periodontal indices Flashcards
periodontal indices
- extent and severity index
- periodontal index system
- periodontal disease index system
- the CPITN
- periodontal screening and recording (PSR)
extent and severity index defines disease as _____
attachment loss > 1 mm
the proportion/percentage of tooth sites in a patient showing signs of destructive periodontitis
extent
amount of attachment loss at the diseased sites, expressed as a mean value
severity
unlike other periodontal disease indices, ESI describes the _____
distribution of disease
periodontal index system (PI) was intended to estimate the extent of deeper periodontal disease than PMA index by measuring:
- the presence/absence of gingival inflammation and its severity
- pocket formation
- masticatory function
since PI measures both reversible and irreversible aspects of periodontal disease, it is an _____ with a _____
epidemiologic index; true biologic gradient
in the PI system, all teeth are examined and the _____ of each tooth is inspected ____ and given a score
circumference; visually
5 components of the periodontal disease index system (PDI)
- gingival status
- crevicular measurements
- periodontal disease index
- plaque criteria
- calculus criteria
in the PDI system, ___ areas per tooth are examined using ____
four; a probe
primarily designed to assess periodontal treatment needs in under served parts of the world; uses a specially designed probe
CPITN
the 2 components of CPITN are:
periodontal status and treatment needs
a rapid and effective way to screen patients for periodontal diseases and summarizes necessary information with minimum documentation
PSR
PSR benefits include:
early detection, speed, and simplicity
cost effectiveness, recording ease, and risk management
documentation for PSR requires the recording of ___ numerical values, one for each ____ of the mouth
6; sextant
