Introduction: This study aimed to assess the periapical status and the quality of root canal filling of endodontically treated teeth from cone-beam volume tomography (CBCT) images.
Materials and Methods: Of 66 teeth (124 root canals) that received root canal treatment, the quality of the root canal filling as well as the periapical status were assessed using cone-beam volume tomography (CBCT). Radicular obturation on an X-ray image was defined as satisfactory if it is 0-2 mm from the radiographic apex without voids. On CBCT scans, the apical end of the canal has replaced the radiographic apex.
Results: The present study showed, according to the periapical status, 87.9% (n = 109) of the canals exhibited a periapical lesion. The 1, 2, and D scores of the CBCT PAI were more met with respectively 46, 19.4%, and 8.9%. The association between the lengh of root canal filling and the presence of apical radiolucency showed a significant relationship (p = 0.02). The presence of apical radiolucency is also very significantly associated with the inadequate density of root canal fillings (p = 00003).
Conclusion: The present study confirms, by CBCT, that the presence of periapical lesions was associated with poor quality obturation technique.
