HbA1c changes in patients with diabetes following periodontal therapy

Abstract

Purpose This retrospective cohort study aimed to assess the effect of nonsurgical periodontal therapy on glycated hemoglobin (HbA1c) levels in patients with both type 2 diabetes and chronic periodontitis. Methods The intervention cohort (IC) comprised 133 patients with type 2 diabetes who received nonsurgical periodontal treatment, while the matching cohort (MC) included 4787 patients with type 2 diabetes who visited the Department of Endocrinology and Metabolism of Asan Medical Center. The patients in each cohort were divided into 3 groups according to their baseline HbA1c level: subgroup 1, HbA1c <7%; subgroup 2, 7%≤ HbA1c <9%; and subgroup 3, HbA1c ≥9%. Changes in HbA1c levels from baseline to 6 and 12 months were analyzed. In addition, the association between changes in HbA1c levels and the number of periodontal maintenance visits was investigated. Results There were no statistically significant changes in HbA1c levels in the IC and MC or their subgroups when evaluated with repeated-measures analysis of variance. However, the IC showed maintenance of baseline HbA1c levels, while the MC had a trend for HbA1c levels to steadily increase as shown by pairwise comparisons (baseline to 6 months and baseline to 12 months). IC subgroup 1 also maintained steady HbA1c levels from 6 months to 12 months, whereas MC subgroup 1 presented a steady increase during the same period. The number of periodontal maintenance visits had no association with changes in HbA1c levels during the 1-year study duration. Conclusions For patients with both type 2 diabetes and periodontitis, nonsurgical periodontal treatment and periodontal maintenance may help to control HbA1c levels.

Improvement of oral health knowledge and behavior of diabetic patients: An interventional study by using the social media

“…It is believed that reduction in HbA1c level is multifactorial, and depends on several factors such as exercise, nutrition, and therapeutic interventions (46,47). However, some others reported a signi cant reduction in HbA1c level, which can be due to non-surgical periodontal therapy by scaling and root planing and longer followups (48,49).…”

Prevalence and Associated Factors for Periodontal Disease among Type I and II Diabetes Mellitus Patients: A Cross-Sectional Study

“…For patients with both type II diabetes and periodontitis, nonsurgical periodontal treatment and periodontal maintenance may help to control HbA1c levels [ 28 ]. A dental office that treats patients with periodontitis is a suitable location for screening for diabetes by a simple finger stick and validated HbA1c dry spot analysis [ 29 ].…”

Preliminary evaluation of the impact of periodontal treatment on markers of glycaemic control in dogs with diabetes mellitus: A prospective, clinical case series

“…40 Severe PD significantly increases the risk of poor diabetic control 41 and its complications, including proteinuria, renal insufficiency 42 and cardiorenal mortality. 43 Correspondingly, a plethora of studies demonstrate a propitious effect of PT on glycaemic control, 10,[44][45][46] which translates to clinically meaningful reductions in HbA1c levels. In dogs, however, information is scarce.…”
