Properties of two Endodontic Sealers: an in Vitro Study

Objectives: One of the most important factors that affects the endodontic treatment outcome is root filling with no voids. The aim of this study was to evaluate and compare void ratio of resin based sealer with void ratio of calcium silicates based sealer in root canal during obturation with gutta-percha cone.
Methods: 36 manbibular premolars of adults extracted teeth due to orthodontic treatment. These teeth were went through endodontic procedure include pulp accessing and cannal shaping. After preparation, sample were divided into 2 group: Group 1 teeth were obturated with gutta-percha cone and AH Plus sealer, group 2 teeth were obturated with gutta-perrcha cone and Ceraseal sealer. After all sealers were set, teeth were put in resin mold and horizontal section at 3 mm and 6 mm from apex. All the sections were photographed and picture were transfer to computer and the void ratio were calculated.
Results: Void ratio in the canal between resin based sealer and calcium silicates sealer at 3 mm and 6 mm from apex show no statistical difference.
Conclusions: Both endodontic sealers showed similar sealing ability at 3 mm and 6 mm from apex.
