The purpose of this study is to investigate the wear index of toothbrush and related factors in the university students. A self-reported questionnaire was completed by 573 university students from March 16 to April 10, 2015. The questionnaire consisted of general characteristics of the subjects, wear index, and wear rate of the toothbrush. The wear index of 46.9 percent was above 0.400, and the average wear index was $0.403{\pm}0.20$. Overall, the wear index of the toothbrushes was high. 2. As a result of measuring the wear rate of the toothbrushes, the wear rate of 70.4 percent stood at 1 and 2. The average wear rate stood at $1.620{\pm}0.74$. Overall, the wear rate of the toothbrushes was high. 3. As for wear index and wear rate by gender, the wear index and wear rate of the toothbrushes used by the male students were larger than those of the toothbrushes used by the female students. The wear index and wear rate were significantly higher when the toothbrush replacement period was longer. Given the findings of the study, efficient oral health education on the right toothbrush management should be provided for college students to manage their toothbrushes properly.
