Summary
# Editorial Summary: Diagnostic Imaging of Equine Cheek Teeth Pathology Pulpar and apical infections in equine cheek teeth frequently progress to involve alveolar bone and paranasal sinuses, yet the diagnostic reliability of imaging modalities remains poorly characterised. Researchers examined 30 pathological cheek teeth from equine cadavers using computed tomography (CT), radiography, gross dissection, histology, and detailed dental/alveolar analysis to directly correlate imaging findings with actual tissue damage. CT imaging proved substantially more sensitive than radiography for detecting lesions of the dental and alveolar structures, particularly in early-stage infections and those affecting bone density rather than producing obvious lytic changes. Findings revealed significant discrepancies between what standard radiographs demonstrated and the actual extent of alveolar and pulpal pathology present, highlighting CT's superior diagnostic capability for treatment planning and prognostication in cases of suspected cheek tooth disease. For clinical practitioners managing equine dental disorders, these results support the judicious use of CT imaging—particularly when radiographic findings appear inconclusive or when precise definition of alveolar involvement is essential for determining whether extraction, endodontic treatment, or conservative management is most appropriate.

Practical Takeaways
- •CT imaging is a valuable diagnostic tool for assessing the extent of cheek tooth disease beyond what radiographs can show, particularly for detecting alveolar and sinus involvement
- •Pulpar and apical infections should be treated aggressively as they commonly spread to bone and sinuses, potentially explaining why some teeth do not respond to conservative management
- •When faced with clinical signs of cheek tooth disease, advanced imaging (CT) may be warranted to fully characterize lesion extent before pursuing treatment or extraction
Key Findings
- •CT imaging was compared directly against gross pathology and histology in 30 abnormal equine cheek teeth, establishing baseline diagnostic accuracy
- •Pulpar and apical infections frequently extended to supporting alveolar bone and paranasal sinuses, confirming the serious consequences of these disorders
- •This was the first study to directly correlate CT imaging findings with pathological examination of diseased tooth alveoli in horses
