SUMMARY Composite resin may make a restoration noticeable as time passes, on account of its color instability. The repair technique is a minimally invasive treatment for class IV composite resin restorations that show unsatisfactory coloration. Thus, the objective of the present article was to report a clinical case involving a conservative technique used for repairing a class IV composite resin restoration in the left maxillary central incisor and the replacement of a class IV restoration in the right maxillary central incisor.

Aim: This case report aimed to discuss the clinical sequence and the indications of the direct veneer technique with composite resin to mask a discolored tooth. Case report: A 18-year-old male patient attended a Dental School for treatment of the maxillary central incisors. During the initial examination, the patient reported a dental traumatism in childhood fracturing both teeth. Tooth 21 had already been endodontically treated, and the patient complained of the darkened color, while tooth 11 had been fractured for a long time. Results: Poor class IV composite resin restoration was found, showing rests of endodontic material on tooth 21 and class IV dental fracture on element 11. The elements were cleaned, restorative materials were removed and composite resin veneers were made using a silicone guide technique. Finishing and polishing were performed in the next session, reproducing some of the peculiar characteristics of young teeth, consistent with the patient's age, such as macro and microtextures. Conclusion: The use of direct veneers in composite resin proved to be efficient to restore the aesthetics of darkened and fractured teeth, restoring aesthetic satisfaction through the transformation of the patient's smile.

In this in vitro study, the surface alterations of enamel and dentin in cavities prepared by Er,Cr:YSGG laser irradiation was investigated by scanning electron microscopy and compared to the microleakage degree after composite resin restoration with etched bur cavities in human primary teeth. The results confirmed that laser cavity surface facilitated a good adhesion with the restorative materials; the acid etch step can be easily avoided with the laser treatment.

Objective. The purpose of this study was to test different restoration combinations used for constructing fractured endodontically treated incisors by reattaching their fractured fragments. Methods. Seven types of 3-D FEM mathematical root canal-filled models were generated, simulating cases of (OB) reattaching fractured fragments; (CrPL) reattaching fractured fragments + ceramic palatinal laminate; (CmPL) reattaching fractured fragments + composite palatinal laminate; (CM) reattaching fractured fragments + coronal 1/3 of the root was filled using core material; (BP) reattaching fractured fragments + glass fiber post; (CP) composite resin restoration + glass fiber post; and (OC) composite resin restoration. A 100-N static oblique force was applied to the simulated teeth with 135° on the node at 2 mm above the cingulum to analyze the stress distribution at the tooth. Results. For enamel tissue, the highest stress values were observed in model BP, and the lowest stress values were observed in model CmPL. For dentine tissue, the highest stress concentrations were observed around the fracture line for all models. Conclusions. Reattachment of fractured fragments by bonding may be preferred as a restoration option for endodontically treated incisors; also, palatinal laminate decreases the stress values at tooth tissues, especially at the enamel and the fracture line.
