Objective:1 To explore the interaction between dental fluorosis and caries in middle-aged and elderly people from Taocheng District,Hengshui City,in which is considered as a high fluorine regions in Hebei Province,and analyze the dental fluorosis and caries prevalence in such a region.2 To investigate and analyze the oral hygiene status and behaviors among middle-aged and elderly people in Hengshui City by oral examination and questionnaire,find behavioral risk factors,in order to provide basis for oral health measures in local government policy-making.3 To exam the status of dentition defect and denture restoration,and analyze the factors affecting tooth loss occurrence,and restoration rate in middle-aged and elderly people from Hengshui City,in order to provide theoretical data to taking preventive measures.Methods:103 villagers aged 45-80 years old from Taocheng District,Hengshui,Hebei Province,were given an oral health questionnaire survey and oral examination,in which including 20 edentulous and 1922 permanent teeth in the all.Data on fluorosis,CFI,DMFT,OHI-S and questionnaire were collected and analyzed statistically,to determined the relevant factors that affect villagers oral health status.1 Inspectors:10 dentists from the department of stomatology in the Third Hospital of The Hebei Medical University,were selected as the investigators in this study after strict training.2 Oral exam tool: disposable oral check kit(including dental mirror and probe)was used to exam each person oral status,which were produced by Bazhou Jinsheng science and technology company.3 Questionnaire: According to the purpose of this study,questionnaire basing on the possible relativity among dental fluorosis,caries,oral hygiene,and dentition defect,was made finalized after preliminary test and modification.The questionnaire included as follows: sex,age,education level,oral hygiene habits,the main source of drinking water,etc.4 Investigate items:Referenced to the Third National Oral Health Epidemiology Survey Program[1] and the World Health Organization's Basic Methods of Oral Health Survey(4th ed.)[2],carefully checked,recorded and calculated finally the degree of dental fluorosis,CFI,DMFT,OHI-S,dentition defect,and denture restoration for each surveyed.5 Diagnostic criteria and scoring criteria.5.1 Fluorosis: Methods according to the Dean indexing criteria,were used to define the degree of fluorosis in this study,by scoring tooth surface gloss,discoloration,the degree of damage and the area of the tooth invasion,and then be divided into six groups as : normal,suspicious,slightest,mild,moderate and severe.5.2 Dental caries : The dental caries were examined using the diagnostic criteria in the WH0 "Basic Methods of Oral Health Survey"(4th ed.).5.3 Oral hygiene: The simplified oral hygiene index(OHI-S)was used to evaluate the oral hygiene status in this survey,which including simplified debris index(DI-S)and simplified calculus index(CI-S).5.4 Dentition defect and restoration: According to the Third National Oral Health Epidemiology Survey Program [1] to check and record the population dentition defect,dentition missing and repair situation.6 Statistical processing: The quantitative tables and corresponding databases of case statistics were established,and SPSS 21.0 software package was used for statistical analysis.6.1 According to the Dean index,all the subjects were divided into six groups.The difference of dental caries between the dental fluorosis group and the normal group was analyzed by ?2 test.P <0.05 was considered statistically significant.The difference of dental caries between each group was statistically analyzed by ?2 test,P <0.003 was statistically significant.6.2 According to the number of brushing grouping,the two groups of DI-S and CI-S comparison using t test for data analysis,P <0.05 for the difference was statistically significant.According to whether smoking group,the two groups of DI-S and CI-S comparison using t test for data analysis,P <0.05 for the difference was statistically significant.6.3 Different age group,gender group of tooth loss rate and repair rate of comparison,using ?2 test for data analysis,P <0.05 for the difference was statistically significant.Results:1 The incidence of dental fluorosis The incidence of CFI was 1.45,showed a relatively high level of fluorosis in the high-fluoride area of Hengshui City,Hebei.2 The prevalence of dental caries The dental caries occurrence was 96.39% in this study.3 Oral hygiene A simplified debris index(DI-S)of 6.34,a simplified calculus index(CI-S)of 7.91,showed a poor oral hygiene status among these villager in this area.4 Dentition defect and restoration103 people was surveyed,and tooth loss were found in 74,tooth loss rate was 71.85%,in which 35 cases from 74 got repaired,the restoration rate was47.30%.5 According to the severity,fluorosis was divided into 6 group,:(1)normal group(2)suspicious group(3)very mild group(4)mild group(5)moderate group(6)severe group,each group of permanent teeth caries rate was:(1)38.48%(2)26.48%(3)15.11%(4)11.86(5)50.00%(6)66.67%.It is showed that there were no statistical significant between the third and the fourth groups(P> 0.05).There were statistical significant statistically between the others(P <0.05). 6 According to the brushing times a day,inspected cases were grouped as:(1)<2 times(2)?2 times,The CI-S and DI-S showed statistically significant(P<0.05)between this two groups.7 According to smoking habits,we grouped as:(1)no smoke(2)smok.The CI-S and DI-S values of the two groups were statistically significant(P<0.05).8 The rate of tooth loss and restoration rate were 76.19% and 50.00%respectively in male group,while 68.85% and 45.24% in female group.There were no statistical significance(P> 0.05)between these two groups.9 The rate of tooth loss and repair rate were 63.16% and 33.33%respectively in 45-59 years old group,66.67% and 43.33% in 60-74 years old group,100% and 70% in 75-89 years old.There were statistical significantw between each two group.Both tooth loss ratio and restoration ratio showed a higher in elders.10 Analyzed the type of restoration in this survey,showed as more people in this area got removable denture(26cases,74.29%),and some no-good condition restoration(6 cases,17.14%),fixed denture(3cases,8.57%),no implant restoration(0 cases,0.00%).Conclusion: Local government and medical workers should pay more attention to the middle-aged and elderly people.Strengthening oral health behavior through oral hygiene instruction,early treatment on oral disease,restore dentition timely,improve their life quality.
