Evaluation of Subantimicrobial Dose Doxycycline as an Adjunct to Scaling and Root Planing in Chronic Periodontitis Patients with Diabetes: A Randomized, Placebo-Controlled Clinical Trial

Abstract Aim Diabetic patients have more severe periodontal destruction, but periodontal therapy can improve metabolic control. Recently, interest has focused on the use of subantimicrobial dose doxycycline (SDD) as a treatment paradigm. Therefore, this study was undertaken to evaluate clinical efficacy of SDD with scaling and root planning (SRP) in chronic periodontitis patients with diabetes. Methods and Materials Twenty chronic periodontitis patients with diabetes mellitus were randomly allocated to either a test and a control group. Clinical measurements were recorded at baseline and at six months for probing pocket depth (PPD), clinical attachment level (CAL), and gingival recession (GR). After SRP, patients in the test group were instructed to take SDD 20-mg capsules twice a day while patients in the control group took a placebo twice a day. Both groups were on this regimen for a six-month period. Results A greater reduction in mean PPD was demonstrated in patients in the test group compared to the control group. The mean CAL increase observed in the test group was significantly greater (0.67 mm) than that in the control group. Conclusion It can be concluded that SRP, in conjunction with the SDD therapy described, is more effective then SRP alone in terms of CAL gain and PPD reduction in diabetic patients with severe periodontal disease. Clinical Significance Given the widespread prevalence of both chronic periodontitis and diabetes, the proposed treatment approach will prove to be of great value and contribute significantly to the overall health of the patients.
