摘要:
AbstractHypodontia has been observed as one of the most common human dental developmental anomalies. It may be defined as agenesis of one or more teeth. The prevalence in the permanent lower central and lateral incisor region is low, ranging from 0.23 per cent to 0.08 per cent, respectively. This is compared with an overall incidence of hypodontia of 3.49 per cent. However, significant racial variation occurs. Treatment options generally available are: no treatment, closure of spaces orthodontically, or prosthetic replacement. Aetiology, associated anomalies, and factors involved in treatment choice are discussed. A report of four cases of hypodontia of the permanent lower anterior teeth and their orthodontic management is presented.
