项目摘要

The purpose of this study is construction of efficient periodontal examination system. Three studies were carried out for the purpose.Study 1 : Periodontal evaluation by CPI examination was compared panoramic radiography examination evaluation. 225 persons (62 male and 163 female (average age 56.6 ± 8.8 years old) were examined by both CPI and panoramic radiography examination. The bone absorption rate in CPI code 3,4 groups ware significant higher than CPI code 0-2 groups (p<0.01). The bone absorption rate in CPI code 4 group was significant higher than CPI 3 group (p<0.01).Study 2 : A purpose of this part study is to change from disease oriented oral examination to problem oriented oral examination. 245 female (average age 24.1 ± 5.3 years old) were inspected by two colors chewing gum (30,40,50,60 times mastication) as mixture ability. As for effective the screening standard of mixture gum, was supposed that 30 and 60 times mastication method. It was suggested that the criterion of screening was "2" "3" as excellence groupStudy 3 : The relation between mixture ability and oral health condition were studied at this part study. 81 male and 254 female were inspected oral health condition and mixture ability (30 and 60 times mastication). As relation of mixture ability, number of present tooth and CPI was extracted.These results were suggested that evaluation by diversified examination of periodontal disease was contributed construction of efficient periodontal examination system.

本研究旨在建立高效的牙周检查系统。为此目的进行了三项研究。研究1：将CPI牙周检查与全景x线检查进行比较。225例患者（男62例，女163例，平均年龄56.6±8.8岁）行CPI和全景x线检查。CPI编码3、4组骨吸收率显著高于CPI编码0 ~ 2组（p<0.01）。CPI编码4组骨吸收率显著高于CPI编码3组（p<0.01）。研究2：本部分研究的目的是从疾病导向的口腔检查转变为问题导向的口腔检查。对245名女性（平均年龄24.1±5.3岁）进行两种颜色口香糖（咀嚼次数分别为30、40、50、60次）混合能力检测。对于混合胶的有效筛选标准，提出了30次和60次咀嚼法。建议筛选标准以“2”、“3”为优秀组。研究3：本部分研究探讨混合能力与口腔健康状况的关系。分别对81名男性和254名女性进行口腔健康状况和混合能力（咀嚼次数分别为30次和60次）检查。作为混合能力的关系，提取出当前牙数与CPI的关系。结果表明，通过牙周病的多样化检查进行评价有助于构建高效的牙周检查体系。
