Oral Fractures in Dogs of Brazil — A Retrospective Study

Abstract

A retrospective study was performed in 100 dogs with 121 mandibular and 21 maxillary fractures. Dog fight (43.0%) and automobile (12.0%) trauma were the most common etiologies for fracture. The cause of fracture was unknown in 23.0% of the cases, while pathologic fractures occurred in 13.0% of cases. Young dogs (< 1-year-old) and dogs > 8-years of age were most affected. Mandibular fractures occurred in 90 dogs (90.0%), with two dogs (2.2%) having concurrent maxillary fractures. Maxillary fractures only were diagnosed in 10 dogs (10.0%). The molar region (47.1%) was the most commonly affected location for mandibular fracture, followed by fractures of the symphysis and parasymphysis (30.6%), premolar region (17.4%), angular process (4.1%) and vertical ramus (0.8%). In fractures of the mandibular region, the mandibular first molar tooth was often (85.9%) involved while the canine teeth were involved in 67.5% of symphyseal and parasymphyseal fractures. The most common fracture of the maxilla was the maxillary bone (52.4%), followed by the incisive (33.3%), palatine (9.5%), and nasal (4.8%) bones.

Diagnóstico de alterações neurológicas compressivas da medula espinal de cães com o uso da Tomografia Computadorizada (TC) Helicoidal

“…Em alguns casos, as projeções ósseas podem ser lancetantes e gerar hemorragia como meio compressivo secundário a este processo (Sande & West 2010). Os acidentes automobilísticos estão entre as causas mais comuns de fraturas (Lopes et al 1990;Umphlet e Johnson 1990). Como a natureza é incidental, não há fatores predisponentes.…”

Regeneração periodontal em cães

“…Nos casos mais avançados da doença, nos quais existe grande reabsorção óssea, são comuns a formação de comunicações oronasais e a ocorrência de fraturas patológicas de mandíbula, principalmente, nos animais de raças pequenas (HARVEY, 1998;WIGGS et al, 1998). As fraturas patológicas de mandíbula são de especial importância por serem de difícil manejo clínico-cirúrgico (LEGENDRE, 2003) e apresentarem prevalência considerável, correspondendo a 13% das etiologias de fraturas de mandíbula em estudo realizado no Brasil (LOPES et al, 2005).…”

Kedilerde Symphisis Mandibula Ayrilmalarinin ve Parasymphiseal Kiriklarin Sağaltiminda İnterdental ve İnterfragmenter Stabilizasyon (İVİS): Yeni Bir Teknik

“…In dogs, the area between two mandibular canine teeth is described as the parasymphyseal region. Mandibular symphysis separations and fractures including the canine tooth are regarded as parasymphyseal fractures and the incidence has been calculated [13] . In this study, the authors considered cases in which the mandibular symphysis separation started rostrally and continued ventrally incorporating a fragment of one hemimandibula, to be cases with a parasymphyseal fracture.…”
