OSCE Practice – Dietary Advice for High Sugar Intake
Practise patient communication and oral health education aligned with NEBDN OSCE expectations.
Scenario
You are a dental nurse working in a general dental practice.
During a routine dental examination, the dentist identifies early signs of dental decay and asks you to reinforce dietary advice.
The patient says:
“I know sugary drinks aren’t great, but I drink them every day because they help me stay awake.”
You are supporting the clinician and providing oral health advice.
Your Task
In this OSCE scenario, you are expected to provide supportive, realistic, and professional dietary advice to help improve oral health.
You should be able to:
- Explain the oral health risks linked to frequent sugar intake
- Reinforce appropriate dietary advice
- Discuss healthier drink alternatives
- Encourage realistic behaviour change
- Communicate professionally and without judgement
- Check the patient understands the advice provided

This Scenario Assesses
This station tests important NEBDN oral health education and communication skills, including:

This scenario also develops confidence in discussing sensitive lifestyle habits while supporting patients to make realistic improvements.
Model Answer / Ideal Response
A strong response should be supportive, realistic, and focused on small achievable improvements.
Step 1 — Acknowledge the Patient’s Situation
Start professionally and without judgement.
Example:
“I understand. Let’s talk about some simple ways to reduce the effect sugary drinks can have on your teeth.”
This keeps the conversation supportive and encourages engagement.
Step 2 — Explain the Oral Health Risk
Explain simply that:
- Frequent sugary drinks increase the risk of tooth decay
- Sugar feeds bacteria that produce acid
- Repeated exposure throughout the day increases risk
Avoid overly technical language.
Example:
“It is often how frequently sugary drinks are consumed that increases the risk of decay.”
Step 3 — Provide Practical Dietary Advice
Advise the patient to:
- Reduce sugary drinks where possible
- Avoid frequent sipping throughout the day
- Choose water or sugar-free alternatives when possible
- Keep sugary drinks to mealtimes where appropriate
Advice should feel realistic and achievable.
Step 4 — Encourage Gradual Change
Avoid unrealistic expectations.
Example:
“You do not have to stop everything immediately. Even small changes can make a big difference over time.”
This supports positive behaviour change.
Step 5 — Check Understanding
Before ending the conversation:
- Ask if the patient has questions
- Confirm understanding
Example:
“Does that make sense, or is there anything you would like me to explain again?”
Common Mistakes to Avoid
- Sounding judgemental or blaming the patient
- Telling the patient to stop sugary drinks immediately without support
- Forgetting to explain sugar frequency
- Giving unrealistic advice
- Using overly complicated language
- Ending the interaction without checking understanding
Key Learning Points
- Frequent sugar intake increases the risk of dental decay
- Sugar frequency is often more important than quantity alone
- Water and sugar-free alternatives are generally better options
- Behaviour change should be realistic and supportive
- Communication should remain professional and non-judgemental
