“…Therefore, these observations might illustrate the lowering in bond strength of the acrylic soft liner in the present study after immersion in disinfectant solutions (Protefix cleansing tablet, 2% NaOCl, and 2% CHX) as compared to the control, and the bond strengths of these chemically different disinfectant groups were significantly different from each other. The findings from this study on the influence of NaOCl on tensile bond strength disagree with that of Nakhaei et al (2019) (14) when they considered that ozone and two commonly used denture cleaners (NaOCl and Corega tablets) had no effect on the adhesive strength of a silicone soft liner to acrylic denture base material. However, there are differences between the two studies in the type of soft liner, immersion period, and NaOCl solution concentration.…”

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.

“…15 Research revealed that the oral Grampositive and Gram-negative bacteria as well as Candida albicans were killed by immersion in ozonated water for one hour. 16 Another study by Arita et al, 17 showed that the use of ozonated water resulted in a decrease in Candida albicans counts Nakhaei et al, 18 evaluated the effect of ozone and two common denture cleansers on the surface hardness and bond strength of a siliconebased soft liner to the acrylic denture base material. A few studies have reported on the effects of ozone on the mechanical properties of the denture, so the present research was carried to study the effects of ozonated water compared to the microwaving on the tensile strength of heat-cured resins in two periods of exposure (at 1 day and 7 days).…”

Background: There is a need for safe disinfection methods without a detrimental effect on the acrylic denture base. Aim: the purpose of the current study was to evaluate the effect of ozonated water and two protocols of microwave disinfection on tensile bond strength of high-impact acrylic. Material and methods: Eighty samples were divided into four major groups: one control and three experimental groups, 20 specimens each. The experimental groups each received either disinfection by ozonated water, microwave 850W/1min, or microwave 650W/6min. Further division of the major groups into two sub-groups depending on the number of disinfection cycles and total immersion time in distilled water: One cycle and one day versus seven cycles and seven days. The control group specimens were immersed in distilled water without any disinfection for either one day or seven days. Tensile strength testing was performed on the specimens from the eight groups. The data were analyzed by SPSS version 21#. The ANOVA and Tukey-HSD multiple comparison tests were used for comparison for groups. Results: A non-significant difference in the tensile strength was observed in the groups subjected to one cycle of ozone or microwave disinfection at 850W/1min. There was a significant decrease in tensile strength for the specimens subjected to one cycle of 650W/6min microwaving. The number of testing cycles and storage time in distilled water had a significant impact on the tensile strength of the acrylic in all tested groups, by decreasing it. Conclusion: Ozone disinfection and microwaving at 850W for one minute did not affect the tensile strength of the acrylic, but repeated disinfection over seven days at one cycle per day impaired the tensile strength of the acrylic resin.

“…Estrela et al 26 observed that the addition of ozone to an ultrasonic cleaning system containing different experimental solutions resulted in antibacterial activity against Staphylococcus aureus . Nakhaei et al 27 investigated the effect of ozonated water and two common denture cleaners on the tensile bond strength and hardness of a silicone soft liner. They observed that ozonated water and cleansing tablets (Corega) have a lower effect on the hardness of soft denture liners than that of 0.5% NaOCl.…”

Aim: The aim of this study was to evaluate the effect of the ozonated water on corrosion of a cobalt–chromium (Co-Cr)-based alloy, which is applied for the fabrication of metal frameworks of removable partial dentures. Materials and Methods: In this in vitro study, a total of 30 disk-shaped samples of a Co-Cr alloy were papered and randomly divided into two groups of 15 specimens. In group 1 (control), the specimens were stored in distilled water (DW), and in group 2, the specimens were stored in ozonated water. Around 90 immersions were performed, and the weight change of each specimen was determined. The ion release was analyzed using an inductively coupled plasma-optical emission spectrophotometer. The potentiodynamic polarization test was performed for each group to assess the corrosion resistance of the Co-Cr alloy. The statistical analysis was performed using SPSS version 22. Data were analyzed by independent samples’ t-test. Results: The results showed no significant difference between the weight changes of the two groups. The test using an inductively coupled plasma-optical emission spectrophotometer demonstrated no significant difference between the groups in Co and Cr ions release. In the potentiodynamic polarization test, both groups present similar corrosion behavior, and ozonated water has no deleterious effect on the corrosion resistance and passive range of the Co-Cr alloy compared to DW. Conclusion: As compared to DW, ozonated water has no significant deleterious effect on the corrosion resistance of the Co-Cr frameworks and can be used for cleaning the removable partial dentures.
