Clinical Performance of Zirconia Reinforced versus Conventional Viscous Glass Ionomer in Class I Cavities of Geriatric Patients: A 1-year Randomized Controlled Clinical Trial.

Background: For the elderly population, efforts are made to simplify the restorative procedure while maintaining good clinical performance. Glass ionomer (GI) cements are showing signs to fulfill many of these qualities. With their new properties and ease of use, they can be developed further to become a useful group of materials to overcome the problems of elderly patients.

Tubular occlusion of simulated hypersensitive dentin by the combined use of ozone and desensitizing agents.

Objective: Ozone was suggested for treatment of hypersensitive dentin. The purpose of this study was to investigate the effect of ozone, with or without the use of desensitizing agents, on patency and occlusion of simulated hypersensitive dentin.

Materials And Methods: Sixty standardized dentin slabs were randomly divided into six groups: distilled water (Control), ozone treatment, fluoride desensitizer (ALLSolutions, Dentsply), oxalate desensitizer (D/Sense Crystal, Centrix), combined use of ozone/fluoride and combined use of ozone/oxalate.
