Resumen

GALLARDO, Paulo; CORRAL-NUNEZ, Camila; OSORIO, Sylvia  y  ESTAY, Juan. “Radiopacity of Resin Cements Evaluated with Digital Radiographic Technique”. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2019, vol.12, n.2, pp.77-80. ISSN 0719-0107.  http://dx.doi.org/10.4067/S0719-01072019000200077.

Objective:

Compare the radiopacity of different resin cements and verify their compliance with the requirements of ISO regulations.

Material and method:

Samples -10 mm in diameter and 1 mm thickness- of the resin cements RelyX U200 (3M ESPE), Calibra (Dentsply Sirona), Universal Calibra (Dentsply Sirona) and Bifix SE (VOCO) were prepared. Radiographies of the samples with a stepped aluminum wedge were obtained. For each sample, the grayscale and mm of Al values were calculated. The data were analyzed to compare the radiopacity of the materials and to contrast them with the requirements established by ISO standards.

Results:

The equivalent radiopacity in mm of Al in descending order was 2.84 ± 0.18 for Calibra, 2.37 ± 0.15 for Bifix SE, 2.26 ± 0.14 for Calibra Universal and 1.67 ± 0.07 for RelyX U200. These values exceed the value required by ISO 4049 standard. Statistically significant differences were established between the cements.

Conclusion:

There are differences in the radiopacity of the resin cements studied. However, all the cements complied with ISO 4049 radiopacity standards.
