Success or failure of endodontic treatments: A retrospective study.

CONTEXT: Well-conducted endodontic therapy is necessary for the dental rehabilitation of the individuals with cleft lip and palate.

AIM: The aim of this study was to verify the success and failure index of endodontic treatments performed in the Endodontic Sector of the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo, (HRAC/USP), Bauru, Brazil.

MATERIALS AND

METHODS

The preservation records (at least 2 years) of the endodontic treatments performed in the HRAC/USP were verified, indicating the success or failure of the treatment, and these treatments were divided into three groups (vital pulp, necrotic pulp, and endodontic retreatment). The Chi-square statistical test was applied with a significance level of 5%.

RESULTS

A total of 1216 endodontic treatments were quantified with a minimum of 2 years of prenatal care at HRAC/USP. The vital pulp group had a success rate of 99.4% (535 treatments) and 0.6% failure (3 treatments), 98.6% of success in the necrotic pulp group (577 treatments) and 1.4% failure (8 treatments), and 95.6% success rate (89 treatments) and 4.4% failure (4 treatments) in the endodontic reintervention group.

CONCLUSION

From the results found, we can conclude that there was a high success rate in the treatments and endodontic retreatments performed in the Endodontics Sector of the HRAC/USP, considering that well-conducted endodontic therapy is extremely important in the oral rehabilitation of individuals with cleft lip and palate.
