Periodontal Disease Flashcards
What factors determine the reason one patient develops periodontal disease?
Age Species Breed Genetics Chewing behavior Diet Grooming habits Orthodontic occlusion Health status Home Care Frequency of professional dental care Bacterial flora of the oral cavity
What is an inflammation and infection of the tissues surrounding the tooth?
Periodontal disease
Periodontal disease is characterized by what?
The movement of the gingival margin toward the apex and migration of the attached gingiva with associated loss of the periodontal ligament and bone surrounding the tooth
What organs are most susceptible to infection from bacteria from the infected tissues?
Lungs
Kidneys
Liver
What glycoprotein component of saliva attaches to the tooth surface and only takes 20 minutes to form?
Acquired pellicle
About how long after the formation of the pellicle do bacteria start to colonize the tooth surface?
6 to 8 hours
The bacterial layer on the tooth surface is known as what?
Plaque
The bacteria that are attached to the tooth absorb calcium from saliva and become calcified. What is this new substance known as?
Tartar or calculus
The healthy gingival flora is made up of what kind of bacteria?
Gram-positive aerobic bacteria
As periodontal disease progresses, what kind of bacteria begin to colonize the tooth surface?
Gram-negative
What is known as an aggregate of bacterial colonies protected by a polysaccharide complex?
Biofilm
What is important in the control of periodontal disease?
The disruption of biofilm
What species of bacteria is associated with progressive periodontitis in dogs?
Porphyromonas spp.
What is considered the worst type of plaque?
The type that infiltrates the gingiva itself
How does the patient respond to periodontal disease?
The WBCs produce antibodies to stimulate other cells to come attack bacteria
