Aim: The aim of this 12 week, single-blind clinical trial was to compare the efficacy of Manual (Oral-B Pro Health Gum care®), Powered (Oral-B Cross action Power Dual®) and Charcoal (Colgate slim Soft Charcoal®) toothbrushes in plaque control. Materials and Methods: 60 systemically healthy students were selected at random among the students of a Dental College, living under similar environment and dietary conditions. Plaque and calculus were removed professionally and three varieties of toothbrush were distributed among them. Plaque index (PI), sulcus bleeding index (SBI) and gingival index (GI) were assessed at baseline, 3, 6 and 12 weeks. Assessment of colony forming units (CFU) was done at baseline and 12th week. The learning effect over a period of time was also assessed. Results: Over the 12-week period, PI reduced significantly (P < 0.001) with % reduction in plaque from 47% to 59%, 41% to 53% and 45% to 55% for manual, powered and charcoal brush. A significant reduction in GI and SBI was also seen with all the brushes. An insignificant difference in PI, GI and SBI was seen between the brushes. CFU count before and after brushing reduced gradually and statistically significantly (P < 0.001) for all the brushes; however, by end of 12th week period, there was no significant difference (P > 0.05). The learning effect increased from 35% to 60%, 24% to 56% and 31% to 58% for three brushes, respectively, but was more pronounced for powered brush. Conclusion: It can be concluded that all the three brushes (manual, powered and charcoal) are clinically effective in removing plaque, with learning effect more pronounced for powered brush and if proper technique is followed, no brush is superior to the other.
