Risks for Perio Disease 2: Local Factors Flashcards
What are some local risk factors?
Calculus Tooth Morphology Gingival form Caries Restorations Interproximal contact
What is a plaque retentive local factor?
A risk factor that encourages biofilm accumulation and maturation and impedes effective oral hygiene practices
Why are local factors so important to not during a perio exam?
Perio diseases are mixed infections associated with specific bacteria so identifying local risk factors might give insight as to where perio disease might be more likely
What is calculus
mineralized bacterial plaque
Why is calculus a plaque retentive factor?
It has a rough surface and is always covered in unmineralized plaque
What is the link between calculus and perio disease?
Populations with high prevalence for calculus have a high prevalence for attachment loss
What are 5 plaque retentive risk factors associated with tooth morphology?
Poorly contoured restorations Fractures Root concavities Furcations Enamel pearls
How is gingival form a local risk factor?
Form can impeded plaque removal
How is gingival form repaired?
Gingivectomy surgery
What can cause or contribute to an enlarged gingival form?
Biofilm
Medications
Trauma
How are caries a local plaque retentive risk factor?
Caries near the gingival margin impede oral hygiene and can “hold” biofilm close to the gingiva
What are the two categories of risk factor associated with dental restorations?
Quality
Location
What are two examples of a quality issue with restorations?
Overhangs
Irregularities
What are two examples of location issue with restorations?
Supragingival
Subgingival
What does an open interproximal contact due to periodontal disease risk?
Increases it greatly due to food impaction and advanced pocket depth.
What is a plunger cusp?
An over-erupted cusp that lies directly over an interproximal contact
What problems do plunger cusps usually cause?
Food impaction
Perio pocket formation
Tooth fracture
Why are deep perio pockets a perio disease plaque retentive risk factor?
Deep pockets harbor microbes that can invoke inflammatory responses
What are some other local risk factors that aren’t necessarily plaque retentive?
Root proximity
Occlusion
Impacted wisdom teeth
Endo-perio lesions
