AI Article Synopsis
- This study evaluated five denture cleansers' effectiveness in reducing microbial adherence and altering the surface texture of different types of denture base resins (conventional, CAD/CAM, and 3D printed).
- The research involved creating acrylic resin discs, contaminating them with specific bacteria, and applying various cleansers, with data analyzed to find effectiveness and surface roughness.
- Results indicated that 2% Chlorhexidine gluconate and sodium hypochlorite solutions were the most effective cleaners, while 3D-printed discs showed the highest microbial growth and surface roughness, suggesting 2% chlorhexidine is a strong recommendation for disinfecting CAD/CAM dentures.
Article Abstract
This study assessed the efficacy of five denture cleansers on the microbial adherence and surface topography of conventional and CAD/CAM denture base resins. Acrylic resin discs were fabricated using conventional, milling, and 3D printing methods (N = 180). The discs were contaminated with dual species of and biofilm for 72 h and then disinfected with either of the denture cleansers (Fittydent cleansing tablets, 2% Chlorhexidine gluconate, 0.2% Chlorhexidine gluconate, 0.5% sodium hypochlorite, and 1% sodium hypochlorite (n = 10). Distilled water served as the control group. The colony-forming units of the microorganisms were calculated, followed by post-treatment surface roughness. Data were statistically analyzed using one-way ANOVA, paired -test, and post hoc Tukey HSD test (α = 0.05). Among the denture cleansers, 2% Chlorhexidine gluconate, 0.5% sodium hypochlorite, and 1% sodium hypochlorite had the best cleansing effect on the resin discs and demonstrated zero growth of colonies for both the species. Comparing the material groups, the 3D-processed discs showed higher colony-forming units followed by the conventional and CAD/CAM milled group. The highest surface roughness was demonstrated by the 3D-printed discs (0.690 ± 0.08 μm), followed by the conventional (0.493 ± 0.11 μm) and the milled groups (0.301 ± 0.08 μm). The tested chemical denture cleansers affected the and adhesion compared to control discs immersed in distilled water. The clinician may recommend to their patient to use 2% chlorhexidine gluconate for the disinfection of CAD/CAM PMMA denture base materials.

Article Synopsis
- The study investigates and compares the retention forces of nylon versus PEEK denture attachments over time and exposure to denture cleansers.
- Two types of attachment materials were tested on models with implants, and dislodgement forces were measured at baseline and after multiple insertion-removal cycles, as well as after soaking in a denture cleanser.
- Results indicated that the frequency of insertion and removal significantly reduced retention values, while soaking in cleanser did not have a significant impact, with blue nylon showing the lowest retention values across the tests.

Objectives: To investigate the effects of denture cleansers on the various properties of CAD/CAM and heat-polymerized polymethyl methacrylate (PMMA).
Materials And Methods: Two different brands of heat-polymerized and two of milled PMMA were fabricated (n = 50), in total 200. Each group was randomly divided into five subgroups (n = 10): control groups (D1) kept in distilled water, cleaning tablets (D2, D3), neutral (D4) and acidic electrolyzed acid water (EAW) (D5).

Article Synopsis
- This research examines how different attachment systems and cleaning methods affect microbial growth on implant-supported overdentures, which are important for patients with tooth loss.
- The study involved testing various denture materials and cleaning techniques, revealing that deeper attachment systems lead to more microbial adhesion and complicate cleaning.
- Combining ultrasonic cleaning with chemical cleaners was found to be the most effective approach for reducing both biofilm and viable bacteria on the dentures, suggesting better cleaning strategies are necessary for maintaining oral hygiene.

Background/objectives: We aimed to assess the antifungal efficacy and impact of a denture cleanser containing extract on the surface characteristics of denture base materials, as well as its physical and biological properties.
Methods: The experimental denture cleansers were formulated with at concentrations of 100 and 150 μg/mL, combined with 1% cocamidopropyl betaine as a natural surfactant. Antifungal efficacy was evaluated using zone-of-inhibition assays against , revealing inhibition zones of 20 ± 1.
Purpose: This study evaluates the antibiofilm action of 2.5 mg/mL peracetic acid (PA), 0.5 mg/mL cetylpyridinium chloride (CPC), and 160 mg/mL N-Acetylcysteine (NAC) against multispecies biofilm of Streptococcus mutans, Staphylococcus aureus, Candida albicans, and Candida glabrata, developed on surfaces of heat-polymerizing acrylic resin (AR) and cobaltchromium (Co-Cr) alloy.
