Background: The aim the study to compare the effects of pre-operative air-powder polishing and rubber-cup prophylaxis on tooth bleaching outcomes.Methods: 23 subjects suffering from discoloration, were enrolled in a randomized controlled split mouth experimental study. Before bleaching, air powder polishing and rubber-cup polishing techniques were applied on either side of the mouth and the tooth bleaching effects assessed immediately after and 7 days.Results: No statistically significant difference was found in for DL, Da, Db, DE and DSGU values between air-powder polishing and rubber-cup groups at immediate and 1 week.The difference between immediate and 1 week measurements is statistically significant in both air-powder polishing and rubber-cup groups, except DL for rubber-cup group, and Da, Db for air-powder polishing group.Conclusions: Within the limitations of the study, it can be concluded that there was no lasting difference in tooth bleaching effects between rubber-cup and air-polishing techniques at immediately after and 1-week post treatment.Trial registration: ClinicalTrial.gov ID: NCT04407910 |
