OLIVEIRA, Luciana Butini et al. The cleaning efficiency of a conventional and a triple-headed toothbrush in children. RGO, Rev. gaúch. odontol. (Online) [online]. 2011, vol.59, n.2, pp. 259-263. ISSN 1981-8637.

Objective The objective of this study was to compare the efficacy of bacterial plaque removal with conventional (Bitufo® 22, Bitufo, Itupeva, Brazil) and triple-headed (DenTrust, Dental HealthWay Inc., Newport, USA) toothbrushes. Methods Twenty children aged 4 years old participated in this crossed study, with weekly intervals. The quantity of biofilm was evaluated before and after toothbrushing by children for 1 minute each arch. A fluorescent light-cured bacterial plaque revealer (Plaque Test® Vivadent, Ivoclar Vivadent AG, Schaan, Principality of Liechtenstein) was used to report Greene and Vermillion1 index for free smooth surfaces, and Rodrigues et al.2 index for occlusal surfaces. Data were submitted to ANOVA. Results In spide of the employed toothbrush, there was statistically significant difference on plaque removal between smooth or occlusal surfaces (p=0.000). The triple-headed and the conventional type cleaned occlusal surfaces similarly. However, the triple-headed toothbrush removed more plaque on buccal surface than the conventional type (p<0.05). The triple-headed toothbrush removed more plaque on the buccal surface (p<0.0001). The conventional and the triple-headed promoted a similar plaque removal both in anterior buccal areas. The triple-headed toothbrush was more effective than the conventional type on the posterior area (p<0.0001). Conclusion It was concluded that effective plaque removal was achieved by the children with both toothbrushes; however the triple-headed toothbrush had a better performance
