RESUMO

Retrospective observations were made on the success rate of endodontic surgery with microsurgical techniques using the resin ionomer Geristore as root-end filling material. Seventy-six cases were treated by one surgeon between 1999 and 2003. For inclusion in this retrospective study, a follow-up examination at 12 months minimum was required. The radiographic findings were evaluated separately by two independent clinicians using the evaluative criteria of Molven et al. (1987). Radiographic diagnosis was complemented by clinical evaluations in which the presence or absence of signs and symptoms indicative of inflamation were observed. Cases were considered successful when the radiographic assessment showed complete healing or incomplete healing (scar tissue) and the absence of signs or symptoms. The data obtained by these evaluations were submitted to Fisher?s exact test and the agreement between the observers verified by Kappa?s test. The following factors were analyzed: surgical indication, status of endodontic re-treatment, tooth type, and observation period. The final success rate was 92.2%. The results of cases classified as successful were considered stable, there was no statistically significant difference between endodontically re-treated and non re-treated teeth, there was no statistically significant difference between the success rates of cases subject to re-surgery and cases surgically treated for the first time; there was no statistically significant difference among the analyzed tooth types. The high success rate and the stability of successful cases observed in this study suggest that the combination of microsurgical techniques, the observance of strict indication criteria and the use of the resin ionomer Geristore as retrofilling material will result in predictable prognosis and in a high success rate of apical surgery
