This work aimed to determine the effect of adding chitosan and acrylic acid to acrylic resin denture base on the porosity of the material and the growth of .
This study is an experimental laboratory research. Samples were divided into the following three groups ( = 10): group 1 was the control group, group 2 was the acrylic resin mixture with 1% chitosan and acrylate acid, and group 3 was the acrylic resin mixture with 2% chitosan and acrylate acid. growth was tested using the dilution method, and porosity was examined using an optical microscope. Data were calculated by one-way analysis of variance ( < 0.05) and correlation analysis.
The acrylic resin added with 2% chitosan and acrylic acid showed pores with an almost spherical shape and the smallest size. Significant difference ( < 0.05) was observed among all the groups. A positive and extremely strong correlation was found between porosity and growth.
Chitosan and acrylic acid at 1 and 2% concentrations can be added to acrylic resin to minimize the porosity of the denture base and reduce the growth of . A less porous denture is associated with a low growth rate.
本研究旨在确定向丙烯酸树脂义齿基托中添加壳聚糖和丙烯酸对材料孔隙率及[未提及的某种微生物]生长的影响。
本研究为实验性实验室研究。样本分为以下三组（每组n = 10）：第1组为对照组，第2组为含1%壳聚糖和丙烯酸的丙烯酸树脂混合物，第3组为含2%壳聚糖和丙烯酸的丙烯酸树脂混合物。[未提及的某种微生物]生长采用稀释法检测，孔隙率通过光学显微镜检查。数据采用单因素方差分析（P < 0.05）和相关性分析进行计算。
添加2%壳聚糖和丙烯酸的丙烯酸树脂呈现出几乎为球形且尺寸最小的孔隙。所有组之间观察到显著差异（P < 0.05）。孔隙率与[未提及的某种微生物]生长之间存在正相关且极强的相关性。
1%和2%浓度的壳聚糖和丙烯酸可添加到丙烯酸树脂中，以最小化义齿基托的孔隙率并减少[未提及的某种微生物]的生长。孔隙率较低的义齿与较低的[未提及的某种微生物]生长速率相关。
