National Board Dental Examination / Integrated National Board Dental Examination (INBDE) Ethics, Behavioral Science, and Practice of Dentistry Syllabus

In motivational interviewing, what is the difference between 'change talk' and 'sustain talk'?

Change talk is the patient's own statements favoring behavior change (a positive sign); sustain talk is statements favoring the status quo. The clinician aims to elicit and reinforce change talk.

What is the 'tell-show-do' technique in behavioral management?

A behavior-shaping method (common in pediatrics) where the clinician explains a procedure (tell), demonstrates it (show), then performs it (do) to reduce fear by familiarizing the patient.

What is the difference between dental fear, dental anxiety, and dental phobia?

Fear is a reaction to a known present threat; anxiety is apprehension about an anticipated/uncertain threat; phobia is a persistent, excessive, irrational fear causing avoidance (a diagnosable disorder).

What is 'systematic desensitization' for managing dental anxiety?

A behavioral technique that gradually exposes the patient to feared stimuli in increasing increments while pairing exposure with relaxation, reducing the anxiety response over time.

Define 'cultural competence' in healthcare.

The ability of providers and systems to deliver effective care that respects and responds to patients' cultural and linguistic needs, beliefs, and practices.

What is 'health literacy'?

The degree to which individuals can obtain, process, and understand basic health information and services needed to make appropriate health decisions.

What is the 'teach-back' method and why is it used?

Asking patients to restate instructions in their own words to confirm understanding. It verifies comprehension and improves adherence, especially with low health literacy.

What are common signs that should raise suspicion of child abuse during a dental exam?

Injuries inconsistent with the history, multiple injuries at different healing stages, bruising/trauma to the head/face/mouth, torn labial frenum, bilateral/patterned injuries, and delayed care-seeking.

What is a dentist's legal obligation when child abuse or neglect is suspected?

Dentists are mandated reporters and must report reasonable suspicion to the appropriate child protective/legal authorities; proof is not required, and good-faith reporting is generally legally protected.

What is 'dental neglect'?

The willful failure of a parent/guardian to seek and follow through with treatment necessary to ensure a level of oral health essential for adequate function and freedom from pain and infection.

How is 'dental public health' defined as a specialty?

The science and art of preventing and controlling dental disease and promoting oral health through organized community efforts; it targets populations rather than individuals.

What are the levels of prevention (primary, secondary, tertiary) with a dental example of each?

Primary = prevent disease before onset (fluoridation, sealants); Secondary = early detection/treatment (caries detection, fillings); Tertiary = limit disability/restore function (dentures, rehabilitation).

What is the optimal concentration of fluoride in community water fluoridation recommended by the U.S. PHS (2015)?

0.7 mg/L (0.7 ppm).

In epidemiology, what is the difference between incidence and prevalence?

Incidence = number of NEW cases in a population over a time period (measures risk/rate of new disease); Prevalence = total EXISTING cases at a point/period (measures disease burden).

Define sensitivity and specificity of a diagnostic test.

Sensitivity = the proportion of truly diseased people who test positive (true positive rate). Specificity = the proportion of truly healthy people who test negative (true negative rate).

What do positive predictive value (PPV) and negative predictive value (NPV) measure?

PPV = probability a person with a positive test truly has the disease; NPV = probability a person with a negative test truly does not. Both depend on disease prevalence.

What is the difference between a case-control study and a cohort study?

Case-control starts with outcome (diseased vs. not) and looks back at exposures (retrospective, yields odds ratio); cohort starts with exposure status and follows forward for outcomes (yields relative risk).

What is the difference between mean, median, and mode?

Mean = arithmetic average; Median = middle value when data are ordered (best for skewed data); Mode = most frequently occurring value.

What does a p-value < 0.05 indicate in a study?

There is less than a 5% probability the observed result occurred by chance if the null hypothesis were true; results are conventionally considered statistically significant and the null hypothesis is rejected.

What is the difference between a Type I and Type II error?

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.

What are the levels of the evidence-based dentistry hierarchy from highest to lowest?

Systematic reviews/meta-analyses of RCTs > individual RCTs > cohort studies > case-control studies > case series/reports > expert opinion. (Filtered evidence ranks above unfiltered.)

What are the three components of evidence-based dentistry (EBD)?

Best available scientific evidence, the clinician's expertise, and the patient's needs and preferences.

What does the PICO format used to frame a clinical question stand for?

Patient/Population/Problem, Intervention, Comparison, and Outcome.

What does the DMFT/dmft index measure in oral health surveillance?

Caries experience: the number of Decayed, Missing, and Filled Teeth. Uppercase (DMFT) is for permanent teeth; lowercase (dmft) is for primary teeth.

What does a CPITN/CPI probe and index assess?

The Community Periodontal Index assesses periodontal treatment needs by scoring sextants for gingival bleeding, calculus, and pocket depth using a specialized WHO probe.

What does a high score on a plaque index or gingival index indicate?

A plaque index measures the amount of dental biofilm present; a gingival index (e.g., Löe-Silness) measures the severity of gingival inflammation. Higher scores indicate worse oral hygiene/inflammation.

What does OSHA's Bloodborne Pathogens Standard require of dental employers?

An exposure control plan, engineering/work-practice controls, free hepatitis B vaccination, PPE, post-exposure follow-up, hazard communication, and training—to protect workers from bloodborne pathogens.

What is the most common work-related musculoskeletal problem among dentists, and a key ergonomic countermeasure?

Musculoskeletal disorders of the neck, back, and shoulders from prolonged static/awkward posture. Countermeasures include neutral posture, proper patient/operator positioning, magnification, and frequent micro-breaks.

What is the standard ergonomic 'clock' positioning concept for a right-handed dentist?

The operator works around the patient's head using clock positions—roughly 9–12 o'clock for a right-handed dentist (8–4 range)—to maintain direct vision and neutral posture.

What are 'standard precautions' in infection control?

Treating all blood, body fluids, secretions, non-intact skin, and mucous membranes as potentially infectious for every patient—using hand hygiene, PPE, and safe practices regardless of known infection status.

What is the difference between sterilization and disinfection?

Sterilization destroys ALL microorganisms including bacterial spores (e.g., autoclaving); disinfection eliminates most pathogens but not necessarily all spores (used on surfaces/heat-sensitive items).

What does the Spaulding classification (critical, semi-critical, non-critical) determine in dental instrument processing?

The required level of reprocessing by infection risk: Critical items (penetrate tissue/bone, e.g., scalers, forceps) must be sterilized; Semi-critical items (contact mucosa, e.g., mirrors, handpieces) sterilized or high-level disinfected; Non-critical items (contact intact skin) need low/intermediate disinfection.

What biological indicator confirms autoclave sterilization is effective?

A spore test (biological indicator) using Geobacillus stearothermophilus spores; failure of the spores to grow after processing confirms sterilization. CDC recommends weekly testing.

What are the standard autoclave (steam sterilization) parameters?

Approximately 121°C (250°F) at 15 psi for 15–30 minutes, or a flash/higher-temperature cycle ~132°C (270°F) for a shorter time, depending on load and wrapping.

What is the immediate first step after a percutaneous (needlestick) exposure to blood?

Wash the wound with soap and water (flush mucous membranes with water/saline), then report the exposure and initiate the post-exposure evaluation protocol (source/recipient testing, possible PEP).

What is the purpose of quality assurance (QA) in a dental practice?

A systematic, ongoing process of monitoring and evaluating care against established standards to identify deficiencies and continuously improve patient outcomes and safety.

What is 'risk management' in dentistry?

Proactive identification, assessment, and reduction of liability and patient-harm risks through informed consent, thorough documentation, good communication, and adherence to standards of care.

What does the Plan-Do-Study-Act (PDSA) cycle accomplish in quality improvement?

It is an iterative four-step model for testing and implementing change: Plan a change, Do (test it on a small scale), Study the results, and Act (adopt, adjust, or abandon).

What is interprofessional collaboration in healthcare, and why does it matter in dentistry?

Multiple health professions working together with patients and families to deliver coordinated, comprehensive care. It matters because oral health is linked to systemic conditions (e.g., diabetes, cardiovascular disease), improving outcomes.

What essential information should a dental referral letter to a specialist include?

Patient identification, reason for referral, relevant medical/dental history, current findings, radiographs/records, the specific service requested, and the referring dentist's contact information.
