Dens evaginatus in the Vietnamese.

Dens evaginatus (supernumerary cusps in premolars) were detected in 50 of 4677 Vietnamese patients examined. A systematic study including morphologic, histologic, pathologic aspects of dens evaginatus was carried out and data were compared with those given in previous reports pertaining to dens evaginatus in other Asian countries. It is expected that a better knowledge concerning this anomaly will lead to appropriate measures for prophylactic treatment of dens evaginatus.
