Methods: A toothbrush used once a day for 50 kindergarten children was collected for 1 week and 4 weeks. The mean value and standard error of toothbrush wear index (WI) and wear rate (WR) were analyzed according to the criteria. SEM analysis was performed to observe the shape of the tip of the bristles. Statistical program SPSS was used for analysis. Results: In the wear index (WI) measurement result, there was a significant difference according to the usage period between 1 week and 4 weeks. The average wear rate was 0.840 ± 0.344 and 1.458 ± 0.390 at 1 and 4 weeks, respectively. Thereby, showing a large difference. In terms of the wear rate, the toothbrushes used by boys for 4 weeks showed a larger wear rate than that of the girls.
