UČINAK ELEKTRIČNIH ČETKICA NA TROŠENJE DENTINA

The aim of this study was to evaluate the dentine wear after brushing with powered toothbrushes with different brush head size and different load applied in comparison with manual toothbrush. Powered toothbrush Sonicare Elite with mini and standard size brush heads at 90g and 150g vertical load, and the manual toothbrush Oral-B-P35 with a vertical load of 150g was used as a control group. Toothbrushing mashine with different number of strokes was used for dentine abrasion assessment. For Sonicare-Elite with standard size head 12000 strokes was used, for Sonicare Elite with mini head 18000 and for manual toothbrush 12500 strokes. 3D-Laser scan was used for evaluation of dentine wear. The highest dentine wear was recorded using manual toothbrush (107.26&micro ; ; ; m), while the lowest using Sonicare-Elite with standard size head at 90g vertical load (47.7&micro ; ; ; m). No statistical significance was found between powered toothbrushes with: mini head (90g load), standard head (90 and 150g load) and between mini head of powered toothbrushes at 150g vertical load and manual toothbrush. Powered toothbrushes with different brush head size and different load applied caused different tooth wear: the smaller the brush head and the higher the load is, the higher the dentine wear is.
