WILL be on the final (in my opinion) Flashcards
1
Q
BIOFILM FORMATION TIMELINE
A
2
Q
What is step 1 of biofilm formation?
A
Pellicle forms first on the tooth, providing bacteria a surface to attach to
3
Q
What is step 2 of biofilm formation?
A
Within 2 hours, bacteria is loosely bound to the pellicle
4
Q
What is step 3 of biofilm formation?
A
Bacteria continues to spread throughout the mouth and multiply
5
Q
What is step 4 of biofilm formation?
A
Microcolonies are formed; streptococci secrete a protective layer (also known as the ‘slime layer’)
6
Q
What is step 5 of biofilm formation?
A
Within 2 days microcolonies double in mass and form complex groups with metabolic advantages (plaque is clinically visible at this point)
7
Q
What is step 6 of biofilm formation?
A
Biofilm develops a primitive circulatory system
