Objective: To investigate the periodontal health conditions by using community periodontal index (CPI) and analyze the effects of related risk factors.
Methods: By stratified random sampling procedure, a total of 1 183 subjects aged 35-74 were recruited from 13 neighbour community and accepted structured interview and periodontal examination.
Results: The percentage of edentulous jaws was 2.3% (27/1 183). For the remaining 1 156 people, the percentage of subject with a highest CPI scores of 0,1,2,3,4 were 0.3%, 0.2%, 46.3%, 31.9%, 21.3%, respectively. At the sextant and tooth level, the numbers of healthy, bleeding, calculus, shallow pocket, deep pocket and missing pocket were 0.26, 0.25, 3.56, 1.06, 0.39, 0.48, and 3.32, 2.02, 15.43, 2.60, 0.70, 3.93, respectively. By multivariable logistic regression models, many risk indicators such as age, gender, smoking, the knowledge, attitudes and practices (KAP) status, etc. were demonstrated to be related to the distribution of deeper and missing pockets.
Conclusion: The adult periodontal conditions of urban community were serious and affected by some demographic and behavior risk factors. More than half (53.2%) of the examined subjects require complex periodontal treatments.
