The purpose of the current study was to evaluate the impact of three different denture cleansers on the strength and surface roughness of heat-polymerizing resin.
A total of 120 resin discs (10 mm in diameter and 2 mm thick) were created using a stainless steel mold for surface roughness testing and flexural strength testing (in accordance with the American Dental Association (ADA) Specification No.12). Samples were divided into one of three groups (40 samples in each group): group I: Clanden, group II: Clinsodent, group III: Fittydent. Samples were immersed in denture-cleansing solutions for 30 minutes every day, and this process was repeated over a period of 15 days. Samples were stored in distilled water at room temperature in between the immersions. A surface analyzer was utilized to compare the surface roughness of each sample before and after immersion treatments. For recording flexural strength, each sample was subjected to three-point bending test by mounting samples on Universal testing machine. Comparing mean values between groups using one-way ANOVA and the Tukeys honest significant difference (HSD) test. A significance level of 0.05 was used for all statistical calculations Results: After 15 days, the maximum change of mean surface roughness of heat-polymerizing resin was found in Clanden denture cleanser group (2.64 ± 0.12) followed by Clinsodent group (2.26 ± 0.09) and Fittydent group (1.92 ± 0.06). After 15 days, the maximum change of mean flexural strength changes of heat-polymerizing resin was found in Clanden denture cleanser group (94.78 ± 0.14), followed by Fittydent group (98.64 ± 0.03) and Clinsodent group (99.26 ± 0.21).
Within the limitation, the current study concluded that changes were observed in surface roughness and flexural strength of all heat-polymerizing resin samples after immersion in all three denture cleansers; but least surface roughness and flexural strength changes were observed with the Fittydent cleanser group and Clinsodent group, respectively.
Cleaning dentures is crucial for maintaining both the prosthesis and oral health; therefore, it is necessary to select a cleanser that is effective without negatively affecting the base resin's qualities over time.
本研究旨在评估三种不同假牙清洁剂对热聚合树脂强度和表面粗糙度的影响。
使用不锈钢模具制作了 120 个直径为 10 毫米、厚度为 2 毫米的树脂圆盘,用于表面粗糙度测试和弯曲强度测试(符合美国牙科协会(ADA)规范第 12 号)。样本分为三组(每组 40 个样本):I 组:Clanden、II 组:Clinsodent、III 组:Fittydent。每天将样本浸入假牙清洁剂中 30 分钟,此过程重复 15 天。在浸入之间,将样本储存在室温下的蒸馏水中。使用表面分析仪比较浸泡处理前后每个样本的表面粗糙度。为了记录弯曲强度,将每个样本安装在万能试验机上进行三点弯曲试验。使用单向方差分析和 Tukeys 诚实显著差异(HSD)检验比较组间平均值。所有统计计算均使用 0.05 的显著性水平。
15 天后,在 Clanden 假牙清洁剂组中发现热聚合树脂的最大表面粗糙度平均变化值最高(2.64±0.12),其次是 Clinsodent 组(2.26±0.09)和 Fittydent 组(1.92±0.06)。15 天后,在 Clanden 假牙清洁剂组中发现热聚合树脂的最大平均弯曲强度变化值最高(94.78±0.14),其次是 Fittydent 组(98.64±0.03)和 Clinsodent 组(99.26±0.21)。
在限制范围内,本研究得出结论,在所有三种假牙清洁剂中浸泡后,所有热聚合树脂样本的表面粗糙度和弯曲强度都发生了变化;但是在 Fittydent 清洁剂组和 Clinsodent 组中观察到的表面粗糙度和弯曲强度变化最小。
清洁假牙对于维护义齿和口腔健康至关重要;因此,有必要选择一种清洁剂,这种清洁剂在随着时间的推移不会对基础树脂的质量产生负面影响的情况下是有效的。
