(Blank)
The only indices that is both reversible and irreversible since it measures both perio and gingivitis
DEFT
decayed, extracted, filled, teeth (primary teeth)
This sample reduces chance of bias the most
RANDOM SAMPLE
SURVEY
The Ramfjord teeth commonly used are
3,8,14,19,24,30
The best mechanism to teach oral health to an entire community oF school children is to teach the
TEACHERS
This dental indices does not take into account teeth that have been extracted or exfoliated due to caries
GI
gingival index
0=normal 1=mild inflammation 2=moderate inflammation 3=severe inflammation
The sample where every nth person in line is chosen
SYSTEMATIC SAMPLE
If the mean score of a quiz was 5 with a standard deviation of 1, what does this tell us?
The the average score is 5 and that most scores are between 4 and 6.
Which study is the best way to prevent bias?
DOUBLE BLIND
What is the belief that one's own culture is better than other cultures?
ETHNOCENTRISM
This indices detects the early signs of gingivitis
PS & R (PSR)
periodontal risk score
simple risk assessment tool, 1 measurement per sextant is recorded 0-4
This sampling techniques involves selecting an element according to certain subgroups to diminish the chance of sample fluctuations
STRATEFIED
for example if the population has 200 males and 600 females we might chose to sample 1/4 of each gender so 50 males and 150 females
The number of existing cases of a disease/total population is descriptive of what epidemiological rate?
Prevalence
A Gaussian curve is also known as
BELL CURVE OR NORMAL CURVE
Awareness of cultural differences
CULTURAL COMPETENTCY
Irreversible indices that uses upper case letters for permanent teeth and lower case letters for primary teeth
decayed, missing, filled
JUDGEMENT
A disease that increases in prevalence beyond the expected level is
Epidemic
In a normal curve, the majority of scores fall within __________ standard deviation ranges
+1 and -1
People from different cultures
CULTURAL DIVERSITY
Indices that determines periodontal treatment needs rather than periodontal status
CPITN
Community periodontal index of treatment needs
This sample was chosen because it was easily examined or tested
CONVENIENCE
The study of health and disease in populations is
epidemiology
When more scores fall in the lower range, what kind of curve so you have?
NEGATIVE SKEW
The effective integration of a patient's socioethnocultural background into the dental hygiene process of care
Cross-cultural dental hygiene
What involves the application of statistical tests to the data in order to organize, describe, summarize, and analyze it to answer a research question or test a hypothesis?
DATA ANALYSIS
The mean is commonly considered to be the ________.
THE AVERAGE
What is the first step of the scientific method?
NAME THE PROBLEM OR QUESTION
What is a body of techniques that uses observation, reason, and experimentation to further evidence?
SCIENTIFIC METHOD
The mode is the ________.
THE MOST FREQUENTLY OCCURING VALUE
Which of the following is determined by subtracting the square of the standard deviation?
VARIANCE
Which is determined by subtracting the highest score from the lowest score?
THE RANGE
Organizes data into mutually exclusive categories that are rank-ordered based on some criterion
ORDINAL SCALE
The ratio of the number of deaths from a given disease or condition
MORTALITY
The ratio of "sick" or affected individuals to well individuals
MORBIDITY
