Among 63,029 patients admitted to Department of Oral Radiology, University of Oslo, 900 had a total of 1153 supernumerary teeth located to the premaxillary region. Characteristics of the supernumeraries were predominance in males, predominance in the permanent dentition, predominant location in the central incisor region, and predominant position palatally to the dental arch, vertically oriented, half of them inverted. Interference with the normal dentition included malposition, diastema, maleruption, and resorption. Sequelae included widened follicular space, dentigerous cyst formation, dental pulp necrosis, pulp canal obliteration, root resorption, and ankylosis. Nearly 60% of the patients had radiographic or clinical signs of interference with the normal dentition or of associated complications.
