Biologic width is composed of which tissue components?
Show answer and explanation
Correct answer: A. Junctional epithelium plus the supracrestal connective tissue attachment
The biologic width (supracrestal tissue attachment) consists of the junctional epithelial attachment plus the connective tissue attachment above the alveolar crest (about 2 mm total); violating it causes inflammation and bone loss.Other options: The other combinations do not define the supracrestal attachment apparatus.Key exam takeaway: Biologic width = junctional epithelium + connective tissue attachment (~2 mm); do not violate with restorative margins.
