Estudos sobre procedimentos restauradores de dentes tratados endodonticamente : ensaio clínico randomizado e estudo retrospectivo

Abstract

Objective: To evaluate, in vivo, the survival of composite resin restorations using the conventional technique or composite resin restorations with transfixed fiberglass post. Materials and Methods: Twenty-two patients and 24 teeth were included in the study, 12 in Group 1 (conventional) and 12 in Group 2 (transfixed fiberglass post). The restorative technique was randomly assigned into the two groups. After the restorative procedures, the restored teeth were evaluated following the modified USPHS criteria at 6 months, 1 year and 2 years. Fisher's exact test compared the two restorative techniques in each clinical criterion and in each assessment. McNemar's test compared the clinical criteria at 6 months, 1 year and 2 years for each restorative technique. The significance level was 5%. Results: There was no statistical difference between the restorative techniques, as well as among the assessments (p>0.05). Conclusion: At 2-year evaluation, the restorations with transfixed fiberglass post showed performance comparable to the conventional composite resin restorations.
