Objective 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
Streptococcus mutans.
Materials and Methods This study is an experimental laboratory research. Samples
were divided into the following three groups (n ΒΌ 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. S. mutans growth was tested using the dilution method, and porosity was examined using an optical
microscope. Data were calculated by one-way analysis of variance (p < 0.05) and
correlation analysis.
Results The acrylic resin added with 2% chitosan and acrylic acid showed pores with
an almost spherical shape and the smallest size. Significant difference (p < 0.05) was
observed among all the groups. A positive and extremely strong correlation was found between porosity and S. mutans growth.
Conclusion 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
S. mutans. A less porous denture is associated with a low S. mutans growth rate.
