Objective: The purpose of this study was to evaluate the in vitro effectiveness of two different bioglass-containing commercial desensitizing toothpastes together with a fluoride containing dentifrice as a control on dentinal tubule occlusion before and after a citric acid challenge and immersion in artificial saliva.
Methodology: Forty-five dentine specimens with patent tubules were randomly divided into 3 groups (n=15), Group A: brushing with Biomin (Elsenz®); Group B: brushing with Novamin (Sensodyne Repair®); and control Group C: brushing with fluoride (Colgate Total®). In each group, treated specimens were further subdivided into Subgroup A: directly underwent SEM, Subgroup B and C soaked in 0.3% citric acid and artificial saliva (Wet mouth®) for 5 minutes respectively. The percentage of tubule occlusion (%OCT) of represen.. View More»
