Introduction. The anatomy and morphology of the roots and root canal systems of multi-rooted teeth, especially the molars, shows numerous variations. Preoperative radiography, in particular cone-beam computed tomography (CBCT), has exceptional significance in detecting anatomical variations and unusual root canal morphologies, which are extremely important to be familiar with in order to undertake successful endodontic therapy and minimize procedural errors. Outline of cases. This report presents cases of incidental diagnosis of an unusual root anatomy and root canal morphology of permanent molars in two patients. Diagnosis in the first case was made using orthopantomography and confirmed after extraction therapy. The second case reviled unusual root anatomy and root canal morphology of the permanent molar after preoperative CBCT imaging. Conclusion. Anatomical and morphological variations of roots and root canal systems can occur in any tooth. Clinicians should expect these variations, which should be thoroughly investigated when considering dental treatment.
