Exam 13: Biofilm,calculus,and Stain

Clinical research shows a direct link between one chronic inflammatory condition,such as periodontal disease,to others,such as heart disease,premature birth weight,and diabetes.If a patient has periodontal disease he or she should be referred to a cardiologist.

Which of the following is NOT considered a soft deposit of the oral cavity?

Poor or neglected oral hygiene and diet are the two most common risk factors for caries formation.The regular removal of dental plaque biofilm,which contains the bacteria responsible for caries formation,gingivitis,and periodontitis,is the basis for maintaining oral health.

Supragingival biofilm accumulates on the clinical crown and subgingival biofilm is located within the periodontal pocket or sulcus.Disclosing solution can be used to detect supragingival and subgingival biofilm.

Which of the following can be seen radiographically?

A soft,sticky deposit that adheres to the teeth as a natural occurrence in the oral cavity is

Calculus mineralization takes

Green stain is primarily found on children's

Which of the following is NOT an example of intrinsic endogenous staining?

"Healthy" biofilm contains

Which of the following explorers is suggested for use in a normal sulci or shallow pocket as well as deep periodontal pockets?

Biofilm is an accumulation of microbial cells within an inorganic matrix.Contained within the matrix are polysaccharides,proteins,and DNA.

The manner in which calculus does NOT present itself is

Which of the following bacteria is NOT associated with the acquired pellicle and biofilm formation?

A loosely attached accumulation of bacteria that can be easily removed by mechanical actions is

Most Streptococcus and Actinomyces species metabolize sugars,such as glucose,to lactic acid.Lactic acid is then broken down further into hydrogen,methane,and carbon dioxide by other members of the biofilm.

The most common form of gingivitis found in the general population is

A thin film that coats the tooth immediately upon exposure to saliva is called

Gingivitis is directly associated with
