ABSTRACT
Introduction: The use of fiberglass posts is the current method most used for post-endodontic reconstruction. However, its adhesion remains unpredictable due to the limited control of its cementing technique. Bulk-fill resins reveal values of flexural strength similar to dentin and their use in post-endodontic reconstruction could be a viable and conservative alternative.
Objective: Compare three post-endodontic reconstruction techniques by measuring their resistance to eviction forces, classifying the type of fracture and adhesive failure, evaluating their cost and time of work.
Material and methods: 18 samples are divided into 3 groups: group 1: post plus cement of 1 step, group 2: post plus cement of 3 steps and group 3: post-endodontic reconstruction with bulk-fill resin.
Results: In the evaluation of the force to the eviction, no statistically significant difference was found in the 3 groups. Regarding the behavior and adhesive failure, a significant difference was found p ‹ 0.001, favoring groups 2 and 3, due to its adhesion in the root portion. The type of fracture was restorable for the 3 groups. Regarding time and cost, they were significantly lower for group 3.
Conclusion: In our study there was no significant difference in the force to the eviction in the three groups, however there was in the behavior, adhesive failure, cost and time, favoring mainly the group 3. The technique of reconstruction with resin can be a predictable technique, Sufficiently resistant, conservative, fast and of lower cost.
