Exam 5: Calculus and Other Disease-Associated Factors

Heavy calculus formers have higher levels of ________________ in their saliva,whereas light calculus formers have higher levels of _______________ secreted from their parotid.

Radiographic images should be used in conjunction with the explorer to detect subcalculus.Radiographic images are an accurate measure of the extent of subcalculus on the tooth surface.

Subgingival calculus is associated with which of the following?

The risk of severe periodontal disease is increased by approximately what amount for those who smoke tobacco products?

Supragingival calculus and subgingival calculus differ in _____________,____________,and ____________.

Calculus becomes firmly attached to the tooth surfaces through which mechanism(s)?

The composition of the bacterial plaque biofilm changes when a child is in orthodontic brackets and bands.

Hydroxyapatite is the predominant crystal type in mature supragingival calculus.Approximately 80% of supragingival calculus is made up of minerals.

The risk of periodontal disease is increased for moderate drinkers.The protective effects of alcohol consumption and the presence of social habits must be considered when discussing these risk indicators with patients.

How long does it take for plaque biofilm to begin to mineralize?

Calculus is always found in the presence of bacterial plaque biofilm.

Spotting a patient who is a mouth breather is fairly easy.Which of the following conditions will be observed in this patient?

The patient must be actively involved in maintaining their gingival health.Daily plaque control helps a patient maintain gingival health.

Subgingival calculus is essentially found in all periodontal pockets.Bacterial plaque biofilm causes greater periodontal disease progression than subgingival calculus that is covered in bacterial plaque biofilm.

All of the following are recommended regarding the margins of restorations except:

Subgingival calculus is made up of crystals that can grow into cemental irregularities and bond to tooth structure.These qualities are important to understand because they explain why:

Malocclusion can cause periodontal disease because it can make homecare more difficult for the patient,change the embrasure space,and make it more difficult for the hygienist to débride the teeth.

Which of the following is the best method to detect overhanging amalgam restorations?

Orthodontic bands and brackets are associated with which of the following conditions?

Significant tissue improvement occurs with calculus removal.Poorly contoured restorations do not affect tissue health.
