Introduction: It is known that radiopacity is one of the important requirements for a dental material, since it allows the dental structures and adjacent tissues to be distinguished from the auxiliary material, facilitating the radiographic diagnosis. Therefore, with the introduction of new formulations of endodontic materials, it is essential that this property complies with current regulations. Aim: of this study was to evaluate the radiopacities of MTA Angelus white, MTA Repair HP and Biodentine cements and compare them with those of human dental structures, by digital radiography. Methods: Five specimens were made for each studied cement. Each sample was radiographed by the digital method, along with a slice of a healthy lower human molar tooth and an aluminum density scale (Al). For each set, three images were obtained and evaluated for densities using the histogram tool of the ImageJ software. In each evaluated structure a region of pre-defined interest was used and the densities were presented using means, standard deviations and medians. To assess the normality of the data and compare the radiopacity of the three cements tested, the Shapiro-Wilk and Kruskal- Wallis tests were applied, respectively. Results: Radiopacities equivalent to 2 mm of Al and 1 mm of Al, respectively, were observed for enamel and dentin. Both White MTA and MTA Repair HP cements presented radiopacity equivalent to 3 mm of Al. However, the Biodentine cement presented lower radiopacity than the other materials tested (2 mm of Al). Conclusion: It is suggested that both White MTA and MTA Repair HP presented radiopacities in accordance with the standards of the International Organization for Standardization 6876/2001 and American National Standard Institute number 57, in contrast to Biodentine, which demonstrated lower radio-density and not compatible with the regulation.
