Aim: To compare plaque removal and wear between charcoal infused bristle toothbrushes (T1) and nylon bristle toothbrushes (T2) in a randomized clinical crossover study. Materials and methods: A cross-over study was conducted in 2 phases of 6 weeks duration each with an intervening 2-week washout. Twenty-five participants meeting inclusion criteria were randomly allocated into groups A (13) and B (12). In phase 1: group A was assigned T1 and group B was assigned T2. Toothbrushing was advised twice daily for 2 minutes by modified bass technique after meals. At baseline, 3 weeks and 6 weeks the wear index (WI), plaque index (PI) and gingival index (GI) were recorded. Following washout in phase 2 group A was assigned T2 and group B was assigned T1 and the same study protocol was followed. Results: Intra-group comparison between baseline, 3 and 6 weeks by the paired t-test resulted in significant reduction in PI, GI and increase in WI (p <0.05) for T1 and T2. Inter-group comparison using the unpaired t-test resulted in WI for T1 being significantly higher (p <0.05) at 3 weeks and lower at 6 weeks (p <0.05) compared to T2. PI for T1 was significantly higher at 3 weeks (p <0.05) and lower at 6 weeks (p <0.05) compared to T2. No significant difference in GI scores between T1 and T2 at 3 and 6 weeks was observed (p > 0.05). Conclusion: Charcoal infused bristles demonstrated less wear and more plaque removal compared to nylon bristles. Clinical significance: Charcoal infused bristles demonstrate less wear compared to nylon bristles.
