Abstract

Aim: To assess the effect of different activation techniques on the area of sealer penetration after using different sealers and different obturating materials.
Materials and Methods: Forty single rooted mandibular premolars are collected and were prepared with Protaper next up to size x4. Teeth were divided into 2 groups according to activation technique, each containing 20 teeth. Group (1): manual activation, Group (2): laser activation. Each group was subdivided into 2 groups according to sealer and obturating material, each containing 10 teeth. Subgroup (A): teeth were obturated with Adseal resin sealer mixed with methylene blue dye and Gutta Percha points, Subgroup (B): teeth were obturated with Ceraseal Bioceramic sealer mixed with methylene blue dye and C-Points. The teeth were sectioned at 3 mm and 6 mm from the apex and examined with Confocal Laser Scanning Microscopy.
Results: Diode laser activation and Bioceramic sealer+C-Points have significantly higher sealer penetration area than manual activation and Adseal resin sealer+Gutta percha points.
Conclusion: Diode laser activation has significantly more area of sealer penetration than Manual activation method. Also, Bioceramic sealer+C-Point has significantly higher area of sealer penetration compared to Adseal resin sealer+Gutta Percha points.
