Retained Deciduous Tooth Root Remnants in Dogs: A Ten-Year Retrospective Study

Area of Science:

• Veterinary Dentistry
• Canine Oral Health
• Radiology

Background:

• Retained deciduous tooth root remnants are a recognized issue in veterinary dentistry.
• These remnants can lead to various oral pathologies if left untreated.

Purpose of the Study:

• To determine the incidence of retained deciduous tooth root remnants in dogs.
• To identify the clinical consequences and radiographic changes associated with these remnants.
• To highlight the importance of early radiographic detection.

Main Methods:

• Retrospective review of 5432 canine medical records from a referral clinic (2013-2023).
• Radiographic identification and analysis of retained deciduous tooth root remnants.
• Evaluation of associated radiographic changes and clinical complications.

Main Results:

• 237 retained root remnants were identified in 143 dogs.
• Most common sites were maxillary canine teeth (left 39.2%, right 33.7%).
• 81.8% of affected dogs showed complications, including periapical radiolucency (44.1%) and root resorption/ankylosis (37.8%).
• Dental malocclusion was also noted.
• Yorkshire Terriers were disproportionately represented (41.2%).

Conclusions:

• Retained deciduous tooth root remnants do not resorb naturally and frequently lead to clinical complications.
• Routine full-mouth radiography is essential for identifying these abnormalities and preventing secondary issues.
• Prompt diagnosis and management are vital for canine dental health.
