Farklı pürüzlendirme yöntemlerinin mine renklenmesi üzerine etkisi / Examination of different etching techniques on enamel color

Abstract

The aim of this study is to evaluate the effects of four different enamel etching method and two different composite adhesives on enamel color change. In this study, 120 human premolar teeth extracted for orthodontic purposes were used. Teeth were randomly divided into four etching groups of 37% orthophosphoric acid, Er:YAG laser QSP mode, MSP mode and X-Runner handpiece. Metal brackets are bonded with two different composite adhesives, Transbond XT and Transbond Plus Color Change. After bonding procedure, samples were stored in the staining solution. Color measurements were made by spectrophotometer after bonding and debonding. L, a and b color parameters were recorded according the Cielab and ΔE color differences were calculated using the formula. Statistical analyzes were performed with the SPSS 24.0 software package. The findings of the study show that the coloration related to the orthodontic treatment varies with the different etching methods and the use of different adhesives. However, these values are above the 0.05 p value which makes a statistically significant difference in terms of different etching methods and applications of composite adhesives. In conclusion, this study, which represents the coloring that occurs during orthodontic treatment, did not reveal any significant difference in color in the teeth.
