Abstract

PURPOSE

To evaluate the effect of ultrasonic, sonic and rotating-oscillating powered toothbrushing systems on surface roughness and wear of white spot lesions and sound enamel.

METHODS

40 tooth segments obtained from third molar crowns had the enamel surface divided into thirds, one of which was not subjected to toothbrushing. In the other two thirds, sound enamel and enamel with artificially induced white spot lesions were randomly assigned to four groups (n=10) : UT: ultrasonic toothbrush (Emmi-dental); ST1: sonic toothbrush (Colgate ProClinical Omron); ST2: sonic toothbrush (Sonicare Philips); and ROT: rotating-oscillating toothbrush (control) (Oral-B Professional Care Triumph 5000 with SmartGuide). The specimens were analyzed by confocal laser microscopy for surface roughness and wear. Data were analyzed statistically by paired t-tests, Kruskal-Wallis, two-way ANOVA and Tukey's post-test (α= 0.05).

RESULTS

The different powered toothbrushing systems did not cause a significant increase in the surface roughness of sound enamel (P> 0.05). In the ROT group, the roughness of white spot lesion surface increased significantly after toothbrushing and differed from the UT group (P< 0.05). In the ROT group, brushing promoted a significantly greater wear of white spot lesion compared with sound enamel, and this group differed significantly from the ST1 group (P< 0.05). None of the powered toothbrushing systems (ultrasonic, sonic and rotating-oscillating) caused significant alterations on sound dental enamel. However, conventional rotating-oscillating toothbrushing on enamel with white spot lesion increased surface roughness and wear.

CLINICAL SIGNIFICANCE

None of the powered toothbrushing systems (ultrasonic, sonic and rotating-oscillating) tested caused significant alterations on sound dental enamel. However, conventional rotating-oscillating toothbrushing on enamel with white spot lesion increased surface roughness and wear.

摘要

目的

评估超声波、声波和旋转振荡动力牙刷系统对白斑病变和健康牙釉质表面粗糙度及磨损的影响。

方法

从第三磨牙牙冠获取40个牙齿切片，将牙釉质表面分为三等份，其中一份不进行刷牙处理。在另外两份中，将健康牙釉质和人工诱导产生白斑病变的牙釉质随机分为四组（每组n = 10）：UT组：超声波牙刷（Emmi-dental）；ST1组：声波牙刷（高露洁专业临床欧姆龙）；ST2组：声波牙刷（飞利浦声波震动牙刷）；ROT组：旋转振荡牙刷（对照组）（欧乐-B专业护理智控5000）。通过共聚焦激光显微镜分析样本的表面粗糙度和磨损情况。数据采用配对t检验、Kruskal-Wallis检验、双向方差分析和Tukey事后检验进行统计学分析（α = 0.05）。

结果

不同动力牙刷系统未导致健康牙釉质表面粗糙度显著增加（P > 0.05）。在ROT组中，刷牙后白斑病变表面粗糙度显著增加，且与UT组不同（P < 0.05）。在ROT组中，与健康牙釉质相比，刷牙促使白斑病变的磨损显著更大，且该组与ST1组差异显著（P < 0.05）。所有动力牙刷系统（超声波、声波和旋转振荡）均未对健康牙釉质造成显著改变。然而传统旋转振荡牙刷对有白斑病变的牙釉质刷牙会增加表面粗糙度和磨损。
