A cross-sectional survey, using cluster sampling technique, of slum population, was done to explore the oral health status and the prevalence of common oral diseases. A close ended questionnaire comprising Decayed, Missing and Filled Teeth (DMFT) Index, Gingival Index (Löe and Silness) and Plaque Index was applied to evaluate and record oral diseases, in both male and female population, covering a wide range of age groups. Clinical examination was carried out in different shum set ups, including slum schools by trained and calibrated examiners. Three thousand nine hundred and four (3904) slum dwellers participated in the survey. Prevalence of Caries was expressed in mean DMFT, recording of gingival status followed the method of Löe and Silness, oral hygiene status was evaluated using Plaque index. Mean decayed component, of the DMFT, was significantly higher than filling and missing component. Both decayed and missing components showed increasing trend, and filling components decreased as the age progressed. Prevalence of gingivitis and plaque accumulation was remarkably high among slum dwellers. Significantly high level of common oral diseases was found among Tongi slum dwellers.
采用整群抽样技术对贫民窟人口进行了横断面调查，以探究口腔健康状况和常见口腔疾病的患病率。应用一份包含龋失补牙指数（DMFT）、牙龈指数（洛和西尔斯）和菌斑指数的封闭式问卷，对不同年龄组的男性和女性人群的口腔疾病进行评估和记录。由经过培训和校准的检查人员在不同的贫民窟环境中进行临床检查，包括贫民窟学校。3904名贫民窟居民参与了此次调查。龋病患病率以平均DMFT表示，牙龈状况的记录采用洛和西尔斯的方法，使用菌斑指数评估口腔卫生状况。DMFT中的平均龋坏成分显著高于补牙和失牙成分。龋坏和失牙成分均呈上升趋势，而补牙成分随着年龄的增长而下降。贫民窟居民中牙龈炎和菌斑积聚的患病率非常高。在通吉贫民窟居民中发现常见口腔疾病的水平显著较高。
