“…They carried out the study in a distilled water setting with a 90-day term ageing similar to our study. 16 Another study by Sameeh et al in 2021 19 also supported our results wherein they conducted a study comparing the surface hardness of two silicone based soft denture liners mainly Voco and Mollosi with three different denture cleansers (Periogard, Secure, and Polident. When compared to Voco soft liners with three different denture cleanser groups in the first week and first month, Mollosil soft liners demonstrated a highly significant increase in surface hardness.…”

Aim To investigate the hardness and energy absorption of four commercially available chairside types of silicone materials and compare their properties with heat-cured silicone material. Materials The chairside materials investigated were GC reline soft, mucopren soft, sofreliner soft and elite soft relining. The heat-cured polymer silicone material was Molloplast B. All soft lining materials were processed according to manufacturers’ instructions. Two properties were investigated. Ten specimens for each test were prepared for each soft liner except for the water absorption and solubility test, for which only five specimens were prepared. The specimens of energy absorption (10 × 10 × 3 mm) were tested using a Lloyd instruments testing machine. Hardness specimens (38 × 38 × 3) were tested using a shore A durometer and were divided into two subgroups; dry and wet storage. Results The specimens of energy absorption (10 × 10 × 3 mm) were tested using a Lloyd instruments testing machine. Sofreliner soft was significantly softer than Molloplast B. GC reline soft was significantly harder than molloplast B. At high loads, sofreliner soft and elite soft relining was significantly more resilient than molloplast B. Mucopren soft was significantly stiffer than Molloplast B. At low loads, all materials showed similarities in stiffness and resilience; the difference between them was insignificant. After one month of immersion, GC reline and mucopren significantly increased hardness values. Conclusion In all conditions and at all four-time points, the hardness values for GC Reline soft were the greatest, and hardness values for Sofreliner Soft were the least. Some chairside soft denture lining materials could have similar significant properties to molloplast-B, such as sofreliner soft and elite.

“…Periogard had glycerine, propylene glycol, and chlorhexidine gluconate; secure had sodium perorate monohydrate, trisodium phosphate, and sodium bicarbonate; and Polident had tetraacetylethylenediamine, sodium percarbonate, and potassium monopersulfate. These materials used were similar to the research of (Sameeh et al 2021) and (Kreve and Dos Reis, (2019), where authors used similar denture cleansers as in the present study.…”

The purpose of the current research was to evaluate the impact of various denture cleaners on the surface hardness of permanent silicone denture lines. In the present study, 124 specimens were included comprising of soft liners made of permanent silicone, which were made from the 15 mm x 10 mm custom metal mold dimensions, where 62 samples were made of Molossil™ and 62 other of Voco™ which are commercially available liners for permanent dentures. These samples were then divided into 4 groups of equal specimen numbers (n=32) depending on the cleansing treatments. Group I specimens were cleaned with water daily, and Group II Polident™ Group III was given SecureTM denture cleaning solution, while Group IV was given PeriogardTM denture cleaning solution. The samples were assessed at 1st week, 1st month, and 6th month after cleanser use. The study results showed that at the 6th-month follow-up after the use of denture cleansers, all of the samples had considerably increased surface hardness compared to the baseline. Statistically significant results were seen with Periogard™, Secure™, and Polident™ compared to Group I controls. In Voco™ denture liners, minor changes were seen compared to Molossil™ soft liners with time in all the groups. The results of this investigation are significantly well cleansing action is seen with Voco™ soft denture lining material compared to Mollosil™ soft denture lining material, and surface hardness is least affected by Polident™ denture cleanser compared to Secure™ and Periogard™ denture cleansing agents.

Disinfection of dentures and resilient denture liners were preferred for cross-contamination treatment and better safety. Nevertheless, it has been found that these techniques affect the physical and mechanical properties of denture liners. Objective: To evaluate the impact of various disinfection methods on the tensile bond strength of acrylic soft liner. Material and Methods: 25 samples were made, then divided randomly into five groups (4 disinfection groups as well as a control group), after the daily disinfection procedure, distilled water was used to store the samples at room temperature. After 30 days, a universal testing device (Gester, China) was used to assess the tens ile bond strength. The machine applied force to the specim ens at a crosshead constant speed of 5 mm/minute until failure was recorded. Statistics software (SPSS) was used to analyze the measurements. Results: After 30 days of regular ex posure to different disinfection methods, a greater mean value for bond strength showed in the control group while the lesse r value was in the chlorhexidine group. No significant difference was found between the control and Protefix tablet groups. The sodium hypochlorite and microwave groups had no significant difference between them, but they were significantly different from the control, Protefix tablet, and chlorhexidine groups. the chlorhexidine group was significantly different from the control and other disinfected groups. Conclusion: All disinfected soft liners revealed a decrease i n tensile bond strength, which was not significant with the protefix cleansing tablet but significant with the chlorhexidine, sodium hypochlorite, and microwave regimes.
