Abstract

Aim: To measure the percentage of canal filled area in long oval canals obturated with thermoplasticized gutta-percha techniques. Methodology: Fifty four mandibular incisors were selected after bucco-lingual and mesio-distal radiographs showed at 5 mm from apex an internal long: short diameter ≥2. They were instrumented with Protaper Universal and divided in two groups of 27. Group 1 was obturated with Thermafil Obturators and group 2 with Beefil 2in1. Two horizontal sections were cut at 5 and 7 mm from the apex and photographed in a stereomicroscope. The area of the canal and filled canal in cross-sections were measured with AutoCad and the percentage of gutta-percha and sealer in the canal was calculated. Results: Both systems achieved high percentage of filled canal, group 1 96.8% and group 2 98.9%. No significant difference was found between the two groups (P = 0.110). The percentage obtained at 5 and 7 mm from the apex in both groups showed no significant difference (Thermafil P = 0.285; Beefill 2in1 P = 0.159). Conclusions: The percentages of gutta-percha-sealer-filled canal were high and low percentage of voids was found.
