title: Comparison of periodontal health status and oral health behavior between Japanese and Chinese dental students.
abstract: A survey was carried out to compare periodontal health status and oral health behavior between Japanese and Chinese dental students. Subjects consisted of 118 students at Nihon University School of Dentistry and 92 students at the school of Stomatology, Nanjing Medical University. Saliva occult blood test was performed to classify whether subjects may have periodontal disease. Further questionnaires were given to evaluate different lifestyles and oral hygiene habit. The positive rate of the saliva occult blood test in Japanese dental students was 13.6%, and that of Chinese dental students was 43.5%. Bleeding from gingiva as a subjective symptom was as follows: Japansese 7.6%, Chinese 37.0%. Japanese dental students brushed for 13.5 min each day. The rate for Chinese students was 4.6 min. Use of interdental devices was as follows: Japanese 33.1%, Chinese 7.6%. Differences of periodontal disease rates between Japanese and Chinese dental students are thought to be differences in oral hygiene, indicating the need for improvements in hygiene measures in Nanjing City. The establishment and strengthening of oral hygiene education, including the importance of tooth brushing for prevention of periodontal disease, has been proposed.
