What is the abnormal alignment of teeth in rodents and rabbits called?

1. Misalignment

2. Malocclusion

3. Overbite

4. Underbite

The correct answer is: Malocclusion

The term that describes the abnormal alignment of teeth in rodents and rabbits is "malocclusion." In these animals, malocclusion occurs when the upper and lower jaws do not align properly, resulting in teeth that do not meet correctly. This misalignment can lead to continuous growth of the teeth, which can cause pain, inability to eat properly, and other health issues. In rodents and rabbits, both of which have continuously growing incisors, malocclusion can especially be problematic, leading to severe dental problems if not addressed. While misalignment could generically describe the issue, it lacks the specific dental implications associated with malocclusion. Overbites and underbites refer specifically to conditions regarding the bite relationship between upper and lower teeth but do not encompass the broader scope of improper alignment issues that can arise in the dental health of these animals. Understanding malocclusion is essential for maintaining the health and well-being of laboratory animals, as it directly impacts their feeding habits and overall quality of life.
