Evaluation of sealing ability and retrievability of GuttaCore obturating material (An in vitro study)

Abstract

ur study was conducted to evaluate the sealing ability and retrievability of GuttaCore obturating material and comparing it with warm vertical compaction technique. Sealing ability was evaluated using dye penetration method (clearing method). Retrievability, with different solvents, was evaluated by measuring the percentage of remaining obturation material and the time required for retreatment process. The total number of samples (n=80) were classified into two main groups (I and II) (n=40) according to the obturation technique used. Each main group was subdivided into two subgroups according to evaluation method: Subgroup 1 (n=10) where sealing ability was evaluated and subgroup 2 (n=30) where retrievability of the filling material was evaluated. Subgroup 2 was further subdivided into three subdivisions (N, C & E) according to the solvent used during retreatment (no solve
