Evaluation of the visibility of the materials used in furcation perforation in imaging devices

Abstract

Background: Variable radiographic techniques are used for postoperative evaluation of the materials used in furcation perforation. Since it is easily accessible clinically and the radiation dose which the patient is exposed to, is lower than the advanced imaging methods, intraoral imaging is applied. In cases that cannot be determined by 2D radiographs, cone beam computed tomography is more relevant because of the absence of superimpositions and allowing for multiplanar imaging. The aim of this study was to assess the diagnostic acceptability of the radiographic visibility of the materials used in furcation perforations and to find out which radiographic technique was efficient to view the materials. Methods: One hundred and twelve lower molar teeth were used according to the study criteria. Biodentin, BioAggregate, MTA and Endosequence were applied individually to the teeth, in order to repair the perforation zone. Periapical radiographs were obtained with Soredex Digora Optime with photostimulated phosphor plates. Other radiographic images were obtained using Planmeca Dixi 3 CCD, while CBCT images were obtained using Morita Veraviewepocs 3D R100. An endodontist and two dentomaxillofacial radiology specialists evaluated the images of CBCT and periapical radiographs. Teeth were evaluated randomly for the visibility of the repair materials in furcal perforations and scored. Results: MTA and Biodentine presented low image clarity while Bioaggregate and Endosequence had high image clarity. Morita Veraviewepocs 3D R100 depicted the highest sharpness, but no difference was observed between Soredex Digora Optime and Planmeca Dixi 3 devices. Conclusion: In the postoperative follow-up of the materials used in the treatment of furcation perforations, the usage of CBCT and the use of Bioagregate and Endosequence, which provide the best image clarity, has been suggested.
