OBJECTIVES

While air polishing with abrasive powders has been proved efficient for sub- and supragingival application, only few studies concerning the quality of supragingival biofilm removal using the low-abrasive erythritol powder (EP) exist. The aim of the present randomized controlled trial was to clinically compare the efficacy of supragingival air polishing using EP in comparison with the rubber cup method, and to juxtapose the corresponding biofilm regrowth rates.

METHOD AND MATERIALS

Thirty-two young adults, suspending oral hygiene for 48 hours, were enrolled in the present double-blind short-term investigation. Using a split-mouth design, tooth polishing was conducted by means of either air polishing or rubber cups with prophylaxis paste (control). While 16 participants received air polishing in the second and fourth quadrants (and rubber cup prophylaxis in the first and third ones), the reverse sequence was applied with the remaining 16 subjects. Biofilms were assessed using the modified Quigley-Hein index (QHI), and QHI sum scores achieved both prior to and immediately after the polishing procedure, as well as 24 hours later, were assessed using a two-way analysis of variance (ANOVA), followed by Tukey's HSD to test multiple pairwise comparisons.

RESULTS

Both methods revealed a significant reduction of QHI scores (P < .001). Compared to the rubber cup method, air polishing resulted in significantly lower scores, both after tooth cleaning and after 24 hours (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, and should improve oral health care.
