Abstract
INTRODUCTION:
In periapical surgery, the absence of standardization between different studies makes it difficult to compare the outcomes.
OBJECTIVE:
To compare the healing classification of different authors and evaluate the prognostic criteria of periapical surgery at 12 months.
MATERIAL AND METHODS:
278 patients (101 men and 177 women) with a mean age of 38.1 years (range 11 to 77) treated with periapical surgeryusing the ultrasound technique and a 2.6x magnifying glass, and silver amalgam as root-end filling material were included in the study. Evolution was analyzed using the clinical criteria of Mikkonen et al., 1983; radiographic criteria of Rud et al., 1972; the overall combined clinical and radiographiccriteria of von Arx and Kurt, 1999; and the Friedman (2005) concept of functional tooth at 12 months of surgery.
RESULTS:
After 12 months, 87.2% clinical success was obtained according to the Mikkonen et al., 1983 criteria; 73.9% complete radiographichealing using Rud et al. criteria; 62.1% overall success, following the clinical and radiographic parameters of von Arx and Kurt, and 91.9% of teeth were functional. The von Arx and Kurt criteria was found to be the most reliable.
CONCLUSION:
Overall evolution according to von Arx and Kurt agreed most closely with the other scales.
