Final; Efficacy of Diagnostic Techniques for Periodontal Disease Flashcards
Periodontal disease is currently diagnosed almost entirely on the basis of what
its clinical manifestations; gingival inflammation, periodontal probing, tooth mobility, furcation involvement, radiographs for bone loss
What are the two traditionally used diagnostic procedures for diagnosing periodontal disease
periodontal examination and radiographs
What three tests are not routinely used in clinical practice
microbiologic testing
assessment of the host response
genetic analysis
What are some limitations of probe penetration
lack of sensitivity and reproducibility
probing depth; inflammation, technique, subgingival calculus
What are some limitations of diagnosing CAL
poor reliability and reproducibility
limited practical value
What are some limitations of radiographic examinations
limited sensitivity in small bone change; can only be identified by eye after 30% to 50% of the bone mineral has been lost
no value in evaluating disease activity or progression
What is the mechanism of ultrasonic periodontal probing
it uses a hollow tapered tip that is filled with water for coupling of the ultrasonic beam into the tissues (non-invasive)
This has been introduced for the detection of periodontal defects in in-vitro settings, especially for bony defects, periodontal cysts, furcation defects, and thickness of palatal masticatory mucosa
CBCT
This quality of a diagnostic test refers to the probability of the test being positive when the disease is truly present
sensitivity
This quality of a diagnostic test refers to the probability of the test being negative when the disease is not present
specificity
This type of microbiologic testing is the gold standard method which assess for antibiotic susceptibility of microbes but has low sensitivity
bacterial culturing
This type of microbiologic testing depicts the morphology and motility of bacteria in a plaque sample
direct microscopy
This type of microbiologic testing uses Abs that target sepcific bacterial Ag, flow cytomerty, ELISA, and latex agglutination
immunodiagnositc methods
This type of microbiologic testing identifies common tyrpsin-like enzymes in periodontal pathogens
enzymatic methods
This type of microbiologic testing analyzes DNA, RNA, and structure and function or proteins from target microorganisms
molecular biology techniques
