   Follow-up: How did you explain your decision to the people affected?

   Follow-up: What early warning signs would alert you that your schedule is becoming unrealistic before your work begins to suffer?

6. You are a first-year dental student preparing a presentation for a public health project with your peers. You find two published reports on the effectiveness of a community oral health initiative that reach opposite conclusions. Your group must brief your tutor tomorrow morning. How would you assess the reliability of these two reports?

   Follow-up: How would you help your group reach a decision if you disagreed about which report was more reliable?

   Follow-up: How would you explain your conclusions to your tutor if both reports carry noticeable weaknesses and the topic remains unresolved?

Communication

1. You are a dental student volunteering at a healthy-eating event hosted by a primary school. A parent named Marcus approaches your oral health information stall because he feels a poster about smoking, diet and oral health shames working parents who are already doing their best. You cannot give clinical advice. Acknowledge Marcus's concerns without being defensive, and discuss the purpose of health promotion respectfully.

   Follow-up: How would you handle it if Marcus shared that he has tried to quit smoking several times without success?

   Follow-up: How could public health posters be designed to encourage positive habits without making people feel judged?

2. You are a dental student working a part-time shift at a local gym front desk. A member named Terry knows you study dentistry and approaches you about a headline on his phone. It claims that routine dental treatment does more harm than good, but he admits he has only read the title. He asks whether you think dentists are misleading the public. You cannot give clinical advice. Explore Terry's concerns and encourage him to read beyond the headline.

   Follow-up: What questions could you suggest Terry ask himself when evaluating health claims on the internet?

   Follow-up: How would you respond if Terry insisted that the headline must be accurate because it went viral?

3. You are a work experience student shadowing at the reception desk of an NHS dental practice. In the staff room, Sam, another student on placement, tells you they feel embarrassed because their hands shook while handing appointment cards to patients. They are worried that staff and patients noticed and want to talk privately. You cannot give clinical advice or guess medical causes. Speak to Sam to offer support and explore sensible ways forward together.

   Follow-up: How would you respond if Sam asked you not to mention their tremor to the practice manager?

   Follow-up: Why is it important to avoid guessing medical reasons when a peer expresses anxiety about physical tremors?

4. You are a sixth-form dentistry applicant helping run a dental careers stall at a secondary school careers fair. A Year 11 student, Maya, approaches you quietly because she does not want to take part in the practical demonstration her teacher organised. You cannot give clinical advice. Speak directly to Maya to acknowledge her preference and reassure her that taking part is entirely voluntary. Do not pressure her to change her mind.

   Follow-up: How could you let the event organiser know with Maya's agreement and without putting her on the spot?

   Follow-up: Why is it important to respect autonomy when someone expresses reluctance to participate in an activity?

5. You are a dentistry applicant volunteering at a residential care home. Your fellow volunteer, Marcus, is upset about a mistake and wants your support. He made a drink with regular sugar for a resident whose dietary plan did not allow it. You noticed and stopped it before it was served. Marcus is worried that he could have caused serious harm. You cannot give clinical advice. Speak directly to Marcus to support him without brushing the mistake aside and agree on how to report it.

   Follow-up: What changes could help prevent a similar mistake in future?

   Follow-up: How would you respond if Marcus asked you to keep the mistake secret?

6. You are a sixth-form dentistry applicant volunteering with a public health charity in a community pharmacy. Your fellow volunteer, Liam, says your explanation of routine dental check-ups to someone in the prescription queue was too technical and left them confused. You cannot give clinical advice. Speak to Liam to respond constructively to his feedback and agree on how to explain the general oral health message more simply.

   Follow-up: How would you handle feedback from Liam that you disagreed with?

   Follow-up: How can you check whether a member of the public has understood your explanation without sounding patronising?

7. You are a dental student volunteering at a youth football club, running a stall about healthy habits and oral health. David, a parent, approaches you because he feels judged by a poster telling families to eliminate sugary snacks and sports drinks. He explains that his family relies on local food parcels and budget multipacks. You cannot give clinical advice. Speak directly to David, listen to his concerns and acknowledge the practical challenges he faces without making him feel criticised.

   Follow-up: How could oral health promotion materials be made more supportive of families who rely on food banks?

   Follow-up: How would you respond if David asked you for clinical advice?

8. You are a dental student volunteering as a student ambassador at the central welcome desk during a busy Cardiff university open day. Jordan, a prospective applicant with a visual impairment, approaches you for directions to the dental building. Jordan is frustrated because several helpers have simply pointed at wall maps. You cannot give clinical advice. Speak directly to Jordan, apologise for the poor communication and ask how they would prefer to receive directions. Do not assume they need physical assistance.

   Follow-up: How would you ask Jordan about their preferred way to navigate the campus without undermining their independence?

   Follow-up: Why is it important to seek consent before offering physical guidance to someone with a sensory impairment?

Ethics

1. You are a first-year dental student observing appointments at a community dental clinic. After a child's appointment, their parent tells you that a member of staff discussed the child's medical history where other patients could hear. The parent asks you to pass their concern to your supervisor. Another staff member suggests keeping quiet because raising it could make a colleague look bad. What would you need to consider, and how would you respond within your role as a student?

   Follow-up: Why is being open about patient concerns important for trust and safety?

   Follow-up: How could you raise this concern with your supervisor while protecting confidentiality and avoiding assumptions about what happened?

2. You are an applicant on work experience at the reception desk of an NHS dental practice. A patient arrives for an emergency appointment for a broken tooth and loudly asks for a different dentist because they do not trust the scheduled dentist's foreign accent. As a work-experience student, how would you respond to the patient?

   Follow-up: If the patient continued making discriminatory remarks, who would you ask for help?

   Follow-up: How could you support the dentist after the incident?

3. You are a first-year dental student on clinical placement at a university dental hospital. You missed a mandatory clinical skills session on basic restorative techniques yesterday because you were unwell. The afternoon clinic starts in ten minutes. Your clinical supervisor asks you to sign the attendance register, calling it a minor formality so you do not have to reschedule the session. How would you respond to your supervisor?

   Follow-up: What risks to patient safety and personal integrity arise if a student signs off on training they did not receive?

   Follow-up: How would you handle the conversation if your supervisor became frustrated and said you were creating unnecessary paperwork for the faculty?

4. You are a dental student observing a consultation with your supervising dentist in a private dental practice. An adult patient is attending a forty-five-minute assessment for extensive cosmetic crowns. Their sibling is present and has offered to pay the full bill. While the sibling steps outside, the patient tells you and the dentist that they do not want the treatment and are only agreeing to please their relative. Preparation work is scheduled to begin in fifteen minutes. The patient asks whether paying gives their sibling the right to decide. How would you respond to the patient's question within your role as a dental student?

   Follow-up: How could you protect the patient's privacy if their sibling asks what was discussed while they were outside?

   Follow-up: What would you discuss with your supervising dentist about the preparation work scheduled to begin in fifteen minutes?

5. You are a first-year dental student in a peer-practice simulation clinic scheduled for two hours. The tutor instructs pairs of students to practise taking dental impressions on one another, but your peer partner has not been told about the material setting time or the gag reflex risks. Your partner looks anxious and tells you quietly that they feel pressured to agree so they do not fall behind in class. How would you address voluntary consent and personal boundaries with your peer and the tutor before starting?

   Follow-up: What essential information should a student receive before consenting to be a practice patient for a classmate?

   Follow-up: How can a student decline to participate as a peer patient without fearing that it will affect their grades or relationship with tutors?

6. You are a first-year dental student assisting in a busy restorative clinic that is running thirty minutes late. Another dental student asks you to countersign a record stating that the cross-infection and equipment safety check was completed. You were cleaning instruments in another bay and did not witness the check. They assure you that the supervising dentist must have done it and urge you to sign so the next patient can enter. How would you respond to the student's request?

   Follow-up: What could be the consequences of signing for a safety check you did not witness?

   Follow-up: How could the clinic team reduce the risk of students facing similar pressure in future?

7. You are a third-year dental student assisting your supervising dentist during a routine filling appointment in an NHS dental practice. The clinic is running fifteen minutes behind schedule. You notice an indicator strip on a pouch containing a reusable dental mirror showing that the autoclave cycle was incomplete. Your supervising dentist is about to pick up the mirror to examine the tooth. What is the safest and most professional action you should take?

   Follow-up: How would you communicate your concern to the dentist calmly in front of the patient?

   Follow-up: What would you do if the dentist suggested using the instrument anyway to save time?

8. You are a sixth-form student undertaking work experience at a dental practice reception. A visitor offers the receptionist an expensive gift card and asks to be moved up the waiting list for an earlier routine booking. Other people waiting nearby overhear the conversation. How should the reception team respond to this offer, and why?

   Follow-up: How might accepting such a gift affect trust among other people waiting for an appointment?

   Follow-up: What would you do as a work experience student if you saw the receptionist accept the gift?

Dental team

1. You are a prospective dental student shadowing the head receptionist and a dental nurse at a busy general dental practice. An adult patient has arrived to have a crown fitted by the associate dentist. Their appointment starts in ten minutes, but the laboratory courier bringing the crown is delayed by at least forty-five minutes. The patient asks you whether their appointment will go ahead on time. How would you respond honestly while staying within your role?

   Follow-up: How could the dental team work together to manage the delay?

   Follow-up: If the patient says they cannot wait because of work commitments, how would you make sure their concerns are passed on to the appropriate team member?

2. You are a fourth-year dental student observing at the reception desk during a placement at a community dental clinic. A patient has been prescribed an antibiotic after an emergency tooth extraction. They ask a newly hired administrative assistant whether it will interact with their regular blood pressure medication. The assistant seems unsure whether they can give advice, and the patient turns to you for help. How would you respond within the limits of your student role?

   Follow-up: How would you help the administrative assistant understand the boundaries of their role?

   Follow-up: What risks could arise if non-clinical team members give advice on prescription medications?

3. You are a school student completing work experience alongside the practice manager at a busy high street dental surgery. An adult patient is at reception trying to book a review appointment after a tooth extraction. The supervising dental surgeon's notes say the patient should be seen in two weeks, but a trainee dentist has verbally told reception to book the visit in six weeks. The waiting area is crowded. The patient turns to you and asks which instruction is correct. As a work-experience student, how would you respond to the patient?

   Follow-up: How would you raise the conflicting instructions with your supervisor while respecting the patient's privacy?

   Follow-up: How could the dental team reduce the risk of conflicting appointment instructions in future?

4. You are a first-year dental student shadowing a multidisciplinary team in a dental clinic. A junior dental nurse notices that an administrative error on an equipment list almost resulted in the wrong tray being brought out, but decides not to mention it because the lead clinician seems rushed and stressed. The nurse privately tells you that they were afraid of being dismissed or reprimanded in front of colleagues. How should a senior colleague respond to help the nurse feel safe to report this near miss?

   Follow-up: How could the team assess whether colleagues feel safe to speak up?

   Follow-up: What simple reporting or debriefing process could help the team capture near misses constructively?

5. You are a second-year dental student observing a team meeting at an NHS dental practice during your primary care placement. The principal dentist is discussing a patient who has severe arthritis in their hands and poor plaque control. The dentist plans to advise daily use of standard manual dental floss. The dental hygienist points out that the patient cannot grip normal floss and suggests considering adapted interdental aids. There are only ten minutes before afternoon appointments begin, and the dentist seems keen to move on. The principal dentist asks you what you think about the hygienist's contribution. How would you respond, recognising the hygienist's expertise and the limits of your role as a student?

   Follow-up: Why is the hygienist's perspective valuable when the team considers this patient's needs?

   Follow-up: If the principal dentist dismissed the hygienist's concern, how could you respectfully raise the importance of listening while staying within your student role?

Public health

1. You are a dental student on placement with an NHS community dental service that wants to improve children's access to appointments. In this fictional practice example, its North and South clinics each booked 100 children's appointments per month from January to April 2026. Staff used booking records to count appointments recorded as missed, as shown in the graph. From March, South began counting appointments cancelled by families within 24 hours as missed, while North continued to count only appointments where the child did not attend without cancelling. The service has a limited budget for appointment reminders and family outreach, and proposes directing most of it towards South because its recorded total rose from 14 in February to 28 in March. Look at the graph below. What would you need to consider before commenting on whether this is a fair way to allocate support?

   Follow-up: What further information would help you distinguish recording differences from barriers that prevent families attending?

   Follow-up: How could the service involve children and parents in designing support without blaming families for missed appointments?

2. You are a sixth-form volunteer helping a community oral health organisation evaluate a local educational outreach programme. A summary report claims the programme was a success solely because attendance rose by thirty percent compared with the previous year. The organisation must decide whether to continue funding the programme or support other initiatives. What further data would you request to assess whether the programme was successful?

   Follow-up: How would you use your findings to help the organisation decide which initiatives to fund?

   Follow-up: How could the team investigate whether the programme reached underserved groups?

3. You are a dentistry applicant volunteering with a local healthcare charity that supports community oral health. The charity is planning a campaign to explain how residents can find local dental services and prepare for appointments. All information will be in English and shared only through the charity’s website and social media accounts. The volunteer coordinator asks you to consider whether this approach will reach the whole community. Who might be excluded, and how could the charity make the campaign more accessible?

   Follow-up: How could the charity involve residents in designing information that meets their needs?

   Follow-up: If the charity had a limited budget, how would you suggest prioritising changes to the campaign?

4. You are a first-year dental student assisting with a university-led public health initiative at a community sports centre. A local charity has funded a one-off weekend workshop to encourage young rugby players to wear mouthguards during their weekly games. The charity wants evidence of lasting value before funding future projects. What long-term outcomes would you measure to evaluate the workshop's impact?

   Follow-up: How would you assess whether the participants continued wearing their mouthguards several months after the workshop ended?

   Follow-up: What comparison or control group could help determine whether changes in habit were genuinely due to the workshop?

5. You are a Year 13 student volunteering to manage your school science club's information stall. A viral social media post claims that an untested home remedy made from household spices can fully replace professional dental check-ups. Visitors ask if they should follow the advice to save money. How would you explain the risks while respecting their concerns?

   Follow-up: What sources and criteria would you use to assess the credibility of the claim?

   Follow-up: How could the science club help visitors assess similar health claims in future?

Dexterity

1. Arrange five small household objects into an asymmetric pattern on a table. Photograph the arrangement, remove the objects and wait 30 seconds. Reconstruct the pattern from memory before looking at the photograph. Compare the positions and orientations with the original, then explain which features you remembered accurately and which you missed.

   Follow-up: Which reference points helped you remember the arrangement?

   Follow-up: How would you change your observation method on a second attempt?

2. Place twelve dried pasta pieces on a tray and draw twelve circles on a sheet of paper, each wider than a pasta piece. Using blunt-ended tweezers, transfer one piece into each circle without placing it across the boundary. Work for up to three minutes, then count misplaced or dropped pieces and explain how you controlled your movements. Keep small items away from young children and pets.

   Follow-up: How did the position of the tray and paper affect your control?

   Follow-up: What would you change if accuracy declined as you reached the final circles?

3. You and a partner each have a square sheet of paper. Give spoken instructions for folding it corner to corner into a triangle, then folding that triangle in half again. Your partner must follow your words without watching your hands. If alone, record the instructions and follow them later on a fresh sheet.

   Follow-up: What does comparing the finished shapes tell you about how clearly you explained the starting orientation and fold directions?

   Follow-up: How would you clarify a folding mistake using words alone?

4. Tell us about a practical task from a hobby, study or employment that did not go as planned. How did you decide whether to repair your work or begin again?

   Follow-up: How did you check whether your decision improved the result?

   Follow-up: How would you approach the same task differently next time?

Teamwork

1. You are a sixth-form volunteer organising a community food drive with three other students. At your last planning meeting, one dominant team member took everyone's silence as agreement to a demanding schedule. You later learn that a quieter teammate feels uncomfortable and overwhelmed by the decision. The event is a week away, morale is dropping and key tasks may be missed. How would you help the team agree on a manageable plan?

   Follow-up: How would you invite the quieter team member to share their thoughts during meetings without putting them on the spot?

   Follow-up: What would you do if the more vocal teammate dismissed the quieter member's concerns when they were raised?

2. You are a first-year dental student working with four peers on an assessed health promotion poster due next week. The group is falling behind because one member has taken on extra caring responsibilities for a sick relative. They have told you this in confidence. How would you help the group share the remaining work fairly?

   Follow-up: How would you explain the need to redistribute tasks while protecting your teammate's privacy?

   Follow-up: How would you respond if another group member complained that the new workload distribution was unfair?

3. You are a Year 13 student who recently completed a joint biology presentation with three classmates. Following the presentation, your teacher publicly praises the whole group for an outstanding piece of work and awards top marks. In reality, one student completed almost the entire slide deck and research alone because the others failed to meet their internal deadlines. How would you handle this situation to ensure credit is shared honestly without causing unnecessary conflict?

   Follow-up: How would you speak to the classmate who carried the workload to understand how they feel about the situation?

   Follow-up: What would you say to the teacher if the group agreed that the feedback did not accurately reflect individual contributions?

4. You are a sixth-form student volunteering with a team of five peers running an outdoor community sports day. Heavy rain makes the grass pitch unsafe, forcing the event to move immediately into a small indoor hall. Several team members are panicking, and visitors are unsure where to go. How would you help your team stay calm and reorganise for the move indoors?

   Follow-up: How would you decide which activities to prioritise and which to cancel when space is limited indoors?

   Follow-up: How would you communicate the changes clearly to visitors and fellow volunteers?

5. You are a first-year dental student preparing a hands-on laboratory demonstration with three peers for incoming students. While rehearsing, two members of your group strongly disagree about the safest order of steps to follow when handling the equipment, and the discussion is becoming heated. The demonstration is due to start in under an hour. How would you help the group resolve this disagreement?

   Follow-up: How would you determine which steps are safety-critical?

   Follow-up: Who would you turn to for authoritative advice if your group could not reach an agreement in time?

Reasoning

1. You are a prospective dental student at an interview station. A local community survey concludes that dental access across the county is excellent, based solely on questionnaires completed by people attending routine appointments at high street practices. You have been asked to review the findings before they are submitted to a regional healthcare committee. How reliable is this conclusion, and why?

   Follow-up: What additional information would you need before accepting the conclusion?

   Follow-up: What practical methods could be used to gather feedback from people who have struggled to access dental services?

2. You are a first-year dental student observing the practice manager at a community dental clinic that provides special care dentistry. In this invented practice dataset, the clinic scheduled 200 routine check-ups in each month from April to June. Its booking system recorded 20 appointments as missed in April, 30 in May and 30 in June. From June, the system counted same-day cancellations as missed appointments, whereas previously it counted only patients who did not attend without cancelling. A dental nurse suggests that patients forget appointments, while a receptionist suggests that public transport costs and inflexible shift work prevent attendance. Concerned about unused NHS appointment time, the practice manager asks you to suggest a fair investigation to run during July. Look at the graph below. How would you investigate these explanations without placing unfair blame on patients, and what would you consider before interpreting the recorded rates?

   Follow-up: What information could the clinic collect to explore forgetting, transport costs and working hours fairly?

   Follow-up: Why should the clinic consider barriers to attendance before introducing penalties for missed appointments?

3. You are an applicant on a hospital work experience placement, shadowing a dental public health analyst at a regional health authority in Wales. The analyst shows you invented practice data on monthly emergency dental walk-in visits from January to June 2025. Recorded visits fell from 1,000 in January to 600 in June. In February, the authority introduced an online booking app and permanently closed two of its three community dental clinics due to funding cuts. The figures count completed walk-in visits across all three clinics in January but only the remaining central clinic from February onwards, and exclude appointments booked through the app. The authority's board meets tomorrow and wants to claim that the app alone solved the emergency care problem. Look at the graph below. What conclusions can and cannot be drawn from these data?

   Follow-up: What other information or comparison data would you need before concluding that the app actually reduced patient emergencies?

   Follow-up: What might have happened to the patients who would previously have visited the two clinics that were closed down?
