Abstract

The aim of this study is to survey the need, the utilization, and the influencing factors of dental services for children in selected areas in Chongqing province by investigating their oral health status. The survey will provide references for preventive oral health care in targeted Chongqing areas, which may improve the level of oral health among pre-school children. Random cluster sampling was utilized according to standards of the Fourth National Oral Health Epidemiological sampling survey, and 1 300 children between the ages of three and four years old from 24 kindergartens in 12 subdistricts of three areas in Chongqing were interviewed for free dental checkups and to participate in the survey. The questionnaires were designed according to the Anderson model and were answered by the children's parents. The results were analyzed utilizing Chi-square test logistic regression. The prevalence rate of caries among the pre-school children in selected areas of Chongqing was 55.4%, the decay, missing, filled surface (dmfs) was 6 696, the mean dmfs was 5.2, and the caries filling constituent ratio was 2.3%. A total of 1 173 questionnaires were analyzed. The ratio for seeing a dentist for therapeutic reasons was 6.31% (74/1 173) and for prevalence was 22.93% (269/1 173). The oral health service needs of pre-school children in selected areas of Chongqing are large and the oral health service utilization rate is low. Oral health care processes are arduous; thus, targeted oral prevention policies should be created.
