Abstract

OBJECTIVES

The purpose of this study was to evaluate the efficiency of bleaching after combining ozone and 38% H2O2 in comparison to the sole use of 38% H2O2.

METHODS

Consecutive 26 participants (13 males and 13 females) were recruited into this study. They were randomly allocated into 2 groups (n=13 for each group). In group 1 (test group); the participants' upper anterior teeth were treated with 38% H2O2 for 20min then the teeth were exposed to ozone for 60s (healOzone(®) X4, KaVo Dental, Biberach, Germany). In group 2 (controls); the upper anterior teeth were treated with 20min of 38% H2O2 only. The shade of teeth was evaluated by recording the L* a* b* values and Vita Classic shades at study baseline and after bleaching in both groups. The statistically significant changes were set at P≤0.05.

RESULTS

Tooth sensitivity and teeth shades were comparable between groups at study baseline (p>0.05). Controls reported more tooth sensitivity following bleaching (p<0.001). Teeth achieved better Vita shades, higher L* values (lighter shades), and lower a* and b* values (lighter shades) after bleaching in both groups (P≤0.05). However, teeth bleached with H2O2 and ozone achieved better Vita shades, higher L* values and lower a* values (lighter shades) than those bleached with H2O2 alone (p<0.001). Changes in b* values were not significantly different between groups.

CONCLUSIONS

Bleaching with 38% H2O2 for 20min followed by 60s of ozone application would result in teeth with lighter shades than bleaching with 38% H2O2 alone.

摘要

目的

本研究旨在评估与单独使用 38% H2O2 相比，将臭氧与 38% H2O2 结合使用进行漂白的效果。

方法

本研究共招募了 26 名连续患者（男性 13 名，女性 13 名），并将他们随机分配到 2 个组（每组 13 名）。在第 1 组（实验组）中，患者的上前牙用 38% H2O2 处理 20 分钟，然后用臭氧处理 60 秒（德国 KaVo Dental 的 healOzone(®) X4）。在第 2 组（对照组）中，仅用 20 分钟的 38% H2O2 处理上前牙。在两组中，均在研究基线和漂白后记录 L*、a*、b*值和 Vita 经典比色。设置统计学显著变化为 P≤0.05。

结果

在研究基线时，两组的牙齿敏感和牙齿颜色相似（p>0.05）。对照组在漂白后报告更多的牙齿敏感（p<0.001）。两组牙齿在漂白后都获得了更好的 Vita 比色、更高的 L值（更浅的色调）和更低的 a和 b值（更浅的色调）（P≤0.05）。然而，用 H2O2 和臭氧漂白的牙齿比单独用 H2O2 漂白的牙齿获得了更好的 Vita 比色、更高的 L值和更低的 a值（更浅的色调）（p<0.001）。两组间 b值的变化无显著差异。
