Deformed root surface groove refers to congenital dental dysplasia caused by excessive rolling of enamel forming device or local excessive proliferation deep into the dental papilla before calcification of dental tissue. It is clinically presented as a longitudinal fissure that runs through the crown to the root of the affected tooth. Such affected teeth are often removed due to poor treatment results. In recent years, with the continuous application of periodontal tissue regeneration and the continuous innovation of medical technology, most affected teeth can be preserved. It has been reported that root canal treatment combined with apical surgery and periodontal guided tissue regeneration can be used to treat deformed root surface sulcus and preserve the affected teeth[1]。 A patient with deformed root surface groove of upper anterior teeth was admitted to the Microscopic Root Canal Treatment Center of the Second Affiliated Hospital of Liaoning Medical College, and the report is as follows.
