Agenesis of permanent mandibular anterior teeth: a case report.

Tooth agenesis is one of the common congenital anomalies seen in humans. Hypodontia is the congenital absence of 1 or a few teeth only, with a prevalence of approximately 2% to 10% in the permanent dentition. The number of patients exhibiting congenitally missing mandibular incisors is low, with a prevalence rate of less than 1% observed. The purpose of this paper was to report a case of congenitally missing permanent mandibular incisors and canines in a 10-year-old girl.
