Sayqa Aziz, Mohsin Malik, Shazana Nazir, Shazia Mir

Background: The denture cleansing and plaque elimination methods employed by a vast majority of patients are restricted to either rinsing under running water or brushing using normal toothbrush and toothpaste. Hence, the present study was conducted for assessing impact of denture cleansers on surface roughness of heat cure acrylic dentures. Materials & methods: TA total of 30 specimens of heat cure denture base resin were fabricated for evaluation of effect of various denture cleaners on surface roughness. Disc shaped wax patterns (10 mm in diameter and 2 mm thick) for surface roughness testing were fabricated using stainless steel mould of desired dimension and were invested in Type III gypsum product in a metallic flask. All the specimens were divided into three study groups as follows: Group A; NaOCl was used, Group B: Vinegar was used and Group C; Control. Surface analyser was used to measure the surface roughness of each disc shaped specimens before and after immersion procedures. All the results were analysed by SPSS software. Results: Mean difference in the surface roughness among specimens of group A, group B and group C was found to be 0.26Ám, 0.12 Ám, and 0.02 Ám respectively. While analysing statistically, it was seen that significant difference exits in relation to mean difference in surface roughness in between three study groups. Conclusion: Surface roughness is increased with sodium hypochlorite in comparison to Vinegar. Key words: Denture, Cleansers, Surface roughness
