Exam 2 Flashcards
Definition: thin acellular film derived mainly from salivary glycoproteins that forms within minutes of a cleansed tooth crown when exposed to saliva.
Acquired pellicle
Why is it more difficult to control intraoral biofilms?
Several hundred different types instead of just one
Slime layer developed during ___ colonization.
Secondary
Subgingival calculus found mainly on:
Fluting
Furcations
Overhangs
Interproximal
Primary cause of perio disease
Subgingival bacteria
Substrate must be present prior to calculus formation
Biofilm
Minerals usually found in calculus
Calcium and Phosphate salts
Minerals most likely to be found Subgingivally
?
Time involved for calculus formation __-__ then will continue to mineralized to calculus in __-__
24-48 hours
10-20 days
Why biofilm disruption and removal are important in disease prevention, healing, and management
No biofilm=no calculus
Decreased biofilm aids in reducing infection
Prevent pathogenic subgingival biofilm to maintain any earlier healings
Importance of frequency in biofilm removal
So that pathogenic biofilm does not develop. Disease prevention!
Criteria for replacing a toothbrush
As soon as the bristles start to flare or get worn
