Introduction: In an ageing society, the frequency of medical emergencies in a dental setting appears to be increasing because of a growing number of medically compromised patients. However, we currently have no dental‐specific simulation environment with advanced reproducibility for medical emergencies. Therefore, we used the robot patient in objective structured clinical examinations (OSCEs) for testing student competence in emergency management. This study aimed to evaluate student responses to medical emergencies in the dental setting.Material and Methods: We used 98 fifth‐grade dental students at Showa University as subjects and implemented the OSCE task entitled ‘Management of medical emergency using a robot patient’. Candidates were asked to manage an emergency situation immediately after local anaesthesia, with one robot patient configured to develop vasovagal syncope and the other to experience adrenaline hypersensitivity. A questionnaire on the educational value of the robot patient was completed after the examination.Results: Thirty‐two per cent of students could not accurately count her pulse because of an inappropriate method. Moreover, 78% could not correctly attach either the tonometer or pulse oximetry to the patient. Accurate diagnoses were given by only 22% of students, with vasovagal syncope diagnosed by 33% and adrenaline hypersensitivity by 8%. From a questionnaire, 78% of students recognised the usefulness of the robot patient in medical emergency training.Conclusion: We found that student responses to the emergency situation were poor. The robot patient is useful in dental education for medical emergency training and assessment not only for situation management but also for differential diagnosis.

In recent years, with the increasing social awareness of safety in medical practice, improving clinical skills has become very important, especially for recently graduated dentists. Traditionally, mannequins have been used for clinical skill training, but a mannequin is quite different from a real patient because they have no autonomous movement or conversational ability. This indicates that pre‐clinical simulation education is inadequate. We have, therefore, developed a robot patient that can reproduce an authentic clinical situation for dental clinical training. The robot patient, designed as a full‐body model with a height of 157 cm, has eight degrees of freedom in the head and the ability to perform various autonomous movements. Moreover, saliva secretion and conversation with the trainee can be reproduced. We have introduced the robot patient into an objective structured clinical examination targeted at fifth‐grade students in our dental school to evaluate their skills in cavity preparation, whilst considering the safety of the treatment. As a result, many of the students were able to deal appropriately with a patient’s unexpected movement. Moreover, results of a questionnaire survey showed that almost all the students recognised the educational value of the robot patient especially for ‘risk management’, and they preferred the robot patient to traditional mannequins. Practical application of the robot patient in dental clinical education was evaluated through the experiences of the fifth‐grade students, which showed the effectiveness of the robot patient in the dental field.
