- Abstract
Objective: The aim of this study was to evaluate the effectiveness of heat only and heat with vibration obturation techniques in obturating simulated lateral canals within a root canal system, by measuring the percentage of gutta-percha (GP) penetration length at the coronal, middle, and apical thirds of the root canal. Methodology: Seventy mandibular second premolar teeth were prepared with K3 rotary file and randomly divided into two groups of 35 each. Three simulated lateral canals with the diameter of 0.15 mm at the coronal, middle and apical thirds on the distal root surfaces were created. Group G, was obturated using system B (heat only). Group G2 was obturated using DownPak (heat and vibration); AH 26 sealer was used in both groups. Radiographs were taken for all specimens at the bucco-lingual direction and all images were transformed into a digital format. Length of the simulated lateral canals and GP penetration inside the lateral canals (coronal, middle and apical thirds) were measured by VixWin Pro 2000 software and then GP percent ages inside the canals were calculated. Data were analyzed using one-way ANOVA test. Results: Mean percentage length of GP in the lateral canals of the apical third level was significantly higher (P < 0.05) in those obturated by heat associated with vibration technique than lateral canals obturated by heat only. Conclusions: Heat with vibration technique was found to be superior to heat only technique for obturation especially at the apical third level of root canal.
