The effect of toothbrushing on a hybrid composite resin

Research output: Contribution to journalArticlepeer-review


This study observed the effect of various toothpastes on a hybrid composite resin to determine the difference in surface roughness as measured by a profilometer. Slurries (100 gm dentifrice/100 gm H2O) of eight toothpastes were tested by brushing composite resin samples 20,000 times and recording changes in surface smoothness with a profile meter. The surface topography of a hybrid composite resin was altered by routine toothbrushing; the effect of Colgate toothpaste was a statistically smoother surface than found with the other dentifrices; and the surface topography of acrylic resin was altered less by Colgate, Crest, Viadent, and Supersmile than the more abrasive Shane, Sensodyne, Rembrandt, and Topol dentifrices.
