SUPERNUMERARY TEETH-REVIEWOFPREVALENCE AND CHARACTERISTICS. PART I.

Supernumerary teeth are defined as an excess in the number of teeth when compared to the normal dental formula. Supernumerary teeth are not an uncommon anomaly with a prevalence range of 0.15 to 3.8 percent. They occur more frequently in the permanent than in the primary dentition and in males more frequently than in females. They can occur almost anywhere in the mouth and may exist unilaterally or bilaterally, but the upper incisor region has been reported as the region most frequently affected by supernumerary teeth.Supernumeraryteeth can be classified according to form or shape, location, time of appearance, extent of eruption and position of supernumerary teeth, and severity of the condition.They present with different severities, but multiple supernumerary teeth are found to be rare especially of cases with more than 2 supernumeraries.
