Abstract

Objective: To investigate the color matching of the composite resin used for repaired with initial composite resin restoration after the aging process. Material and Methods: After preparation of 30 composite resin samples, their color were determined using the spectrophotometer four times and the average was recorded. After the initial aging, the color of the samples was measured again. Then, the repair process was performed with an appropriate composite resin color for each sample and the aging process was performed again. After the second aging, the color of the initial and the repaired composite resins were measured. Then, the data were analyzed by paired T-test. The level of significance was set at 5%. Results: The color difference of the initial composite resin between before and after initial aging, as well as the color difference of repaired composite resins between before and after second aging, were significant (p<0.001). Also, after the second aging, the color difference between initial and repaired composite resin restoration were significant (p<0.001). Conclusion: The color matching of the repaired composite resin with the initial one is not acceptable. In this way, replacement of initial composite suggested instead of repaired.

Summary

Introduction

Color change is one of the most common causes of repeated replacement of composite resin restorations. Among the dental restorative materials, resin composite resins have been found to be highly accepted among dentists and patients due to their adequate strength, excellent primary esthetic, lower cost than ceramics, and dentin bonding [2]. The success of restorative materials such as composite resins mostly depends on their color stability over time. Color change is one of the most common causes of frequent replacement of composite resin restorations, dissatisfaction among patients, and the associated economic problems for the patients [1,3]. Composite resin color change can be caused by internal or external factors. Internal factors induce changes in the resin matrix and the interspersed matrix and filler. The external factors include the absorption of foreign pigments, smoking and the consumption of food and drink [4,5]
