ABSTRACT

Objective:To study risk factors of the old subjects with severe periodontitis.Methods:1 60 cases of patients aged 61 ~81 years with severe periodontitis were included in the case group and other 200 cases of age matched individuals without periodontitis were included in the control group.The related risk factors for senile severe periodontitis were analyzed by oral and periodental exami-nation and questionaire survey.Results:Smoking (OR =3.1 601 ,95% CI1 .051 -1 .31 0),diabetes mellitus(OR =2.1 42,95%CI1 .621 -5.91 2),bad prosthesis(OR =1 .989,95% CI1 .21 8 -4.298),merging root bifurcation lesions (OR =3.282,95%CI1 .01 9 -2.296)and the combination of systemic disease (OR =2.1 96,95% CI1 .51 6 -2.61 9)factors were closely related to the pathogenesis of elderly severe periodontitis,and were the independent risk factors.Conclusion:Smoking,diabetes mellitus,bad prosthesis,root bifurcation lesions and the combining systemic disease are main risk factors of senile severe periodontitis diseases.
