Objectives. Toothbrushing is the most fundamental self-help oral care, essential for the removal of dental plaque and food debris which can lead to caries or periodontal diseases. In order for patients to effectively select ideal toothbrush and maintain oral health, this study investigated the efficacy of different toothbrushes available on the market in the removal of dental plaque. Methods. A total of 156 pieces, from each of the three different types of standard manual toothbrushes and three slim-bristle type brushes for adults were randomly selected to be used as experiment units. The bristles of the different brushes were analyzed through a number of different processes. Data analysis was performed with Kruskal Wallis test and Man-Whitney`s U-test, Multiple linear regression at the significance level of alph=0.05. Results. The average surface area from which the artificial dental plaque was removed using the standard manual toothbrushes was 116.41 mm2 and using the slim bristle toothbrushes it was 121.82 mm2. The average buccal surface area from which the artificial dental plaque was removed using the standard manual toothbrushes was 86.93 mm2, and 88.11 mm2 using the slim bristle the slim bristle toothbrushes. The average dental sub-gingival area from which the artificial dental plaque was removed using the standard manual toothbrushes was 4.95 mm2 and 5.32 mm2 for the slim bristle toothbrushes. The average proximal surface area from which artificial dental plaque was removed using the standard manual toothbrushes was 24.79 mm2, and 28.38 mm2 for slim bristle ones. A statistically significant difference between the standard manual toothbrushes and the slim bristle was detected in the proximal surface (p＜0.05). For the group consisting of the standard manual toothbrush, It was found that the smaller the difference in the length of implant brush, the greater the amount of plaque that was removed (p＜0.05). Conclusions. According to the findings of the study, the factors influencing effective toothbrushing and brush designed indicate a need for further studies.
