Local Contributing Factors to Periodontal Disease Flashcards
What is the definition of predisposing factor?
Factors that contribute to periodontal disease, accelerate disease progression, and contribute to the disease.
What common factors cause plaque retention?
Interproximal contact
Cervical enamel projections
Bifurcation ridge
Root anatomy
cemental tears
Enamel pearls
Accessory root canals
Root proximity
Adjacent teeth
Caries
Implants
What kind of contacts lead to plaque retention?
Open contact
Uneven marginal ridge
Opposite cusp
RESTORE CONTACT TO FIX THIS PROBLEM
What are cervical enamel projections?
Marks on the tooth caused by failed amelogenesis
Wedge extension of enamel
These deficiencies are usually seen in lower molars and are plaque retentive
What is a bifurcation ridge?
An excrescence of cementum that runs along the roots and makes debridement difficult
What are some important variations in root anatomy that can influence treatment?
Palato gingival groove
Root trunk length
Inter-root separation
Root fusion
Root concavities
Root length
How does root trunk length affect tooth health?
If short furcation can be exposed easily
If long furcation less often gets exposed
What are cemental tears?
Deattachment of cementum from the root caused by trauma and associated with local bone loss.
How are cemental tears treated?
Surgically
What are enamel pearls?
Ectopic enamel that can lead to plaque retention
What should be done for treatment of enamel pearls?
Removal and root debridement
What are accessory root canals?
An endo perio communication
How are accessory root canals treated?
Endo treatment followed by perio assessment
How does close root proximity retain plaque?
Thin bone septum makes it difficult to remove plaque
What restorative factors can lead to plaque retention?
Overhangs
Margin location
Crown contours
Pontic form
Restorative materials
