A 20-year-old male reported to our outpatient department for correction of his misaligned teeth. Familial, medical and dental history was non-contributory. General examination and extra-oral examination showed no abnormality. Dental examination revealed the absence of six permanent teeth besides the third molars, retention of two deciduous teeth and presence of two supernumerary incisors (in between Teeth 11 and 22).

OPG revealed the intraosseous presence of teeth belonging to the permanent dentition and supernumerary teeth. Twelve impacted supernumerary (SN) teeth resembling premolars and radiographically showing various stages of root completion were seen [Figure - 1].

Based on the dental findings and the absence of any associated disorder or syndrome, we arrived at a diagnosis of non-syndromic multiple supernumerary teeth.

   Discussion Top

Supernumerary teeth or hyperdontia are those that are additional to the normal complement of teeth. [1] Very rarely, three or more supernumerary teeth are seen in the same individual. [2] Such multiple supernumerary teeth are usually associated with developmental disorders or syndromes like cleidocranial dysplasia. [3] Occurrence of multiple supernumerary teeth in the absence of any associated syndrome or condition is very uncommon. In such non-syndromic cases, mandibular premolar region is the preferred site of occurrence, [4] a pattern observed in nine of the 14 supernumerary teeth in our case.

Supernumerary teeth are classified based on their morphology and location in the dental arch. All the 14 supernumerary teeth in our case belonged to the supplemental variety, 12 of them resembling the premolar and two resembling the incisor.

Supernumerary teeth are usually impacted and mostly inverted in position. [5] Twelve of the 14 supernumeraries in our case were impacted and all the supplemental teeth were oriented normally.

As observed in the literature, [6] clinical problems such as impedance of eruption and displacement of permanent teeth were seen in our case too.
