Removable denture wearers are at an increased risk of developing periodontal diseases due to biofilm deposition and microbial colonization on the denture surface. This study aimed to characterize and compare the metagenomic composition of saliva in denture wearers with different periodontal statuses. Twenty-four community-dwelling elders were recruited and grouped into denture wearers with active periodontitis (APD), non-denture wearers with active periodontitis (APXD), denture wearers with stable periodontal health conditions (SPCD), and non-denture wearers with stable periodontal health conditions (SPCXD). Saliva samples were collected and underwent Type IIB restriction-site-associated DNA for microbiome (2bRAD-M) metagenomic sequencing to characterize the species-resolved microbial composition. Alpha diversity analysis based on the Shannon index revealed no significant difference between groups. Beta diversity analysis using the Jaccard distance matrix was nearly significantly different between denture-wearing and non-denture-wearing groups ( = 0.075). Some respiratory pathogens, including and , were detected as the top 30 species in saliva samples. Additionally, LEfSe analysis revealed a substantial presence of pathogenic bacteria in denture groups. In the cohort of saliva samples collected from community-dwelling elders, a remarkable abundance of certain opportunistic pathogens was detected in the microbial community.

This study investigated denture care attitudes, dental visit habits, oral mucosal lesions, and hygiene levels in 118 complete denture users treated at a university dentistry faculty. Data on demographics, smoking, denture use duration, dentist visits, and hygiene habits were collected via a questionnaire. A specialist examined mucosal lesions and assessed denture hygiene level using the Budtz-Jorgensen and Bertram method.

Purpose: This mini-review discusses the clinical implication of respiratory pathogens in the biofilm on acrylic resin removable dentures in the elderly.
Methods: A search was conducted using the keywords: "dentures", " acrylic resin", "biofilm", "pneumonia", "elderly", "respiratory pathogens", and "respiratory diseases" in databases PubMed/Medline, Lilacs, SciELO and textbooks between 1999 and 2024.
Results: The elderly are more susceptible to chronic diseases and/or life-threatening infections because of senescence itself and functional and degenerative alterations.

Conventional complete denture wearers often complain of lack of stability and overall discomfort with their prostheses. The advent of dental implants and advanced prosthetic methods have greatly improved this struggle for edentulous patients. The utilisation of computer-aided design and computer-aided manufacturing (CAD-CAM) technology has only further enhanced the capabilities of dental practitioners to rapidly and accurately restore edentulism.

Background Mandibular ridge resorption is a common problem in edentulous individuals, particularly in post-menopausal women. Body mass index (BMI) has been suggested as a potential factor influencing ridge resorption, but the relationship between the two remains unclear. Methods A study was conducted to evaluate mandibular ridge resorption in post-menopausal denture-wearing females and its relation to body mass index.
