ZOFFOLI, Juliana de Oliveira; ABAD, Ernani da Costa; ALMEIDA, Bernardo Mattos and ARMADA, Luciana. Evaluation the adaptation of guta-percha in apical segment of long oval canals. Rev. Bras. Odontol. [online]. 2013, vol.70, n.2, pp. 148-151. ISSN 1984-3747.
The present study aimed to evaluate in vitro the degree of adaptation of gutta-percha in the apical segment of the long oval canals first 40 premolars, filled by lateral compaction technique of gutta-percha (TCL) and Schilder (TS). Cuts at 1, 3 and 5 mm below the apex perpendicular to the long axis of the tooth surfaces revealed that analyzed with stereomicroscope and images evaluated through software. The average area of the apical third not filled with gutta-percha to the 1 mm group 1 = 3 8.72% and G roup 2 = 2 2.64%, the 3 m m g roup 1 = 3 0.32% a nd G roup 2 = 15.80% , the 5 mm group 1 = 57.38% and group 2 = 26.42%. Schilder's technique was more effective.
