Background: Regular usage of denture cleansers is recommended in complete denture wearers for effective plaque control, and these cleansers alter the physical properties of acrylic resin over a period of time. Thus, an study was carried out to assess the effect of denture cleansers on the color stability of heat-cure denture base resin.
Aim: The aim of the present study was to evaluate the effect of commercially available fast-acting denture cleansers on the color stability of heat-cure denture base resin at different time intervals.
Materials And Methods: Thirty-six heat-cure acrylic resin (Ivoclar Triplex Hot-V) specimens are randomly allocated into four groups - Group A (distilled water as control); Group B (polident - 3 min); Group C (fixodent scope plus); and Group D (stain away plus) comprising of nine samples each. After recording the baseline values, the specimens were immersed in their respective cleansing solutions for a prescribed time interval. This procedure was repeated daily, and the color change (ΔE) was evaluated after 90 and 180 days interval using a colorimeter in a standard "Commission International de l'Eclairage" color system.
Statistical Analysis Used: Paired -test and Dunnett's T3 test.
Results: All the groups exhibited a variable color change (ΔE) for an immersion period of 90 days. However, significant color differences ( = 0.001) were noticed among the test groups after 180 days.
Conclusion: The color change of denture base resin was greater for Group D followed by Groups B, C, and A respectively after 180 days of immersion. The ΔE values of all test groups increased with time.

Among individuals who wear removable dentures, there is a significant likelihood, reaching up to 70 %, of experiencing a condition known as denture-induced stomatitis. To address this issue, a commonly used method involves soaking dentures in denture cleansers to eliminate microorganisms. However, the prolonged use of this cleaning method has resulted in the emergence of drug resistance.

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.
