Effect of an Experimental Manual Toothbrush on Plaque and Gingivits Reduction

Aim of this study was to compare the efficacy in plaque and gingivitis reduction of an experimental toothbrush (GABA International AG, T) with a standard toothbrush (ADA reference toothbrush, C) in a splitmouth (I) and a 3 months parallel study design (II). Materials and methods: 86 male subjects took part in the study. After 48h of plaque regrowth the teeth of 2 quadrants were brushed for one minute by random with one and the remaining 2 quadrants with the other toothbrush. Immediately before and after tooth brushing (I) as well as after 3 months (II) plaque (Turesky), gingivitis (Löe & Sillness) and the number of gingival lesions = 5mm and > 5mm were evaluated by one blinded exam-iner (E.B.). After that, the individuals were appointed either to the test or the control group by ran-dom (n=43 each). All participants had to follow a standardized oral hygiene regimen for the following 3 months. Results: (I) In total, plaque was reduced from 1.95 ± 0.48 to 1.02 ± 0.41 (p Parole chiave: manual toothbrush
