Randomized Trial to Test a Chemo-Mechanical Antiplaque Regimen as Adjunct to Periodontal Therapy

The control of dental biofilm regrowth after nonsurgical periodontal therapy is associated with better clinical outcomes. However, many patients have difficulty achieving optimal plaque control. Subjects with diabetes, in which immune and wound-healing responses are typically impaired, may benefit f...

Shrnutí:The control of dental biofilm regrowth after nonsurgical periodontal therapy is associated with better clinical outcomes. However, many patients have difficulty achieving optimal plaque control. Subjects with diabetes, in which immune and wound-healing responses are typically impaired, may benefit from intensive antiplaque control regimens after scaling and root planing (SRP). This study aimed to evaluate the effects of an intensive, at-home, chemical, and mechanical antiplaque regimen as an adjunct to SRP for the treatment of moderate to severe periodontitis. A secondary objective was to compare responses in subjects with type 2 diabetes and nondiabetics. This was a 6-mo, single-center, parallel-group, randomized trial. The test group received SRP and oral hygiene instructions, and subjects were instructed to use a 0.12% chlorhexidine gluconate mouthrinse twice a day for 3 mo and utilize rubber interproximal bristle cleaners twice a day for 6 mo. The control group received SRP and oral hygiene instructions. The main outcome was change in mean probing depth (PD) from baseline to 6 mo. Secondary outcomes included change in sites with deep PDs, mean clinical attachment level, bleeding on probing, plaque index, hemoglobin A1C, fasting blood glucose, C-reactive protein, and taste assessment. This study was registered at ClinicalTrials.gov as NCT04830969. In total, 114 subjects were randomized to either treatment. Eighty-six subjects completed the trial with no missing visits. Neither an intention-to-treat nor a per-protocol analysis showed statistically significant differences between treatment groups in mean PD at 6 mo. In a subgroup analysis, subjects with diabetes in the test group showed a statistically significant greater reduction in mean PD at 6 mo when compared to subjects with diabetes receiving the control treatment (Δ = 0.15, = 0.04), while there were no differences within nondiabetics (Δ = 0.02, = 0.75). Outcomes in subjects with diabetes may be improved by chemo-mechanical antiplaque measures after nonsurgical periodontal therapy.
