Features of radiopacity of MTA-containing cements according to sighting intraoral radiography and CBCT

Abstract

Controlling all stages of an endodontic treatment using intraoral periapical radiography and computer cone-beam tomography (CBCT) has become a common practice in dentistry. The emergence of new MTA materials on the dental market based on Portland cement raises the issue of their diagnostic abilities on radiographs and CBCT scans. The radiopacity of the materials is insured by the addition of various elements into its composition. Depending on the manufacturer, these additives may vary, which can lead to changes in the radiopacity. The aim of the study was to determine the visualization of MTA-containing cements on periapical radiographs and CBCT images when closing a perforation. On the extracted teeth, holes imitating perforations were made and filled with MTA containing cements, commonly used in Russia. The X-rays and CBCT scans were analyzed and the cements radiopacity assessed. High contrast of the MTA containing cements used in this study on CBCT images allows a highly potent diagnosis, which can be effective in difficult clinical situations.
