Aim: Assess the labio-palatal position of maxillary impacted canines (MICs) on CBCT and their mesiodistal position on panoramic radiographs. Materials and Methods: This retrospective radiographic study reviewed 70 radiographs with MICs (40 bilaterally and 30 unilateral). Radiographs with, odontoma, mesiodenses, or cleft lip and palate were excluded. The mesiodistal position of the MICs was classified into four sectors on panoramic radiograph while their labiopalatal position were evaluated on CBCT. The correlation between panoramic sectors location and CBCT results was examined using the chi-square test. Results: Labial positioned MICs on CBCT were more frequent in panoramic sector 1, while palatally positioned MICs were more frequent in sectors 4. The association between sectors of the MICs on panoramic images and the labio-palatal position of the MICs on CBCT was statistically significant (P < 0.001). Conclusions: This study showed that, sector location on panoramic radiographs might be used for prediction of labiopalatal position of MICs.

“…No que respeita a metade dos médicos dentistas que não pedem CBCT, alguns estudos 6,7 demonstraram que este é mais preciso quando comparado com as técnicas paralaxe horizontais no diagnóstico de posição de caninos maxilares inclusos, sobretudo em casos complexos e não palpáveis. A ausência de CBCT pode acarretar consequências tais como planos de tratamento desadequados ou com mau prognóstico, surpresas indesejáveis, sobretudo no que respeita o grau de dificuldade do caso, dificuldade na exposição cirúrgica e/ou definição do vetor de tração ortodôntica, maior morbilidade do paciente por patologias císticas e reabsorções de dentes vizinhos que passam despercebidas, retalhos mal localizados e técnicas cirúrgicas mais invasivas.…”

r e s u m o informação sobre o artigo Historial do artigo: Recebido a 13 de dezembro de 2018 Aceite a 6 de dezembro de 2019 On-line a 3 de janeiro de 2020 Objetivos: Analisar a via de abordagem cirúrgica, no sentido vestíbulo-palatino, de caninos inclusos maxilares, comparando imagens bidimensionais com tridimensionais (gold standard). A taxa de abordagens corretas foi relacionada com a experiência e especialidade de médicos dentistas, tendo-se ainda avaliado a taxa de pedido de imagens tridimensionais para estudo destes casos. Métodos: A amostra foi constituída por 80 médicos dentistas inscritos na Ordem dos Médicos Dentistas, que voluntariamente aceitaram responder a um questionário constituído por radiografias panorâmicas e telerradiografias de trinta caninos maxilares inclusos. Todos os casos apresentavam tomografia computorizada de feixe cónico (CBCT) analisada por dois cirurgiões orais, que definiram a abordagem cirúrgica mais exata (gold standard) no sentido vestíbulo-palatino para cada canino. Tal serviu para confirmar ou refutar as escolhas das abordagens feitas nos questionários. Resultados: Não parece existir relação entre a taxa de abordagens corretas e a experiência, porém foi encontrada quanto à especialidade, com os cirurgiões orais a escolheram mais vezes a via de abordagem correta do que generalistas (p=0,034). Não foram encontradas diferenças entre as restantes especialidades (p>0,05). Existe associação entre a especialidade e o pedido de CBCT (p=0,008), sendo mais provável que cirurgiões peçam sempre. Conclusão: Com base nos dados obtidos neste estudo verificou-se a existência de uma relação entre a especialidade do Medico Dentista (Cirurgia Oral), o número de abordagens cirúrgicas corretas de caninos maxilares inclusos e o pedido de exames complementares de

“…With CBCT, it is possible to more accurately locate the exact position of the teeth involved in 3 dimensions, aiding predictions of difficulty and the mechanics required. 15 The introduction and growth of use of CBCT has moved faster than the availability of definitive or evidence-based clinical guidelines for many areas of dentistry, including diagnosis of ectopic canines. 16 CBCT scanning was unavailable at the time of treatment.…”

Transposition of the maxillary canine and the lateral incisor is a complex dental anomaly to treat. The difficulty increases if the treatment aims to correct the transposition. These case reports describe 2 patients with transposition of the maxillary lateral incisor and canine. The first case involves bilateral incomplete transpositions, and the second is a complete transposition. The radiographic appearance of the canine was similar in the 2 patients. However, the treatments were distinct because of the 3-dimensional positions of the teeth. The first case involved palatally placed lateral incisor roots. To prevent resorption of the lateral incisors, the canines were moved into position buccally. In the second case, the lateral incisor root had a buccal position, and the canine crown was tractioned palatally. The position of the lateral incisor root was critical when electing the correct treatment and mechanics for each patient.
