Delli K Livas C Bornstein MM 2013 OBJECTIVE To assess the prevalence of lateral incisor agenesis impacted canines and supernumerary teeth in a young adult male population. MATERIALS AND METHODS The panoramic radiographs of 1745 military students (mean age: 18.6 ± 0.52 years) who attended the Center of Aviation Medicine of the Armed Forces of Greece during the period 1997-2011 were initially analyzed for lateral incisor agenesis by two observers. After exclusion of the known orthodontic cases, a subgroup of 1636 examinees (mean age: 18.6 ± 0.44 years) was evaluated for canine impaction and supernumerary teeth. RESULTS Twenty-eight missing lateral incisors were observed in 22 military students, indicating an incidence of 1.3% in the investigated population. No lateral incisor agenesis was detected in the mandibular arch. A prevalence rate of 0.8% was determined for canine impaction in the sample of young adults. The majority of impacted teeth (86.7%) were diagnosed in the maxillary arch. Thirty-five supernumerary teeth were observed in 24 examinees (prevalence rate: 1.5%). The ratio of supernumerary teeth located in the maxilla versus the mandible was 2.2:1. The most common type of supernumerary tooth was the upper distomolar. CONCLUSION The prevalence of lateral incisor agenesis, canine impaction, and supernumerary teeth ranged from 0.8 to 1.5% in the sample of male Greek military students. https://sonar.ch/global/documents/362 eng info:eu-repo/semantics/altIdentifier/doi/10.4103/1305-7456.115410 info:eu-repo/semantics/altIdentifier/pmid/24926206 European journal of dentistry. - 2013 Canine impaction lateral incisor agenesis prevalence supernumerary teeth young male adults Lateral incisor agenesis, canine impaction and characteristics of supernumerary teeth in a South European male population. http://purl.org/coar/resource_type/c_6501
