DNH 141- CH21 Test With Complete Solution Which of the following microorganisms provide the matrix for the mature mineralization of calculus? - Answer Filamentous organisms Heavy calculus formers have higher levels of parotid pyrophosphate than do light calculus formers. - Answer false Which substance is considered an inhibitor of calcification and can be found in anitcalculus dentrifice? - Answer pyrophosphate Calculus forms in layers. - Answer true The outer surface of the subgingival calculus lies in contact with - Answer the epithelial lining Calculus mineralization can begin in as little as ____ when oral hygiene is neglected. - Answer 24-48 hours The presence of calculus influences the progression of gingivitis because the bacteria perpetuate the gingival tissue supragingivally. - Answer The statemen t and the reason are both correct and related Which of the following can be used to detect small spicules of calculus? Se lect two - Answer Explorer Compressed Air White, creamy, or gray; may be stained by extrinsic factors including food and tobacco - Answer Surpragingival calculus Calculus that attaches to acquired pellicle is easier to remove because the calculus does not penetrate the acquired pellicle. - Answer The statemen t and the reason are both correct and related. Calculus plays role in the development of periodontal disease. Subgingival calculus can be present without the presence supragingival deposits. - Answer Both statements are true. Calculus forms on a removable prostheses because the prostheses only has a smooth surface - Answer The statement is correct, but the reason is not corr ect. Subgingival calculus is always covered by active biofilm bacteria. The bacteria promotes periodontitis because it is in contact with the pocket epitheliu m. - Answer BOTH STATEMENTS ARE TRUE Which of the following is a characteristic of subgingival calculus? - Answer Stains derived from blood pigments of diseased tissue Would you expect the calculus deposits on the proximal surfaces to be supragingival or subgingival deposits? - Answer subgingival The mineralization of calculus is comparable to the mineralization in - Answer enamel The most frequent sites for supragingival calculus to form include which of the following?

Therefore, a dentifrice containing pyrophosphate is not recommended. - Answer The statement is correct, but the reason is no t correct. Radiographs are important in the detection of calculus. Highly mineralized proximal calculus may be detected on radiographs. - Answer The first statemen t is false; the second statement is true. Radiographs are not the most important factor in the detection of calculu s. Highly mineralized proximal calculus may be detected on radiographs. - Answer both statements are true Supragingival calculus can be found on - Answer the clinical crown. removable prostheses. implants. Mineralization of supragingival and subgingival calculus is essentially the same. The source of the elements for mineralization is the same. - Answer The first statement is true; the second statement is false. Saliva is the source of elements for - Answer supragingiva calculus The pellicle lies between the dental biofilm and the tooth surface, theref ore the pellicle must mineralize to create a firm bond of the calculus to the too th surface.The benefits of buying summaries with Stuvia:
