ABSTRACT:-
INTRODUCTION: Surface roughness is a surface irregularity of the material. Resilient soft lining materials are helpful for the management of patients with removable prosthesis who are unable to withstand the hard denture base with thin underlying mucosa, resorption of the residual ridge, severe undercuts and heavy and unequal distribution of occlusal loads. Use of soft liners employed as tissue conditioners, functional impression materials and temporary reliners of ill-fitting removable dentures. These materials can be used as interim liners within the healing periods after implant placement. The aim of the study is to determine the surface roughness of soft tissue liner before and after immersion with carbonated drinks. MATERIALS AND METHODS: 10 samples of soft tissue liners discs were made with a diameter of 10mm and thickness of 4mm. a 2μm/60 stylus was used to measure the surface roughness. Pre immersion surface roughness was measured for 10 samples using Mitutoyo SJ-310 Stylus profilometer. All the data were tabulated. Using the “SPSS software” ,values were presented in the form of bar charts. RESULTS: Carbonated beverages like coke and sprite influenced the surface roughness property of soft tissue liners, by increasing the roughness parameters post immersion for 24 hours. When compared with coke, sprite drink shows a more significant increase in surface roughness. P value obtained using chi square test was greater than 0.05, hence it is statistically not significant. CONCLUSION: Within the limitations of study, it is concluded that there was an increase in the surface roughness of the soft tissue liner when immersed in carbonated beverages like coke and sprite. Surface roughness of soft tissue liner material immersed in sprite drink showed increased roughness values when compared to the material in coke drink.
