Objectives: To evaluate the efficacy of a topical anesthetic gel containing potassium nitrate, benzocaine and tetracaine in patients undergoing non surgical periodontal therapy. Materials and Methods: The present study was a randomised, double blind, placebo controlled, split mouth design trial carried out in 300 patients. Two quadrants in each patient were selected for non surgical periodontal therapy. The drug gel and placebo were liberally applied over the teeth and gingiva on the selected quadrants and the treatment was started after two minutes. Patients were asked to evaluate their pain experience at the end of treatment of their respective quadrants using verbal rating scale. Results: The mean pain score on using the drug gel was 0.433+0.737 as compared to the mean pain score of 2.35+0.761 on using the placebo gel, and the results were statistically significant. The drug gel out performed the placebo gel. None of the patients reported of any local or systemic side effects. Conclusions: The topical anesthetic gel provided excellent pain control for the patients undergoing non surgical periodontal therapy. It can also be considered as a good option during periodontal examination and maintenance visits to increase the patients comfort.
Aim To determine microbial prevalence in the mucous membrane and prosthesis of denture wearers with and without denture stomatitis and to study its relationship with potential clinical cofactors. Materials and methods Saliva was collected from 200 patients (100 female and 100 male) wearing dental prosthesis for measurement of pH. Oral samples of the mucous membrane and of dentures were taken with sterile swab for microbiological analysis. Medical and dietary history of the subjects was recorded. Chi-square test and analysis of varience were used for statistical analysis. Results Diabetes, hypertension and high carbohydrate ingestion was observed in majority of patients. The pH average in saliva was of 5.1. The presence of C. albicans, S. aureus and S. mutans in the mucous membrane was of 55.4, 56.4 and 63.6% respectively. C. albicans was isolated in 69.7% from the prosthesis, whereas S. aureus and S. mutans were isolated in 45.3%. The isolation of C.albicans was more frequent in patients with deture stomatitis. Conclusion C. albicans, S. aureus and S. mutans frequently colonize the oral mucous of denture wearers. This is more frequently observed in patients with denture stomatitis. Clinical significance Denture stomatitis is associated to Candida albicans, different bacteria and other cofactors, such as salivary pH, carbohydrate ingestion, systemic illnesses and medication.

Aim The aim of the present study was to evaluate the in vitro caries preventive effect of fluoridated orthodontic resins under pH cycling with two types of acid demineralizing saliva. Materials and methods Brackets were bonded to 120 extracted human premolars, using Rely-a-bond (n = 40), Tru- Bond (n = 40) and Ortho-one (n = 40) orthodontic bonding agents. Each group of resin was divided into 2 subgroups (n = 20): immersion in remineralizing artificial saliva for 14 days and acid saliva with pH 4.3. After 14 days of pH cycling the caries preventive effect on the development of white spot lesion was evaluated considering the presence of inhibition zones to white spot lesions using two scores: 0 = absence and 1 = presence. Kruskal-Wallis ANOVA and Mann-Whitney U tests were used. Results Formation of white spot lesions was observed only under pH cycling using acid saliva with pH 4.3; with Rely-a-bond and Tru-Bond being significantly more effective in preventing the appearance of white spot lesions effect than Ortho-one. Conclusion The acidity of the demineralizing solution influenced the formation of white spot lesions around orthodontic brackets under highly cariogenic conditions. Rely-a-bond and Tru-bond presented higher caries-preventive effect than Orthoone. Clinical significance The development of fluoride-containing materials cannot be regarded as a permanent means to control dental caries lesions, but a complement along with other preventive methods.
