Composite resin that have been restored in the oral cavity ages over time and can be fail. The total removal of the restoration is the most common procedure that is often done in daily clinical practice. This procedure may be regarded as overtreatment if only small portions of the restoration has damaged, therefore repairing composite resin could be more effective choice. The bond strength of repairing composite resin can be improved by surface treatment. Surface treatment have been categorized in several method such as surface roughening with diamond bur, air abrasion (sand blasting) with aluminum oxide, chemical treatment (etching) with phosphoric acid or hydrofluoric acid, silane coupling agent and intermediate adhesive resin (adhesive system and flowable composite). The objective of this study was to discuss repairing aged composite resin, surface treatment method that have been practiced and the influence to bond strength of repaired composite resin based on published article. Combination between suface treatment methods will result different values in bonding strength. Up to recent there are no practice best methods yet, however combination air abrasion with adhesive system or with flowable composite improving bond strength that compared to composite resin bond strength without reparation.
