Resumo:
The present study aimed to evaluate through clinical and radiographic examination the
evolution and success index of the endodontic treatment performed using the apical
foramen enlargement technique. It is an observational, cross-sectional, descriptive
study that, through the analysis of 397 records, 162 patients met all the inclusion
criteria and were selected for the study, of which 25 of which 25 attended for
participation in the study. All were submitted to clinical and radiographic examination
for the analysis of each case, which presented a proservation time varying between 1-
4 years. The data were cataloged and the final and proservation radiographs were
evaluated by three examiners, who followed the periapical evaluation index (PI) score.
The index rated the degree of cured and uncured teeth, indicating the percentage of
success or failure before the operative technique involving foraminal enlargement
during endodontic shaping. From the sample (N = 25), 23 elements obtained cure
outcome and only 2 were finished as uncured. The treatments with diagnosis of vital
pulp tissue showed 100% success. While the cases with present infection obtained
88.24% of success. In the cases of necrotic pulp with or without periradicular alteration,
the majority obtained final success. It can be concluded that the foraminal enlargement
technique allowed an expressive success rate, independent of the contamination or
not in the root canal system for the evaluated teeth.
