The objective of this study was to determine the antimicrobial activity of type III gypsum at three different chloramine-T concentrations and to ascertain the most effective concentration to be added for optimum inhibitory activity against Candida albicans. MethodTen discs of type III gypsum were fabricated for each group. Standard type III gypsum without any disinfectant was used for the control group. For the experimental group, an admixture of chloramine-T and standard dental stone was employed in varying w/w concentrations (0.1%, 0.25%, and 0.5%). Discs were placed in a petri dish containing Sabouraud dextrose agar lawned with Candida albicans culture and incubated for 24 hours. The zone of inhibition created around the discs was measured and evaluated. ResultThe mean zone of inhibition (mean ± standard deviation) in the control group was 0 mm; 0.70±1.05 mm in group 1 (0.1% w/w concentration), 2.70 ± 2.35 mm in group 2 (0.25% w/w concentration), and 20.80 ± 1.68 mm in group 3 (0.5% w/w concentration). A one-way ANOVA test showed that there was a significant difference in the inhibition zone created around all groups (p < 0.05), with the discs of group 3 yielding the most positive results. ConclusionThe addition of 0.5% chloramine-T to type III gypsum showed the most promising result, out of the concentrations tested, as a self-disinfecting dental stone and could be used for further investigations.

Alveoloplasty is one of the common pre-prosthetic surgical procedure carried out in dental surgical practice setups. A. T. Willard in 1853 advocated reduction of the alveolar ridge to bring about the complete proximity of soft tissues over the alveolus. Sir O. T. Dean first proposed “Intra-septal alveoloplasty” in the American Dental Association journal in 1936 so, named as Dean's alveoloplasty. The objective of Pre-prosthetic surgeries provide adequate bony tissue support for the placement of complete dentures. the characteristics of ideal denture base are adequate bony support with proper soft tissue coverage, no undercuts, no sharp ridges. Preprosthetic surgical treatment must begin with a thorough history and physical examination of the patient. The aim of the alveoloplasty procedure is used for recontouring of bony irregularities at the time of extractions or after initial healing. This case report illustrates case of a 71 year old healthy male. On examination who revealed irregular bony spicules on the edentulous ridge. After complete evaluation, alveoloplasty procedure was performed to smoothen the ridge. Proper diagnosis of the condition of edentulous ridges are important for successful fabrication of complete dentures. Every effort should be made to ensure that both the hard and soft tissues are developed in a form that will enhance the patient's ability to wear a denture.

Purpose: Antioxidants are nutraceuticals that reduce the concentration of reactive oxygen species and thereby reduce the inflammatory burden. The current randomized controlled trial was designed to evaluate the clinical efficacy of commercially available antioxidant formulations, oxitard and lycopene tablets as adjuncts to scaling and root planning in the management of chronic periodontitis. Materials and Methods: Forty-five chronic periodontitis patients were randomly divided into three groups, namely Group A – only scaling and root planing (SRP), Group B – SRP with oxitard tablet, and Group C – SRP with lycopene tablet. Clinical parameters – plaque index, gingival index, probing pocket depth, and relative attachment level were evaluated at baseline, 1 month, 3 months, and 6 months. Results: All groups significantly reduced clinical parameters from baseline to 6 months (P < 0.05). Intragroup analysis showed Group B and Group C to be significantly better than Group A (P < 0.05), whereas Group B showed similar results when compared to Group C (P > 0.05). Conclusion: Oxitard and Lycopene showed better improvements in clinical parameters when compared to SRP alone. Thus, both oxitard and lycopene can be potential adjuncts to SRP in the treatment of chronic periodontitis in the near future.
