Lagomorph dental anatomy is characterized by which feature?

• A. Open roots
• B. Uneven enamel and molars and occlusal surfaces
• C. Comes into contact with opposite side
• D. Side to side mastication maintains wear

Answer: (A)

Lagomorphs have elodont dentition, meaning their teeth have open roots and continue to grow throughout life. This open-root setup allows ongoing eruption to counteract wear from gnawing fibrous vegetation, keeping the set of teeth functional as they’re worn down. If the teeth don’t stay properly aligned, they can overgrow and cause malocclusion, which is a common dental problem in rabbits and related species. The other aspects listed describe functional chewing patterns or surface wear but don’t define the distinctive anatomical feature of lagomorph teeth.
