Abstract:
Objectives To describe the esthetic acceptance to dental fluorosis in the rural residents of eastern Guangdong Province and to explore whether the Dean's criteria is still suitable for modern society. Methods A survey was conducted in eastern areas of Guangdong Province in 1 237 cases of 9～17 and 35～44 years old rural residents who drank well water containing 0.1～2.5 mg/L of fluoride. Clinical examination and questionnaire investigation were performed to record dental fluorosis and the severity of perceived appearance of their teeth. Results While the study subjects perceived the appearance of their teeth as " no problem", the community fluorosis index (CFI) was 0.5 and prevalence rate of dental fluorosis was 10.1 %. While perceived "a little bit bad" and "bad" and "very bad", the CFI and prevalence rate would be 0.9 and 33.7 %, 1.3 and 75.8 % and 1.7 and 98.2 % respectively. Conclusion The acceptance to the severity was basically in accordance with Dean's criteria. The Dean's criteria about dental fluorosis is still suitable for rural areas of eastern Guangdong Province and therefore it can be used in setting criteria of fluoride concentration in drinking water in these areas.
