Abstract:
OBJECTIVE: To summarize the data about endemic fluorosis, and investigate its prevalence and the effects of prevention and cure, so as to suggest more effective measures for the prevention and cure in the future. DATA SOURCES: A computer-based online search of China National Knowledge Infrastructure (CNKI) and VIP Chinese database was undertaken to identify articles about the distribution, monitoring and effects of prevention and cure of endemic fluorosis published in Chinese from January 1995 to March 2006 by using the keywords of "endemic fluorosis, monitor". STUDY SELECTION: Literatures about endemic fluorosis, including mainly brief introduction, practice in prevention and cure, summary of meeting, etc., the repetitive studies were excluded, and only one of them published the latest was involved. DATA EXTRACTION: Totally 25 relevant literatures were collected, and 18 of them were involved, the others were excluded. DATA SYNTHESIS: The monitoring results showed that until the end of the 2004, 44.51％ of the villages, in the drinking water type disease areas with endemic fluorosis, had executed the low-fluorine treatment of water, and 194 villages had been controlled basically; In the coal pollution type disease areas, 24 villages had been controlled basically,25.42％ of the families had reformed the stoves to prevent the coal pollution. The fluorine in water and air had been obviously declined after the improvement, some place had reached the standard of government.The morbidity rate of dental fluorosis in children of 8 to 12 years old was lower than before; The improving condition was good in most disease areas, and part of them had reached the control line; Meanwhile,the problems also existed that the measures of prevention could not befulfilled completely for the short of money, and the role of decreasing fluorine could not be acted completely because of the ill-management after the changed project.CONCLUSION: After the continuous efforts for tens of years, great progress has been obtained in the prevention and cure of endemic fluorosis,and the prevalence rates of dental fluorosis and skeletal fluorosis have reduced obviously, but many problems also exist at the same time. Therefore,the prevention and cure should be reinforced to restrain its prevalence more effectively.
