Community & Public Oral Health Practice Questions

The answer is B.

Representative sampling supports generalization to the target population. Public health measures disease consistently, interprets data at the correct level, and links intervention to need. Surveillance methods, definitions, sampling, reach, equity, and implementation fidelity affect conclusions. Promotion includes social conditions as well as education.

The answer is B.

Recall should respond to disease activity and modifiable risk. Assessment integrates disease indicators, biological and behavioral risks, protective factors, and social context. It guides prevention and recall but is not permanent. Population stratification uses aggregate data for program design and does not replace individual assessment.

The answer is B.

Readiness guides whether to plan a quit attempt or build motivation. Dental visits support screening, advice, quit attempts, and connection to evidence-based care. Communication is nonjudgmental, confidential, and product-specific. Brief intervention respects readiness and safety; dependence treatment or urgent problems may require referral.

The answer is C.

Concrete substitutions are easier to implement than vague advice. Counseling considers frequency, timing, form, and access to free sugars while preserving nutrition and cultural feasibility. Population strategies combine information with healthier defaults, pricing, and availability. Outcomes and equity are monitored rather than assuming education changes exposure.

The answer is B.

Capitation shifts some financial risk toward the provider or organization. Access includes availability, affordability, accommodation, acceptability, and continuity. Delivery and payment models create incentives, but effects depend on implementation. Interventions identify the barrier, involve the community, and track reach, use, quality, and equity.

The answer is C.

Water irrigation can supplement plaque control, especially where access is difficult. Instruction is individualized to anatomy, dexterity, disease, devices, preferences, and routines. Technique is demonstrated and checked rather than merely named. Motivational interviewing uses collaboration, open questions, reflection, and patient-chosen goals instead of confrontation.

The answer is D.

Acid conditioning creates microporosities into which resin penetrates. Effectiveness depends on selecting susceptible fissures, material-specific isolation and placement, and maintaining coverage. Resin usually offers stronger dry-field retention; glass ionomer may be useful when moisture control is difficult, but neither eliminates recall.

The answer is D.

Outcomes represent change rather than resources or activity counts. Planning defines need with community input and data, selects a feasible strategy, assigns resources, implements with fidelity, and evaluates delivery and outcomes. Indicators, comparison, timeframe, reach, unintended effects, cost, and equity should align with the objective.

The answer is C.

Dental fluorosis results from excessive fluoride exposure while enamel is developing, before the affected tooth erupts. Once enamel formation is complete, later fluoride exposure cannot create developmental fluorosis in that tooth, although excessive acute ingestion can still cause toxicity and topical fluoride remains relevant to caries prevention.

The answer is D.

Inputs are resources used to operate the program. Planning defines need with community input and data, selects a feasible strategy, assigns resources, implements with fidelity, and evaluates delivery and outcomes. Indicators, comparison, timeframe, reach, unintended effects, cost, and equity should align with the objective.
