theory II

Inflammatory response to dental biofilm

increased inflammatory response

progression from early lesion

extension of inflammation

which lesion occurs within 2-4 days of bacterial accumulation; white blood cells migrate to junctional epithelium; increase flow of gingival sulcus fluid; early breakdown of collagen of gingival fiber groups; and fliud fills spaces in connective tissue?

Which lesion has no clinical evidence of change in earliest phase; but later might show light marginal redness with enlargement?

Which lesion does; biofilm become older and thicker (7-14 days); fluid, lymphocytes, and neutrophils w/few plasma cells into connective tissue; breakdown of collagen fiber supporte; epithelial extensions and rete ridges form.

which lesion shows early signs of gingivitis becoming apparent with slt gingival enlargement; it is reversible if biofilm is controlled and inflammation reverese, helathy tissue may be restored; and susceptibility of individuals for this lesion varies

Which lesion has; fluid and leukocyte migration into tissues and sulcus increase; plasma cells related to area of chronic inflammation; pocket epithelium forms-proliferation of junctional and sulcular epithelium continues to try to wall out inflammation, pocket epithelium is more permeable, early pocket formation; connective tissue fibers lost.

which lesions clinical appearance is clear evidence of inflammation, present with marginal redness, bleeding on probing, and spongy marginal gingiva, later chronic fibrosis develops?

which lesion has subgingival biofilm which contain microorganisms containing irritants; alveolar bone destruction-inflammation spreads through the loose connective tissue beside the blood vessels to the alveolar bone, infection enters bone, inflammation spreads through the bone marrow and out into the periodontal ligament

What are the 5 steps in progression of connective tissue of the advanced lesion?

The following characteristics describe what lesion?
pocket formation; mobility; bone loss; periodontitis
persistence of chronic inflammatory process; plasma cells predominate
JE migrates more; lesion extends through CT
furcation

Inflammation of the gingiva characterized clinically by changes in color, gingival form, position, surface appearance, and presence of bleeding or exudate.

progression of the gingival inflammation into the deeper periodontal structure and alveolar bone crest, with slight bone loss. There is usually a slight loss of connective tissue at attachment and alveolar bone.

A more advanced stage of the preceding condition, with increased destruction of the periodontal structures and noticeable loss of bone support, possibley accompanied by an increase in tooth mobility. There may be furctaion involvement in multirooted teeth.

Further progression of periodontitis with major loss of alveolar bone support usually accompanied by increased tooth mobility. furcation involvement in multirooted teeth

a diseased sulcus

a pocket formed by gingival enlargement without apical migration of the junctional epithelium

the margin of the gingiva has moved toward the incisal or occlusal surface without the deeper periodontal structures involved; in what type of pocket?

the tooth wall is enamel in which type of pocket?

all gingival pockets are _________, that is the base of the pocket is coronal to the crest of the alveolar bone

a pocket formed as a result of disease or degeneration that caused the junctional epithelium to migrate apically along the cementum.

the tooth wall is cementum, or partly enamel and partly cementum in which type of pocket?

true or false. The periodontal pocket may be supra or intra-bony
True False

a pocket is narrow, and the pocket epithelium lining is adjacent to, and follows the _______ ___ ___ ________

When calculus deposits are present, the pocket wall follows the _____ ___ ____ __________

What are 5 things that may be inside a pocket in contact with the tooth surface on one side, and with the surface of the pocket epithelium on the other?

What happens as a result of continuing action of irritants and destructive agents from dental biofilm?

What are the first 3 pocket developement factors?

describe 4 surface changes that may occur in the event of pocket development

the clinical attachment level and bone loss have extended into the area between the roots of a multirooted tooth

early beginning involvement. A probe can enter the furca area, and the anatomy of the roots on either side can be felt by moving the probe from side to side

moderate involvement. bone has been destroyed to an extent that permits a probe to enter the furcation area but not to pass through between the roots

sever involvement. A probe can be passed between the roots through the entire furcation

Same as the previous class, with exposure from gingival recession, especially after periodontal therapy

What is the primary etiologic factor in the development of gingival and periondontal diseases?

true or false. dental biofilm cannot be removed completely by self-cleansing
True False

factors created by professionals during pt treatment or neglect of treatment. these are significant contributing factors in disease development

can factors such as mastication, saliva, the tongue, cheeks, lips, oral habits, and personal biofilm control procedures contribute to disease development?

a factor that is the actual cause of a disease or condition (like biofilm)

a factor that renders a person susceptible to a disease or condition (like smoking)

a factor that lends assistance to, supplements, or adds to a condition or disease (like meds, or diabetes)

an exposure that increases the probability that disease will occur (high BP, or family history of caries)

What are 4 dental factors that contribute to disease development?

What 3 gingiva factors contribute to disease deveolpment?

what are 2 'other' factors that contribute to disease development?

list 5 risk factors for periodontal disease

what factors for periodontal disease require a greater effort for the control of periodontal problems?

What are 3 drugs that lead to gingival enlargement?

true or false. an association with periodontal disease and all forms of tobacco has been shown, especially cigarette smokers.
True False

true or false. pts with diabetes are at increased susceptibility to periodontal infections. periodontal treatment improves the metabolic control of diabetes.

stress is considered a factor in the etiology of ________ ________ _________
