MJDF Part 1 - Membership of Joint Dental Faculties Patient Assessment and Diagnosis 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?

Accepted Answer

Antibiotic prophylaxis is not routinely recommended for this patient.

Answer

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?

Accepted Answer

The IR(ME)R Practitioner.

Answer

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?

Accepted Answer

24 months

Answer

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)?

Accepted Answer

Making and keeping accurate and contemporaneous patient records.

Answer

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?

Accepted Answer

Make an urgent referral under the 'two-week wait' pathway for suspected head and neck cancer.

Answer

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.
