OBJECTIVE Toothbrush abrasion is significant in the development of tooth wear, particularly when combined with erosion. This in vitro study aimed to evaluate the impact of toothpaste slurry abrasivity and toothbrush filament stiffness on abrasion of eroded enamel. MATERIAL AND METHODS Eroded enamel samples (hydrochloric acid, pH: 2.6, 15 s) were brushed with 40 strokes in an automatic brushin...

Twelve dentulous patients, age 65 or older, with no medical or pharmacologic predisposition to gingival hyperplasia were enrolled in a controlled clinical trial to evaluate the effect of the unaided use of an ultrasonic toothbrush on supragingival plaque and gingival bleeding. Subjects used the ultrasonic toothbrush in lieu of their conventional toothbrushes for a 30-day period. Clinical measur...

Currently, there are no studies in the literature evaluating salivary fluoride retention after small amounts of fluoride gel are applied to children's teeth. Therefore, the objective of the present study was to compare salivary retention after gel application using a toothbrush or by traditional application with trays. In this crossover study, children with active caries (n = 10) were randomize...

Background: The correct position of bristles of a toothbrush requires them to be bent at an angle of 45 along with gums and teeth surfaces. This practice is quite difficult by many people especially disadvantage group of people. Aim: The objective of this study was to evaluate the perception of users on a newly designed toothbrush with two brushing surfaces where bristles were prefabricated at ...

PURPOSE To demonstrate the noninferiority of a new toothbrush head with retractile bristles compared to traditional toothbrush heads on dental models. METHODS The new toothbrush head, mounted on manual and electrical handles, presents retractile bristle groups that can singularly retract over its entire length and offer calibrated resistance. Fourteen gypsum models of dental arches, twelve wi...

OBJECTIVE To compare the efficacy of an oscillating-rotating power toothbrush with a novel brush head incorporating angled CrissCross bristles (Oral-B Triumph with SmartGuide with Oral-B CrossAction brush head) versus a sonic toothbrush (Sonicare DiamondClean) for plaque and gingivitis reduction over a six-week period. METHODS This was a single-center, randomized, examiner-blind, two-treatmen...

A cross-functional team was assembled to take on the project of developing a toothbrush that could deliver a “whole mouth clean.” As such, this brush needed to not only demonstrate superior plaque removal from teeth, it also needed to provide a means for safe cleaning of soft oral tissues. During use, the brush needed to be comfortable both in hand and in mouth, and it required contemporary est...
