Which of the following epidemiological indices would be BEST for evaluating caries in a group of adults between the ages of 70 and 85 who experience gingival recession, inflammation, and bleeding? DMFT, DMFS, or RCI
What is DMFS?
100
This type of study looks to the past to determine the meaning of past events.
What is a Historical Study?
100
Placing an amalgam restoration after removing caries from the tooth surface is an example of this.
What is secondary prevention?
100
The ratio of the number of deaths from a given disease or health problem to the total number of cases reported.
What is mortality?
100
This is the arithmetic average or scores, the most common measure of central tendency, and is sensitive to extreme values.
What is the mean?
200
Which teeth are the Ramfjord 6?
What are 3, 9, 12, 19, 25, 28
200
These types of studies are designed to describe the extent of a disease or condition within a population and its relationship with other variables. They determine who is getting the disease and where and when the disease is occurring.
What are descriptive studies?
200
This preventive treatment is highly effective in preventing dental caries on surfaces of the teeth that have pits and fissures.
What are dental sealants?
200
The ratio of sick (affected) individuals to well individuals in a community.
What is morbidity?
200
This divides the distribution of scores into two equal parts, 50% will be above, and 50% will be below, and is NOT affected by extreme high or low scores.
What is the median?
300
After the gingival health of Mr. Cook, a 43 year-old business man, is evaluated, his teeth are divided into facial, lingual, distal, and mesial areas and the tissue is assessed for color, contour, bleeding, and ulceration. Which dental index is used?
What is the GI? GI is used MAINLY to evaluate the progressive stages of periodontal disease and attachment loss in major populations.
300
These types of studies test hypotheses to establish cause.
What are experimental studies?
300
The US Center for Disease Control and Prevention recognizes this preventive agent as one of the ten great public health achievements of the twentieth century.
What is community water fluoridation?
300
The number of all existing cases of a disease in a population measured at a given point.
What is Prevalence?
300
The MOST frequently occurring score within the data matrix and affects the skew of the graph.
What is the Mode?
400
This index contains BOTH a debris index and a calculus index which are summed for a single score.
What is OHI-S?
400
When a research study is conducted using a method in which neither the subjects nor the investigators know who is in the control group and who is in the group that receives the experimental treatment.
What is a double blind study?
400
The dental hygiene profession is at the forefront of this movement, and is the only health care profession based exclusively on this.
What is prevention?
400
The number of new cases of a disease in a population over a given period of time.
What is Incidence?
400
This technique refers to a relationship or association between variables that can be measured mathematically. It is perfect at either -1 or +1.
What is correlation?
500
Mr. Black presents with generalized, moderate marginal dental biofilm, inflammation, and bleeding. he indicates that he brushes once a day and flosses when food is caught between his teeth. Which of the following would be BEST for monitoring his oral hygiene performance, indicating specific areas of need? OHI-S, PHP, GI, or O'Leary plaque index?
What is O'Leary's plaque index? This index will allow him to visualize areas of his mouth that need concentration while brushing.
500
In a study where an adult tests a toothbrush type, which one is the independent variable and which one is the dependent variable?
Independent variable: person Dependent variable: Toothbrush
