Aim: The purpose of this clinical trial is to clinically evaluate the plaque removal efficacy of three commercially available tooth brushes.

Material and Methods: The study group consisted of fifty seven subjects with age ranging from 15 to 28 years distributed into 3 different groups, Group A(multi angle cross bristled toothbrush), Group B(circular bristled toothbrush), Group C(z shaped bristles toothbrush) .Study was single blinded, randomized clinical trial. Rustogi modified navy plaque index (RMNPI) and Sulcular bleeding index (SBI) were assessed at baseline, 7th day and 21st day.

Results: All brushes showed significant reduction in plaque score over 3 weeks period. Comparison of mean plaque index and Average SBI between the three groups shows that Group C has the highest value of 0.9086(RMNPI) and 0.9204(SBI). However, the reduction of plaque scores is greater in Group C(oral B shiny clean) when compared to other groups.

Conclusion: The data derived from this clinical trial shows that all the tooth brushes has shown decrease in plaque scores. In comparison, z shaped bristles toothbrush [Group C] has some beneficial effects in reduction of plaque scores.
