Abstract

AIM:

The aim of this report is to present a clinical case of impaction of a maxillary left central incisor in a mixed dentition caused by the presence of an odontoma as well as a review of the pertinent dental literature.

BACKGROUND:

Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiologic development. A delay in time between the exfoliation of a deciduous tooth and the eruption of its permanent successor may be related to a disorder known as dental retention. This occurs when tooth eruption does not occur within a normal time frame, the tooth is not present in the dental arch, and there is no potential for eruption due to the presence of a completely formed root or when the homologous tooth has been erupted for at least six months with complete root formation.

REPORT:

A 10-year-old boy in the mixed dentition stage presented with an impacted maxillary left central incisor due to the presence of an odontoma. Treatment included the surgical removal of the lesion and the follow up of the spontaneous eruption while a partial fixed appliance was used to recover the space of the missing tooth. Since spontaneous eruption failed to occur within the expected time frame, surgical exposition of the crown and bonding of an orthodontic appliance for traction was done to facilitate eruption.

SUMMARY:

The incisor was integrated to the dental arch without any root or periodontal sequelae. The treatment was considered a success, since both health and aesthetics of the smile were recovered. The importance of the clinical and radiographic diagnosis of the retention of a permanent tooth associated with a pathological entity should be emphasized. The participation of a multidisciplinary team to accomplish the appropriate treatment of such patients is extremely relevant because of the esthetic and functional ramifications of a missing anterior tooth as well as the psychological well-being of the individual.
