METHODS: Seventy-three patients with canine impaction and 73 control patients, without canine impaction, were evaluated. The mesiodistal distances of the maxillary lateral incisors adjacent to the impacted canines and the correspondent mandibular lateral incisors were measured. The adjacent lateral incisors were classified in: 1 - absent, 2 - small, 3 - peg-shaped, 4 - standard. RESULTS: The results showed that among the patients with impacted canines, there were 21 anomalous teeth (small and peg-shaped) and among the control patients there were only three small and peg-shaped teeth, with a statistically significant difference (p = 0.001). No patients were found with impacted canines and absent lateral incisors. CONCLUSION: It was concluded that in patients with anomalous lateral incisors (small and peg-shaped) there is a probability to present impacted canines and this must be considered. OBJETIVO: o objetivo foi obter informa o sobre a rela o existente entre a agenesia e/ou anomalia de forma de incisivos laterais superiores e impac o de caninos. M¨¦TODOS: foram avaliados 73 pacientes com impac o de caninos e 73 pacientes controle, sem impac o de caninos. Foram medidas as distancias mesiodistais dos incisivos laterais superiores adjacentes aos caninos impactados e os incisivos laterais correspondentes inferiores. Os incisivos laterais adjacentes foram classificados em: 1 - ausentes; 2 - pequenos; 3 - conoides; 4 - normais. RESULTADOS: os resultados mostraram que no grupo de pacientes com caninos impactados foram encontrados 22 dentes an malos (pequenos e conoides), e no grupo controle apenas tr¨ºs dentes pequenos e conoides, sendo uma diferen a estatisticamente significativa (p=0,001). N o foram encontrados pacientes com canino impactado e incisivo lateral ausente. CONCLUS O: concluiu-se que nos pacientes com incisivos laterais an malos (pequenos e conoides), a probabilidade de apresentarem caninos impactados existe e deve ser considerada. %K Incisivo %K Dente canino %K Anodontia %K Incisors %K Canine %K Agenesis %U http://www.scielo.br/scielo.php?script=sci_arttext&pid=S2176-94512012000600018
