Professional mechanical biofilm reduction is a cornerstone of supportive periodontal therapy (SPT) for periodontitis. This study evaluated the effectiveness of two methods—rotating polishing rubber cups (RCs) and air-polishing (AP) devices—in periodontitis patients. Including 430 patients with average age 60.7 years, the study found that both methods were similarly effective in stabilizing or improving periodontal sites with PPD ≥ 5 mm. However, AP showed greater advantage in preventing PPD ≥ 5 mm deterioration in molars with furcation involvement, while RC interventions were more effective in preventing deterioration in these sites. The study highlights that both methods are effective in maintaining periodontal stability, though RC may be more favorable in specific cases. The results emphasize the importance of individualized interventions, particularly in complex root anatomy, and suggest that repeated subgingival AP application is clinically safe and effective. The study was conducted over a 5-year period, with SPT sessions once a year, and involved a comprehensive analysis of clinical parameters like PPD, furcation involvement, BOP, and dental status. All data were collected by experienced specialists following institutional guidelines.
