Interaction between toothbrushes and toothpaste abrasive particles in simulated tooth 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....

In vitro tooth cleaning efficacy of electric toothbrushes around brackets.

This in vitro study assessed the cleaning efficacy of different electric toothbrushes around upper incisor brackets. Standard and Mini Diamond brackets were fixed on black-stained teeth. The teeth were coated with white titanium oxide and brushed in a machine twice for 1 minute each. Twelve different brush heads with either a wiping or an oscillating-rotating action were tested. After brushing,...

In vitro tooth cleaning efficacy of manual toothbrushes around brackets.

The purpose of this laboratory study was to assess the potential cleaning efficacy of nine different toothbrushes around brackets in vitro. Standard and Mini Diamond brackets were fixed on coloured teeth in a special model, coated with white titanium oxide, brushed in a machine with different manual toothbrushes (three different types: planar, staged, and v-shaped bristle field), and tested wit...

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) ...
