  Abstract 

Supernumerary teeth or Hyperdontia is reported to be more common in the permanent dentition than deciduous dentition. The incidence of hyperdontia is found to be in the range of 0.1-3.8%. The timely diagnosis and therapeutic interventions may avoid the unwanted complications.

Keywords: Hyperdontia, multiple supernumerary teeth, non-syndromic hyperdontia

A 23-year-old male reported with chief complaint of pain in mandibular third molar region on both sides. On clinical examination, there was no evidence of any pathology except for vertically impacted mandibular third molar with crown seen partially on left side [Figure 1]. The orthopantomogram (OPG) showed multiple supernumerary teeth in jaw bones being 10 in number located in maxillary and mandibular jaws bilaterally [Figure 2]. The teeth were embedded in the jawbone, and hence the patient was not aware on these. There was no clinical evidence of their presence in oral cavity, except that patient had mild crowding in upper and lower anterior region.

On thorough general examination, no abnormality could be detected. The parents of the patients were non consanguineous and normal. The patient had two siblings who were normal; the OPGs were also taken for them, which did not show any abnormality.

The syndromic associations of supernumerary teeth are commonly found with Gardner's syndrome, oral clefts, Ehlers-Danlos syndrome, Fabry's syndrome, ectodermal dysplasias, and cleidocranial dysostosis. [1],[2],[3],[4],[5] Nonsyndromic occurrence of supernumerary teeth is a rare phenomenon, earlier studies showed prevalence of 1-3.8% with predominance in the males and in permanent dentition. [2],[6] The maxillary incisor and molar region is the site of predilection for the occurrence of supernumerary teeth followed by mandibular molar, premolar, and incisor region. [2],[6]

The complications associated with presence of supernumerary teeth include crowding; inflammations; teeth displacements; failure or delay in eruptions; dental caries or loss of vitality of tooth; tooth resorption; interferences in implant placement; bone grafting and orthodontic treatment; and pathologies such as dentigerous cyst, adenomatoid odontogenic tumours, radicular cyst, odontomas, etc. [2],[4],[5],[6]

Asymptomatic supernumerary teeth are at more risk to the pathologies, the timely diagnosis and therapeutic interventions may avoid the unwanted complications. [1],[4],[6]
