NEET MDS Public Health Dentistry flashcards — 51 questions with answers
What is the WHO (1948) definition of health?
A state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.
Define 'Public Health Dentistry' (Dental Public Health) as per Winslow's framework.
The science and art of preventing and controlling dental diseases and promoting dental health through organized community efforts.
What are the three core dimensions of the 'agent-host-environment' epidemiologic triad?
Agent (causative factor, e.g. cariogenic bacteria), Host (susceptible individual), and Environment (external conditions favoring disease) — disease results when they interact in balance favoring causation.
Who is regarded as the 'Father of Public Health Dentistry'?
Dr. John W. Knutson is often credited; however, Dr. H. Trendley Dean is honored as the father of dental epidemiology for his fluorosis/fluoride work.
What landmark observation did H. Trendley Dean make, and what index did he develop?
He linked water fluoride to mottled enamel (dental fluorosis) and the caries-fluoride inverse relationship, and developed Dean's Fluorosis Index (1934/1942).
List the four levels of disease prevention (Leavell & Clark).
Primordial/Primary (health promotion + specific protection), Secondary (early diagnosis & prompt treatment), Tertiary (disability limitation & rehabilitation). Primary prevents occurrence; secondary halts progression; tertiary reduces sequelae.
Differentiate primary, secondary, and tertiary prevention with a dental example each.
Primary: water fluoridation/sealants (prevent caries). Secondary: restoring an early carious lesion (halt progression). Tertiary: prosthetic rehabilitation after tooth loss (restore function).
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.
State the formula for Incidence Rate.
Incidence = (Number of NEW cases during a period / Population at risk during that period) × 1000. It measures the rate of new disease occurrence.
State the formula for Point Prevalence.
Prevalence = (Number of EXISTING cases at a point in time / Total population examined at that time) × 100. It measures the burden of existing disease.
How are prevalence, incidence, and disease duration related?
Prevalence ≈ Incidence × Duration (P = I × D). Prevalence rises with higher incidence or longer disease duration.
Differentiate incidence and prevalence.
Incidence counts only NEW cases over a period (measures risk/rate). Prevalence counts ALL existing cases at a time point (measures burden). Chronic diseases have high prevalence; acute diseases reflect incidence.
What is the difference between a ratio, a proportion, and a rate?
Ratio: one quantity relative to another (a:b), numerator not part of denominator. Proportion: a part of the whole (numerator included in denominator), no time. Rate: a proportion with a specified time component.
Define attack rate and where it is used.
Attack rate = (cases of disease / population at risk) × 100 during an outbreak. It is a cumulative incidence used in epidemics/food-poisoning of limited duration.
Rank the major epidemiologic study designs by strength of evidence.
Strongest to weakest: Systematic review/meta-analysis > RCT > Cohort > Case-control > Cross-sectional > Ecological > Case report/series.
What is a cross-sectional (prevalence) study?
An observational study measuring exposure and outcome simultaneously at one point in time in a population; useful for prevalence but cannot establish temporality/causation.
Compare cohort and case-control studies in direction and measure of association.
Cohort: exposure→outcome (prospective), measures Relative Risk (RR), good for rare exposures. Case-control: outcome→exposure (retrospective), measures Odds Ratio (OR), good for rare diseases.
What is a randomized controlled trial (RCT) and its key strength?
An experimental study where participants are randomly allocated to intervention or control groups. Randomization minimizes confounding and bias, making it the gold standard for causation.
Define relative risk (RR) and its interpretation.
RR = Incidence in exposed / Incidence in unexposed. RR=1 no association; RR>1 exposure increases risk; RR<1 protective effect.
What is oral disease surveillance and its purpose?
The continuous, systematic collection, analysis, and interpretation of oral health data for planning, implementing, and evaluating public health practice (e.g., national oral health surveys).

Which index is the WHO-recommended standard for measuring dental caries experience in permanent teeth?
The DMFT/DMFS index (Decayed, Missing, Filled Teeth/Surfaces). For primary teeth, dmft/dmfs is used.
What does the CPI (Community Periodontal Index) assess and what are its codes?
It assesses periodontal status. Codes: 0=healthy, 1=bleeding, 2=calculus, 3=shallow pocket (4–5mm), 4=deep pocket (≥6mm).
Define biostatistics.
The application of statistical methods to the collection, organization, analysis, and interpretation of data in biology, medicine, and public health.
Differentiate descriptive and inferential statistics.
Descriptive statistics summarize/organize data (mean, SD, frequency). Inferential statistics use sample data to draw conclusions/generalizations about a population (hypothesis testing, confidence intervals).
Name the measures of central tendency and when each is preferred.
Mean (best for symmetric/normal data), Median (best for skewed data/outliers), Mode (best for nominal/categorical data).
Name the common measures of dispersion.
Range, interquartile range, variance, standard deviation, and coefficient of variation. SD is the most commonly used; CV allows comparison between datasets with different units.
Describe the properties of the normal distribution (empirical/68-95-99.7 rule).
Symmetric bell shape, mean=median=mode. ~68% of values lie within ±1 SD, ~95% within ±2 SD (±1.96), and ~99.7% within ±3 SD of the mean.
What is a null hypothesis (H0) and a p-value?
H0 states no difference/association exists. The p-value is the probability of obtaining the observed result if H0 were true; p<0.05 typically rejects H0 (statistically significant).
Differentiate Type I and Type II errors.
Type I (alpha): rejecting a true null hypothesis (false positive). Type II (beta): failing to reject a false null hypothesis (false negative). Power = 1 − beta.
Which statistical test compares means between two independent groups vs more than two groups?
Student's t-test (two groups); ANOVA (three or more groups). For paired data use paired t-test.
When is the Chi-square test used?
To test association between two categorical (qualitative) variables using observed vs expected frequencies in a contingency table.
Differentiate parametric and non-parametric tests with examples.
Parametric tests assume normal distribution & continuous data (t-test, ANOVA, Pearson's r). Non-parametric tests make no distribution assumption, used for ordinal/skewed data (Mann-Whitney U, Wilcoxon, Kruskal-Wallis, Spearman's rho).
Name commonly used statistical software packages in public health research.
SPSS, SAS, STATA, R, Epi Info (WHO/CDC, free), and Microsoft Excel for basic analysis.
What are the modes of systemic vs topical fluoride delivery?
Systemic: water fluoridation, fluoride tablets/drops, salt/milk fluoridation. Topical: fluoride toothpaste, gels, varnishes, mouthrinses, and professionally applied fluorides.
What is the optimal level of fluoride in drinking water (temperate climates)?
Approximately 0.7–1.2 ppm (mg/L), often cited as ~1 ppm; in India, the permissible/optimal level is up to 1.0 ppm (BIS limit 1.0–1.5 ppm).
By what mechanism does fluoride prevent dental caries?
It promotes remineralization, inhibits demineralization, forms acid-resistant fluorapatite, and inhibits bacterial enzymes (enolase) reducing acid production. Post-eruptive topical effect is most important.
What is the certain lethal dose (CLD) and safely tolerated dose (STD) of fluoride?
CLD ≈ 32–64 mg F/kg body weight; STD ≈ 8–16 mg F/kg (one-fourth of CLD). Probably toxic dose (PTD) ≈ 5 mg F/kg.
What are dental sealants and which teeth/surfaces benefit most?
Pit-and-fissure sealants are resin or glass-ionomer materials placed on occlusal pits/fissures to physically block bacteria/substrate. Most beneficial on newly erupted permanent molars.
Compare resin-based and glass-ionomer sealants.
Resin: better retention, requires dry field and acid etching. Glass-ionomer (GIC): releases fluoride, moisture-tolerant, but lower retention; preferred when isolation is difficult or as transitional sealant.
What is the most effective method of mechanical plaque control taught in oral hygiene education?
Toothbrushing (the modified Bass technique is most recommended for gingival sulcus cleaning) plus interdental cleaning with floss/interdental brushes.
What are the building blocks (components) of a health care system per WHO?
Six building blocks: service delivery, health workforce, health information systems, access to essential medicines, financing, and leadership/governance.
Describe the three-tier rural health care structure in India.
Sub-Centre (most peripheral, ~5,000 population), Primary Health Centre (PHC, ~30,000), and Community Health Centre (CHC, ~120,000, first referral with specialists).
What are the steps in health program planning?
Situation/needs analysis → setting priorities & objectives → resource assessment → strategy/plan formulation → implementation → monitoring and evaluation (a cyclical process).
Differentiate health policy and health planning.
Health policy = a statement of goals, priorities and decisions guiding health action (the 'what/why'). Health planning = the process of designing how to achieve those policy goals (the 'how').
Name key leadership styles relevant to public health management.
Autocratic (leader decides), Democratic/Participative (shared decisions), Laissez-faire (hands-off), and Transformational (inspires/motivates change). Effective public health favors participative/transformational styles.
What is the scope of behavioral sciences in dentistry?
Application of psychology, sociology, and anthropology to understand patient behavior, motivation, anxiety, compliance, and the patient-provider relationship to improve oral health outcomes.
What is 'motivational interviewing' in patient communication?
A patient-centered, collaborative counseling style that strengthens a person's own motivation and commitment to behavior change by exploring and resolving ambivalence.
Describe the stages of the Transtheoretical (Stages of Change) Model.
Precontemplation → Contemplation → Preparation → Action → Maintenance (with possible Relapse). Used to tailor oral health behavior-change interventions.
What are the core constructs of the Health Belief Model?
Perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy — determining likelihood of a health-protective behavior.
Why are pediatric and geriatric patients considered priority groups in dental public health?
Children are caries-susceptible and benefit most from preventive programs (sealants/fluoride); the elderly have high rates of root caries, periodontal disease, tooth loss, and xerostomia, often compounded by systemic disease and reduced access.
Define 'special needs dentistry' and 'underserved populations'.
Special needs dentistry serves patients with physical, medical, developmental, or cognitive conditions requiring special care/accommodation. Underserved populations are groups (rural, poor, minorities, disabled) lacking adequate access to dental care due to economic, geographic, or social barriers.
