Abstract

Abstract Background: Endodontically treated teeth need to be restored in amanner to provide protection for the remaining tooth structure but would also allow the restoration of esthetic and functional demands. Objectives: This study evaluates the clinical success rate of endodontically treated premolars restored with different techniques. Methods: In this study, 96 participants were included with indication of endodontic treatment of one maxillary or mandibular premolar. Only cases with premolars along with MOD Class II carious lesions and preserved cusp structure were recruited. After endodontic treatment subjects were randomly assigned to one of the following restoration methods: (1) composite restoration without any cusp reduction(2)Composite associatedwithafiber reinforced composite (FRC) post (3) capping the buccal and lingual cusp and composite restoration. Subjectswere recalled for the clinical and radiographical evaluationswithmodifiedUSPHS criteria after three, six and 12months. Results: During the evaluation period, all the threemethods of restoration, achieved the Alpha degree in termof modified USPHS criteria. Conclusions: The clinical success rates of endodontically treated premolars restoredwith fiber posts and direct composite restora- tions, direct composite restorationswithcuspcapping andsimpledirect composite restorationwereperfect after one year of follow- up evaluation.
