Interactions between toothbrush and toothpaste particles during simulated abrasive cleaning

Particle Motion and Stain Removal during Simulated Abrasive Tooth Cleaning

Cleaning, abrasion, and polishing effect of novel perlite toothpaste abrasive.

OBJECTIVE This study was intended to optimize perlite particle size and morphology for better tooth cleaning and lower tooth abrasion, and to evaluate the performance of a whitening toothpaste containing the optimized perlite abrasive for tooth cleaning, abrasion, and polishing. METHODS Perlite toothpaste abrasive samples were prepared by air classifying a commercial expanded perlite product....

Interaction between toothpaste abrasivity and toothbrush filament stiffness on the development of erosive/abrasive lesions in vitro.

OBJECTIVES To investigate the loss of enamel and dentin surface caused by the interaction between abrasives in toothpaste and toothbrush filament stiffness. METHODS The study followed a 2 (high-level or low-level abrasive; silica) × 3 (filament stiffness; soft, medium or hard) × 2 (cycling time; 3 or 5 days) factorial design. Polished bovine enamel and dentin specimens (n = 8 each per group) ...

Cleaning efficacy of a new electric toothbrush.

PURPOSE To evaluate the cleaning efficacy of a new electric toothbrush and new brush head design, using a robot system to simulate normal clinical toothbrush use. MATERIALS AND METHODS The study compared the new oscillating/rotating/pulsating electric toothbrush (Braun Oral-B 3D Plaque Remover) comprised of the D15 handle and new EB15 brush head, with the clinically established oscillating/ro...
