Evaluation of the radiopacities of four different root canal sealers by digital radiographic technique

26747

OBJECTIVE: The aim of this study was to compare the radiopacities of four different root canal sealers and gutta-percha. MATERIALS AND METHOD: AH Plus, iRootSP, MTA Fillapex and Sealapex as root canal sealers and gutta-percha cones were tested. Standardized discs of the root canal sealers and the gutta-percha were prepared. Digital radiographs of the discs and an aluminum penetrometer were obtained by using a phosphor plate. The radiographic density of the sealers and the gutta-percha were measured by using the digital radiographic system’s own measurement tool, and equivalent aluminum thicknesses were determined by using an image editing software. Differences among radiopacities of the root canal sealers and the gutta-percha were analyzed using One-way ANOVA and Tukey post-hoc tests. RESULTS: Aluminum thickness equivalents of the radiopacity values of the samples, in descending order, were: AH Plus, Sealapex, iRootSP, MTA Fillapex and gutta-percha. No significant difference was found between the radiopacity values of AH Plus and Sealapex (p 0.05). There were statistically significant differences between these two groups (AH Plus and Sealapex) and all other experimental groups (p 0.05). CONCLUSION: AH Plus and Sealapex exhibited the highest radiopacity values among tested groups. In addition, all tested materials fulfilled the minimum standard value requirements suggested by International Standardization Organization and American National Standards Institute.
