Effect of periodontal treatment on glycosylated hemoglobin levels in elderly patients with periodontal disease and type 2 diabetes

Background Periodontal disease is closely related to type 2 diabetes and is an important complication of diabetes.This study aimed to investigate the effect of periodontal treatment on levels of blood glucose(Glu)and glycosylatedhemoglobin(HbA1 c)among elderly patients with type 2 diabetes and periodontal disease.Methods A total of 107 elderly patients with type 2 diabetes and periodontal disease were selected and divided into twogroups according to their HbA1c levels.Group A was a well-controlled diabetic group and group B was uncontrolled.Their probing depth(PD),attachment loss(AL),the value of Glu and HbA1c were analyzed before periodontal treatmentand 4 months later.Results There was a significant difference in periodontal condition between groups A and B(P<0.01).The periodontalcondition for both groups was significantly(P<0.01)improved after periodontal therapy.The effect of treatment in group Awas more pronounced than group B,and the difference was significant(P<0.01).After the periodontal treatment,Gluand HbA1c were reduced significantly in both groups(P<0.05).Conclusions Periodontal condition is related to the control of Glu level among elderly patients with type 2 diabetes andperiodontal disease.Periodontal treatment can effectively reduce the level of Glu and HbA1c as well as improve theperiodontal condition in elderly type-2 diabetes patients with penodontal disease.
