Multiple supernumerary teeth in non-syndromic patients: report of 5 clinical cases

A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. They have been described in both primary and permanent dentition. Multiple supernumerary teeth are rare in non-syndromic patients. The purpose of this study was to evaluate non-syndromic patients with five or more supernumerary teeth, by general and local clinical examinations, periapical, occlusal and panoramic radiographs. The patientsÆ data were collected regarding to the number of supernumerary teeth, location, shape, position and association to pathological lesion. Thirty-five supernumerary teeth were found, 17 in the mandible and 18 in the maxilla. In the lower arch, 16 supernumerary teeth were localized in the premolar region and 1 in a disto molar region. However, in the upper arch, there were 7 in the premaxilla, 6 in the premolar and 5 in the disto molar region. From the total, 28 were supplemental and 7were found in a rudimentary shape. Completing the observations, 29included teeth were detected and one showed a radiolucent area that suggested a dentigerous cyst. Six other teeth showed a widened follicular space. One of the upper molar from the normal series was related to an odontoma. We could conclude that mandible and maxilla were equally affected and most of the teeth morphology was similar in size and shape to normal tooth (supplemental). Twenty-nine teeth were impacted; however few have caused pathologies.

Root development in relation to impacted mesiodens.

Presented here is a case of 7 years 6 month old child with an apically impacted mesiodens in relation to the developing root of right upper central incisor. The removal of mesiodens was deferred in order to avoid disturbance in the natural development of the upper central incisor. Serial X-rays are presented and case is discussed.
