most mandibular second molars have one and two canals in distal and mesial roots, respectively. this report represents four cases of mandibular second molars with a single mesial and two distal root canals with two different canal configurations. after access cavity preparation, two teeth had one distal and two mesial orifices, whereas in the two other teeth one mesial and two distal orifices w...

OBJECTIVES Cone-beam computed tomography in dentistry can be used in some countries by other dentists than specialists in radiology. The frequency of buying cone-beam computed tomography to examine patients is rapidly growing, thus knowledge of how to use it is very important. The aim was to compare the outcome of an investigation on the use of cone-beam computed tomography in Sweden with a pre...

AIM To report the use of cone beam computed tomography in the assessment of external cervical resorption lesions. SUMMARY Asymptomatic external cervical resorption lesions were diagnosed radiographically in two patients. Clinical examination in both cases was unremarkable. Cone beam computed tomography scans revealed the true nature of the lesions in three dimensions. The resorption lesion in...

surgical procedure for removal of impacted teeth is a challenge for clinicians as it involves accuracy in the diagnosis and localization of the dental elements. the cone-beam computed tomography (cbct), compared to the conventional radiography, has a greater potential to provide complementary information because of its three-dimensional (3d) images, reducing the possibility of failures in surgi...

mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. damage to the mandibular canal can occur during implant surgery. depending...
