Strategies for Preventing and Treating Oral Mucosal Infections Associated with Removable Dentures: A Scoping Review.
Antibiotics (Basel)
March 2024
Article Synopsis
- Oral infections linked to dentures arise from biofilms on denture surfaces contacting mucosal tissues, prompting a study on prevention and treatment strategies.
- The research involved analyzing 935 articles from various databases, narrowing it down to 104 relevant studies that fit their criteria, including 38 additional articles from gray literature.
- Key findings highlighted increased interest in antimicrobial solutions integrated into dentures and improved hygiene practices, particularly noting the effectiveness of brushing with sodium hypochlorite and promising new disinfectants.
Purpose: To evaluate the color stability (ΔE), surface roughness (ΔRa), and flexural strength of denture base acrylic resin after short (20 minutes) and long-term (8 hours) immersions simulating a period of 5 years of use.
Methods: 120 disk-shaped (16 mm x 4 mm) and 120 rectangular (65 mm x 10 mm x 3.3 mm) specimens were prepared (Lucitone 550) and distributed into three groups (n=20): distilled water (Control); Corega Tabs (CT) and Polident (Po), for immersions of 20 minutes and 8 hours.
Purpose: To evaluate the effect of different forms of denture adhesives on the formation of biofilm and on adhesive strength, as well as the effectiveness of hygiene protocols for their removal.
Materials And Methods: Samples of the heat-cured polymethyl methacrylate denture base resin were made and divided into four groups: control (no adhesive), ultra Corega cream, Corega strip adhesive, and ultra Corega powder (GlaxoSmithKline). Biofilm formation was evaluated by counting colony-forming units and fluorescence microscopy.
It is important to choose an appropriate brush for denture cleaning to prevent damage to the surface properties of prosthetic devices. The purpose of this study was to evaluate the abrasiveness of toothbrushes and denture brushes on boiled and microwave-processed acrylic resins. Specimens of 4 resin brands were prepared (n = 30).

Purpose: The purpose of this in vitro study was to evaluate the growth of Staphylococcus aureus and Pseudomonas aeruginosa on the surface of autopolymerizing (AP) and heat-polymerizing (HP) acrylic resins incorporated with nanostructured silver vanadate (β-AgVO3) and its impact strength.
Material And Methods: For each resin, 216 circular specimens (9 × 2 mm) were prepared for microbiologic analysis and 60 rectangular specimens (65 × 10 × 3.
Background: Osteoarthritis (OA) is the most common form of arthritis of the temporomandibular joint (TMJ), and can often lead to severe pain in the orofacial region. Management options for TMJ OA include reassurance, occlusal appliances, physical therapy, medication in addition to several surgical modalities.
Objectives: To investigate the effects of different surgical and non-surgical therapeutic options for the management of TMJ OA in adult patients.
Purpose: This study aimed to measure the color change, surface roughness and flexural strength of heat-polymerized acrylic resin after its immersion in denture cleansers, simulating a 180-day use.
Methods: Thirty disk-shaped (15mm x 4mm) and 30 rectangular samples (65mm x 10mm x 3.3mm) were prepared from heat-polymerized acrylic resin and immersed in Corega Tabs, Bony Plus, and distilled water.

Background: Removing denture plaque may be essential for maintaining the oral health of edentulous people. Brushing and soaking in chemical products are two of the most commonly used methods of cleaning dentures.
Objectives: To evaluate the effectiveness and safety of different methods for cleansing removable dentures.
Objectives: The objective of this study was to evaluate the accuracy and reproducibility of three complete denture biofilm indices (Prosthesis Hygiene Index; Jeganathan et al. Index; Budtz-Jørgensen Index) by means of a computerised comparison method.
Background: Clinical studies into denture hygiene have employed a large number of biofilm indices among their outcome variables.
The DNA Checkerboard method enables the simultaneous identification of distinct microorganisms in a large number of samples and employs up to 45 whole genomic DNA probes to gram-negative and gram-positive bacterial species present in subgingival biofilms. Collectively, they account for 55%-60% of the bacteria in subgingival biofilms. In this study, we present the DNA Checkerboard hybridization as an alternative method for the detection and quantitation of Candida species in oral cavities.

Materials And Methods: The experimental dentifrices comprised two compositions. One was based on the addition of 1% chloramine T (D1) and the other on the presence of 0.
