Therapeutic modalities employed in the treatment of maxillofacial malignancy, tumor resection, radiation and chemotherapy, can result in local and systemic changes in healthy oral tissues many years after anticancer therapy has been stopped. The immunologic status of a select group of nine individuals who underwent surgery of the maxillofacial region and after head and neck irradiation, with severe and persistent denture stomatitis was studied. A significant impairment of granulocyte and lymphocyte functions and increased concentrations of serum IgG, as compared to healthy controls, were found in the patients of the study group. It is concluded, that this group of patients show immunological abnormalities many years post therapy, which must be recognized by the clinician in order to effect a cure.

Oral candidiasis, predominantly caused by , presents significant challenges in treatment due to increasing antifungal resistance and biofilm formation. Antimicrobial photodynamic therapy (aPDT) using natural photosensitizers like riboflavin and hypericin offers a potential alternative to conventional antifungal therapies. : A systematic review was conducted to evaluate the efficacy of riboflavin- and hypericin-mediated aPDT in reducing Candida infections.

Background: Polymethyl methacrylate (PMMA) is ideal for denture bases but is prone to biofilm accumulation, leading to denture stomatitis (DS), often involving . Dimethylaminohexadecyl methacrylate (DMAHDM) and 2-methacryloyloxyethyl phosphorylcholine (MPC) are introduced into dental materials for their antimicrobial and protein-repellent properties. This study investigates the effects of incorporating dimethylaminohexadecyl methacrylate (DMAHDM) and 2-methacryloyloxyethyl phosphorylcholine (MPC) into heat-polymerized (HP) and 3D-printed (3DP) denture base resins on microbial adhesion and cytotoxicity.

Purpose: To determine the effects of K18 quaternary ammonium methacryloxy silane (QAS) on tissue conditioner materials and their antimicrobial properties.
Methods: 30% K18 QAS in methyl methacrylate (MMA; K18-MMA; 0%, 15%, and 20% w/w) was incorporated into a commercial tissue conditioner (Coe comfort). The degree of curing (Shore A hardness), hydrophilicity (contact angle), flow, liquid sorption, mass loss, and antimicrobial properties of Streptococcus mutans, Streptococcus sanguinis, and Candida albicans were determined.

Statement Of Problem: Acrylic denture base resins are subject to colonization by oral and nonoral bacteria, contributing to the onset of denture stomatitis. However, how the addition of antimicrobial substances affects the mechanical and optical properties of additively manufactured denture base resin remains unclear.
Purpose: The purpose of this in vitro study was to investigate the surface roughness, color stainability, and flexural strength of antimicrobial-modified, additively manufactured polymethyl methacrylate (PMMA) denture base resin in tooth and gingiva colors.

Statement Of Problem: Denture stomatitis (DS) is a common oral disorder in patients with complete maxillary dentures. Typical treatments such as nystatin or azoles lead to drug resistance after a long period. Several studies have shown the antifungal activity of statins against Candida albicans; however, studies on the antifungal effect of atorvastatin against DS are lacking.
