The prevalence of peg-shaped lateral incisors is higher among Mongoloid people. The peg-shaped lateral incisor is one that has an incisal mesiodistal width of the tooth crown shorter than the cervical width. This can lead to aesthetic, orthodontic and periodontal problems for the patient. The aim of this review was to assess the prevalence in relation to race, sex, population type and continent of origin.
