“…The development of dentigerous cysts is commonly associated with unerupted teeth in humans and animals (68, 69). Several veterinary case reports (21, 25, 28–30, 32–34, 37, 42, 50, 52–54, 57, 60, 70) and a few retrospective studies (13, 14, 20) describe dentigerous cysts associated with unerupted teeth in dogs. Cysts may develop by accumulation of fluid between the REE and enamel, or between the layers of enamel epithelium itself, but the exact pathogenetic mechanism remains unclear (71).…”

Lack of dental eruption may be accompanied by development of dentigerous cysts and has also been rarely associated with neoplasia. However, little information is available on prevalence of unerupted teeth and associated lesions in dogs and cats. The main objective of this study was to describe the epidemiologic data of canine and feline dental patients with unerupted teeth, and assess the prevalence of associated dentigerous cysts and tumors. Secondary aims included the evaluation of possible factors implicated in cystic development, and description of the histological features of dentigerous cysts. Medical and dental records, intraoral photographs, intraoral radiographs of client-owned dogs and cats with clinically missing teeth examined between 2001 and March 2018 were reviewed. Collected data included signalment, reason for presentation, number, type, depth of inclusion and angulation of unerupted teeth, presence of cystic lesions or tumors, abnormalities affecting involved teeth, histopathological findings, performed treatment and outcome. Seventy-three animals (69 dogs and 4 cats) with 113 unerupted teeth were included. The most frequent unerupted tooth in dogs was the first premolar teeth (78%), followed by the canine and third molar teeth. Dentigerous cysts were diagnosed associated with 48 (44.4%) teeth in dogs and one out of five unerupted teeth in cats. The affected teeth in dogs were predominantly in horizontal inclination (40%) and in soft tissue inclusion (77%). Brachycephalic canine breeds were overrepresented. The only unerupted tooth in boxer dogs was the first premolar tooth (32 teeth). Ninety percentage of boxers with unerupted teeth developed associated lesions (25 dentigerous cysts and one tumor). Two ameloblastomas (one in a dog and one in a cat) and one osteosarcoma (in a dog) were diagnosed in association with three unerupted teeth. Histology was essential in diagnosing two odontogenic cysts not evident on radiographs. In all cases that were followed-up, treatment (i.e., extraction, extraction and surgical curettage, or operculectomy) appeared successful. Untreated dentigerous cysts showed progression at re-examination. None of the unerupted teeth without evidence of cyst at the time of diagnosis showed incipient cystic development. None of the evaluated factors were associated with lack of eruption and/or development of associated lesions.

“…O cisto dentígero é o cisto odontogênico benigno mais comum em cães. Todavia, sua incidência é baixa, e está associado a dentes inclusos, ocorrendo principalmente no primeiro pré-molar mandibular de cães braquicefálicos e de pequeno porte (BELLEZZA et al, 2008;KUYAMA et al, 2009;D`ASTOUS, 2011;MACGEE et al, 2012;HONZELKA et al, 2014;MACGEE, 2014;VOELTER-RATSON et al, 2015;REQUICHA et al, 2015;BABBITT et al, 2016;HOLLY et al, 2018;HOYER et al, 2016;PERRY, 2017).…”

“…Os cistos dentígeros podem alcançar tamanhos significativos durante sua lenta expansão, levando a fraturas patológicas decorrentes de destruição óssea, invasão da cavidade nasal, reabsorção ou problemas endodônticos em dentes vizinhos, e podem em alguns casos se tornar malignos (D`ASTOUS, 2011;MACGEE et al, 2012;MACGEE, 2014;MOORE;NIEMIEC, 2014;VOELTER-RATSON et al, 2015;NIEMIEC, 2015;BABBITT et al, 2016;PERRY, 2017;THEYSE, 2017).…”

“…Os animais acometidos geralmente não apresentam sinais clínicos além da hipodontia. No entanto, em lesões mais avançadas, pode ocorrer assimetria facial e presença de uma massa flutuante ou firme (D`ASTOUS, 2011;MACGEE et al, 2012).…”

“…Para o diagnóstico dos cistos dentígeros é essencial a realização de radiografias intra-orais, que permitem observar uma lesão circular radioluscente com um córtex bem definido. Além disso, recomenda-se realizar exame histolopatológico do material extraído (KUYAMA et al, 2009;D`ASTOUS, 2011;MACGEE et al, 2012;HONZELKA et al, 2014;MACGEE, 2014). Por outro lado, grandes cistos dentígeros podem ser confundidos com granulomas, abscessos, lesões fibro-ósseas, tumores e outros tipos de cistos (KUYAMA et al, 2009;D`ASTOUS, 2011;HONZELKA et al, 2014).…”

RESUMO A persistência de dentes decíduos é uma condição comum e acomete principalmente cães de raças pequenas e miniaturas. Pode levar a diversas alterações orais, sendo indicada a extração desses dentes decíduos persistentes. Dentes inclusos são aqueles cuja erupção não ocorreu, e devem ser extraídos para evitar complicações como a formação de cistos odontogênicos. Os cães braquicéfalos são os mais suscetíveis, e o cisto dentígero é o cisto odontogênico mais comum em cães. Mesmo sendo benigno, pode alcançar tamanhos significativos, levando a diversas alterações locais. Este artigo relata um de caso sobre persistência de três dentes decíduos e presença de dois dentes inclusos, sendo um deles associado a um cisto dentígero, em um cão Shuh-Tzu adulto. Discute-se diagnóstico, tratamento cirúrgico e evolução do caso. PALAVRAS-CHAVE: exodontia, extração dental, odontologia, odontologia veterinária.
