Dental elements can be maintained when the endocrine retreatment is adequately indicated. The growth of endodontic techniques and materials has minimized the indication of surgical procedures even for teeth with intracanal posts. A year-old male patient related uncomfortable sensation and swelling under his upper lip associated with maxillary right central incisor tooth. After radiographic examination, the presence of a smoothly tapered post and an overextended root canal filling associated with a periapical radiolucency and radiolucency on the distal part of the coronal third of the maxillary right central incisor tooth was discovered.
The mesial margin of the crown did not fit well. Understanding the patients, treatment- and tooth-related prognostic predictors can assist the clinicians in appropriate case selection for apical surgery against treatment alternatives.
Teeth treated in conventional ways, which presents persistent periapical lesion, may have retreatment as the first therapeutic alternative. In particular, accidents during conventional treatment may have the negative effect over success, contributing to infection establishment in inaccessible apical areas, requiring surgical intervention [ 1 , 2 ].
Failure factors in root canal conventional treatment are frequently related to the presence of residual bacteria persistent infection or reinfection in a previously disinfected canal secondary infection [ 3 ]. Scientific evidence indicates that some factors may be associated with the unsatisfactory outcome of well-treated cases. They include microbial factors, comprising extraradicular and intraradicular infections, and intrinsic or extrinsic nonmicrobial factors [ 4 ].
Parendodontic surgery comprehends a set of procedures recommended in periapical diseases treatment when traditional endodontic therapy does not obtain favorable outcomes. We present a case of periapical lesion removal and the third apical sealing to allow soft and hard tissue regeneration [ 5 ]. A year-old male patient was referred to the Department of Conservative Dentistry and Endodontics with pain and labial swelling in the upper anterior region. A patient gave a history of trauma to front teeth more than 11 years ago.
