Avaliação de tratamentos endodônticos com realização de ampliação foraminal.

Abstract

This work aimed on evaluating, through X-ray, both the evolution and the index of success of the endodontic treatment technique which makes use of apical foramen enlargement. Among 121 archived patient records, 64 met all the criteria to be taking part in the study and were selected for it. From the 64 patients, 15 patients attended to the meetings to participate in the study. All the patients have undergone both clinic and X-ray exams, in order to make possible the analysis of every case. Data were catalogued and both final and monitoring X-Rays (1 – 4 years) were submitted to an evaluation from three different examiners, who followed the periapical index scoring (PAI). Such index evaluated the degree of cured and non-cured teeth indicating the percentage of success or failure of the foramen enlargement surgery technique. From the sample (N = 15), 11 elements had cure outcomes, 3 finished as not cured and 1 element had to be extracted because the tooth suffered a crown fracture. Treatments with diagnosed vital pulp tissue presented 100% of success. Meanwhile, cases in which infection was present had 57.14% of success. Among the cases with necrotic pulp, with or without periapical alteration, the greatest part obtained final success. It could be concluded that the foramen enlargement technique permitted an expressive index of success regardless the contamination or not of the root canal system in evaluated teeth, making possible their functionalities to be kept.
