MJDF Part 1 - Membership of Joint Dental Faculties Patient Assessment and Diagnosis Questions and Answers — Questions and Answers
Question 1: A 68-year-old male patient attends for a routine examination. His medical history reveals a prosthetic heart valve replacement 3 years ago. He is scheduled for a dental extraction. According to the Scottish Dental Clinical Effectiveness Programme (SDCEP) guidance, which is based on NICE Clinical Guideline 64, what is the most appropriate course of action regarding antibiotic prophylaxis?
- Administer 2g amoxicillin orally one hour before the procedure.
- Antibiotic prophylaxis is not routinely recommended for this patient. (Correct answer)
- Consult the patient's GP to decide on the antibiotic regimen.
- Prescribe a 5-day course of metronidazole to begin on the day of the extraction.
Correct answer: Antibiotic prophylaxis is not routinely recommended for this patient.
Current UK guidelines, specifically NICE guideline CG64 and the implementation advice from SDCEP, state that antibiotic prophylaxis against infective endocarditis is not routinely recommended for people undergoing dental procedures. While patients with prosthetic valves are at a higher risk of infective endocarditis, the guidance moved away from routine prophylaxis due to the lack of evidence of its effectiveness and the risks of antibiotic resistance. The decision to provide prophylaxis should be made on a non-routine, individual basis after consultation between the patient, their dentist, and their cardiology team.
Question 2: According to the Ionising Radiation (Medical Exposure) Regulations 2017 (IR(ME)R), who holds the primary legal responsibility for the justification of an individual medical exposure, such as a dental radiograph?
- The Radiographer or Dental Nurse who operates the X-ray machine.
- The Referrer who requested the imaging examination.
- The IR(ME)R Practitioner. (Correct answer)
- The Medical Physics Expert (MPE).
Correct answer: The IR(ME)R Practitioner.
IR(ME)R 2017 clearly defines the roles and responsibilities related to medical exposures. The 'Practitioner' is a registered healthcare professional who is entitled by the employer to take responsibility for the justification of an individual medical exposure. The referrer provides medical data, and the operator performs the practical aspects, but the ultimate legal responsibility for justifying that the benefits of the exposure outweigh the risks for that specific patient lies with the Practitioner.
Question 3: A 25-year-old patient who is a regular attender and has demonstrated excellent oral hygiene with no new caries or periodontal issues for the last 4 years attends for their check-up. According to NICE guideline [CG19] on dental recall intervals, what is the maximum recommended interval before their next oral health review?
- 6 months
- 12 months
- 18 months
- 24 months (Correct answer)
Correct answer: 24 months
NICE guideline [CG19] recommends a risk-based approach to recall intervals. For an adult patient (aged 18 and over) who has repeatedly demonstrated they can maintain oral health and is not considered to be at risk, the recall interval may be extended over time up to a maximum of 24 months. Intervals longer than this are considered undesirable as they may diminish the professional relationship between dentist and patient.
Question 4: A dentist is carrying out an assessment of a new patient. Which of the following is considered a fundamental requirement of good record-keeping as outlined by the General Dental Council (GDC) and guidance from bodies like the FGDP(UK)?
- Recording the patient's occupation and hobbies in detail.
- Ensuring the notes are countersigned by a dental nurse.
- Making and keeping accurate and contemporaneous patient records. (Correct answer)
- Using a standardised digital template for all entries without exception.
Correct answer: Making and keeping accurate and contemporaneous patient records.
The General Dental Council's 'Standards for the Dental Team' mandates that dental professionals must make and keep accurate, complete, legible, and contemporaneous patient records. This is a core professional duty. While details like occupation can be relevant, they are not a fundamental requirement for all records. Countersigning is not a universal GDC requirement, and while templates are useful, their use must be appropriate and not compromise the accuracy of the record for the individual patient.
Question 5: During a new patient examination, a 45-year-old man mentions he has been experiencing persistent hoarseness for the last 4 weeks, along with a feeling of a lump in his throat. He is a heavy smoker. What is the most appropriate immediate action?
- Reassure the patient that it is likely a minor throat infection and review in 3 months.
- Prescribe a course of broad-spectrum antibiotics.
- Advise the patient to buy over-the-counter throat lozenges and monitor symptoms.
- Make an urgent referral under the 'two-week wait' pathway for suspected head and neck cancer. (Correct answer)
Correct answer: Make an urgent referral under the 'two-week wait' pathway for suspected head and neck cancer.
According to NICE guideline [NG12] on suspected cancer, persistent hoarseness in a person aged 45 and over is a key symptom that warrants an urgent 'two-week wait' referral to a head and neck specialist to rule out laryngeal cancer. The patient's smoking history further increases the risk. Reassurance, antibiotics, or simple monitoring would be inappropriate and could delay a potentially serious diagnosis.
Question 6: Which of the nine principles outlined in the GDC's 'Standards for the Dental Team' is most directly addressed when a dentist explains the risks, benefits, and costs of different treatment options to a patient before they agree to proceed?
- Principle 1: Put patients' interests first.
- Principle 4: Maintain and protect patients' information.
- Principle 3: Obtain valid consent. (Correct answer)
- Principle 8: Raise concerns if patients are at risk.
Correct answer: Principle 3: Obtain valid consent.
GDC Standard 3, 'Obtain valid consent', requires that consent is obtained before every examination and treatment. For consent to be valid, it must be informed. This involves giving the patient all the relevant information, including the risks, benefits, alternatives, and costs of the proposed treatment, in a way they can understand. While putting the patient's interests first (Principle 1) is the overarching goal, the specific act of providing comprehensive information to allow the patient to make a choice relates directly to obtaining valid, informed consent.
