Abstract

Hyperdontia or supernumerary teeth without associated syndrome is a rare phenomenon, as supernumerary teeth are usually associated with cleft lip and palate or other syndromes such as Gardner's syndrome, cleidocranial dysplasia, and so on. Five patients with supernumerary teeth visited our department. They had no familial history or other pathology, certain treatment protocols was modified due to the presence of supernumerary teeth. Non-syndromic supernumerary teeth, if asymptomatic, need to have periodical radiographic observation. If they showed no variation as they impacted in the jaw, careful examination is necessary because they may develop into pathological status such as dentigerous cysts. The importance of a precise clinical history and radiographic examination for patients with multiple supernumerary teeth should be emphasized.

  Fig. 1 Case 1. A. Intraoral photograph shows a tooth-like structure with a blackish discoloration appeared to be embedded distal to the third molar. B. Lateral oblique radiograph reveals the presence of a partially impacted tooth having morphology similar to a molar distal to the third molar. The tooth is associated with a large radiolucency in the crown and a periapical lesion.

• 

  Fig. 2 Case 2. A. Intraoral photograph shows a supernumerary tooth, placed palatal and distal to the third molar. B. Panoramic radiograph shows a supernumerary tooth distal to the right maxillary third molar.

• 

  Fig. 3 Case 3. A. Intraoral photograph shows a carious lesion of the left mandibular first premolar, with the presence of root piece of the second premolar followed by two more premolar-like teeth in the lower left quadrant. On the right side, there are a total of 4 well aligned premolars. B. Panoramic radiograph shows a supernumerary tooth distal to the right maxillary premolars, two erupted supernumerary teeth on the right mandibular premolar area, and an impacted supernumerary tooth mesial to the left mandibular first molar.

• 

  Fig. 4 Case 4. A. Intraoral photograph shows three supernumerary teeth lingual and distal to the right mandibular premolars. B. Panoramic radiograph reveals an impacted supplementary tooth apical to the left mandibular second premolar. C. Intraoral periapical radiograph shows the presence of a dilacerated premolar-like tooth between the second premolar and the first molar.

• 

  Fig. 5 Case 5. A. Intraoral photograph shows a supplementary tooth distal to the left mandibular premolar and two supplementary teeth lingual and distal to the right mandibular premolars. B. Panoramic radiograph reveals an impacted supplementary tooth below the left mandibular canine and premolars.
