Computed tomography findings and severity grading of acquired dental disease in chinchillas (Chinchilla lanigera): 100 cases (2007-2023).

CT-based grading system standardizes acquired dental disease severity assessment in chinchillas.

This retrospective study analyzed CT findings in 100 chinchillas with acquired dental disease across 5 veterinary hospitals from 2007-2023. Both fan-beam (94 cases) and cone-beam (6 cases) CT protocols were evaluated. The most common findings included apical elongation of premolar or molar teeth (97 cases), with 58 cases extending into the orbit, tooth curvature in transverse (92) and sagittal (77) planes, and sharp dental points (91 cases). Additional pathology included dental resorptive lesions (64), fractures (38), alveolar expansile lesions (48), and infrequent abscesses (14). The authors developed a four-grade severity classification system (grade 1-4) for acquired dental disease, with cases distributed as: none (1), mild (38), moderate (28), and severe (33). This standardized grading scheme enables consistent assessment of dental pathology severity and progression monitoring. CT imaging proved effective for detailed evaluation of dental structures and associated complications in chinchillas, providing valuable guidance for treatment planning and prognostication.
