Abstract: Objectives This study evaluated the radiopacity of seven commercial root canal posts. Methods Digital radiographs of the seven commercial posts and of the same commercial posts and four artificial aluminum posts inserted in lower canines were obtained with a CCD-based digital sensor. The radiopacity of the posts was expressed as mm aluminum/mm material (mmAl). Subsequently, the radiographs were presented to five trained evaluators who were asked to rank their acceptability scores as not acceptable, acceptable, or excellent. Results Analysis of variance revealed significant differences in radiopacity among the posts (P\0.05). The radiopacities of zirconium and titanium posts were significantly higher than those of fiber posts (P\0.05). The minimum aluminum thickness for acceptance in the root canals was 1.2 mmAl. Conclusions All of the examined posts presented satisfactory radiopacity for clinical application. © Japanese Society for Oral and Maxillofacial Radiology and Springer Japan 2013.
