There are three types of composite resins Conventional(Packable), Flowable(Bulkfill),Microfill. Hybrid,Fluoride releasing composites. Color change of composite restoration in different color media during the time is a common problem in esthetic dentistry, causing the need to replace restoration and spending a great deal of cost and time to patients. The aim of this study is to present a short review of recent literature available on the association of colour stability of composite resins. The article was done after reviewing several articles on the colour stability of composite resins. The effect on colour stability of composite resins depends on type of solution exposure time and composition of material.
