NEET MDS Public Health Dentistry Flashcards
51 question-and-answer cards covering Public Health Dentistry as it is examined in NEET MDS. 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the Public Health Dentistry deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
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.
What this deck covers
The Public Health Dentistry deck follows the NEET MDS Public Health Dentistry syllabus — 7 chapters and 26 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 7.3 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 175 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.

Yes. The preview here is free to read with no signup, and the full 51-card deck is free inside the Examius app.
What do the Public Health Dentistry cards cover?
They follow the NEET MDS Public Health Dentistry syllabus — 7 chapters and 26 topics — so the questions track what is actually examinable.
How should I use these flashcards?
Read the syllabus first so you know the shape of the subject, then drill the deck. Examius schedules each card with spaced repetition, so cards you keep missing come back sooner and ones you know drift further apart.
