It is known that the use of mouthwashes and toothbrushing can affect some restorative dental materials. The purpose of this laboratory study was to investigate the effect of four commercially available mouthwashes on the surface roughness of a number of resin modified glass-ionomer restorative materials when used with and without tooth brushing.
Specimens of the restorative materials in the study (Vitremer, Compoglass and Dyract) were prepared. Half of the specimens were only exposed to a mouthwash (Plax, Macleans, Listerine, Corsodyl or deionised water as control). The remaining specimens were exposed to one of the mouthwashes in conjunction with tooth brushing. The initial surface roughness and the subsequent changes in surface roughness were assessed by scanning electron microscopy (SEM) and profilometry. The assessment times were: baseline, 4, 12 and 24 weeks.
Initial SEM observations of the surface morphology of the specimens revealed a rougher surface for Vitremer in comparison to the other two materials. Assessments at increasing time intervals showed that specimens exposed to a mouthwash only appeared to become rougher. The appearance of specimens exposed to mouthwash and brushing seemed to become even rougher with increasing time. The results of the profilometric assessment showed that at 24 weeks, specimens exposed to mouthwash only, had an overall increase in the surface roughness values for all three materials investigated. The differences between groups allocated to different mouthwashes were not however statistically significant (P>0.05). Exposure to mouthwash and toothbrushing over the same time period resulted in an increase in roughness values in all groups. The differences between mouthwash groups were not statistically significant at this stage (P>0.05).
Exposure of the materials investigated to the mouthwashes included in the study had adverse effects on surface roughness. The adverse effects were more pronounced with tooth brushing.
已知使用漱口水和刷牙会影响某些牙科修复材料。本实验室研究的目的是调查四种市售漱口水在使用和不使用刷牙的情况下,对多种树脂改性玻璃离子修复材料表面粗糙度的影响。
制备了研究中修复材料(Vitremer、Compoglass和Dyract)的样本。一半样本仅暴露于漱口水(Plax、Macleans、Listerine、Corsodyl或去离子水作为对照)。其余样本则在刷牙的同时暴露于其中一种漱口水。通过扫描电子显微镜(SEM)和轮廓仪评估初始表面粗糙度以及随后表面粗糙度的变化。评估时间为:基线、4周、12周和24周。
对样本表面形态的初始SEM观察显示,与其他两种材料相比,Vitremer的表面更粗糙。随着时间间隔增加进行的评估表明,仅暴露于漱口水的样本似乎变得更粗糙。暴露于漱口水和刷牙的样本随着时间推移似乎变得更粗糙。轮廓仪评估结果表明,在24周时,仅暴露于漱口水的样本,所研究的所有三种材料的表面粗糙度值总体上有所增加。然而,分配到不同漱口水组之间的差异无统计学意义(P>0.05)。在同一时间段内暴露于漱口水和刷牙导致所有组的粗糙度值增加。此时漱口水组之间的差异无统计学意义(P>0.05)。
研究中所调查的材料暴露于漱口水会对表面粗糙度产生不利影响。刷牙时这种不利影响更为明显。
