Abstract

Transverse strength is the resistance of the denture base to the load, pressure, and thrust when the mouth is functioning and is also influenced by some chemicalsas solvents, such as those contained in food, beverages and denture cleaning materials. This study was intended to determine the transverse strength of heat polymerized acrylic resin (HPAR) in a solution of basil leaf extract. The experimental design of this study was a post-test only control group with a sample size of 24 which was divided into 4 groups. Samples were soaked in sterile distilled water for 24 hours and then immersed in a solution of 25%, 50%, and 75% basil leaf extract, as well as sterile aquadest; for 8 days. The transverse strength was measured using a universal testing machine. Data were analyzed by one-way Anova and tested with least significant difference (p<0.05). The results showed that the transverse strength of the HPAR plate immersed in basil leaf extract decreased at a concentration of 25% and 50% and the lowest was at a concentration of 75%. It was concluded that basil leaf extract could decrease the transverse strength of HPAR.

罗勒叶提取物浸渍热聚合丙烯酸树脂板的横向强度

横向强度是指义齿基托在口腔工作时对负荷、压力和推力的抵抗能力，也受一些化学物质和溶剂的影响，如食品、饮料和义齿清洁材料中所含的化学物质和溶剂。本研究旨在测定热聚合丙烯酸树脂(HPAR)在罗勒叶提取物溶液中的横向强度。本研究的实验设计为仅设后测对照组，样本量24人，分为4组。样品在无菌蒸馏水中浸泡24小时，然后分别浸入25%、50%、75%罗勒叶提取物的溶液和无菌清液中;8天。横向强度采用万能试验机测量。资料采用单因素方差分析，差异无统计学意义(p<0.05)。结果表明，罗勒叶提取物浓度为25%和50%时，HPAR板的横向强度降低，浓度为75%时最低;结果表明，罗勒叶提取物可降低HPAR的横向强度。
