Oral Surgery · single question

A soft tissue laceration is identified on a patient's cheek. A separate wound shows superficial abrasion of the skin. How are these two injuries correctly distinguished?

  1. Laceration = deep cut/tear through tissue; abrasion = superficial scraping of the skin surface
  2. Laceration = superficial scratch; abrasion = deep cut
  3. Both are the same type of injury
  4. Abrasion = cut through mucosa; laceration = scraping of skin
Show answer and explanation

Correct answer: A. Laceration = deep cut/tear through tissue; abrasion = superficial scraping of the skin surface

  • A. Correct. A LACERATION is a tearing or cutting wound that penetrates through tissue layers — it may involve skin, mucosa, and deeper structures. An ABRASION is a superficial injury where the outer layer of skin or mucosa is scraped away — it does not penetrate deeply. These are distinct soft tissue trauma classifications used in dental emergency/trauma assessments.
  • B. The definitions are reversed in this option.
  • C. They are distinct injury types with different depth and management.
  • D. The definitions are reversed in this option.
