The present study aimed to evaluate the effect of three various polishing agents on provisional restorative material on immersion in a staining solutions.
The objective of the study is (1) To evaluate the effect of pumice on staining characteristics of provisional restorative material before and after immersion in chlorhexidine. (2) To evaluate the effect of aluminum oxide paste on staining characteristics of provisional restorative material before and after immersion in chlorhexidine. (3) To evaluate the effect of diamond paste on staining characteristics of provisional restorative material before and after immersion in chlorhexidine. (4) To compare and assess the outcome of three polishing agents on staining characteristics of provisional restorative material.
Sixty samples (10 mm × 2 mm) were fabricated of bis-acryl composites (Protemp™ 4) by utilizing a metal mold. The samples were grouped into three groups ( = 20), and various polishing agents were used, including pumice, aluminum oxide paste, and diamond polishing paste. The samples that were not exposed to any polishing agent served as the control group. The samples were kept in a water bath for a day at 37°C and were stained with chlorhexidine mouthwash. The color of all specimens was measured with a spectrophotometer before and after polishing, and color changes (ΔE) were calculated.
By using one-way ANOVA, significant difference was found in mean color change in three polishing materials ( = 4.44, = 0.016). By using Tukey test, statistically significant difference was found among pumice and aluminum oxide paste ( = 0.027), among pumice and diamond paste ( = 0.041) and no significant difference was found among aluminum oxide paste and diamond paste ( = 0.985).
Pumice exhibited less staining which was statistically significant when compared with aluminum oxide paste and diamond paste. Hence, it can be considered the most efficient polishing agent.
本研究旨在评估三种不同的抛光剂对临时修复材料浸泡于染色溶液后的影响。
本研究的目标是:(1)评估浮石对临时修复材料在浸泡于洗必泰前后染色特性的影响。(2)评估氧化铝糊剂对临时修复材料在浸泡于洗必泰前后染色特性的影响。(3)评估金刚石糊剂对临时修复材料在浸泡于洗必泰前后染色特性的影响。(4)比较和评估三种抛光剂对临时修复材料染色特性的效果。
利用金属模具由双丙烯酸复合材料(Protemp™ 4)制作60个样本(10毫米×2毫米)。样本被分为三组(每组n = 20),并使用了不同的抛光剂,包括浮石、氧化铝糊剂和金刚石抛光糊剂。未接触任何抛光剂的样本作为对照组。样本在37°C的水浴中放置一天,并用洗必泰漱口水染色。在抛光前后用分光光度计测量所有样本的颜色,并计算颜色变化(ΔE)。
通过单因素方差分析,发现三种抛光材料的平均颜色变化存在显著差异(F = 4.44,P = 0.016)。通过Tukey检验,发现浮石和氧化铝糊剂之间存在统计学显著差异(P = 0.027),浮石和金刚石糊剂之间存在统计学显著差异(P = 0.041),而氧化铝糊剂和金刚石糊剂之间没有显著差异(P = 0.985)。
与氧化铝糊剂和金刚石糊剂相比,浮石的染色较少,具有统计学显著性。因此,它可被认为是最有效的抛光剂。
