RCT on Supragingival Plaque Removing Efficacy of Low-Abrasive Air-Polishing System

Objectives: While air polishing with different highly abrasive powders has been proved efficient for sub- and supragingival application, few studies concerning the quality of supragingival biofilm removal using the low abrasive Erythritol powder (EP) exist. The aim of the present study was to compare the efficacy of supragingival air polishing using EP in comparison with the traditional rubber cup method.
Methods: A sample of 32 young adults, suspending oral hygiene measures for 48 hours, were enrolled in the present double-blind clinical study. Using a split-mouth design, tooth polishing was conducted with either rotating rubber cups and prophylaxis paste or air polishing. While 16 subjects received air polishing in the second and fourth quadrants, for the other half of participants the reverse sequence was applied. Detection of biofilm was assessed using the modified Quigley-Hein index (QHI) before and after treatments. To determine the differences of QHI sum scores achieved prior to polishing, immediately after the polishing procedure and 24 hours later, statistical significance and power output data were assessed using a two-way analysis of variance (ANOVA), followed by a Tukey’s honestly significant difference (HSD) to test multiple pairwise comparisons.
Results: QHI scores corresponded with significantly better performance of air polishing, both immediately (P< .001) and 24 hours later (P < .001) in comparison with the conventional rubber cup method (P < .001).
Conclusions: Supragingival biofilm removal by means of air polishing combined with low abrasive Erythritol seems to be more efficacious than the traditional polishing method.
