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 likely than controls to have external inflammatory root resorption (49 [49%] vs 25 [25%]) and retained roots (57 [56%] vs 28 [28%]). Fewer dental fractures occurred in cases (14 [14%]) than in controls (35 [35%]). There were no differences between cases and controls in breed, sex, or presence of feline resorptive lesions or buccal bone expansion. Conclusions and Clinical Relevance-Results suggested that FCGS was associated with more widely distributed and severe periodontitis, with a higher prevalence of external inflammatory root resorption and retained roots than other oral diseases. Full-mouth radiographic views are indicated for cats with FCGS to diagnose the extent of associated periodontitis, reveal external inflammatory root resorption, and identify retained roots.
