Abstract

Objective: To evaluate the internal adaptation of different milled post materials using microcomputed tomography.Materials and Methods: Forty mandibular first premolar teeth were distributed into four equal groups (n=10). Three groups in which different milled post materials were used in widely flared root canals: group CV; Custom made Vita Enamic posts, group CP; Custom made PEKK posts, group CF; Custom made fiber posts and one group in which ready-made fiber posts were used in normal root canal (group RF). All teeth received root canal treatment and were sectioned 1.5 mm above the cemento-enamel junction. The gutta-percha was removed from the root canals to a total depth of 9 mm from the cutting site. Thirty milled post-and-core were milled after direct scanning of the flared root canals and ten prefabricated fiber posts were used for the normally flared root canals. Cementation was done using self-adhesive, self-cure multilink speed resin cement. Cement thickness and voids volume was measured using microcomputed tomography scanning. Results: There was a significant difference in cement distance between groups at the different sites and sections (p<0.05). The mean ± standard deviation of cement distance was 154 ± 67 µm. There was a significant increase in buccal cement distance in the cervical and middle sections in the group (RF). There was no significant difference in voids volume between groups. Conclusions: Different CAD/CAM milled post materials fabricated from fiber, Polyetherketoneketone, and Vita Enamic presented adequate internal adaptation to flared root canals. The voids increased in the apical-coronal direction.
