A retrospective clinical evaluation of success rate in endodontic-treated premolars restored with composite resin and fiber reinforced composite posts

Abstract

Background:The aim of this retrospective study was to assess the survival rate and causes of failure of quartz fiber posts used to restore endodontically treated teeth.Materials and Methods:Thirty-eight patients with endodontically treated premolar and anterior teeth that were then restored with a coronoradicular quartz fiber post and extensive composite resin restorations were selected for participation in the study. The age of the restorations ranged from 1 to 6 years. Survival probabilities of the restorations as well as causes of failures were analyzed using the Kaplan-Meier analysis and the Logistic regression (α = 0.05).Results:The overall cumulative survival rate (48.8%) was determined, while the survival probabilities after 1, 2, 4, 5, and 6 years of service were 88.37%, 60.95%, 45.71%, 32.65%, and 0%, respectively.Conclusions:The survival probability of endodontically treated teeth restored with a quartz fiber post and composite restorations is associated with the dental arch.

Clinical outcomes and success rates of quartz fiber post restorations: A retrospective study

“…The latter finding was also confirmed in the present study: among the 12 failures in the maxillary arch, more failures occurred in the posterior than the anterior teeth, at a ratio of 2 to 1 ( Table 2). In a previous retrospective study, 30 the dental arch was found to be a significant predictive factor of failure, with teeth in the maxillary arch having a higher failure rate than teeth in the mandibular arch, as in the present study. Conflicting observations have been reported, with some studies showing a greater percentage of failures in the anterior sector than the posterior, 23,31 while others have reported the opposite.…”

“…26,27 Despite the increasing use of clear-colored and lightconductive fiber posts, few longitudinal studies of this type of restoration have been performed, particularly over the medium and long term. [19][20][21][28][29][30] Ferrari et al 19 analyzed different types of carbon and quartz fiber posts and demonstrated a low failure rate of 3.2% at 6 years, with no failures due to root fracture. Studies on glass fiber posts reported a failure rate of 12.8% at 2 years, 20.1% at 5 years, and 32.5% at 6.5 years.…”

“…3 Post debonding is one possible failure caused by the complexity of bonding to root canals. 4,5 Another commonly reported failure is fracture of the post and/or core.…”
