BIOCOMPANTIBILITY OF COMPOSITE MATERIALS; A LITERATURE REVIEW

Today, quite number of different materials presently available in restoration of tooth such as resin based restorative materials. adhesive materials are rapidly becoming one of the important materials in restorative dentistry. during the application, most of these materials are in contact with dental hard tissues, soft tissues and oral liquids (e.g. saliva, gingival crevicular fluid). despite of being considered highly stable structures, composite materials are susceptible to degradation due to the incomplete polymerization and the influence of the aqueous oral environment. a lot of studies indicated that various components may be released from composite restorations into the oral environment. the elution of components from composite resins may influence the biocompatibility of the restorations. substances eluted from the polymerized materials (residual monomers, additives and degradation products) may irritate the soft tissue, stimulate the growth of bacteria and promote allergic reactions. thus, in the selection of new material, besides the mechanical and physical properties also biological characteristics must be taken care. in this study, articles about biocompantibility of composite materials were reviewed.
