Week 2 Chapter 3-5 Flashcards
Disease progression
the sequence of events that occur during the development of a
disease or abnormal condition
- disease progression may vary from:*
- (1) one individual to another*
- (2) one site to another in a person’s mouth,*
- (3) one type of periodontal disease to another.*
Gingivitis
a type of periodontal disease characterized by changes in the color, contour, and consistency of the gingival tissues
Reversible (tissue damage)
when the body can repair the damage
Periodontitis
a type of periodontal disease that is characterized by the
apical migration of the JE,
loss of connective tissue attachment,
and
loss of alveolar bone
Irreversible tissue damage
permanent tissue damage
apical migration of the junctional epithelium (JE)
the movement of the junctional epithelium apical to its normal location
Inflammation
the body’s response to injury or invasion by
disease-producing organisms
Alveolar bone loss
the resorption of alveolar bone as a result of periodontitis
Horizontal bone loss
results in a fairly even, overall reduction in the height of the alveolar bone
Vertical bone loss
results in an uneven reduction in the height of the alveolar bone
Osseous defect
bony defects
Infrabony defect
results when bone resorption occurs in an uneven,
oblique direction
(primarily affects one tooth)
Osseous crater
a bowl-shaped defect in the interdental alveolar bone with bone loss
nearly equal on the roots of two adjacent teeth
the presance of a crater causes dental plaque biofilm to accumulate in the interdental area.
Furcation involvement
occurs on a multirooted tooth when periodontal infection
invades the area between and around the roots, resulting in a loss of
alveolar bone between the roots of the teeth
Bone loss in the furcation area may be hidden by the gingival tissue
or may be clinically visible in the mouth
Attachment loss
the destruction of the fibers and bone that support the teeth
Tissue destruction does not spread only in an apical (vertical) direction
but also in a lateral (side-to-side) direction.
