Abstract :

AIM: To compare the homogeneity of thermoplasticized gutta-percha and cold-flowable gutta-percha after obturation.

MATERIALS AND METHODS: Forty single-rooted teeth were selected and the canals were shaped with ProTaper Next rotary files and irrigated with 3% sodium hypochlorite and 17% EDTA. Group A - obturated with Obtura II and AHplus sealer, and Group B- obturated using GuttaFlow. The roots of the teeth were sectioned at five levels and were observed under a stereomicroscope at 40 × magnification and the images were analyzed.

RESULTS: The number of voids were more in the Group B –GuttaFlow (56%) when compared to Group A- Obtura II (15%). The area of the voids in the GuttaFlow was small and were seen mostly in the core, whereas the area of the voids in Obtura II was large but were seen equally in the core and at the periphery.

CONCLUSION: The Obtura II and GuttaFlow showed acceptable adaptation to the canal walls but Obtura II has more homogeneity when compared to GuttaFlow.
