AIM
Various chemical solutions have been recommended for denture disinfection; however, the immersion effect on the properties of denture base resin may also have effect on strength of the resin material. The purpose of this study was to compare and evaluate the flexural strength of heat-cure acrylic denture base resin by combination method of denture cleansing and plant extract immersion.
MATERIALS AND METHODS
In this study, ninety specimens of heat-cure acrylic denture base resin material were fabricated with dimensions of 65 mm × 10 mm × 3.3 mm. The specimens were divided into three groups, namely, Group I-III of thirty specimens each and were immersed in distilled water, denture cleanser, and thyme essential oil, respectively. The flexural strength of specimen was evaluated.
RESULTS
Natural plant extract showed better flexural strength than immersed in denture cleanser and control group but statistically was not significant.
CONCLUSION
The study concluded that plant extract, namely, thyme essential oil, showed better flexural strength than combination method and can be used as denture cleanser.
目的
已推荐多种化学溶液用于义齿消毒；然而，浸泡对义齿基托树脂性能的影响可能也会对树脂材料的强度产生作用。本研究的目的是通过义齿清洁与植物提取物浸泡相结合的方法，比较和评估热固化丙烯酸义齿基托树脂的弯曲强度。
材料与方法
在本研究中，制作了90个尺寸为65毫米×10毫米×3.3毫米的热固化丙烯酸义齿基托树脂试件。试件被分为三组，即每组30个试件的第一组至第三组，分别浸泡在蒸馏水中、义齿清洁剂中以及百里香精油中。对试件的弯曲强度进行了评估。
结果
天然植物提取物显示出比浸泡在义齿清洁剂中的试件和对照组更好的弯曲强度，但在统计学上无显著差异。
结论
该研究得出结论，植物提取物，即百里香精油，显示出比组合方法更好的弯曲强度，并且可以用作义齿清洁剂。
