BDS Public Health Dentistry flashcards — 51 questions with answers
Define "public health" according to C.-E.A. Winslow (1920), the classic definition used in dentistry.
Public health is the science and art of preventing disease, prolonging life, and promoting physical health and efficiency through organized community efforts.
How did the American Board of Dental Public Health define "dental public health"?
The science and art of preventing and controlling dental diseases and promoting dental health through organized community efforts; it serves the community as the patient rather than the individual.
What is the fundamental difference in the "patient" between private dental practice and dental public health?
In private practice the individual is the patient; in dental public health the community (population) is the patient.
Who is regarded as the "Father of Public Health Dentistry"?
Dr. John W. Knutson (with H. Trendley Dean often credited as pioneer of dental public health epidemiology for fluoride/fluorosis work).
What landmark discovery did H. Trendley Dean make, and what index did he develop?
He established the inverse relationship between fluoride in water, dental caries, and mottled enamel (fluorosis), and developed Dean's Fluorosis Index.
When and where was the first community water fluoridation program started?
In 1945 in Grand Rapids, Michigan, USA.
List the three core functions of public health as defined by the Institute of Medicine (1988).
Assessment, Policy Development, and Assurance.
State the classic Epidemiologic Triad of disease causation.
Agent, Host, and Environment (interacting over time).
Define "epidemiology."
The study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to control health problems.
Distinguish between "endemic," "epidemic," and "pandemic."
Endemic = constant/usual presence of a disease in an area; Epidemic = occurrence clearly in excess of expected in a community; Pandemic = an epidemic spread over several countries/continents affecting large populations.
Give the formula for prevalence.
$$\text{Prevalence} = \frac{\text{Number of existing cases at a point in time}}{\text{Total population at that time}}$$
Give the formula for incidence rate (cumulative incidence).
$$\text{Incidence} = \frac{\text{Number of new cases during a period}}{\text{Population at risk during that period}}$$
State the relationship linking prevalence (P), incidence (I), and average duration (D) of a disease.
$P \approx I \times D$ (for a stable, low-prevalence condition).
Write the formula for the incidence density (person-time incidence rate).
$$\text{Incidence density} = \frac{\text{Number of new cases}}{\text{Total person-time at risk}}$$
Define "attack rate" and give its formula.
A cumulative incidence used in outbreaks: $$\text{Attack rate} = \frac{\text{Number of new cases in a period}}{\text{Population at risk at start of period}} \times 100$$
Classify epidemiologic study designs into the two broad categories with examples.
Observational (descriptive: case report/series, cross-sectional; analytical: case-control, cohort) and Experimental/Interventional (randomized controlled trials, community trials).
Which study design is best for rare diseases, and which for rare exposures?
Case-control study is best for rare diseases; cohort study is best for rare exposures.
Which measure of association is calculated in a cohort study versus a case-control study?
Cohort study yields Relative Risk (RR); case-control study yields Odds Ratio (OR).
Write the formula for Relative Risk (RR) using a 2×2 table with cells a, b, c, d.
$$RR = \frac{a/(a+b)}{c/(c+d)}$$
Write the formula for the Odds Ratio (OR) using a 2×2 table with cells a, b, c, d.
$$OR = \frac{a \times d}{b \times c}$$

How is Attributable Risk (AR) calculated, and what does it represent?
$AR = I_{\text{exposed}} - I_{\text{unexposed}}$; it represents the excess risk (incidence) attributable to the exposure.
Define oral disease surveillance.
The ongoing, systematic collection, analysis, interpretation, and dissemination of data on oral health conditions for planning, implementing, and evaluating public health practice.
Name the WHO Oral Health Survey manual used to standardize surveillance and the index for caries it employs.
The WHO "Oral Health Surveys: Basic Methods"; caries is recorded using the DMFT/DMFS index (dft/dfs for primary teeth).
What do the letters in the DMFT index stand for?
D = Decayed, M = Missing (due to caries), F = Filled teeth; DMFT is the sum per individual (max 28 or 32).
Define biostatistics.
The application of statistical methods to biological, medical, and public health data — the science of collecting, organizing, analyzing, and interpreting such data.
Classify data into its main types (scales of measurement).
Qualitative: Nominal and Ordinal; Quantitative: Interval and Ratio (also discrete vs continuous).
Name the three common measures of central tendency and when the median is preferred.
Mean, Median, and Mode; the median is preferred for skewed distributions or data with outliers.
Write the formula for the arithmetic mean of a sample.
$$\bar{x} = \frac{1}{n}\sum_{i=1}^{n} x_i$$
Write the formula for the sample standard deviation.
$$s = \sqrt{\frac{\sum_{i=1}^{n}(x_i - \bar{x})^{2}}{n-1}}$$
Define the coefficient of variation (CV) and give its formula.
A relative measure of dispersion allowing comparison across datasets: $$CV = \frac{s}{\bar{x}} \times 100\%$$
State the key properties of a normal (Gaussian) distribution's empirical rule.
Symmetric bell shape; about $68\%$ of data lie within $\bar{x} \pm 1s$, $95\%$ within $\bar{x} \pm 2s$, and $99.7\%$ within $\bar{x} \pm 3s$.
Differentiate descriptive from inferential statistics.
Descriptive statistics summarize/describe a dataset (mean, SD, tables, graphs); inferential statistics draw conclusions about a population from a sample (estimation, hypothesis testing).
Define null hypothesis ($H_0$) and alternative hypothesis ($H_1$).
$H_0$ states there is no difference/association; $H_1$ states there is a real difference/association.
Define Type I and Type II errors.
Type I error ($\alpha$) = rejecting a true $H_0$ (false positive); Type II error ($\beta$) = failing to reject a false $H_0$ (false negative).
What is statistical "power" and how is it related to $\beta$?
Power is the probability of correctly rejecting a false null hypothesis: $\text{Power} = 1 - \beta$.
What does a p-value represent, and what is the conventional significance threshold?
The probability of obtaining results as extreme as observed if $H_0$ were true; conventionally significant if $p < 0.05$.
Which statistical test compares means of two independent groups, and which compares three or more?
Student's t-test for two groups; ANOVA (analysis of variance) for three or more groups.
Which test is used to compare proportions/categorical data in a contingency table?
The Chi-square ($\chi^{2}$) test.
Name two commonly used statistical software packages in dental public health research.
SPSS and SAS (also R, Stata, and Epi Info).
State Leavell and Clark's three levels of prevention.
Primary prevention (health promotion + specific protection), Secondary prevention (early diagnosis and treatment), and Tertiary prevention (disability limitation and rehabilitation).
Give an oral-health example for each of the three levels of prevention.
Primary: fluoride/sealants/oral hygiene education; Secondary: restorations, scaling for early gingivitis; Tertiary: dentures, prosthetic rehabilitation.
List the main systemic and topical routes of fluoride delivery.
Systemic: water fluoridation, fluoride tablets/drops, salt/milk fluoridation. Topical: toothpaste, mouthrinses, gels, foams, varnishes.
What is the optimal fluoride concentration in community drinking water (traditional value)?
Approximately $1.0\ \text{ppm}$ (0.7–1.2 ppm depending on climate; U.S. now recommends $0.7\ \text{ppm}$).
By what chemical mechanism does fluoride make enamel more caries-resistant?
It converts hydroxyapatite to fluorapatite, which is less acid-soluble: $$\ce{Ca10(PO4)6(OH)2 + 2F^- -> Ca10(PO4)6F2 + 2OH^-}$$
What fluoride concentration is used in professionally applied sodium fluoride varnish?
$5\%$ NaF ($22{,}600\ \text{ppm}$ fluoride).
What are dental (pit-and-fissure) sealants and their primary purpose?
Resin or glass-ionomer materials applied to occlusal pits and fissures to form a physical barrier, preventing bacterial colonization and occlusal caries.
Which teeth and surfaces benefit most from sealant placement, and why?
Occlusal surfaces of permanent molars, because deep pits and fissures are least protected by fluoride and most caries-prone.
Name two evidence-based methods of oral hygiene instruction/toothbrushing taught in oral hygiene education.
The Modified Bass technique (sulcular) and the Fones (circular) technique; supplemented by flossing and the modified Stillman method.
Contrast the Bismarck, Beveridge, and out-of-pocket models of health care systems.
Bismarck = insurance-based, funded by employer/employee premiums; Beveridge = government-funded and provided through taxation (e.g., UK NHS); Out-of-pocket = patients pay directly, common in low-income countries.
List the sequential steps of the health program planning cycle.
Needs assessment, prioritization/objective setting, planning (strategy/resources), implementation, and evaluation (monitoring and feedback) — a continuous cyclical process.
What are the main stages of health policy formulation?
Problem identification/agenda setting, policy formulation, policy adoption (legitimation), implementation, and evaluation.
