The effect of nano titanium oxide particle incorporation on characteristic of denture base material

The objective of this study is to prepare and study chemical compounds for cleaning denture from locally available materials. The chemical compounds solutions were (sodium bicarbonate with alum), (sodium bicarbonate with citric acid), (sodium bicarbonate with apple vinegar), (sodium bicarbonate with clear commercial vinegar), (sodium bicarbonate with thyme oil), (saturated salt solution), (clear commercial vinegar), (alum). The main study, the effects of the chemical compounds solutions were evaluated on the (color, water Sorption and transverse strength) of heat cured denture base material. The t-test showed that the highest increase in optical density for the specimens immersed in (alum), (sodium bicarbonate +alum), (sodium bicarbonate + apple vinegar) solutions at 1/2 hr immersion and it increased more at 8 hrs immersion. The conclusions of this study showed that the safest prepared solutions on the denture base material that could be used as denture cleansers are (sodium bicarbonate{7g}with clear commercial vinegar{5ml}), (sodium bicarbonate {2g} with thyme oil {3.57g}), (saturated salt solution {40g}) at 1/2 hr and 8 hrs of immersion. While, (sodium bicarbonate {2g} with citric acid {4.57g}) solution appeared its safety at 1/2 hr immersion only.

Styrene Butadiene

This work aims to investigate the tensile and compression strengths of heat- cured acrylic resin denture base material by adding styrene-butadiene (S- B) to polymethyl methacrylate (PMMA). The most well- known issue in prosthodontic practice is fracture of a denture base. All samples were a blend of (90%, 80%) PMMA and (10%, 20%) S- B powder melted in Oxolane (Tetra hydro furan). These samples were chopped down into specimens of dimensions 100x10x2.5mm to carry out the requirements of tensile tests. The compression strength test specimens were shaped into a cylinder with dimensions of 12.7mm in diameter and 20mm in length. The experimental results show a significant increase in both tensile and compression strengths when compared to control (standard) results for the preparation material.

Bioactive Agents

Denture stomatitis is a multifactorial pathological condition of the oral mucosa that affects up to 72% of denture wearers. It is commonly seen on the palatal mucosa and characterized by erythema on the oral mucosa that are in contact with the denture surface. The aim of this study was to incorporate 2-methacryloyloxyethyl phosphorylcholine (MPC) and dimethylaminohexadecyl methacrylate (DMAHDM) into a high impact polymethylmethacrylate heat-cured denture base acrylic resin as a potential treatment for denture stomatitis. We used a comparative study design to examine the effect of incorporating MPC as a protein repellent agent and DMAHDM as an antifungal agent to prevent the adherence of Candida albicans to the denture base material. The dual incorporation of MPC and DMAHDM reduced C. albicans biofilm colony-forming unit by two orders of magnitude when compared to the control group devoid of the bioactive agents. Although the addition of MPC and DMAHDM alone or in combination significantly reduced the flexural strength of the material, they showed reduced roughness values when compared to control groups. This new denture acrylic resin provides the benefit of enhancing C. albicans biofilm elimination through dual mechanisms of action, which could potentially reduce the prevalence of denture stomatitis.
