Influence of fluoride mouthwash containing nanohydroxyapatite on the dentin interface of direct restorations: A randomized controlled crossover in situ study

Introduction: Toevaluatetheinfluence of afluoride mouthwash containing nanohydroxyapatite on the dentin bonding interface microhardness of direct resin composite restorations in situ. Methodology: Forty human premolars were sectioned and restored with a three-step adhesive system or a self-etch adhesive system and a conventional resin-based composite. After the initial microhardness measurements on the samples’ dentin interface, the restored […]

Effects of exposure time and exposure distance on the micro-mechanical properties of light cured pit and fissure sealants

Introduction: The study aimed to perform comparative measurements on the effect of exposure time and exposure distance on the micro-mechanical properties Vickers hardness (HV) and indentation modulus (E) of light cured, resin-based pit and fissure sealants. Material and Methods: Thirteen pit and fissure sealants were selected. Combinations of three clinically relevant exposure times (10, 20, […]
