What dental term describes an injury from misalignment of teeth during closure?

  1. Dental caries

  2. Occlusal trauma

  3. Periapical abscess

  4. Buccal vestibule irritation

The correct answer is: Occlusal trauma

The correct term to describe an injury resulting from the misalignment of teeth during closure is occlusal trauma. This condition occurs when there is an improper bite relationship, which can lead to excessive force being applied to certain teeth. Over time, this can cause various dental issues, including tooth wear, discomfort, and even structural changes in the bone surrounding the teeth. Understanding occlusal trauma is essential in dentistry, as it helps in diagnosing problems related to bite misalignment and designing appropriate treatment plans, such as orthodontics or occlusal adjustments. The other terms do not correctly describe this condition. Dental caries refers to tooth decay caused by bacteria and does not pertain to misalignment issues. A periapical abscess is an infection at the tip of the tooth's root, often resulting from untreated dental caries or trauma, rather than misalignment. Buccal vestibule irritation pertains to inflammation or soreness in the vestibule area of the mouth, which is unrelated to the alignment of teeth during biting.
