Ch. 7-Mucogingival Deformities and Conditions around teeth

Normal Mucogingival condition

Conditions that are commonly observed in the absence of any underlying disease state—occur because of congenital reasons or developmental reasons

CAN

In normal mucogingival conditions, health ______ still be maintained

Mucogingival deformity and condition

Any defect associated with deviation from normal anatomic/ morphologic relationship between gingiva and alveolar mucosa.

ALL AGE GROUPS SUSCEPTIBLE

Gingival recession

Movement of gingival margin to point apical to CEJ.

MOST COMMON mucogingival deformity, affects anyone, but prevalence increases with age.

Attachment loss

Recession corresponds to ______ _______ that exposes root surfaces to oral environment

thin-scalloped, thick-scalloped, thick-flat

3 biotypes

Thick-scalloped biotype

Slender, triangular shaped crown; THICK, fibrotic gingiva.

Thick

Thin/thick:

Accentuated scalloped gingival margin contour; despite having thick, fibrotic gingiva, prone to development of mucogingival deformity

Narrow to moderate

Thick scalloped biotype have a ___________ to __________ zone of keratinized tissue

Thin-scalloped biotype

slender, triangular-shaped crown; it’s thin, delicate, friable soft tissue with thin alveolar bone

Narrow

Thin scalloped biotype has a ________ zone of keratinized tissue

Thin

Thin/thick:

Accentuated scalloped gingival margin contour; greater tendency for onset, progression of mucogingival deformity

Thick-flat biotype

Wide, square-shaped crown; thick, dense, and fibrotic tissue

wide

Thick flat biotype has a __________ band of keratinized tissue

Thick-flat

Thick-flat/thin-flat:

Flat gingival margin contour; more resilient and less susceptible to inflammation and trauma than thin- and thick- scalloped biotypes

Periodontal biotype

Describes features of the periodontium, such as gingival thickness, gingival width and the shapes of hte dental crown that are influenced by both genetics and environmental factos

False- it can vary among different teeth (within the same individual)

True/False- Periodontal biotype is always the same among different teeth within the same individual

Miller classification system

Which classification system is most widely used for nearly 4 decades, is based on level of gingival margin with respect to mucogingival junction and underlying alveolar bone, and it consists of four recession categories
