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.
