Abstract
Objectives: The aim of this study was to evaluate the effect of different acidic agents on surface roughness of feldspathic porcelain. Materials and Methods: In this study, totally 60 disc shaped Noritake and Ceramco 3 feldspathic porcelain were used. The samples were divided into five groups and immersed in five acidic agents (coke, orange juice, lemonade, mineral water and black-carrot juice). After 168 hours, the specimens were evaluated surface roughness with profilometer. Results: The results showed that the highest surface roughness value (4.46 ± 2.9 μm) was identified in lemonade at Noritake porcelain and the lowest surface roughness value (1.06 ± 0.56 μm) was identified in mineral water at Ceramco 3 porcelain. The result of two-way analysis of variance test showed that there were no statistically significant differences between acidic agents on surface roughness of feldspathic porcelain (p > 0.05). Conclusions: The obtained data presented that the acidic drinks affected the surface roughness of feldspathic porcelain.
Highlights
Dental porcelains have esthetic properties, biocompatibility and wear resistance, so they are being used in dentistry [1]

Summary
Dental porcelains have esthetic properties, biocompatibility and wear resistance, so they are being used in dentistry [1]. Porcelain fragile structure is decreased the using for many years. The fracture of on the porcelain surface and the degradation of surface finish, as opposed to the attrition on the teeth as well as increased accumulation of plaque causes. Rough porcelain surfaces significantly reduce the strength of ceramic restorations and make them prone to fracture [2] [3]. How to cite this paper: Duymus, Z.Y., Ozdogan, A. and Ulu, H.
