Dental radiographic findings in cats with chronic gingivostomatitis (2002–2012)

Objective—To compare dental radiographic findings in cats with and without feline chronic gingivostomatitis (FCGS). Design—Retrospective case-control study. Animals—101 cats with FCGS (cases) and 101 cats with other oral diseases (controls). Procedures—Controls were age- and treatment date–matched with cases. Conventional full-mouth dental radiographic views were evaluated for distribution, pattern, and severity of alveolar bone loss (periodontitis), tooth resorption, buccal bone expansion, tooth fractures, and retained roots. Results—All cases and 77 (76%) controls had periodontitis; differences in extent and severity of periodontitis were significant, with semigeneralized or generalized and moderate or severe periodontitis in 78 (77%) and 93 (92%) cases, respectively, and 28 (28%) and 38 (38%) controls, respectively. The pattern of alveolar bone loss in cases was dominated by horizontal bone loss, with a nonsignificant increase in vertical bone loss, compared with that of controls. Cases were more likel...
