DANB credential history

DANB launched CDIPC after the COVID-19 pandemic to recognize the dental practice Infection Control Coordinator (ICC) role required by CDC's 2016 dental infection prevention summary. The exam covers foundational IPC concepts, the dental regulatory framework (CDC, OSHA, EPA, FDA, state dental boards), hand hygiene, PPE selection and donning/doffing, sterilization and disinfection per Spaulding classification, surface and equipment management, dental unit waterline quality (CDC ≤500 CFU/mL), sharps safety and bloodborne pathogen exposure response, respiratory protection, and program/policy/training oversight.

1Which element of the chain of infection is BEST described as the location where the pathogen lives, multiplies, and is available for transmission?

A.Portal of exit

B.Reservoir

C.Susceptible host

D.Mode of transmission

Explanation: The reservoir is where the pathogen survives and multiplies (humans, animals, water, equipment). It is the second link in the chain of infection.

2A patient sneezes during an exam, releasing large respiratory particles that travel approximately 3 feet and land on the assistant's face. Which mode of transmission is this?

A.Airborne transmission

B.Vector-borne transmission

C.Droplet transmission

D.Vehicle transmission

Explanation: Droplet transmission involves large particles (>5 microns) that travel short distances (typically within 3-6 feet) before settling. Influenza, pertussis, and meningococcus spread this way.

3Which statement BEST describes Standard Precautions as defined by CDC?

A.Apply only when a patient has a confirmed bloodborne infection

B.Apply only to procedures involving visible blood

C.Apply to ALL patients regardless of suspected or confirmed infection status

D.Apply only when treating immunocompromised patients

Explanation: Standard Precautions assume that blood and body fluids from any patient may contain transmissible pathogens. They apply to every patient encounter regardless of diagnosis.

4A patient with active pulmonary tuberculosis requires an emergency dental procedure. Which Transmission-Based Precaution category applies?

A.Contact Precautions

B.Droplet Precautions

C.Airborne Precautions

D.Standard Precautions only

Explanation: Active pulmonary TB requires Airborne Precautions: airborne infection isolation room (AIIR), N95 or higher respirator for staff, and the patient should defer elective dental care until non-infectious.

5Which sequence correctly orders the chain of infection from start to end?

A.Reservoir → Agent → Portal of exit → Mode of transmission → Portal of entry → Susceptible host

B.Agent → Reservoir → Portal of exit → Mode of transmission → Portal of entry → Susceptible host

C.Susceptible host → Portal of entry → Mode of transmission → Reservoir → Agent → Portal of exit

D.Agent → Portal of entry → Reservoir → Mode of transmission → Portal of exit → Susceptible host

Explanation: The standard chain of infection is: infectious agent → reservoir → portal of exit → mode of transmission → portal of entry → susceptible host. Breaking any link interrupts transmission.

6An assistant develops a herpetic whitlow on a finger from contact with an infected patient's oral lesions during treatment. Which mode of transmission is this?

A.Direct contact

B.Indirect contact

C.Droplet

D.Vehicle

Explanation: Direct contact transmission occurs when an infectious agent transfers from an infected person directly to a susceptible host through skin-to-skin contact, which is how herpetic whitlow is acquired.

7Which body fluid is NOT considered Other Potentially Infectious Material (OPIM) under OSHA's Bloodborne Pathogens standard?

A.Saliva in dental procedures

B.Cerebrospinal fluid

C.Sweat (without visible blood)

D.Synovial fluid

Explanation: OSHA explicitly excludes sweat, tears, saliva (in non-dental settings), urine, vomitus, feces, and nasal secretions from OPIM unless they contain visible blood. Saliva in DENTAL procedures is OPIM.

8A patient with suspected measles needs urgent dental treatment. Which respiratory protection is MINIMUM required for the operatory team?

A.Level 3 ASTM surgical mask

B.N95 filtering facepiece respirator (fit-tested)

C.Surgical mask with face shield

D.Half-face elastomeric respirator with P100 cartridge only

Explanation: Measles spreads via airborne route. CDC requires a fit-tested N95 (or higher: PAPR, elastomeric N95+) for staff. Surgical masks do not provide adequate airborne protection.

9Which is the MOST important reason dental healthcare personnel must understand the chain of infection?

A.To assign blame after exposure incidents

B.To identify intervention points where transmission can be interrupted

C.To diagnose patient infections

D.To determine billing codes for infectious patients

Explanation: The chain of infection model identifies six links; breaking any one link prevents transmission. This guides selection of hand hygiene, PPE, sterilization, and engineering controls.

10A patient is identified as immunocompromised due to recent chemotherapy. In the chain of infection, which link is MOST relevant to their increased dental infection risk?

A.Reservoir

B.Mode of transmission

C.Portal of exit

D.Susceptible host

Explanation: Immunocompromised status directly affects the susceptible host link — host defenses (immune system) are reduced, increasing the probability that exposure will lead to infection.

About the DANB CDIPC Exam

The DANB CDIPC (Certified in Dental Infection Prevention and Control) credential validates the dental practice Infection Control Coordinator (ICC) on CDC's 2016 Summary of Infection Prevention Practices in Dental Settings, OSHA Bloodborne Pathogens and Hazard Communication standards, instrument processing per Spaulding classification, dental unit waterline management, and program-level infection prevention policies.

DANB CDIPC Study Tips from Top Performers

1Read the CDC 2016 Summary of Infection Prevention Practices in Dental Settings cover-to-cover — it is the single most cited source

2Memorize Spaulding classification (critical/semi-critical/non-critical) and map dental instruments to each tier

3Drill OSHA BBP 1910.1030 specifics: Exposure Control Plan elements, sharps log requirements, HBV vaccination timeline, post-exposure follow-up schedule

4Master DUWL: CDC ≤500 CFU/mL standard, treatment products (Sterisil, ICX, Citrisil), anti-retraction valves, shocking procedure

5Practice donning/doffing sequences — doffing order is the most-tested PPE topic

Frequently Asked Questions

What is the DANB CDIPC credential?

CDIPC stands for Certified in Dental Infection Prevention and Control. DANB launched it to credential the practice-level Infection Control Coordinator (ICC) role required by CDC's 2016 Summary of Infection Prevention Practices in Dental Settings.

How many questions are on the DANB CDIPC exam?

DANB lists 100 multiple-choice items on the CDIPC exam with a 120-minute testing window, delivered through Pearson VUE.

What score is needed to pass DANB CDIPC?

DANB score reports use a scaled 100-900 score range with 400 as the passing standard, the same scoring scale DANB uses for ICE, CDA, and other component exams.

How much does DANB CDIPC cost in 2026?

The DANB application packet lists CDIPC at $325 for traditional applicants and $320 for active military applicants. Confirm current fees on DANB's exam page before applying.

Who should pursue DANB CDIPC?

DANB targets CDIPC at dental Infection Control Coordinators (ICCs) — typically experienced assistants, hygienists, office managers, or dentists who oversee the practice's written IPC program, training, and OSHA compliance.

How is CDIPC different from DANB ICE?

ICE is a 75-question component exam covering chairside infection prevention. CDIPC is a 100-question stand-alone credential covering ICC-level program oversight: written plans, OSHA compliance documentation, waterline programs, exposure response, and staff training audits.
