Abstract

Introduction

The visualization and understanding of the details of the root configurations and root canal structure are essential prior to root canal treatment. This study aimed to identify key indicators of pronounced root divergence between the distobuccal and distolingual roots in mandibular first molars by highlighting common features observed in panoramic radiographs. These indicators can help predict the likelihood of encountering significant root divergence before initiating endodontic treatment.

Case Presentation

We present three cases in which panoramic radiographs displayed imaging features characteristic of root resorption in the distal root of the mandibular first molars. However, subsequent periapical radiographs in case 1 and cone-beam computed tomography images in cases 2 and 3 revealed that the mandibular first molars were in normal condition, with pronounced root divergence but no evidence of root resorption.

Conclusion

Panoramic radiographs depicting mandibular molar roots with a resorptive and unclear appearance may indicate the presence of severe root divergence. In such cases, we strongly recommend additional cone-beam computed tomographic imaging to ensure precise diagnosis and facilitate optimal treatment planning for endodontic procedures.
