Introduction The aim of this study was to evaluate the activity of an ethanolic extract of Aloe vera on and Materials and methods A total of 42 heat-cured acrylic resin specimens were made and divided into three groups according to the disinfection method: (1) Corega disinfectant tablets; (2) ethanol extract of Aloe vera; and (3) distilled water (as a control group). Fresh Aloe vera whole leaves were washed with distilled water, chopped into small pieces, air-dried, and ground into powder. The powder was extracted with 95% ethanol. The acrylic specimens were contaminated with and , and then the specimens were immersed in study solutions for three minutes. The viable colonies were counted using the colony-forming units (CFU) method. Results The results showed a decrease in the number of CFU for denture tablets and Aloe vera ethanoic extract groups compared to the negative control group. There were no significant statistical differences between the denture tablet group and the Aloe vera ethanolic extract group (P < 0.05). Aloe vera ethanolic extract groups significantly decreased the number of CFU compared to the negative control group and less compared to the denture tablet, where significant statistical differences were found between the tablet group and the Aloe vera ethanolic extract group. Conclusions Within the limitations of this study, it was concluded that Aloe vera extract was effective against and when acrylic resin specimens were immersed for three minutes.
引言 本研究的目的是评估库拉索芦荟乙醇提取物对[具体细菌名称1]和[具体细菌名称2]的活性。材料与方法 共制作了42个热固化丙烯酸树脂标本，并根据消毒方法分为三组：(1) 科瑞加消毒片；(2) 库拉索芦荟乙醇提取物；(3) 蒸馏水（作为对照组）。将新鲜的库拉索芦荟全叶用蒸馏水冲洗，切成小块，风干，磨成粉末。用95%乙醇提取该粉末。将丙烯酸标本用[具体细菌名称1]和[具体细菌名称2]污染，然后将标本浸入研究溶液中三分钟。使用菌落形成单位（CFU）法计算活菌菌落数。结果 结果显示，与阴性对照组相比，假牙片组和库拉索芦荟乙醇提取物组的CFU数量减少。假牙片组和库拉索芦荟乙醇提取物组之间无显著统计学差异（P < 0.05）。与阴性对照组相比，库拉索芦荟乙醇提取物组显著降低了CFU数量，与假牙片组相比则降低较少，在片剂组和库拉索芦荟乙醇提取物组之间发现了显著的统计学差异。结论 在本研究的局限性范围内，得出结论：当丙烯酸树脂标本浸泡三分钟时，库拉索芦荟提取物对[具体细菌名称1]和[具体细菌名称2]有效。
