Aim: The application of cone-beam computed tomography (CBCT) in the management of calcified root canal system.
Background and objectives: Dental trauma to the permanent dentition can lead to various clinical complications and its management may be considerably challenging for a dental clinician. One such complication is intracanal obliteration. Root canal calcification occurs commonly following traumatic injuries to permanent teeth in approximately 4–24% of cases which is characterized by the apparent loss of the pulp space radiographically and discoloration of the clinical crown. These teeth provide an endodontic treatment challenge in locating the root canal orifice and negotiating the canal to its full working length. Iatrogenic errors such as instrument separation and root perforation are more prone to occur in such cases.
Case description: Two patients were reported to the department with the chief complaint of discolored teeth in the upper front tooth region. On radiographic examination, pulp canal obliteration (PCO) was identified and the two cases were managed successfully with the help of CBCT.
Conclusion: With the application of CBCT as a guide, it is helpful in orienting the burs angulation within the pulp chamber with fewer chances of iatrogenic injury.
Clinical significance: Cone-beam computed tomography (CBCT) is considered the third eye of an endodontist which provides images in sliced sections in all the three planes without overlapping the adjacent structures and it facilitates the identification of the canal orifices, canal directions, degrees of obstruction, and also their dimensions.
