Abstract

Background: Recently, the use of whitening dentifrice has increased among patients. However, these products might increase the surface roughness of composite restorations and make them more susceptible to discoloration and plaque accumulation. This study aimed to compare the effects of two charcoal-based dentifrices and other whitening dentifrices with different mechanisms of action on the surface roughness of an aged resin composite.

Methods: Forty-five composite specimens were made (2 × 7mm) and their initial surface roughness was obtained using a Profilometer. The specimens were subjected to the Accelerated Artificial Aging (AAA) process for 300 hours. Then, the surface roughness of the specimens was reevaluated using the Profilometer. The specimens were randomly divided into 5 groups (N.=9), namely Control (Gc), Bencer (Gb; Sormeh Company, Tehran, Iran), Perfect White Black (Gp), Colgate Total Whitening (Gt), and Colgate Optic White (Go) (Colgate-Palmolive Company, New York, NY, USA). The specimens were brushed for 14 minutes with respective dentifrices. In the Gc group, the specimens were only brushed with distilled water. The surface roughness of the specimens was measured again. The data were analyzed using repeated measure ANOVA at a significance level of 0.05.

Results: There was no significant difference in surface roughness parameters (Ra, Rq, Rz) between the groups, but in each group, the roughness parameters decreased after the aging procedure and increased after brushing significantly except for Rz parameter in Gb group which increased after aging and decreased after brushing.

Conclusions: None of the whitening dentifrices used in the present study had an adverse effect on the surface roughness of an aged composite resin.

炭基牙剂对老化树脂复合材料表面粗糙度的影响。

背景:近年来，美白牙膏的使用在患者中有所增加。然而，这些产品可能会增加复合修复体的表面粗糙度，使其更容易变色和斑块堆积。本研究旨在比较两种具有不同作用机制的炭基牙剂和其他美白牙剂对老化树脂复合材料表面粗糙度的影响。方法:制作45个2 × 7mm的复合材料试样，用Profilometer测量其初始表面粗糙度。试样进行加速人工老化(AAA) 300小时。然后，使用Profilometer重新评估样品的表面粗糙度。将标本随机分为5组(n =9)，分别为Control (Gc)、Bencer (Gb);Sormeh公司，德黑兰，伊朗)，完美白黑(Gp)，高露洁全面美白(Gt)，高露洁光学白(Go)(高露洁棕榄公司，纽约，纽约，美国)。分别用牙刷刷刷14分钟。Gc组仅用蒸馏水刷洗。再次测量试样的表面粗糙度。数据分析采用重复测量方差分析，显著性水平为0.05。结果:各组表面粗糙度参数Ra、Rq、Rz无显著差异，但除Gb组表面粗糙度参数Ra、Rq、Rz老化后显著降低、刷刷后显著升高外，其余各组表面粗糙度参数Ra、Rq、Rz老化后显著升高、刷刷后显著降低。结论:本研究中使用的美白牙膏均未对老化复合树脂的表面粗糙度产生不利影响。
