Prosthetic rehabilitation is necessary to improve a patient's quality of life after large cysts and tumors are removed. Although odontogenic keratocysts are benign growths, they usually cause extensive localized damage. Large abnormalities on the affected side are often the outcome of surgery.

- Polymethylmethacrylate (PMMA) is commonly used for dentures but can lead to infections like denture stomatitis due to microbial growth; enhancing its antimicrobial properties is vital for better patient health.
- Chitosan, a natural biopolymer with antimicrobial qualities, was added to heat-polymerized PMMA in varying concentrations (0%, 5%, 10%, 15%) to investigate its effectiveness against oral pathogens.
- The study found that chitosan-reinforced PMMA samples exhibited significantly improved antimicrobial effectiveness compared to conventional PMMA, indicating a promising approach to reduce microbial colonization in dentures.
Objective The objective of this in vitro study was to comparatively evaluate the antifungal and physical properties of tissue conditioner incorporated with nanoparticles (NPs) of different types and concentrations. Materials and methods A total of 198 tissue conditioner samples were used in this study. The samples were categorized into a control group, namely, tissue conditioner without NPs (Group 1), and test groups, namely, tissue conditioner incorporated with zinc oxide (ZnO) NPs (Group 2) and magnesium oxide (MgO) NPs (Group 3).

The prosthetic rehabilitation of such patients is challenging. The objective of prosthetic treatment of an ocular defect is to provide a well-fitting ocular prosthesis that closely resembles the original eye, restoring the patient's self-confidence and social acceptance.
