| Summary: | Background/aim
Debris accumulation beneath the dentures initiates countless difficulties such as inflamed oral mucosa and denture stomatitis. Denture stomatitis is a prevalent pathologic illness that is commonly linked to Candida albicans. Accordingly, treatment requires applying effective anti-inflammatory and antifungal medicaments that do not negatively influence the properties of denture base materials. Antifungal oral gel and ozonated water have quite an impact on inhibiting Candida albicans growth and treating denture stomatitis, so they have been selected in this research. This study aimed to compare the effect of antifungal oral gel and ozonated water on the tensile and compressive strengths of poly methyl metha acrylate (PMMA) and Nylon or polyamide denture base materials.
Patients and methods
This study was carried out for two types of denture base materials; group I PMMA and group II Nylon or polyamide. Total samples for both groups were 160 and fabricated following American Dental Association specifications No.12 for assessing tensile and compressive strengths. For each group (80 samples each group), the compressive strength was measured before (10 samples each) and after (10 samples each) the application of antifungal oral gel (10 samples each), and ozonated water (10 samples each), overnight for 15 days for each. Also, the tensile strength was measured for each group before (10 samples each) and after (10 samples each) the application of antifungal oral gel (10 samples each) and ozonated water (10 samples each) overnight for 15 days for each. Comparison between pre and post measurements was accomplished by Paired t-test, while comparison between heat-cure PMMA and nylon was carried out by using an Independent t-test.
Results
PMMA was significantly affected by ozonated water regarding compressive (P =0.0001) and tensile (P =0.0001) strength while antifungal oral gel had a significant effect only on the tensile strength (P =0.0001) but not the compressive strength (P =0.57). Both antifungal oral gel (P =0.7) and ozonated water (P =0.75) have insignificant effects on the compressive strength of nylon denture base material and also insignificant effect on tensile strength of nylon denture base material (P =0.16) for ozonated water and (P =0.37) for antifungal oral gel.
Conclusion
Ozonated water could adversely impact both the compressive and tensile strength of PMMA denture base material and the antifungal oral gel could affect only its tensile strength. Ozonated water and antifungal oral did not affect the compressive and tensile strength of the nylon denture base material. |
