Summary
# Editorial Summary: The Equine Gingiva: A Gross Anatomical Evaluation Periodontal disease in horses typically progresses insidiously from food impaction and diastemata formation through to gingival inflammation and eventually tooth loss, yet early detection remains challenging because examination protocols have been largely borrowed from small animal dentistry without accounting for anatomical differences between species. Researchers conducted macroscopic examination of 20 equine heads, systematically documenting gingival morphology across the upper and lower cheek teeth, incisor regions, and both vestibular and lingual/palatal aspects, with particular focus on the gingival sulcus depth, gingival margin contours, and interdental papillae architecture. The study identified consistent morphological patterns in healthy equine gingiva that are distinct from canine anatomy, and crucially found that gingival sulci exceeding 1 mm were present in only 6% of specimens—suggesting that deeper sulci may represent a more reliable early pathological indicator in horses than the diagnostic thresholds adapted from small animal protocols. These anatomical parameters provide equine professionals with species-specific reference standards for recognising early periodontal disease, enabling development of targeted examination and grading systems that could facilitate intervention before advanced destruction of periodontal support structures necessitates extraction. Practitioners should be aware that canine-derived examination criteria may not accurately detect early equine periodontal disease, and that familiarity with normal equine gingival anatomy—particularly the typical shallow sulcus depth—is essential for identifying pathological change.

Practical Takeaways
- •Familiarize yourself with normal equine gingival anatomy — the gingival margin, interdental papillae, and shallow gingival sulcus — to recognize early signs of periodontal disease before advanced stages requiring extraction
- •Existing equine periodontal examination protocols adapted from small animal medicine may be unreliable; look for protocols based on equine-specific anatomical features
- •Early detection of periodontal disease is possible with proper anatomical knowledge, potentially preventing progression to tooth loss and the need for extraction
Key Findings
- •Constant morphological patterns of gingival margin and interdental papillae were identified across vestibular and lingual/palatal aspects of cheek teeth and incisor arcades
- •Gingival sulcus measuring greater than 1 mm was present in only 6% of specimens examined
- •Equine gingival anatomy differs substantially from canine anatomy, requiring species-specific examination protocols rather than adaptation of small animal protocols
