BACKGROUND: The aim of this study was to evaluate the complications associated with the occurrence and treatment of impacted maxillary @entity235 . METHODS: This retrospective study was conducted on 533 Southern Chinese @entity1 and adolescents who attended the Paediatric Dentistry and Orthodontics Clinics and had at least one impacted maxillary @entity235 . The study material included all the documentation files and radiographs of these @entity1 . Complications that had been recorded in the clinical and surgical notes and that could be diagnosed from the available radiographs were noted. The data obtained were descriptively analyzed. RESULTS: The most frequently reported phenomenon associated with the occurrence of impacted maxillary @entity235 (prior to surgical treatment) was root resorption of an adjacent permanent tooth in 22 (4.1%) @entity1 . The most frequently reported sequelae observed after any surgical procedure was swelling of the soft tissues around the operation site which often persisted for 48h as seen in 76 (18.8%) @entity1 . Complications reported most commonly after any form of surgery included @entity548 : 7(1.7%), @entity1410 : 7(1.7%), post-operative @entity158 : 6(1.5%) and purulent discharge: 6(1.5%), post-operative complications in relation to surgical exposure and bonding of an attachment which included breakage of ligature wire: 5.7%; de-bonding of the attachment: 4.3% and inability to bond the attachment during surgery: 1.4% occurred rarely. CONCLUSIONS: The frequency of root resorption of teeth adjacent to an impacted maxillary @entity235 was low. Swelling of the soft tissue 48h post-operatively was the most commonly occurring complication after surgical intervention.
