Introduction: The aim of the present study was to compare three techniques of sealer insertion in flat canals. The conventional technique where the sealer is inserted with the master cone was compared to 2 experimental groups, Irrisonic tip and Easyclean file in reciprocal movement. Methods: Forty-five mandibular incisors with flat anatomy of root canal (RC) were selected for this study. The RC were enlarged up to the R40 Reciproc file size. Next, the samples were divided into 3 groups (n = 15) in accordance with the insertion sealer techniques. For obturation, in all groups, the Touch’n Heat was used. The sections at 2 and 4mm from foramen were obtained and they were examined in a stereoscopic with a 40-times magnification. In the sequence, images were taken with a digital camera and the total area of the RC, as well as the voids and areas filled with gutta-percha and sealer were measured with the Axion Vision LE software. Results: At the levels 2mm (p=0,131) and 4mm (p>0,05) there was no difference among the groups in relation to the void areas. The void areas were compared also between the levels 2mm and 4mm and there was no difference present in any tested group. (EasyClean File p=0,309, Master Cone: p=0,164; Irrisonic: p=0,867). Conclusions: The Irrisonic ultrasonic tip and Easyclean files could not provide a better filling result than the conventional technique.
