin bonding systems have been introduced which promotes this concept. The aim of this study was to compare the amount of microleakage between ‘single bond’ vs ‘Prompt L-Pop’ during different time periods.

Materials and methods

In this clinical trial study, 60 nonretentive class five cavities were prepared on buccal surfaces of human premolars which were scheduled to be removed for orthodontic purposes. The cavities were restored using two different bonding agents; fifth generation (Single Bond) and sixth generation (Prompt L-Pop) and then filled with resin composite (Filtek Z-250). The samples in both groups were extracted after placing the restoration in three periods of time: Immediately, 1 week and 6 months postplacement. Specimens were sealed with two layers of nail varnish except for 1 mm around restoration and immersed in a silver nitrate solution for 24 hours. The teeth were then sectioned longitudinally and the degree of microleakage was determined by stereomicroscope based on standard usual criteria.

Results

Single bond showed more leakage at dentin margin than enamel margin in all three extraction periods and differences were significant among three groups (p < 0.05). In samples which were restored with Prompt L-Pop only in groups of 6 months there were significant differences between enamel and dentin margins. At enamel margin there were no significant differences between microleakage of groups according to the passage of time (p > 0.05).

Conclusion

The results of this study using two different bonding systems, indicate that adhesion to enamel was more valuable than dentin and perhaps systems that include self-etching primers are less sensitive to remaining moisture on dentin and they are less affected during different time periods.

PDF  |  DOI: 10.5005/jp-journals-10024-1201  |  Open Access |  How to cite  | 

Abstract

Aim

The aim of this study was to evaluate and compare the shear bond strength of hydrophilic materials like Transbond MIP with Assure-fluoride releasing light cure sealant paste system (Reliance orthodontic product), Enhance Lc-adhesion booster (Reliance Orthodontics) Prime and Bond NT–one step adhesive with nanotechnology (Dentsply Product India) with Transbond XT as the control group.

Materials and methods

The study was conducted on 180 extracted human premolar teeth which were divided into five main groups. Each group contained 36 teeth, which were further subdivided into three subgroups containing 12 teeth. The teeth were bonded in three different surface environments namely dry, contaminated with artificial saliva and reprimed after contamination with artificial salvia. The brackets were bonded and cured. The shear bond strength was tested using Instron universal testing machine (4501).

Results

The results were subjected to statistical analysis like 3 factorial ANOVA and compared to post-hoc using the Student Newman levels test. The residual resin on the tooth surface after debonding was evaluated with adhesive remnant index.

Clinical significance

The results revealed that in situations in which moisture contamination is critical there is distinct advantage in using hydrophilic primers.

Abstract

Aim

The aim of the present study was to evaluate these two high intensity light curing units regarding microleakage beneath metal and ceramic brackets.

Materials and methods

A total of 60 freshly extracted human premolar teeth were randomly divided into four groups of 15 samples; group I: Metal bracket + LED cured, group II: Ceramic bracket + LED cured, group III: Metal bracket + plasma arc cured, group IV: Ceramic bracket + plasma arc cured.

After photopolymerization, the teeth were immersed in water and thermocycled (500 cycles between 5 and 55). Specimens were further sealed with nail varnish and stained with 5% basic fuchsin for 24 hours. All of the teeth were sectioned with two parallel longitudinal occlusogingival cuts and examined under a stereomicroscope. The microleakage was measured with a digital caliper and scored from 0 to 3 for marginal microleakage at the bracket-adhesive and adhesive-enamel interfaces from both the occlusal and gingival margins.

Results

Microleakage was detected in all groups. The plasma arc cured group showed less microleakage than light emitting diode (LED) cured in all samples at the enamel-adhesive interface at the gingival margin (ceramic brackets, p = 0.009 and metal brackets, p = 0.005). The plasma arc cured samples showed less microleakage than LED cured in metal brackets at the adhesive-brackets interface at the occlusal margin (p = 0.033). While curing with an LED unit, ceramic brackets displayed significantly less microleakage than metal ones at the gingival margin of adhesive-enamel interface (p = 0.013).

The gingival margin in all groups exhibited higher microleakage compared with those observed in occlusal sides in all sample groups (p < 0.001).

Conclusion

1. LED units cause more microleakage than plasma arc units.

2. In all groups the microleakage at the gingival margin is greater than the occlusal margin.

Clinical significance

The microleakage formation permits the passage of bacteria and oral fluids initiating white spot lesions beneath the bracket base.

Abstract

Materials and methods

The sample consisted of 50 human premolar teeth collected and stored in formalin. Out of 50 samples, 38 were upper premolars and 12 were lower second premolars. The total sample divide into 10 each. Stainless steel contour bracket with bondable mesh measured about 3.42 mm in length and 3.31 mm in width. Each tooth sample was embedded in a cylindrical acrylic block of polymethyl methacrylate (PMMN). The buccal surfaces of all the samples were polished with fluoride-free pumice and rinsed thoroughly. Group 1 bonded with GC Fuji Ortho after getting etched with 37% phosphoric acid/60 seconds. Group 2 was contaminated with saliva. Group 3 was conditioned with Fuji dentin condition. Group 4 unetched, uncontaminated, and Group 5 was treated with rely bond composite resin after getting etched with 37% phosphoric acid. The shear bond strength was tested using Instron universal testing machine. The force at which bond failed was recorded on XY recorder as shear/peel bond strength of the material used for bonding. The reading obtained were statistically analyzed.

Result

Rely bond showed highest bond strength of 64.70 N (Newtons). The next highest value was that of Group 1. The lowest bond strength in the Group 4.

Conclusion

GC Fuji Ortho can be used as a bonding agent on etched enamel. Unetched, uncontaminated enamel surfaces were inadequate for bracket bonding.

Clinical significance

Potential benefits of glass ionomer cements can be utilized in orthodontic bonding.

Abstract

Aim

To evaluate the influence of salivary contamination during dentin bonding procedures on shear bond strength and to investigate the effect of contaminant-removing treatments on the recovery of bond strength for two dentin-bonding agents.

Materials and methods

Seventy-seven human maxillary and mandibular molars were randomly divided into two groups for total-etch adhesive (Single bond-3M ESPE, USA) and self-etch primer (UniFil Bond-GC, Tokyo, Japan) and subjected to contamination with saliva.

The data for each group were subjected to one-way analysis of variance (ANOVA) followed by the Student Newman-Keuls test to make comparisons among the groups (p < 0.05).

Results

Salivary contamination had less adverse effect on the shear bond strength of single bond total-etch adhesive when it was blot dried or washed. UniFil bond was tolerant of salivary contamination, except when contamination occurred after application of the primer.

Conclusion

In single bond adhesive, when the etched surface is contaminated by saliva, blotting the surface and applying the primer can recover the bond strength. Complete drying of the salivary contaminated surface should be avoided. In the UniFil bond groups, the repriming treatment (UF-V and UF-VI) resulted in the recovery of shear bond strength in the specimens contaminated after priming.

Clinical significance

The results of this study showed that total- etch adhesive (single bond) was not affected by salivary contamination on the etched surface when the bonding surface was kept moist. Self-etch adhesive (UniFil bond) also tolerated salivary contamination except when the contamination occurred after application of the primer.

Abstract

Background and aim

Monitoring is the global method of observation and data recording in relation to body organ and system function that afford constant information to ensure continuous evalutation of the patient's physical condition. Basic monitoring provides essential information for assessing the vital signs, both circulatory and respiratory, and fundamentally comprises the control of blood pressure (BP) and heart rate (HR) and rhythm. Pulse oxymetry is used to record HR and oxygen saturation. The objective of the study was to assess and compare hemodynamic changes by monitoring oxygen saturation level changes during periodontal surgical and nonsurgical therapy.

Materials and methods

A cross-sectional observational study was conducted in 30 chronic periodontitis patients. Patients were divided into two groups; Group A consisted of 15 patients undergoing surgical periodontal therapy, Group B consisted of 15 patients undergoing nonsurgical periodontal therapy. The hemodynamic changes were evaluated by monitoring HR and oxygen saturation level using pulse oxymeter (SaO2). HR and SaO2 were monitored continuously and registered pre-operatively, i.e. 10 minutes before the procedure, intra-operatively and postoperatively, i.e. 10 minutes after the procedure. One-way analysis of variance test (ANOVA) was performed for data analysis.

Results

Both the groups showed a slight fall in oxygen saturation levels intraoperatively, but within the normal range. More decrease in oxygen saturation levels was observed in nonsurgical periodontal therapy as compared to surgical periodontal therapy at intraoperative levels. The differences in the values were statistically significant. There was no statistical difference seen in the postoperative and preoperative values.

Conclusion

Most of the hemodynamic changes induced during the periodontal therapy were within normal limits, taking into consideration the anxiety and stress produced by the surgical intervention. The hemodynamic change was more in nonsurgical as compared to surgical periodontal therapy.

Abstract

Introduction

Candida albicans is the most commonly isolated fungi from the oral cavity. It is the most infective to various intracanal medicaments and is considered as invasive yeast. Sodium dichloroisocyanurate (NaDCC) which is used as a disinfectant and as a biocide in treating potable water has similar action to that of sodium hypochlorite against microbes. The aim of the present study is to compare the effectiveness of calcium hydroxide and NaDCC against Candida albicans.

Materials and methods

After obtaining the stock cultures of Candida, the isolates were divided into six groups which were exposed to different concentrations of NaDCC and calcium hydroxide Ca(OH)2. Group 1 consisted of the isolates which were subdivided into three groups, subjected to three different concentrations of NaDCC. Group 2 also consisted of three subgroups exposed to three different concentrations of Ca(OH)2. Group three consisted of three subgroups which were exposed to three different concentrations of combinations of both NaDCC and Ca(OH)2.

Results

The results of the present study show that calcium hydroxide was totally ineffective at all concentrations and NaDCC was effective and also the combination of both was shown to be effective.

Conclusion

NaDCC alone was effective at all concentrations and the combination with Ca(OH)2 was found to be less effective. Ca(OH)2 was totally ineffective.

Abstract

Background

The mortality and morbidity associated with oral squamous cell carcinoma (OSCC) can be greatly reduced if tumor markers which can detect OSCC at an early stage are available. The use of saliva as an alternative to blood could provide a substantial advantage in sampling convenience. Cancer antigen 125 (CA 125) is a tumor-associated antigen found to be increased in epithelial tumors like oral, breast and ovarian cancers.

Aim

To determine whether salivary CA 125 levels are increased significantly in OSCC patients than the control group.

Materials and methods

Sixty OSCC patients and 60 healthy controls were taken for the study. Saliva samples from both the groups were collected, centrifuged and supernatant fluid were subjected to ELISA for assessment of CA 125. The mean salivary CA 125 values of OSCC patients and control group were statistically analyzed using Mann-Whitney U-test.

Results

The mean salivary CA 125 concentration of OSCC group was 320.25 and that of control group was 33.14. Thus, CA 125 was found to be significantly increased in the saliva of OSCC patients than the control group (p < 0.001). Also, there was significant increase in the CA 125 levels as the stage of OSCC increased.

Conclusion

The convenience, reliability and noninvasive nature of salivary CA 125 testing makes it a feasible adjunctive diagnostic tool for detection of OSCC.

Abstract

Background

Low birth weight is a known problem worldwide and appears to be more pronounced in developing countries. In view of the implication of periodontal infection as one of the risk factors for low birth weight and considering the fact that in India only very few studies are conducted in this regard, the present study was conducted to determine whether maternal periodontal disease can act as a risk factor for low birth weight babies.

Materials and methods

The study group consisted of 62 primiparie mothers including 12 low birth weight cases who satisfied the inclusion/exclusion criteria. The age of the patients ranged from 18 to 37 years with a mean age of 23.27 years. Birth weight of the babies ranged from 1.64 to 3.75 kg and the mean weight was 2.67 Kg. Mean weight, height and body mass index (BMI) of the mothers were 53.47 Kg, 1.51 m, 23.48 respectively.

Results

Birth weight of the babies was regressed against age, BMI, plaque index (PI) and community periodontal index (CPI). Periodontitis was significantly associated (p < 0.0005) with a decrease of birth weight.

Conclusion

Periodontal disease was significantly related to preterm low birth weight.

Abstract

Background and objectives

In recent years, ultrasonics has gained prime importance and is considered a valuable tool in the dentist's armamentarium. Studies have confirmed that an aerosolized bacterial contamination is produced during the use of ultrasonic scalers.

Aim

To evaluate and compare the efficacy of preprocedural mouthrinsing using a bis-biguanide (chlorhexidine gluconate 0.2%) and high volume evacuator attachment alone and in combination in reducing the amount of viable aerosols produced during ultrasonic scaling procedure.

Materials and methods

A total 90 subjects were assigned to group I (who rinsed with 0.2% chlorhexidine gluconate prior to scaling), group II (high volume evacuator attachment was used during ultrasonic scaling) and group III (who rinsed with 0.2% chlorhexidine gluconate prior to scaling and in whom high volume evacuator attachment was used during ultrasonic scaling). Control group consisted of subject's whose mouth was scaled using a piezoelectric ultrasonic scaler without preprocedural rinsing or high volume suction.

Aerosol samples were collected using blood agar plates. The blood agar plates containing the aerosol sample were taken to the microbiology department as soon as the sampling was over and were subjected to aerobic culturing.

Results

The values obtained showed that all the three groups were effective in reducing the mean colony forming units (CFUs).

Conclusion

The results of this study showed that preprocedural rinse and high volume suction were effective when used alone as well as together in reducing the microbial load of the aerosols produced during ultrasonic scaling. There was a significant reduction in the number of CFUs in aerosol samples obtained.

Abstract

Purpose

The purpose of this study was to evaluate, in vitro, the contamination of toothbrushes and pacifiers by Streptococcus mutans, and the efficacy of microwave and chlorhexidine for their disinfection.

Materials and methods

Sixty pacifiers and 60 toothbrushes were contaminated with S. mutans and then divided into groups according to the disinfection protocol: Group 1—chlorhexidine solution; group 2—microwave sterilization; and group 3—sterile tap water. The devices were evaluated microbiologically after disinfection for the survival of S. mutans colonies and were examined. The results were analyzed statistically by ANOVA and Turkey test.

Results

The results of both types of evaluation showed a large number of S. mutans colonies after spraying with sterile tap water, and chlorhexidine spraying and microwaving were effective in eliminating colonies. Groups 1 and 2 were statistically similar to each other (p > 0.05) and differed significantly from group 3 (p < 0.05).

Conclusion

The 0.12% chlorhexidine solution spray and 7 minutes of microwave irradiation were almost equally effective for disinfection of pacifiers and toothbrushes.

Abstract

Background

In the recent past, the Russian Federation has seen a considerable increase in HIV caseload. A high level committee was formed to assess the status of dental infection control and safety (IC&S) in Russia. This article is one of the outcomes to assess the status of IC&S and is the research of a doctoral student (PhD) in public health.

Purpose

To assess needs in Dental Infection Control and Occupational Safety in the Moscow Metropolitan Region of the Russian Federation.

Materials and methods

A survey with variables assessing knowledge, attitude and practice of IC&S was administered to dentists practicing and or teaching in Moscow city and suburban areas on a convenience sample of dental practitioners.

Results

The total number of completed questionnaires were 303. Over 67% had up to three significant exposures to blood and potentially infectious materials (OPIM), but less than 30% got tested for HIV in the previous 3 months. Use of personal protective equipment was not based on anticipated exposure. Less than 10% had an understanding of Spaulding's classification with respect to sanitization, disinfection and sterilization. Only about 34% stated that there was a potential for infectious disease transmission through a percutaneous route and about 61% double gloved while treating patients with infectious diseases. Only about 61% disinfected impressions and most (83%) used alcohol for disinfection purposes. While 34% still used glass-bead sterilizers, about 13% did not sterilize handpieces between patients.

Conclusion

Results from this study indicated a disparity in the practice of infection control and safety procedures requiring formulation of nationwide dental safety standards. Further, there is a need in implementation of a standardized dental safety curriculum for dental schools and continuing dental education requirements in dental safety for practicing dentists in the Russian Federation.

Abstract

Aim

The aim of this article is to create awareness among the dental practitioners regarding the various accidents which can happen during a dental procedure and stress upon the preventive measures that can be taken to reduce the same.

Background

This article presents a case of aspiration of dental crowns by the patient and its retrieval by coughing and preventive measures which can be taken to avoid such circumstances.

Case description

A patient reporting to private dental practice accidentally aspirated the two-unit prosthesis (crowns) in the right lung during cementation. He was immediately taken to the hospital, where chest radiographs and computed tomographic (CT) scan were done in order to locate the actual position of the prosthesis. Bronchoscopy was planned to retrieve the crowns but the patient had a bout of cough and the crowns came out. A chest radiograph was taken to confirm the absence of crowns.

Clinical significance

Taking adequate precautions while performing any dental procedure in supine position can decrease the occurrence of such incidents. Rigid bronchoscopy is the advised method of retrieval in case the crowns are not coughed out.

PDF  |  DOI: 10.5005/jp-journals-10024-1217  |  Open Access |  How to cite  | 

Abstract

Background

Invasive cervical resorption (ICR) is not well understood by the professional, being misdiagnosed, leading to inappropriate treatment and unnecessary loss of tooth.

Introduction

ICR is defined as a localized process of resorption, which begins in the cervical area of the tooth, just below the epithelial junction and above the ridge crest in the area of the connective tissue insertion. Possible predisposing factors include external trauma, orthodontic movement, surgical procedures, periodontal disease and its treatments, endogenous bleaching, pressure generated by wind instruments and herpes virus infection. Different approaches have been suggested for the treatment of ICR, depending on the extent of the lesion and its location. However, in some cases due to the severity of the injury, there is no alternative but to tooth extraction, followed by restoration of the edentulous area.

Aim and objective

Discuss etiology, diagnosis and classification of the ICR, as well as different treatment options. Also is presented a case in which extraction was carried out, installation of the implant and ceramic crown, subsequent to a treatment approach that resulted in failure in the short-term period.

Conclusion

Early diagnosis of the ICR is critical to proper treatment and favorable prognosis. Interdisciplinary treatment should be instituted as soon as possible, avoiding the loss of the affected tooth. In advanced cases, treatment involving the installation of osseointegrated implants should be considered the first choice of treatment.

Clinical significance

Early diagnosis of the ICR is critical do prevent unnecessary tooth loss, once the prognosis for advanced cases is doubtful.
