Objectives: To describe retained deciduous teeth condition among residents in Fujian Province, analyze its distribution pattern, and provide reference for both its clinical treatment and epidemiological situation. Methods: Multi-stage, stratified sampling was used to randomly select 8528 persons from 4 age groups. Results: The prevalence of retained deciduous teeth in 15~, 18~, 35~44, 65~74 year-olds are 1.41%, 1.31%, 0.38%, 0, respectively. The oldest person is 36 years old. There are at most 4 retained deciduous teeth in one single person. And condition is mostly seen at first deciduous molar and maxillary deciduous cuspid. Conclusions: For those retained deciduous teeth with no permanent successors, they can be retained as far as possible. If there is permanent embryo underside, they can be removed and guidance is made for the eruption. In future oral health epidemiological survey, retained deciduous teeth should be considered.
