Objective:Our goal of the study was to evaluate the antibacterial properties of endodontic sealers against the E. faecalis.Materials and Methods:Six millimeters wells were made for each material in all the preinoculated petri plates. Then, the petri plates were incubated for 24 h. The zones of inhibition appeared were measured, and the measurements were put to statistical analysis.Results:EndoSequence BC Sealer, MM-mineral trioxide aggregate (MTA), and ProRoot MTA showed maximum means of diameter of zones of inhibition, whereas MM-seal and Endoseal did not show any zones of inhibition.Conclusion:EndoSequence BC Sealer was found to be a better endodontic sealer as compared to resin-based and zinc oxide-eugenol-based sealer.

Background:We face various problems while measuring the Clinical attachment level (CAL) from Cemento-enamel junction (CEJ). This study aims to record and compare the CEJ location measurements using a xed reference point (FRP) [Custom made stent] before and after ap elevation.Materials and Methods:A custom made stent and UNC-15 probe were used. Recording of CEJ location was made using a UNC-15 (Hu-Friedy) probe, before (close CEJ) and after (Open CEJ) the reflection of the flap from the lower edge of the stent in those subjects who were indicated for flap surgery, at baseline.Results:We used statistical analysis involving intra-group comparison done by Paired-‘t’ test. The close and the open CEJ measurements demonstrated a, statistically, non-significant difference. The equi-measurements of close and open CEJ numerical data were remarkably lower than the under and overestimation of measurements. Thus, despite certain disadvantages of stent, the FRP provides a simple solution for CAL measurement.Conclusion:The results of this study confirms the objective of the study and strongly suggests that CAL measurements done without FRP is subjected to great variation and the diagnostic and prognostic interpretation of CAL should be viewed seriously in periodontics.

Background:To evaluate the gingival margin position (GMP) before and after open flap debridement in different gingival thickness (GT).Materials and Methods:Twenty-seven healthy patients with moderate to advanced adult periodontitis were included in a randomized control clinical trial. A calibrated UNC-15 periodontal probe, an occlusal onlay stent was used for clinical measurements recorded at baseline, 3 month, 6 month, and 16 month. The changes in the GMP were studied at midbuccal (Mi-B), mesiobuccal (MB), and distobuccal sites. GT was measured presurgically, transgingivally at Mi-B and interdental sites, divided into 2 groups: Group 1 (thin) and Group 2 (thick).Results:In GT of ≤1 mm group, the statistically significant apical shift of GMP led to gingival recession at all study sites in the early postsurgical period of 1 and 3 months. During 6 and 16 months, the apical shift of GMP coincided with the Chernihiv Airport at Mi-B site (6 months), MB site (16 months). The gingival recession was obvious at Mi-B sites (16 months). In the GT of >1 mm, the statistically significant apical shift of GMP did not cause gingival recession at any sites throughout postsurgical (1, 3, 6, and 16 months) period.Conclusion:Thin gingiva showed apical shift of GMP leading to gingival recession as compared to thick gingiva postsurgically.

A pulp-capping agent having good antibacterial properties can have better success rate in maintaining the vitality of the tooth while treating deep carious lesions in patients.

Background and Objectives:The evaluation of gingival margin position (GMP) plays a vital role in periodontal therapy and is critical in esthetic/plastic surgical procedures revolving around restorative dentistry. Comparative evaluations of GMP measurements in various periodontal therapies are scarce. Thus, the objectives of this study are to measure the alteration in the gingival margin position following various therapies, and to compare GMP alterations among different treatment modalities from the baseline to six months after therapy.Materials and Methods:The changes in GMP were studied for MB, B, DB, ML, and L sites for SRP, curettage, and flap surgery, and for MB, B, and DB sites for crown lengthening cases at the end of one, three, and six months after therapy. The results were interpreted from baseline to one, three, and six months posttreatment.Statistical Analysis:The results were subjected to statistical analysis. Paired ‘t’-test was used for intra-group comparisons and intergroup comparisons were done by one-way ANOVA.Results:The GMP changed from baseline in all the sites at different time periods following various therapies. The net results after six months were an apical shift of GMP in SRP, curettage, and flap surgery, and a coronal shift of GMP in crown lengthening.Conclusion:GMP shows various patterns of alteration after various periodontal therapies. One should wait for the GMP to become stable before attempting any restorative procedure.
