Summary

# Editorial Summary Understanding the progressive changes in equine cheek tooth pulp morphology across different ages is essential for diagnosing and treating endodontic disease, yet detailed anatomical data have been limited to sectional studies or clinical-resolution imaging. Kopke and colleagues employed micro-computed tomography (µCT) at approximately 0.1 mm resolution, combined with three-dimensional reconstructions and histological verification, to map physiological pulp cavity configurations across a comprehensive age spectrum of both mandibular and maxillary teeth. The high-resolution technique revealed the complex, age-dependent changes in pulp morphology driven by continuous secondary dentine deposition—information substantially more detailed than previously available from either sectioned teeth or standard CT imaging. These precise anatomical datasets provide the foundation necessary for farriers and veterinarians to better interpret clinical presentations of endodontic pathology and establish evidence-based protocols for therapeutic interventions. For practitioners, the work underscores why pulp anatomy changes predictably with age and offers a reference framework for recognising when pathological changes have deviated from normal physiology.

Practical Takeaways

•Understanding how pulp cavities change with age helps explain why older horses develop specific endodontic problems and informs treatment planning
•High-resolution imaging of pulp anatomy provides a foundation for developing better endodontic therapies in equine dentistry
•This anatomical baseline is critical for diagnosing pulp involvement in cheek tooth disease and predicting treatment outcomes

Key Findings

•Micro-computed tomography at 0.1 mm resolution can precisely visualize three-dimensional pulp cavity morphology in equine cheek teeth across all age groups
•Secondary dentine production causes progressive, age-related changes to the endodontic cavity that are distinct and measurable
•Detailed anatomical knowledge of pulp system configuration is essential for understanding the aetiopathology of equine endodontic diseases
