Unit 12: Supporting with extraction and minor oral surgery procedures
This unit ensures dental nurses understand the principles and procedures of dental extractions and minor oral surgery, enabling them to provide competent clinical support. It covers the preparation of instruments, materials and the surgery environment, alongside the management of patients before, during and after simple and surgical extraction procedures. The knowledge and skills developed here are directly applied in practice to maintain patient safety, assist the clinician effectively, and ensure cross-infection control.
Assessment criteria
Topic Overview
The NEBDN Level 3 National Diploma in Dental Nursing (Integrated Apprenticeship) (RQF) is a comprehensive qualification that combines practical workplace training with theoretical knowledge. It covers all aspects of dental nursing, including infection control, patient care, radiography, and assisting with a wide range of dental procedures. This diploma is essential for those seeking to become qualified dental nurses in the UK, as it meets the General Dental Council's (GDC) requirements for registration.
The course is structured around core units such as 'The Role of the Dental Nurse', 'Health and Safety in the Dental Workplace', and 'Assisting in the Treatment of Patients'. Students learn through a blend of online learning, college attendance, and on-the-job training in a dental practice. The integrated apprenticeship model ensures that learners gain real-world experience while studying, making them job-ready upon completion.
This qualification is vital for maintaining high standards of patient care and safety in dental practices. It equips students with the skills to support dentists effectively, manage instruments and materials, and communicate with patients. By the end of the course, students are prepared for the NEBDN final examination and can apply for GDC registration, opening doors to a rewarding career in dental nursing.
Key Concepts
Core ideas you must understand for this topic
- →Infection control: Understanding standard precautions, decontamination of instruments, and disposal of clinical waste to prevent cross-infection.
- →Patient care: Managing patient anxiety, obtaining consent, and providing chairside support during treatments like fillings, extractions, and root canals.
- →Radiography: Safely taking and processing dental X-rays, understanding radiation protection, and interpreting common radiographic errors.
- →Four-handed dentistry: Efficiently assisting the dentist by anticipating needs, passing instruments correctly, and maintaining a clear field of view.
- →Medical emergencies: Recognising signs of anaphylaxis, cardiac arrest, or hypoglycaemia, and knowing how to use emergency drugs and equipment.
Learning Objectives
What you need to know and understand
- 12.1 Understand the principles and procedures of extractions and minor oral surgery procedures 12.2 Be able to provide appropriate support to the clinician and patient during simple and surgical extraction procedures
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate identification and preparation of extraction forceps, elevators, and surgical instruments appropriate to the tooth and procedure.
- Expect evidence of checking and preparing the surgical environment, including appropriate lighting, suction, and emergency equipment prior to the procedure.
- Credit the dental nurse for clearly explaining to the patient post-operative care instructions and ensuring they are understood, with specific reference to haemostasis, diet, and oral hygiene.
- Award marks for describing the steps taken to verify the patient’s medical history, ensure valid consent is in place, and communicate any concerns to the clinician.
- Look for evidence of maintaining an aseptic technique throughout the surgical procedure, including correct handling of sterile instruments and swabs.
Assessment Guidance
Guidance for achieving higher grades
- 💡When documenting a tooth extraction, always record the quadrant and tooth notation, reason for extraction, and any complications, as this is frequently examined in record-keeping assessments.
- 💡For OSCE-style stations, demonstrate you have considered the patient’s anxiety and medical status by explaining how you would position the chair, communicate with the patient, and monitor vitals.
- 💡In written answers, explicitly mention 'national guidelines for minor oral surgery' and 'local infection control policies' to show awareness of standards in managing sharps and decontamination.
- 💡If asked about instrument setup, list the full sequence from elevate to extract, including periosteal elevators, luxators, forceps, surgical burs, and suturing materials, and note the use of irrigating solution.
- 💡For the practical exam, always verbalise your actions (e.g., 'I am now checking the patient's medical history') to show the examiner you are following protocols.
- 💡In written exams, use specific terminology from the curriculum, such as 'aseptic technique' instead of 'clean', to demonstrate depth of knowledge.
- 💡When answering case-based questions, link your answer to the GDC's Standards for the Dental Team, especially standard 4 (communication) and standard 7 (maintaining records).
Common Mistakes
Common errors to avoid in your coursework
- Confusing the use of Coupland’s elevators for Warrick James elevators, or selecting inappropriate forceps (e.g., using lower molar forceps on an upper molar).
- Forgetting to check that the patient has signed the consent form and that the medical history has been updated, potentially missing contraindications such as bisphosphonate use.
- Failing to prepare a surgical aspiration tip or not switching from high-volume to surgical suction when required, increasing the risk of surgical site contamination.
- Neglecting to count swabs and instruments before and after surgery, posing a serious patient safety risk.
- Providing the patient with post-extraction instructions verbally only, without written reinforcement or checking understanding, leading to non-compliance and complications.
- Misconception: Dental nurses only clean and sterilise instruments. Correction: They also take X-rays, manage patient records, assist in complex procedures, and provide oral health advice.
- Misconception: The apprenticeship is just work experience with little study. Correction: It involves rigorous academic work, including assignments, exams, and a portfolio of evidence, alongside practical training.
- Misconception: You can work as a dental nurse without GDC registration. Correction: It is illegal to practise as a dental nurse in the UK without being registered with the GDC, which requires passing this diploma or an equivalent.
