Professional Practice

Study guide

Unit 1 is the largest unit in the Diploma and the one the others lean on. It is less about clinical technique than about the framework a registered professional works inside: who regulates you, what you may and may not do, how the surgery stays safe and clean, and what happens when something goes wrong.

The GDC, registration and scope of practice

The General Dental Council registers the whole dental team and publishes the Standards for the Dental Team, built around nine principles. Registration is personal: it is yours to maintain, not your employer’s.

• The nine principles of the Standards for the Dental Team are the framework the GDC judges conduct against — know that there are nine and what they broadly cover.
• Scope of practice defines what a dental nurse is trained and competent to do; working outside it puts registration at risk even when a colleague asks you to.
• Fitness to practise concerns whether a registrant is safe to work, and can be affected by health, conduct or competence.
• Indemnity and registration are separate requirements, and both must be in place to practise.

Infection prevention, decontamination and equipment

Decontamination is the most heavily tested practical area in this unit. Learn the stages in order and what each one achieves, because questions often hinge on the difference between cleaning, disinfection and sterilisation.

• Cleaning removes visible contamination, disinfection reduces microorganisms, and sterilisation destroys all of them including spores — they are not interchangeable terms.
• Instruments follow a one-way route from dirty to clean; the layout of a decontamination room is designed to prevent recontamination.
• Autoclaves are tested and their cycles recorded — the record is part of the evidence that the process works.
• Personal protective equipment protects both the patient and the operator, and is changed between patients.

Health, safety and ionising radiation

Health and safety legislation is the single largest sub-topic in this unit. You are not expected to recite statutes, but you are expected to know which duty sits with whom.

• Employers carry duties for a safe workplace; employees carry duties to work safely and to report hazards. Most questions test that split.
• Hazardous substances in a practice are assessed and controlled, with information available to staff.
• Ionising radiation is separately regulated, with defined roles and justification for every exposure — a radiograph is taken because it will change the patient’s management, not routinely.
• Accidents and incidents are recorded, and certain categories are reportable beyond the practice.

Consent, records, confidentiality and candour

This cluster is where professional practice meets law. Questions here reward precision about what makes consent valid and what a patient is entitled to.

• Valid consent is voluntary, informed and given by someone with capacity — all three, every time.
• Records are a clinical and legal document: contemporaneous, accurate, and retained for defined periods.
• Confidentiality is a professional duty with narrow, defined exceptions; sharing information needs a lawful basis.
• The duty of candour requires being open when something goes wrong, including apologising — separate from, and in addition to, the complaints procedure.
• Safeguarding concerns and concerns about a colleague both have escalation routes, and raising them is a professional obligation rather than an option.

In the exam Expect scenario questions that put a duty in conflict with convenience — an employer asking for something outside your scope, a colleague cutting a decontamination corner, a patient asking for records. The right answer is almost always the one that names the correct duty holder and the correct escalation route.
