Management of Different Types of Root Resorption Affecting Traumatised Permanent Maxillary Incisors-A Case Report

Managing defects caused by pathological root resorption in permanent teeth can be challenging. If not diagnosed and treated efficiently, progressive root resorption can result in the loss of a tooth. This paper reports the consequences and treatment of poorly managed dental trauma 3 years ago affecting maxillary central and lateral incisors of an 11-year-old male child. Intraoral periapical radiographs revealed resorption defects involving the cervical, middle and apical thirds of Tooth Numbers 12, 11, 21 and 22 (FDI numbering system). A blunderbuss canal with a wide open apex was also noted in relation to Tooth Number 22. Resorption defects involving the pulp canal space and calcification of the pulp were also noted in relation to Tooth Numbers 21 and 12, respectively. This was confirmed by a CBCT scan. A diagnosis of infection-related root resorption, invasive cervical root resorption with pulp canal calcification and internal root resorption was made in relation to Tooth Numbers 11, 22, 12 and 21, respectively. The cervical defect in relation to Tooth Number 22 was surgically debrided and filled using MTA. Nonsurgical endodontic treatment was performed in relation to Tooth Numbers 11 and 21, and apexification was performed in Tooth Number 22. Bioceramic materials like MTA and Biodentine were used to seal the resorption defects as well as obturate the entire root canals of the affected teeth. On 36 months' follow-up, the treated teeth were clinically asymptomatic, showed healing radiographically, and there was no further progression of root resorption. The outcome of this case emphasises the importance of timely management and appropriate clinical care in all traumatic dental injuries. The role of bioceramics in managing root resorptions seems to be promising.
