Case Control Study On Risk Factors Of Periodontitis In CHANGTU County Residents

ObjectiveTo explore the risk factors of periodontal disease in county residents,and to provide scientific basis for the prevention and control of periodontitis.MethodsUsing the case-control study method,120 patients with periodontitis were selected as case group in Stomatology Department of Changtu County Central Hospital in Liaoning province,the age sex and was matched according to the principle of 1:1 pairing,120 healthy medical examiners were selected as control group in the same period,and all the subjects were investigated comprehensively,perform a full oral examination at the same time.Collect and collate the data,use SPSS22.0 statistical analysis software to analyze the data.The differences of education level,economic income,smoking,periodontal disease,regular oral examination,mental stress,diabetes mellitus and iatrogenic factors in the last two months were compared.Conditional logistic regression was used to analyze the risk factors of periodontitis and the combined effect of some risk factors.The correlation between ordered classification variables and periodontitis was analyzed by gamma method.ResultsThe results of single factor analysis showed that 18 factors had an effect on the disease of periodontitis,and the difference was statistically significant(P <0.05).The results of correlation analysis showed that the level of education,smoking index,the number of brushing times of brushing time,the type of drinking water and the degree of periodontitis were correlated(P <0.05).After the condition logistic analysis,the independent variable: The residence is rural,smoking,the existence of bad prosthesis,the immediate family has periodontitis,understands the knowledge of periodontitis and often eats crude fiber food into the regression model,the regression coefficient is statistically significant(P <0.05).Its or 95% confidence intervals are 2.149(1.096,5.339),3.262(1.240,8.581),3.336(1.083,10.278),18.930(3.788,95.854),0.045(0.019,0.106),4.529(1.364,15.044),0.166(0.055,0.501).By joint Action analysis,smoking and the presence of undesirable prosthetics and smoking and chewing hard objects in the occurrence of periodontitis in a synergistic role(P <0.05).Conclusion1?The case Group Soft scale index,dental stone Index,plaque Index,gingival index,probe depth and adhesion loss were higher than the control group.2,The place of residence for rural areas,immediate family members suffering from periodontitis,smoking,the presence of poor oral prosthesis,chewing hard is a risk factor for the onset of periodontitis.3,Understand the knowledge of periodontitis and frequent intake of crude fiber food for the pathogenesis of periodontitis protection factors.4,Education level,smoking index,income,brushing time,brushing times and drinking water type and the degree of periodontitis have a clear correlation,in which the severity of periodontitis with the reduction of education level,smoking index increases;decreases with income,brushing times,brushing time and drinking water quality.5,The presence of poor oral prosthesis at the same time there are smoking habits and chewing hard habits and smoking habits will promote the occurrence and exacerbation of periodontitis.
