Read the first 7 Periodontal Concepts flashcards as text

  1. Which of the following best describes the biologic width?

    Answer: Combined length of junctional epithelium and supracrestal connective tissue attachment

    Biologic width refers to the combined dimension of junctional epithelium (~1 mm) and supracrestal connective tissue attachment (~1 mm), totaling approximately 2 mm.

  2. A patient taking phenytoin (Dilantin) is most likely to exhibit which periodontal condition?

    Answer: Gingival enlargement (overgrowth)

    Phenytoin causes drug-induced gingival enlargement due to increased fibroblast proliferation and altered collagen metabolism.

  3. What is the role of matrix metalloproteinases (MMPs) in periodontal destruction?

    Answer: They degrade collagen and extracellular matrix proteins in periodontal tissues

    MMPs, particularly MMP-8 and MMP-13, degrade collagen and extracellular matrix components, contributing to connective tissue destruction in periodontitis.

  4. Necrotizing periodontal disease is characterized by all of the following EXCEPT:

    Answer: Painless presentation

    Necrotizing periodontal diseases (NUG/NUP) are characteristically painful; pain differentiates them from other forms of periodontal disease.

  5. Which radiographic bone pattern is characterized by bone loss that is NOT parallel to an imaginary line drawn between the CEJ of adjacent teeth?

    Answer: Vertical (angular) bone loss

    Vertical or angular bone loss occurs at an angle to the long axis of the tooth and is typically associated with intrabony defects.

  6. The 'red complex' pathogens in periodontal microbiology include which combination?

    Answer: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola

    The red complex, identified by Socransky et al., consists of Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola and is most strongly associated with severe periodontitis.

  7. Which of the following best describes a pseudo-pocket (false pocket)?

    Answer: Increased probing depth due to coronal enlargement of the gingival margin without loss of attachment

    A pseudo-pocket forms when gingival enlargement increases the probing depth without actual apical migration of the junctional epithelium or loss of attachment.
