Radicular Cyst of the Premaxilla in a Dog

Abstract

A 13-year-old, male/neutered Border Collie dog was diagnosed with a radicular cyst of the left premaxilla. Tooth extraction and curettage of the lesion resulted in a positive clinical outcome 6-months following treatment.

Clinical behavior and management of odontogenic cysts

“…[4][5][6][7]21 PC are strictly inflammatory cysts associated with a preexisting periapical granuloma of a nonvital tooth. [4][5][6][7]21 PC are strictly inflammatory cysts associated with a preexisting periapical granuloma of a nonvital tooth.…”

“…1,[3][4][5][6][7][8][9][10][11][12][13] In humans, the majority of cystic jaw lesions are discovered incidentally on screen ing studies. 1,2 OC reported in dogs and cats include dentiger ous cysts, periapical cysts and odontogenic keratocysts.…”

Extensive Bilateral Odontogenic Cysts in the Mandible of a Dog

“…1 Types of odontogenic cysts reported in dogs include radicular cysts, dentigerous cysts, and keratocysts. 2,4,8,10,12 In contrast to other odontogenic cysts, radicular cysts are associated with an inflammatory infiltrate. 6 They are also very often found in association with a devitalized tooth.…”

“…8 Treatment via curettage was reported in 2 previous cases of radicular cysts in dogs. 2,4 This treatment was judged to be effective, with no disease recurrence found at 6 2 and 14 4 months after surgery. The cysts of the dog in this case report were extensive and bilateral.…”

“…4 Radicular cysts are the most common type of oral cyst in humans 7 but have only been reported 3 times in the dog. 2,4,10 The purpose of this paper is to report bilateral odontogenic cysts, in the mandible of a dog, that are difficult to fully characterize within current classification schemes.…”
