Abstract

Aim

Social media is becoming the way for businesses, including health care professionals, to communicate with consumers. The study examines the use of social media by dental practices in the US.

Materials and methods

An electronic survey was sent to 22,682 dentists in the United States. The survey consisted of questions related to the use of social media in the dental practice. Data was analyzed using descriptive statistics and comparisons were made using a Fisher's exact test.

Results

A total of 573 responses were received. Social media was used in 52% of dental practices, the most common being Facebook. The use of social media was most commonly for marketing purposes (91%). Dentists younger than 45 years old were more likely to use social media in their practice than dentists 45 years or older (p < 0.001).

Conclusion

Dental practices actively use social media for marketing and communication. Many dentists are unsure how to measure the success of social media in their practice. Additional research is needed to measure the success of social media in a dental practice.

Clinical significance

Social media is a common way practices market and interact with their patients. There are some difficulties in determining what appropriate content for social media is and how to evaluate the success.

Abstract

Aim

The present study was conducted to assess the correlation of traumatic dental injuries and overjet among school going girls of age 11 to 17 years in Pune, India.

Materials and methods

A cross-sectional survey was carried out with 2045 school girls aged 11 to 17 years, attending public elementary schools in Pune, India. The traumatic dental injuries were assessed according to Ellis and Davey's criteria. Occlusion was recorded according to Angle's classification and overjet was measured using a WHO 621 probe. The data obtained was subjected to statistical analysis using Mann-Whitney test.

Results

There was a significant (Z −2.785) association between increase in overjet and occurrence of trauma. Children with increased overjet were 3.09 times more likely to have dental injuries.

Conclusion

It can be concluded from the present study that a significant correlation exists between amount of overjet and prevalence of traumatic injuries among children. The percentage of trauma prevalence increases with the increase of overjet.

Clinical significance

Traumatic dental injury is not a result of disease but a consequence of several factors that will accumulate throughout life if not properly treated. One of the most important factors significantly contributing to traumatic dental injuries is the anterior overjet. Hence, correction of increased anterior overjet may help in prevention of traumatic injuries.

Abstract

Aim

Herbal mouthwashes, such as persica (Salvadora persica, mint and yarrow extracts) and miswak extract have been shown to decrease gingival inflammation and plaque accumulation. The aim of this study was to compare the antimicrobial activities of persica and miswak extract with the conventional mouthwash chlorhexidine against Streptococcus salivarius, Streptococcus sanguis, Lactobacillus vulgaris and Candida albicans.

Materials and methods

In this in vitro study, blood-agar culture (Merk, Germany) was used to grow the streptococcus strains, saburd-dextrose culture (Merk, Germany) was used to grow C. albicans and MRS-agar was used to grow L. vulgaris. Various concentrations of these substances (0.1, 0.05 and 0.025% of miswak extract, 0.1, 0.05, 0.025 and 0.0125% of persica, 0.2, 0.1, 0.05 and 0.025% of chlorhexidine) were added to paper disks, separately, inserted into culture plates and transferred into the incubator. The inhibition zone around each disk was measured after 24 hours and the data was analyzed by the Kruskal-Wallis test.

Results

Chlorhexidine possessed antibacterial activity at all concentrations tested. It was more effective than persica and miswak at all concentrations on S. salivarius (p = 0.022 for 0.1%, 0.009 for 0.05 and 0.025%). It had greater effect than the other two tested material on S.sanguis only at concentration 0.01%. Chlorhexidine was the most effective against S.salivarius; persica was the most effective against Lactobacillus (p = 0.005) and the least effective against S. salivarius; and miswak extract was the most effective against S. salivarius and S. sanguis at concentrations 0.1 and 0.05% (p = 0.005) and ineffective against L. vulgaris. None of these mouthwashes were effective against C. albicans.

Conclusion

This study revealed that chlorhexidine remains the gold standard as an antimicrobial agent, although herbalbased mouthwashes do have marginal antimicrobial activities. It is necessary to conduct more clinical and microbiological studies focusing on periodontal pathogens and anaerobic microorganisms.

Clinical significance

Mechanical plaque control is the main way for periodontal disease prevention and mouthrinses are used to improve its efficacy. Based on the results of this study, chlorhexidine has the most antibacterial effect and although persica mouthwash and miswak are routinely used in some Asian countries their antibacterial efficacies are suspected.

Abstract

Aim

The aim of this in vitro study was to evaluate if there is any significant difference in apical leakage when gutta-percha is removed immediately after obturation for postspace preparation or after a week.

Materials and methods

Two commonly used sealers AH26 and tubliseal were used in four groups each consisting of 20 teeth each. The tooth was sectioned at the amelocemental junction to leave a root portion of 12 to 14 mm. Canals were checked for patency and prepared to No-55 K file size. Two people, using a stereomicroscope, independently evaluated each tooth-half for the extent of apical leakage.

Results

The leakage results were analyzed using a one-way ANOVA according to present study, immediate postpreparation is preferable than delayed postpreparation. The relationship of in vitro leakage measurements to the in vivo situation has not been established.

Clinical implication

Hence, immediate postpreparation is preferable than delayed postpreparation.

Salivary Immunoglobulin Classes in Nigerians with Periodontitis

[Year:2012] [Month:March-April] [Volume:13] [Number:2] [Pages:4] [Pages No:163 - 166]

PDF  |  DOI: 10.5005/jp-journals-10024-1114  |  Open Access |  How to cite  | 

Abstract

Aim

To provide information on the usefulness of salivary immunoglobulin classes in the diagnosis of periodontitis.

Materials and methods

About 5 ml of unstimulated saliva was collected from 25 newly diagnosed subjects with periodontitis and 21 sex/age-matched apparently healthy individuals into plain sample bottles. The samples were collected between 9 am and 11 am at least, 1 hour after eating or washing of mouth and levels of salivary immunoglobulin classes (IgA, IgG, IgE and IgM) were determined using enzyme-linked immunosorbent assay (ELISA).

Results

Only the mean level of IgA was significantly raised (p = 0.05) in the saliva of periodontitis patients compared with controls. The mean levels of IgG, IgM and IgE were not significantly elevated in patients with periodontitis, when compared with controls (p > 0.05).

Conclusion

This study showed that elevated salivary levels of IgA could be used as a screening tool for periodontitis.

Clinical significance

Identification of patients at risk and the diagnosis of active phases of periodontal disease remains a challenge due to lack of laboratory test routinely employed in the diagnosis and monitoring of patients with periodontal disease. This study showed that elevated salivary levels of immunoglobulin classes especially, IgA could be used as a screening tool for periodontitis.

Abstract

Aim

Relating the marginal fit of the castings, to the accuracy of the impression produced using laminated hydrocolloid impression technique, alginate and double-mixed polyvinyl siloxane. Basic objective of the study is to check the feasibility of the use of laminated hydrocolloid impression technique in the fixed partial denture.

Materials and methods

The precisely machined metal die was designed to simulate standard complete metal crown preparation. The preparation was mounted on cylindrical base of 20 mm length and diameter of 10 mm. Seven impressions were made from the each impression material onto the metal die, and total 21 impressions were obtained from all three impression materials, which were poured by the die stone, and stone die was prepared. Wax patterns were fabricated on stone dies obtained from each impression and then casting was done. All the castings were checked for the marginal fit on metal die after applying a uniform standardized load of 30 pounds using measuring microscope.

Results

Result revealed that the marginal fit of the castings obtained from group II (laminated hydrocolloid technique) and group III (double-mix polyvinyl polysiloxane) did not show the significant difference between the two of them. Marginal gap of the castings obtained from group I are significantly greater in comparison to the castings obtained from groups II and III (p < 0.01).

Conclusion

Group II (laminated hydrocolloid technique) impression material may be the choice of many clinicians over group III (double-mix polyvinyl polysiloxane) impression material. Group I (alginate impression material), though very cost-effective and easy to handle may not able to produce accurate results.

Clinical significance

The study gives overview of the best impression material that can be used clinically. Laminated hydrocolloid technique is the technique of choice.

PDF  |  DOI: 10.5005/jp-journals-10024-1116  |  Open Access |  How to cite  | 

Abstract

Aim

The aim of this study was to define the prevalence and severity of temporomandibular disorders (TMD) among Iranian dental and nondental students who attended Shiraz University of Medical Sciences.

Materials and methods

The samples consisted of 200 subjects, 100 dental and 100 nondental students (equal distribution between males and females). Subjects ages ranged from 18 to 30 years (24.07 ± 2.93). A functional evaluation was performed using the Helkimo dysfunction index (Di). Data were evaluated by the Chi-square test.

Results

Among the total study population, 71% showed some degree of dysfunction. Prevalence ratio in dental students was 80%, while in nondental students was 62% (p < 0.05, odds ratio = 0.679). With respect to gender, women (80%) were more affected than men (62%). A significant relationship was found between gender and the occurrence of TMD (p < 0.05).

Conclusion

A high prevalence of signs of TMD in Iranian university students was seen which was greater in dental students and women.

Clinical significance

The results of this study showed that the prevalence of TMD among dental students and women was significantly higher than nondental students and men. These findings might be due to poor postural style or emotional stress during dental practice.

Abstract

Introduction

Changes in hormonal levels, such as those that occur during puberty, pregnancy, menstruation and menopause, have varying effects on oral cavity. Many researchers have proposed a direct link between changing hormonal status and oral health among females.

Objectives

To study the various symptoms and clinical manifestations of oral cavity during normal course of menstrual cycle in healthy women.

Method

Our study comprised of forty healthy young women volunteers with normal menstrual cycle of 28 to 30 days. A proper menstrual history was recorded from the study subjects. The entire cycle was divided into four phases comprising of bleeding, proliferative, ovulation and secretory. All the study subjects had a menstrual cycle of 28 to 30 days. Thorough recording of oral discomforts during various phases of the cycle was done during the study period.

Results

30% of study subjects complained of aphthous ulcers, 5% had herpes labialis, 25% of them complained of depression, 8% showed gingival bleeding.

Conclusion

Complaints, like oral ulcerations, mood variations, recurrent herpetic lesions, gingival bleeding in females during normal menstrual period, are attributed to the role of female sex hormones.

Clinical significance

Lesions, like oral ulcers, recurrent herpetic lesions and increased gingival bleeding, seen in females during normal menstrual periods, could be related to hormonal turnover and therefore treated accordingly.

Abstract

Objective

The study was to examine the prevalence of dental caries and treatment needs among the orphan children and adolescents of Udaipur district, Rajasthan, India.

Methods

A descriptive cross-sectional study was conducted to assess the oral health status and treatment needs of orphan children. The lists obtained comprised of 13 orphanages consisting of 923 inmates including both sexes. The survey proforma was prepared using a self-administered structured questionnaire written in English validated through a pretested survey. The statistical software namely SPSS 15.0 was used for the analysis of the data.

Results

The prevalence of dental caries in primary teeth was found to be 49.6% and in permanent teeth was 41%. Most of the children need one surface filling followed by pulp care.

Conclusion

The unmet needs for decayed teeth were also found to be high indicating a very poor accessibility and availability of any oral health care. Clearly, it can be concluded that this community has experienced a low utilization of preventive or therapeutic oral health services.

Clinical significance

Orphanage children in India are usually taken care by NGOs or social workers who do not realize that dental care and oral health forms an integral part of children well-being. So, this paper enlighten the prevalence of dental caries and treatment needs among the orphan children and adolescents.

Abstract

Introduction

The soft tissue paradigm is placing greater emphasis on the importance of the soft tissue profile to orthodontic treatment planning. The purpose of this study was to determine the lip dimensions of a Nigerian adult population; compare the male and female values and to compare the values obtained for Nigerians with those reported for other population.

Methodology

Lateral cephalometric radiographs of 100 students (44 males and 56 females) of the College of Medicine, University of Lagos, aged 18 to 25 years were taken. Selected subjects were of Nigerian ancestry with normal occlusion and a harmonious facial appearance. The radiographs were manually traced and the upper and lower lip length and thickness of each subject was measured. Statistical analysis was carried out using SPSS, while the male and female values were compared using student's t-tests.

Results

Mean values for the lip dimensions were computed for the entire sample. Marked sexual dimorphism was observed with the males having thicker and longer upper and lower lips than the females. The Nigerian sample also had a longer upper lip and a thicker and shorter lower lip than that reported for Caucasians. However, both population had a similar upper lip thickness.

Conclusion

Cephalometric norms were developed for the lip dimensions of a Nigerian population. Marked sexual dimorphism was observed in the Nigerian population studied with the males having longer and thicker lips than the females. The lip dimensions of the Nigerian population studied differed from that reported for Caucasians and other racial groups.

Clinical significance

The lip dimensions established in this study would aid in orthodontic and orthognathic surgery treatment planning for Nigerians. Furthermore, due to the marked sexual dimorphism observed in the Nigerian population studied, gender specific and not generalized norms should be used.

Abstract

Aim

To evaluate the expression of laminin in various grades of oral squamous cell carcinoma (OSCC) in order to determine whether this protein can be used as a marker for early detection and elucidation of oral cancer.

Materials and methods

Immunohistochemical staining for laminin was done on 60 selected archival blocks of histopathologically diagnosed cases of primary OSCC and the laminin expression was compared between the different histopathological grades of primary OSCC. The statistical analysis was performed by using Chi-square (÷ square) test and Gaussiantest with a probability of p < 0.05 was considered as significant.

Results

It was observed that laminin expression decreased with tumor progression which may be correlated to the tumor aggressiveness.

Conclusion

There was a gradual decrease of laminin staining with decreasing cellular differentiation, with differentiated lesions showing a more conspicuous staining of basement membrane glycoprotein than less differentiated lesions.

Clinical significance

An understanding of how the extracellular matrix influences tumor development and invasion is fundamental in the development of new prognostic indicators and treatment strategies for oral squamous cell carcinoma.

Abstract

Background

A high incidence of dental caries and dental erosion associated with frequent consumption of soft drinks has been reported. The purpose of this study was to evaluate the pH response of dental plaque to a regular, diet and high energy drink.

Methodology

Twenty subjects were recruited for this study. All subjects were between the ages of 20 and 25 and had at least four restored tooth surfaces present. The subjects were asked to refrain from brushing for 48 hours prior to the study. At baseline, plaque pH was measured from four separate locations using harvesting method. Subjects were asked to swish with 15 ml of the respective soft drink for 1 minute. Plaque pH was measured at the four designated tooth sites at 5, 10 and 20 minutes intervals. Subjects then repeated the experiment using the other two soft drinks.

Results

pH was minimum for regular soft drink (2.65 ± 0.026) followed by high energy drink (3.39 ± 0.026) and diet soft drink (3.78 ± 0.006). The maximum drop in plaque pH was seen with regular soft drink followed by high energy drink and diet soft drink.

Conclusion

Regular soft drink possesses a greater acid challenge potential on enamel than diet and high energy soft drinks. However, in this clinical trial, the pH associated with either soft drink did not reach the critical pH which is expected for enamel demineralization and dissolution.

Abstract

Aim

To compare cyclooxygenase 2 expression (COX2-E) between normal, oral leukoplakia lesions and different grades of oral squamous cell carcinoma (SCC).

Materials and methods

Around 90 paraffin embedded blocks consisting of 45 SCC, 15 leukoplakia and 17 controls were selected for immunohistochemistry (IHC) for detection of COX2- E. COX2-E was divided in four grades, as A (0-10%), B (11-40%), C (41-70%) and D (> 70%) cellularity.

Results

Mean age of the patients was 55.17 ± 18.41 (M:57.92 ± 16.87, F:52.19 ± 19.74). A significant difference was found in COX2 expression between SCC total and, basal and spinous layers of leukoplakia (p < 0.05). COX2-E in spinous layer of normal tissue was significantly lower than SCC (p = 0.000). COX2-E was significantly different in SCC grade 3 and leukoplakia (p = 0.001) and normal tissue (p = 0.000). COX2-E was significantly higher in SCC grade 3 compared to leukoplakia (basal layer) (p = 0.000).

Conclusion

We showed a significant higher COX2-E in SCC lesions compared to leukoplakias and normal controls. In our study COX2-E was not significantly different in SCC grades 1, 2 and 3 (p > 0.05).

Abstract

Aim

The present report describes and discusses a nonsurgical technique for the removal of overextended gutta-percha.

Background

Mechanical irritation results from overextension and the overextended material used during root canal obturation could produce an inflammatory reaction with an area of rarefaction in the periapical tissues. The healing process is not affected by the presence of filling materials as it is well tolerate by the periapical tissues, but it is accepted that a higher failure rate is found in overfilled teeth.

Case report

This clinical report describes one case with an overextended gutta-percha cone and a new nonsurgical technique to remove this material.

Conclusion

The technique described is a conservative, safe and plausible option to remove extruded gutta-percha in periapical area.

Clinical significance

Overextended gutta-percha cones could increase the failure of endodontic therapy. Commonly surgical procedures are indicated to remove this overextended material, but this nonsurgical technique could be a better treatment alternative and could increase the chances of success.

Abstract

Aim

To achieve retention in severely resorbed mandibular ridges during impression making and to maintain the retention and stability of these dentures during function.

Background

No good method with adequate clinical photographs that will empower the dentist with the necessary skill has been reported in the literature.

Technique

The technique involves making a preliminary impression in alginate to record the denture bearing area clearly, doing a border moulding procedure with excess width to fill the wide sulcus present; except in the area of anterior lingual flange from second premolar to second premolar area. The anterior lingual border of the impression is then extended sublingually without interfering with the tongue function or blocking the opening of the ducts of the sublingual gland; to maintain contact with the surrounding sublingual tissue in both protruded and retruded positions of the tongue, thereby creating good peripheral seal in the most vulnerable area in the lower denture, where the seal is easily broken during tongue movements.

Conclusion

This impression technique, combined with arrangement of teeth on the center of the ridge in the posterior part, use of flattened cusp posterior teeth and contoured polish surface of denture base (Fisch concept) provide sufficient retention and stability to the dentures made on these severely resorbed ridges.

Clinical significance

Patients with severely resorbed ridges cannot be rehabilitated with implants also and so normally suffer with loose lower denture fabricated with normal border moulding procedures. These patients can be rehabilitated to a great extent properly.

Abstract

Aim

The aim of this study was oral rehabilitation of 17-yearold patient with amelogenesis imperfecta using removable overlay denture in order to satisfy her esthetic and functional expectations and enhance her self-image.

Background

Amelogenesis imperfecta (AI) is a group of genetic disorders that primarily affect the quality and quantity of amelogenesis in both primary and permanent dentitions. The main clinical characteristics are severe attrition, tooth sensitivity and unesthetic appearance.

Case report

This clinical report illustrates the oral rehabilitation of a 17-year-old girl with hypoplastic-hypomature type of AI with cobalt-chromium (Co-Cr) overlay removable partial denture (ORPD) that is one of the most economical and biocompatible replacements for noble metal and nickel-chromium (Ni-Cr) alloy.

Conclusion

The presented case report suggests that Co-Cr ORPD can be a good temporary or even permanent treatment option for AI patients with limited budget, low esthetic concerns or medical limitations.

Clinical significance

There are major advantages in cast metal ORPDs; they are simpler, less traumatic and less expensive than fixed prosthetic options. This case report supports their use in patients with amelogenesis imperfecta.
