Background: Root dentine translucency remains the method of choice providing the most accurate results for age estimation. Conventionally, translucency is measured using calipers. In recent times, computer-based methods are proposed, which require the use of custom-built software programs. Aims and Objectives: The aim was to use a digital method to measure dentinal translucency on sectioned teeth and to compare digital measurements to conventionally obtained translucency measurements. Materials and Methods: A total of 200 extracted permanent teeth were collected and were sectioned to a thickness of 250 μm. Translucency measurements were obtained using the digital method and compared with those obtained using a caliper. Results: Correlation coefficients of translucency measurements to age were statistically significant for both methods (P < 0.001), although marginally higher correlation was observed for the conventional method (r = 0.612). Application of derived linear regression equations on an independent sample (n = 25) suggested that conventional approach is marginally better in estimating age to within 5 years of the actual age, both the methods are similar in assessing age within 5-10 years of the actual age, and digital approach is marginally better in estimating age beyond 10 years of actual age. Conclusion: The translucency measurements obtained by the two methods were identical, with no clear superiority of one method over the other.

The developments in forensic science have introduced many vital crime solving techniques over the past few decades. It has shaped the world of justice, fuelling crime investigations and signifying the progress of modern technology. This article attempts to review different aspects of forensic science and emphasise the key role it plays in determining the identity of humans through skull and bone.

Clinical decision making in the case of a partially edentulous patient with only a few teeth remaining is a challenge. There is always a social and psychological fear of being edentulous after the extraction of remaining teeth. The position and number of teeth in the arch will decide the type of treatment like extraction of the remaining teeth and fabrication of a conventional complete denture, a removable partial denture, an overdenture or an immediate denture. Custom bar supported overdenture is a good alternative treatment modality because of its improved retention, stability, better chewing efficiency and decrease in alveolar bone resorption. It also prevents the patient from the anxiety and distress associated with the extraction of remaining teeth. This case report presents the management of a patient with a bar retained mandibular overdenture opposing maxillary immediate over denture.

Introduction: The retromolar pad also called piriformis papilla is a mucosal elevation located in the retromolar area covering the retromolar triangle. After molar loss, the bony alveolar process and surrounding soft periodontal tissue remodel, mainly resorb and blend with retromolar pad. It is a key intraoral landmark in prosthodontics. Aim: The aim of this in-vitro study was to analyze the various anatomical shapes and sizes of retromolar pad in 150 completely edentulous patients between 55 to 70 years of age group. Materials and Methods: The study was conducted on 150 completely edentulous patients. The shapes of retromolar pad on the left and right side were seen and divided into pear, triangular and round shape. The comparison of the mean longitudinal diameter and transverse diameter on the right and left sides was done. The data was evaluated statistically. The chi-square test was used for the comparison between the proportions with the help of standard deviation, t-test was used for comparison between the left and the right side and ANOVA test was used for comparison between the various shapes of the retromolar pads. Results: The result showed that there was statistically significant difference among different shapes of retromolar pad and there was significant difference in mean transverse and longitudinal diameter on right and left side, the mean value of the longitudinal diameter on left and right side was 8.81 and 8.69 whereas the mean value of the transverse diameter on left and right side was 6.79 and 6.82 respectively and p-value obtained for both was 0.550 and 0.814 respectively. Conclusion: The study conclude that there are three different shapes of retromolar pad among which pear and triangular shaped retomolar pad provides more stability in lower denture because of increase surface area. © 2016, Journal of Clinical and Diagnostic Research.

Background: Apical migration of the gingival margin beyond the cement-enamel junction (CEJ) is called as gingival recession. Various classifications of gingival recession have been proposed to evaluate different degrees of damage to periodontal tissues, but do not consider the condition of the exposed root surface: presence of an identifiable CEJ and presence of root abrasion. Sometimes these lesions may be associated with enamel abrasion. Therefore, the aim of this paper is to propose the new classification of dental surface defects in gingival recession area. Methods: Two factors were evaluated to set up a classification system: presence (A) or absence (B) of cemento-enamel junction (CEJ) and presence (+) or absence (-) of dental surface discrepancy caused by abrasion (step). Four classes (A+, A-, B+, and B-) were identified on the basis of these variables. The classification was used on 1000 gingival recessions to examine the distribution of the four classes. Results: Out of 1000 exposed root surfaces, 380 showed an identifiable CEJ associated with step (Class A+, 38%); 280 an identifiable CEJ without any associated step (Class A-, 28%); 200 an unidentifiable CEJ with a step (Class B+, 20%); and 140 an unidentifiable CEJ without any associated step (Class B-, 14%). Conclusion: The proposed classification describes the dental surface defects that are of paramount importance in diagnosing gingival recession areas which might help in selecting the definite treatment approach.

Even though numerous biomaterials have been devised and employed for periodontal regeneration, it should be well understood that the root surface receptiveness to clot formation and maintenance during initial periodontal wound healing, decides the nature of the connective tissue attachment. So this study was carried out with the prime objective of assessing the initial wound healing events occurring in vivo after the application of citric acid on to the root surfaces during periodontal regenerative therapy.Thirty-two human teeth were used for this in vitro study. Two dentin blocks each measuring 4 2 1 mm were made from each tooth. These dentin blocks were planed and treated differently with Phosphate Buffered Saline (PBS), citric acid, PBS and fresh human blood, citric acid and fresh human blood and were segregated into eight groups. Finally all the dentin blocks were processed and subjected to a scanning electron microscope study.In PBS-treated samples, the dentin surface was irregular corresponding to smear layer and the dentinal tubule openings were obscured. Whereas, in those treated with citric acid revealed a smooth dentin surface devoid of smear layer and the dentinal tubular openings were clear. Further samples that were treated with PBS plus blood showed little or no fibrin network formation whereas with those citric acid plus blood showed a fine thick fibrin network formation adhered to dentinal surface.The results of this present in vitro study suggests that use of citric acid as a root conditioning agent has a beneficial effect on initial wound healing events, which are critical for periodontal regenerative therapies.
