摘 要：BACKGROUND Fused teeth usually involve several complications,such as the development of caries in the groove between fused crowns,tooth impaction,diastemas,aesthetic and periodontal problems,and pulpal pathosis,due to the complex anatomical structure of fused teeth.A thorough diagnosis is paramount to forming an accurate treatment plan and obtaining a favourable *** the advent of cone-beam computed tomography(CBCT),accurate 3-dimensional images of teeth and their surrounding dentoalveolar structures can now be readily obtained,and the technology can accurately provide a minimally invasive approach to acquire detailed diagnostic ***,we utilize CBCT data herein to generate a digital model for the infected region in a patient,and this model enables us to better plan the management of his *** SUMMARY This report details the diagnosis and endodontic treatment of a rare case involving a fused maxillary second molar and two paramolars with apical *** patient experienced pain upon biting and cold sensitivity in the area of the maxillary left *** caries or other defects were identified in these teeth,and a normal response to a pulp electric viability test was *** the aid of CBCT and digital model technology,we initially suspected that the infection originated from the isthmus between the maxillary second molar and two ***,we only treated the isthmus by an endodontic approach and did not destroy the original tooth structure;furthermore,the vital pulp was retained,and good treatment outcomes were observed at the 24-month *** This finding may provide new insights and perspectives on the diagnosis and treatment of fused teeth.
