Abstract

This clinical study aimed to compare the effects of preoperative air-powder polishing and rubber-cup prophylaxis on tooth bleaching. Twenty-three patients with tooth discoloration were enrolled in this randomized controlled split-mouth experimental study. Before bleaching, air-powder polishing (APP) and rubber-cup polishing (RCP) techniques were applied on either side of the mouth. A 40% hydrogen peroxide bleaching agent was applied twice for 15min for the in-office bleaching treatment. The tooth bleaching effects were assessed immediately and 1week after bleaching. There were no significant differences between the prophylaxis groups with respect to all color parameters (ΔL, Δa, Δb, ΔSGU, and ΔE00) immediately after bleaching (p > 0.05). At 1-week assessment period, there were no significant differences between the prophylaxis groups with respect to all color parameters (p > 0.05), except ΔE00 (p < 0.05). Immediately after the bleaching treatment, the two prophylactic techniques produced similar efficacy. One week after the bleaching treatment, the APP technique produced higher levels of color changes. APP prophylaxis before bleaching treatment may reduce the application time and the number of sessions to achieve the desired color. ClinicalTrial.gov ID: NCT04407910.

There was no statistically significant differences between the ARP and rubber-cup polishing (RCP) groups for ∆Eab and ∆SGU means, while ∆E00 mean difference was statistically different at 1 week period (Table 4). When the prophylaxis groups were compared with each other for all color parameters, there was no significant difference during immediate and 1-week assessment periods
This study evaluated the influence of dental prophylaxis technique prior tooth bleaching in the change of color

The aim the study to compare the effects of pre-operative air-powder polishing and rubber-cup prophylaxis on tooth bleaching. A 40% hydrogen peroxide bleaching agent applied two 15-minute applications for in-office bleaching. Results: There were no significant differences between prophylaxis groups with respect to all color parameters (∆ L, ∆a, ∆b, ∆SGU, ∆Eab, ∆ E00) at immediate period (p>0,05). At 1 week assessment period there were no significant differences between prophylaxis groups with respect to all color parameters (p>0,05) except delta E00 (p
