Q

Early Lesion

A

Biofilm olderand thicker
7-14 days
Clinical Appearance: Signs of gingivitis w/ slight gingival enlargement.
Gingivitis is reversible when biofilm is controlled
Depends on PT.

Q

Advanced Lesion

A

Biofilm microorganisms produce irritants
Alveolar bone destruction
Diseased cementum contains a thin superficial layer f endotoxins from bacterial breakdown.(what causes bone level stretch)
