Comparison of the effectiveness of two manual toothbrushes: Conventional design versus double-sided toothbrush design. A pilot study.

OBJECTIVES: Dental hygiene is the most effective method in the prevention of oral diseases. However, most patients do not use the recommended teeth brushing techniques and/or time brushing is insufficient. With this objective, modifications in conventional toothbrushes have been developed to deal with these findings. The aim of this study was to compare plaque removal effectiveness of a manual toothbrush with a modified head (MTMH) with a wrap-around design versus a conventional manual toothbrush. METHODS: This pilot prospective clinical study was designed according to STROBE guidelines. The patients suspended oral hygiene habits for 24 h (baseline). Subsequently, the teeth were brushed for 60 s. Both toothbrushes followed the same study procedure, separated by 1 month. Plaque-removing effectiveness was measured before and after tooth brushing using the modified O'Leary Plaque Index (PI). RESULTS: Seven patients were included in this pilot study. The mean age was 37.66 ± 10.68 years. PI mean differences between baseline and after brushing were 51.99% ± 16.43 for MTMH and 27.93 ± 6.85, for conventional toothbrush (p = 0.0013). After brushing, mean PI values were 18.36% ± 6.95%, and 37.61% ± 10.57% respectively (p < 0.001). CONCLUSION: Within the limitations of the present study, it can be concluded that the effectiveness of plaque removal by using MTMH is significantly higher than the conventional manual toothbrush.
