Foundations of Dental Nursing: Knowledge, Skills and Professional Attributes
The scope of the role
Dental nursing rests on four pillars: clinical support, infection prevention and control (IPC), patient communication, and record keeping. Candidates must be able to name the chain of infection (infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host) and apply standard precautions to every patient regardless of known status. Understand the difference between sterilisation (destroying all micro-organisms including spores), disinfection (reducing pathogens on inanimate objects) and antisepsis (applied to living tissue). Know that instruments are cleaned before sterilisation because debris protects micro-organisms, and that handpieces require flushing and lubrication per manufacturer instructions.
Clinical support and materials
Be confident with the dental charting systems (FDI two-digit, Palmer, and the deciduous quadrant notation), the purpose of rubber dam, matrix bands, and moisture control. Know the properties of common materials: alginate is irreversible hydrocolloid and dimensionally unstable once set, so pour promptly; zinc oxide eugenol is sedative; composite requires a dry field and light curing with eye protection. Understand four-handed dentistry, correct operator and nurse seating, and instrument transfer so that sharp ends are never passed hand-to-hand toward the clinician.
Communication and professionalism
Questions test consent (valid consent is informed, voluntary and given by someone with capacity), confidentiality, and duty of care. Traps include assuming a patient lacks capacity because of age or communication difficulty, and treating a signed form as a substitute for a conversation. Another common trap is confusing the nurse's role in raising a concern with the authority to diagnose.
Worked rule of thumb
If a question describes an instrument that has visible blood and asks the first action, the answer is clean it (with appropriate PPE) before any disinfection or sterilisation step. Sequence: clean, then disinfect or sterilise, then store dry and dated. Never accept "wipe with alcohol and reuse" for a critical item.
