Authors:

ABSTRACT

Aim

This paper reported a rare case of hyperdontia in a child of 10 years who revealed a mixed dentition and a light mental
retardation.

Methods

The therapeutic approach has been based on interdisciplinary cooperation between the
pediatric dentist, orthodontist and oral surgeon. TC-Dentascan, with a panoramic and occlusal radiographs revealed the presence of two
supernumerary teeth in the premaxillary region and clinical examination showed an abnormality of dentoalveolar complex. Both
impacted supernumerary teeth were extracted under general anesthesia. Clinical examination revealed that they appeared two
premolars in shape with fully formed crowns and partly formed roots.

Results

Three months after the extraction of supernumerary
teeth there was a spontaneous eruption of permanent central incisors and left lateral incisor.

Conclusion

The authors emphasized
the importance of removal of supernumerary teeth to eliminate the cause of a delayed eruption of permanent teeth.
