The purpose of the pesent study was to obtain current information regarding periodontal disease and oral hygiene status. The survey was conducted in Israel amon 9th-12th grade students, 14-17 years of age. A total of 1,320 schoolchildren were examined. During the examination only periodontal status and oral hygiene were checked. Periodontal status was recorded according to Russell's Periodontal Index (PI). Oral cleanliness was assessed according to GREENE & VERMILLION'S Simplified Oral Hygiene Index (OHI-S). The mean PI found was 0.22. The results indicated an increase in the mean PI with age. No difference was found in average PI values between girls and boys. On the other hand, significantly lower mean OHI-S values were recorded for girls as compared with boys in the total study population and within the different age groups. Mean OHI-S decreased with age, indicating improvement.
本研究的目的是获取有关牙周疾病和口腔卫生状况的当前信息。该调查在以色列针对14至17岁的9至12年级学生进行。总共检查了1320名学童。检查期间仅检查了牙周状况和口腔卫生。根据罗素牙周指数（PI）记录牙周状况。根据格林和弗米利恩的简化口腔卫生指数（OHI-S）评估口腔清洁度。发现的平均PI为0.22。结果表明平均PI随年龄增加。在女孩和男孩之间未发现平均PI值有差异。另一方面，在整个研究人群和不同年龄组中，女孩的平均OHI-S值与男孩相比明显更低。平均OHI-S随年龄下降，表明有所改善。
