Ample radiopacity in order to distinguish from the surrounding tissues is a desirable property of dental graft materials. A total of 15 bone graft materials’ (BGMs) opacities were analyzed in this study. Materials and methods: Graft materials were placed in the implant cavity (5 × 10 mm) in cadaver’s mandible respectively. Cavity was exposed by using periapical film and a dental X-ray machine at 70 kVp and 8 mA. The optical density of the radiographic images was measured with a transmission densitometer. One-way analysis of variance (ANOVA) was conducted for statistical analysis. Results: Among the materials tested, the most radiolucent bone grafts were Grafton and Allogenix with a statistical significance of p ≥ 0.05. 4Bone and Bego Oss exhibited the highest radiopacity with a statistical significance of p ≥ 0.05. Inadequate radiopacity of the dental graft materials may lead to confusion among clinicians in the radiographical follow-up. Among 15 BGMs tested, only three had higher density than bone tissue. Conclusion: The radiopacity of the BGM was found to be higher than bone at only three of them.
