Radiographic Prevalence of Nonvital Incisor Teeth in Small Breed Dogs: A Retrospective Study (2017-2021).
Clinical evidence update from Journal of veterinary dentistry
Clinical Context
Peer-reviewed veterinary literature continues to shape everyday decision-making for canine patients, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.
What the Study Evaluated
A study published in Journal of veterinary dentistry in 2026 evaluated radiographic Prevalence of Nonvital Incisor Teeth in Small Breed Dogs: A Retrospective Study (2017-2021)..
Key Findings
The purpose of this retrospective study was to determine the prevalence of nonvital incisor teeth in small breed dogs. Intraoral maxillary and mandibular radiographs of the incisor teeth obtained between January 1, 2017 and December 31, 2021 in 287 dogs previously diagnosed as having nonvital teeth and weighing <10 kg were reviewed. A total of 2682 incisor teeth were assessed and were diagnosed as nonvital if one of the following radiographic criteria was met: widened pulp canal; widened apical periodontal ligament space; periapical radiolucency; internal root resorption; external root resorption; and changes in the trabecular bone pattern...
Why It Matters for Veterinary Professionals
For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for canine patients.
Practical Interpretation
The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.
Clinical Takeaway
Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
