RESUMO

The aim of this study was to test ín vítro the apical sealing ability of endodontically treated human teeth prepared with intentional foramen enlargement. The root canals were prepared by conventional technique and filled by the lateral condensation with gutta-percha points and Endomethazone sealer. The teeth were coated with nail varnish layers, except the apical 2 mm, then immersed in black India ink under vacuum conditions during 10 minutes and stored for 7 days at 37º C. The specimens were rinsed under tap water and the varnish removed. The roots were subsequently cleared and examined at 15 magnification with a stereomicroscope. The apical sealing ability was determined by penetration of ink beyond the end of the preparation. Data were analyzed statistically using the Student s test. The level of significance was set at p = 0,05. The results obtained indicated that there is no difference in the apical sealing quality of endodontically treated teeth prepared with or without foramen enlargement
