Abstract
|
|
|
|
The supernumerary premolars account for 4%-9% of all supernumeraries and reported prevalence is 0.01%-1.00%. Multiple supernumerary teeth can be seen in syndromic phenotypes. But, only 2% of supernumerary premolars exhibited any pathological changes. Most of them cause interference with normal occlusal development that makes maintaining the disabled patients’s oral hygiene difficult. It is recommended to delay the timing of extraction until the full permanent dentition is mature. If there is no complication, leaving the supernumerary premolars impacted is recommended. This case is about mental retardation patients with multiple supernumerary premolars.
