Oligodontia, a form of hypodontia commonly seen in permanent than in deciduous dentition. It is defined as the congenital absence of six or more teeth, excluding third molars. It is relatively a rare condition that can occur either as an isolated finding or as part of a syndrome. A case of nonsyndromic oligodontia in a 12-year-old boy with congenital absence of all permanent teeth except the premolars (excluding third molars) and over-retained deciduous dentition with conical shaped anteriors is reported. The prevalence, possible etiological factors and treatment options of the condition is reviewed.
