Ch. 21 Indices and Scoring Methods Flashcards
Indices and Scoring methods are used to
Determine and record oral health status of individuals and groups
In clinic, an index (scoring system) for a pt can be used to:
Measure amount of oral disease for purpose of
-Evaluation
-Education
-Motivation
Individual assessment score is used to
Help pt recognize oral problem
Motivate
Evaluate success of individual self care
Clinical trial purpose
Determine baseline data
-affect of agent or procedure on prevention, progression or control of disease
Epidemiologic survey
Study of disease characteristics of populations rather than individuals
Provide info of trends and patterns of oral health and disease in populations
-prevalence
-incidence
-baseline data of existing dental health status in pop.
Community surveillance
Identify factors that affect oral health status of selected population
-assess comm needs
-plan community base health promotion and disease prevention programs
-compare effects and evaluate results
Indices
Index is way of showing clinical observations in numbers
Standardized
Less subjective than word description of condition
Simple index
Measures presence or absence of condition
Ex: Biofilm index-measures biofilm without evaluating its effect on gingiva
Cumulative index
Measures all evidence of condition, past and present
Ex: DMFT for dental caries
Irreversible index
Measure conditions that won’t change
Ex: measure dental caries experience
Reversible index
Measure conditions that can be changed
Ex: indices that measure biofilm
Selection criteria
(Useful and effective index)
-Simple to use and calculate
-Minimal equipment expense and time
-No pt discomfort
-Clear cut criteria, readily understandable
-free from subjective interpretation
-valid and reliable
-statistics from data collection
Biofilm index
Historic name
Purpose
Areas
Evaluate tooth at what third
Score
Historically known as plaque index
Purpose: assess thickness of biofilm at gingival area
4 gingival areas: distal facial mesial and lingual for each tooth
Cervical third only
0 (no biofilm) to 3 (abundance) in pocket or on tooth)
Scoring
Excellent
Good
Fair
Poor
0
0.1-0.9
1-1.9
2-3
Biofilm Control Record (BCR)
Previous name
Purpose
Teeth recorded
Scoring
of surfaces with biofilm / Total # teeth present x # of surfaces (6)
Previous-Plaque Record Score
Record presence of biofilm on individual tooth surfaces to permit visualization while learning bf control
All teeth, 6 areas recorded
DF, F, MF, DL, L, ML
