ETIOLOGY Flashcards
(23 cards)
Conglomeration of microorganisms by indigenous microorganism
Periodontal disease
Merely inflammation of gingiva, stable and reversible
Gingivitis
Loss of attachment and reversible
Periodontitis
Tenacious mass consist of continually growing bacterial flora
Plaque
Rapidly liquified by bacterial enzymes and does not conatin any microorganisms
Food debris
Accumulation of tissue cells and bacteria without an organized structure
Materia alba
Serves as bacterial barrier but provide bacterial attachment
Pellicle
It can survive with or without oxygen
Facultative
It requires oxygen or not
Obligate
Why bacteria repel each other
The teeth as same ionic bond with the bacteria
It retain the stain and contains teichoic wall
Gram +
Bacteria that lose the color of the stain and absence of teichoic acid
Gram -
Who developed gram staining
Christian gram
Plaque doubling time is rapid in early and slower in more mature films
Plaque maturation
Ability of distinct bacteria to recognize and adhere to one another
Coaggregation
Look life fish scale
Pallisading
Side by side
Corn cob
What gram - bacteria can coaggregrate very well in other bacteria
Fusobacterium
Found above the gingival margin, it is whitish and greyish
Supragingival plaque
Plaque can be found below the gingival margin
Subgingival plaque
Implied that plaque caused diseased regardless of compostion, total plaque control is the treatment
Non specific plaque hypothesis
Single pathogenic species is the caused of inflammatory periodontal disease
Treatment: elimination of pathogen
Specifc plaque hypothesis
Mere presence of the pathogen is not enough to cause disease
Virulent clonal theory
