Flashcards in Perio Ch 7&8 Deck (17):
Do local contributing factors initiate periodontal disease?
No, it contributes to the process already initiated and may increase the risk of developing the disease
What are the 3 ways local contributing factors increase the risk of disease?
1. Increase biofilm retention (rough edge on a restoration)
2. Increase biofilm pathogenicity (biofilm- covered calculus deposit)
3. Cause direct damage to the periodontium (heavy chewing forces on tooth)
2 factors that increase biofilm retention?
3 modes of calculus attachment to the tooth
1. Attach to pellicle (most common means of attachment to surface of the tooth) easy removal
2. Attach to tooth irregularities (difficult to remove due to deposits in tooth defects)
3. Attach by direct contact to the tooth (firmly interlocked and difficult to remove)
What is the ability of the bacteria in biofilm to produce periodontal disease?
What are the causes that cause direct damage to the periodontium?
Local contributing factors are?
Unintentionally caused by dental work
What position do you measure occlusion in?
What is any deviation from normal termed?
Physiologic occlusion is what?
Not ideal but is symptom free and adapts to deviated occlusion
What is pathologic occlusion?
Dentition shows signs and the other has symptom of occlusal disease
Para functional occlusal forces
Results from tooth to tooth contact when not in the act of eating
Ex: clenching, bruxism, nail biting, tongue thrusting, thumb sucking, pencil chewing
Is gingiva affected by excessive occlusal forces?
Does occlusal trauma alone cause gingivitis, periodontitis, pocket formation or gingival recession?
Signs of trauma from occlusion?
- tooth mobility
- sensitivity to pressure
- migration of teeth
- enlarged, funnel shaped PDL space
- alveolar bone resorption
