Abstract

Objectives: Over the years, professional dental prophylaxis has involved the use of rubber-cup, bristle brush, and abrasive paste for coronal polishing. Although air polishing is an excellent alternative for removal of tooth stain and dental plaque, very few studies have compared their efficacy in vivo. The present study attempts to evaluate and compare the efficacy of air polishing (test) alone versus rubber-cup polishing (control).

Materials and methods: A total of 35 individuals having generalized mild to moderate gingivitis were enrolled as the study population after obtaining their informed consent. Before commencement of the study, all subjects underwent scaling to remove calculus deposits (if any), following which the ipsilateral quadrant of the patient's mouth was randomly assigned as the test side and the contralateral quadrant of the same arch was assigned as the control side for polishing procedures. Time employed for both methods of polishing was held constant at 5 min for each technique. Subjects were assessed before and immediately after polishing and again after 15 days following treatment, for plaque and gingival status along with gingival bleeding.

Results: Overall, the results of the intra-group comparison of both the polishing procedure sites indicated similar but significant plaque and gingival status changes, whereas the inter-group comparison showed no significant difference between the efficacies of both the groups.

Conclusions: Air polishing and the rubber-cup, bristle brush with paste polishing demonstrated equivalent efficacy regarding removal of supragingival plaque and in reducing gingival inflammation.

Keywords: Dental polishing; dental prophylaxis; gingivitis; plaque.
