Abstract

Aim: To evaluate, in vitro, the residual dentin thickness in the palatal root of premolars after preparation of the post space with Post Preparation drill and to compare with the Gates-Glidden and Largo drills by means of cone beam computed tomography. Methodology: 21 premolars were selected and randomized into 3 groups: G1 - Post-preparation drills; G2 - Gates-Glidden drills nº 2 and nº 3; G3 - Wide Drills nº 1 and nº 2. The residual dentin thickness in seven cuts for the mesial, distal, buccal and palatal points was measured in three stages: initial (not prepared), after instrumentation for apical file nº 35 and after preparation powders with Kodak CS 9000C 3D Extraoral Imaging System and CS 3D Image v. 3.4.3. Software. The root canal area was analyzed in three stages using VRMesh Reverse v. 7.6.1. Software. Statistical significance was set at 5%. Linear and area measurements data were analyzed using the Kruskal-Wallis test. Results: Post-preparation drills performed similarly to other drills in linear and area analysis. Conclusion: Post-preparation drills showed similar performance to Gates-Glidden and Largo drills in the analysis of residual dentin thickness for the preparation of the pin space.
