title: Comparison of glycated hemoglobin levels in individuals without diabetes and with and without periodontitis before and after non-surgical periodontal therapy.
abstract: BACKGROUND
  Only a few studies have examined the association between periodontitis and glycated hemoglobin (HbA1c) levels in individuals without diabetes. The aim of this study is to compare HbA1c levels in individuals without diabetes and with and without periodontitis before and after non-surgical periodontal therapy.
  
  
  METHODS
  This comparative study was done on individuals without diabetes who were 35 to 65 years old. Group A consisted of 30 individuals without periodontitis, and group B consisted of 30 individuals with periodontitis. Body mass indices and clinical parameters, including oral hygiene index-simplified (OHI-S) score, gingival index (GI), probing depth (PD), clinical attachment level (CAL), and HbA1c level, of all participants were recorded. All participants received non-surgical periodontal therapy (scaling and root planing). After 3 months, all participants were reexamined, and clinical parameters and HbA1c levels were evaluated and compared to baseline values.
  
  
  RESULTS
  There were significant differences between group A and group B in regard to baseline OHI-S, GI, PD, and HbA1c (P <0.05). There was no clinical attachment loss in group A, either at baseline or after 3 months. At the end of 3 months, group B showed improvement in all clinical parameters (P <0.05) and their HbA1c levels also significantly decreased (P <0.05), although the values never reached those of group A.
  
  
  CONCLUSIONS
  The HbA1c levels of individuals without diabetes and with periodontitis (group B) were significantly reduced 3 months after non-surgical periodontal therapy, although they never reached the same levels as those of the individuals without diabetes or periodontitis (group A).
