Full-mouth disinfection as a therapeutic protocol for type-2 diabetic subjects with chronic periodontitis: twelve-month clinical outcomes: a randomized controlled clinical trial.

Aim: The aim of this randomized controlled clinical trial was to evaluate the clinical effects of chlorhexidine (CHX) application in a full-mouth disinfection (FMD) protocol in poorly controlled type-2 diabetic subjects with generalized chronic periodontitis.
Material and Methods: Thirty-eight subjects were randomly assigned into FMD group (n=19): full-mouth scaling and root planing (FMSRP) within 24 h + local application of CHX gel + CHX rinses for 60 days or Control group (n = 19): FMSRP within 24 h + local application of placebo gel + placebo rinses for 60 days. Clinical parameters, glycated haemoglobin and fasting plasma glucose were assessed at baseline, 3, 6 and 12 months post-therapies.
Results: All clinical parameters improved significantly at 3, 6 and 12 months post-therapies for both groups (p < 0.05). There were no significant differences between groups for any clinical parameters, and glycemic condition at any time-point (p > 0.05).
Conclusions: The treatments did not differ with respect to clinical parameters, including the primary outcome variable (i.e. changes in clinical attachment level in deep pockets), for up to 12 months post-treatments.
