Summary
# Editorial Summary: Oral Endoscopy in Equine Cheek Tooth Diagnosis When a horse presents with clinical signs of dental disease but radiographs and external examination fail to reveal obvious pathology, identifying the culprit tooth becomes considerably challenging—particularly when considering that extraction carries significant morbidity risk. Ramzan's 2009 analysis examined 17 cases of apical cheek tooth infection that had resisted antibiotic therapy despite the absence of gross oral abnormalities, utilising rigid oral endoscopy alongside conventional radiography to localise disease. Endoscopic examination successfully identified tooth-specific abnormalities in 15 of the 17 cases (88%), with focal gingival recession being the most frequently observed sign (10 cases), followed by other intraoral changes localised to the infected tooth. The practical significance lies in rigid oral endoscopy's capacity to provide definitive diagnostic confirmation before committing to extraction, potentially preventing unnecessary removal of contralateral or non-diseased teeth and reducing post-operative complications. For practitioners managing antibiotic-refractory dental cases with equivocal radiographic findings, incorporating oral endoscopy into the diagnostic protocol offers a valuable tool to guide treatment decisions and improve clinical outcomes.

Practical Takeaways
- •Use oral endoscopy alongside radiography when evaluating suspected cheek tooth infections, especially when clinical signs are subtle or absent
- •Look for focal gingival recession as a key diagnostic indicator of apical infection—this finding alone should prompt further investigation before proceeding to extraction
- •Rigid oral endoscopy under standing sedation provides a non-invasive diagnostic option that can reduce unnecessary tooth extractions in ambiguous cases
Key Findings
- •Oral endoscopy revealed abnormalities specific to infected teeth in 88% (15/17) of cases with apical infection but no gross oral pathology
- •Focal gingival recession was the most common visible abnormality, identified in 10 of 17 infected cases
- •Oral endoscopy can facilitate diagnosis of cheek tooth infections when radiography and clinical examination are inconclusive
- •Standing sedation with rigid oral endoscopy permits detailed examination of oral cavity and erupted dental tissues
