Abstract

Aim

This study was carried out with the purpose of comparing three impression methods as to which of them placed tissues most favorably.

Methods

The methods used were Hindels method, selective tissue placement method and functional reline method. The measurements obtained were analyzed to determine which of the three impression methods placed the mucosal tissues maximally. To compare and measure tissue placements, autopolymerizing acrylic resin platforms were constructed to the height of the occlusal surfaces of the remaining teeth. 15 orthodontic buccal tubes were placed on each side of the platform. They were arranged in three sets of five and attached to the platform over selected reference regions by means of autopolymerizing resin. The selected reference areas were in anterior, middle and posterior areas of the ridge on either side.

Results

No significant difference was seen in tissue placement in the anterior middle and posterior regions in each of the three methods when each method was assessed separately. Selective tissue placement method placed the tissues maximally (7.547 mm) followed by Hindels method (7.2110 mm) and the least placement was by functional reline method (5.856 mm). Tissue placement was significantly higher in Hindels method as compared to functional reline method (p < 0.001).

Conclusion

Tissue placement was maximum in the posterior region, followed by the middle region and least in the anterior region of the mandibular ridge for all three methods. Selective tissue placement method showed the maximum overall tissue placement followed by the Hindels method and minimum placement was by functional reline method.

Clinical significance

Selective tissue placement method provided maximum overall tissue placement and can be a preferred technique for impression making for bilateral distal extension removable partial denture fabrication.

Prevalence of Chewing Side Preference in the Deciduous, Mixed and Permanent Dentitions

[Year:2011] [Month:September-October] [Volume:12] [Number:5] [Pages:4] [Pages No:339 - 342]

PDF  |  DOI: 10.5005/jp-journals-10024-1056  |  Open Access |  How to cite  | 

Abstract

Aim

This study evaluated the prevalence of the chewing side preference (CSP) in the deciduous, mixed and permanent dentitions.

Materials and methods

Three-hundred subjects were divided in three groups (n = 100): Group 1 – children with deciduous dentition; group 2—children with mixed dentition; group 3 – subjects with permanent dentition. The CSP was determined using a direct method (visual observation) developed by McDonnell et al. (2004). Descriptive statistic was used to observe the prevalence of CSP. The Pearson's Chi-square was used to investigate signicant associations between gender, presence of CSP and preferred side (right/left).

Results and conclusion

Eighty-seven percent of group 1 had a CSP. Eighty-two percent of group 2 had a CSP. Seventy-six percent of group 3 had a CSP. There was no statistically significant association between presence of CSP and gender in all groups. There was no statistically significant association between preferred side (right/left) and gender in all groups.

Clinical significance

There is a higher prevalence of subjects in deciduous, mixed and permanent dentition that presented chewing side preference. The early diagnosis of the presence of chewing side preference can prevent the unilateral chewing pattern with prophylactic therapy applied to the first teeth (deciduous).

Biomechanical Aspects in Late Implant Failures: Scanning Electron Microscopy Analysis of Four Clinical Cases

[Year:2011] [Month:September-October] [Volume:12] [Number:5] [Pages:5] [Pages No:356 - 360]

PDF  |  DOI: 10.5005/jp-journals-10024-1059  |  Open Access |  How to cite  | 

Abstract

Aim

The aim of this work is to analyze by scanning electron microscopy implant components that have mechanically failed in vivo.

Materials and methods

Three clinical cases are presented relative to single lateral posterior restorations supported by implants and a case of a mandibular overdenture supported by two implants. In all the reported cases the presence of an incongruous occlusal load caused the fracture of the components of the implant supported restorations.

Conclusion

From the analysis of the cases examined in this study, it is deduced that the functional overload influences the biomechanical behavior of the prosthetic rehabilitation supported by an implant and may, in less fortunate cases, determine the failure following the fracture of the connecting screws and/or the fixture.

Evaluation of the Light Energy Transmission and Bottom/Top Rate in Silorane and Methacrylate-based Composites with Different Photoactivation Protocols

[Year:2011] [Month:September-October] [Volume:12] [Number:5] [Pages:7] [Pages No:361 - 367]

PDF  |  DOI: 10.5005/jp-journals-10024-1060  |  Open Access |  How to cite  | 

Abstract

Aim

This study investigated the influence of different composite resin organic matrix (methacrylate – Filtek Z350 XT and silorane – Filtek P90) on light energy transmission through the composite and bottom/top rate.

Materials and methods

A light-emitting diode (New Blue Phase), light-curing unit was used with different photoactivation protocols (high-continuous mode – HCM, 1400 mW/cm2 for 20 seconds; low-continuous mode – LCM, 700 mW/cm2 for 40 seconds; and soft-start mode – SSM, 140 mW/cm2 for 5s followed by 39 seconds for 700 mW/cm2). Twenty specimens were prepared for each composite. The light energy transmission through the composite was calculated (n=10). The bottom/top rate of the same specimen was calculated (n=10). The data were compared by Tukey's test in different tests (light energy transmission through the composite and bottom/top rate).

Results

The light energy transmission through the Filtek Z350 XT composite (HCM – 576 mW/cm2, LCM – 238 mW/cm2, SSM – 232 mW/cm2) did not show statistical difference when compared with Filtek P90 composite (HCM – 572 mW/cm2, LCM – 233 mW/cm2, SSM – 230 mW/cm2). The bottom/top rate of the Filtek Z350 XT composite (HCM – 88.98%, LCM – 90.94%, SSM – 89.92%) was statistically higher than that of the Filtek P90 composite (HCM–77.29%, LCM–77.51%, SSM– 77.79%).

Conclusion

Light energy transmission through the composite was not influenced by the use of different dental composite restoratives. However, the bottom/top rate of the composites was influenced by the use of different dental composite restoratives.

Clinical significance

Insufficiently polymerized composite resin may present a large number of problems. For this reason, dental composite resins should have the similar deep surface polymerization as the top surface in dental restorations.

Abstract

Aim

To evaluate the interference of the intracanal medication Calen® (SSWhite, São Paulo, Brazil) on the filling of simulated lateral canals.

Materials and methods

Twenty human anterior teeth were used. Before the endodontic filling procedures the access of cavity was made, and after this root canals were made in all the teeth to simulate the presence of lateral canals. After preparation, the teeth were randomly divided into two groups (n=10). In group I, the root canal system was filled directly after chemicalmechanical preparation; in group II, endodontic treatment was performed in multiple sessions, and after preparation the calcium hydroxide-based intracanal medication Calen® was inserted. After the period of 7 days, the root canals were vigorously irrigated and then they were filled. Next, the teeth were radiographed to verify the quality of the filling.

Results

The results demonstrated that the teeth treated in a single session, without calcium hydroxide medication, presented 47 canals out of 60 with radiographic evidence of filling, whereas the teeth in which intracanal medication was used, only 07 presented a radiographic image compatible with filling (p < 0.05).

Conclusion

The use of the calcium hydroxide-based medication Calen made it difficult to obtain a hermetic filling of the root canal system.

Clinical significance

The clinical significance of this work basing on the fact that once the dentist knowing that property obliteration of calcium hydroxide can be taken care when they are used in the presence of lateral canals.

Efficacy of Two Methods for Restorative Materials’ Removal in Primary Teeth

[Year:2011] [Month:September-October] [Volume:12] [Number:5] [Pages:7] [Pages No:372 - 378]

PDF  |  DOI: 10.5005/jp-journals-10024-1062  |  Open Access |  How to cite  | 

Abstract

Aim

This in vitro study aimed to compare the time required for removal, the presence of residues of restorative material, tooth structure loss and dental surface morphology after removal of composite resin and amalgam restorations from occlusal cavities in primary molars using conventional high-speed bur and CVDentus® ultrasonic diamond tips.

Materials and methods

A total of 37 primary molars were allocated into four groups: Group 1 (n=9)—amalgam restorations removed using high-speed bur; Group 2 (n=10)—amalgam restorations removed using ultrasonic tip; Group 3 (n=8)— composite resin restorations removed using high-speed bur; Group 4 (n=10)—composite resin restorations removed using ultrasonic tip. After being restored, teeth were sectioned and analyzed through stereoscopic microscope images before and after restoration removal. The structural loss was analyzed by software of image analysis, and an examiner assessed for the presence of residues. Scanning electron microscopy was used to evaluate the morphology. Time and structural loss values were compared using ANOVA, and the percentages of samples with residues using Fisher test.

Results

There was no statistically significant difference in the tooth structure loss among different methods and restorative materials, as well as in the presence of residues of restorative material. However, diamond burs were faster than the ultrasonic method for both materials. Differences in dental morphology were observed between the methods of restoration removal, but not related to the restorative material.

Conclusion

Both conventional high-speed bur and ultrasonic diamond tip methods remove similar amounts of tooth structure, but the removal performed with diamond tips in ultrasonic devices is slower.

Clinical significance

This study shows that both ultrasonic and conventional high-speed bur methods for removing restorations generate similar loss of sound dental tissue, but the former is slower.

Abstract

Aim

Ankaferd Blood Stopper (ABS), as an herbal complementary medicine, has been approved for the management of clinical hemorrhages in Turkey, including dental interventions. Basic, preclinical and clinical studies disclosed the settings of the topical hemostatic use of ABS. The aim of this study is therefore to assess the efficacy and safety of ABS as an antihemorrhagic agent in the bleedings associated with dental procedures in patients with normal and impaired hemostasis.

Materials and methods

ABS has been topically applied by homogeneously spraying to the 113 patients during dental interventions within its on-label indications. A median of 0.5 ml (IQR:0.5-1 ml) ABS was administered after tooth extraction with prolonged hemorrhages.

Results

After the administration, bleeding stopped in less than 10 seconds in 59 (52.2%) patients, and below 22.5 seconds (IQR: 18, 8-30) in 54 patients (47.8%). A total of 141 procedures were performed in these 113 patients, and nearly 72.5 ml ABS was used with a total cost of 98 €.

Conclusion

ABS as a new herbal medicine was found to be an effective method for controlling bleeding related to dental procedures. No patient had wound infection and the healing process appeared to be normal. Topical ABS could be useful for the local hemostasis and wound healing in periodontal surgeries.

Clinical significance

In this prospective study ABS, for the first time, has demonstrated its potential for being an effective hemostatic agent for the management of bleedings due to dental procedures.

Abstract

Aim

Indirect restorations are increasingly used in dentistry, and the cementation interface is possibly the most critical region of the work. The objective of the present work was to evaluate the influence of exposure to a culture medium containing S. mutans on the hardness and solubility of four different cementing agents (zinc phosphate, glass ionomer, glass ionomer modified with resin and resin cement).

Materials and methods

Test specimens composed of these cements were exposed for 30 days in a culture medium containing S. mutans. After leaching, the test materials were assessed in terms of their solubility (loss of mass) and Knoop (KHN) microhardness. Changes in surface morphology were identified using scanning electron microscopy (SEM).

Results

The resin cement showed no significant solubility and its hardness increased following exposure and leaching, while the zinc phosphate cement was the most soluble and its hardness decreased after exposure to the culture medium. SEM analyses identified morphological alterations on the surfaces of the test materials that were compatible with the solubility results.

Conclusion

It is concluded that resinous cements perform better than water-based cements when exposed to acidic conditions.

Clinical significance

The effects of acids from Streptococcus mutans can interfere with the efficiency and properties of some cements used for fixation of indirect restorations, exposed to the buccal environment.

Abstract

Aim

The purpose of the present article is to discuss four different case reports of the so-called calcifying odontogenic cyst and highlight the histopathological diversity of the same.

Background

Calcifying odontogenic cyst was first described by Gorlin et al in 1962. Ever since, its identification as a specific odontogenic lesion, controversies and confusions have existed regarding the relationship between cystic lesions and solid tumor masses that share cellular and histomorphologic features. Although several classifications were proposed, dilemma still persists regarding the nature of these lesions as cysts, neoplasms and even malignancies.

Conclusion and clinical significance

The classifications discussed for the so-called calcifying odontogenic cyst by various authors have only added to further confusion rather than enlightening. Though many authors state that classifications remain only an academic exercise, it definitely has significance in treatment planning. Emphasis should, therefore, be laid on a universally accepted classification.
