Key Points
-
This paper evaluates a head mounted camera for use in clinical teaching.
-
The device improved the level of detail observed during dental procedures, and the level of feedback to learners.
-
It also provided better learner support by both enabling the learner to observe a dental procedure being undertaken from the viewpoint of the operator and permitting the teacher to view a learner undertaking a procedure.
Abstract
Objective To evaluate the potential of a novel head mounted camera to both improve the level of detail observed by learners/teachers observing dental procedures being undertaken and to improve the level of feedback given to learners.
Design Questionnaire.
Subjects and methods Qualified members of the dental team and those in training evaluated the usefulness of the application of a novel head mounted camera in their clinical teaching within Dundee Dental School and Hospital.
Results A total of 210 questionnaires were issued and received for analysis. Although the device generally improved the level of detail observed by learners/teachers and improved the level of feedback given to learners, there was scope for improving upon image quality. The lighting of the environment in which the camera was used was a critical factor in optimising success. The different members of the dental team displayed different expectations of the device. This was attributed in part to their level of previous exposure to clinical work. In applying this technology it is therefore important to understand the needs of the user.
Conclusions The camera system did enhance the learning experience but required further refinement in relation to image quality.

This evaluation was funded by a miniproject grant awarded by the Learning and Teaching Support Network (LTSN 01 – Mini Project 24). The work reported here would not have reached fruition without the support of the engineering students Marco Steinberg and Jan Hoppner of the Technische University of Ilmenau, Germany who built and maintained the head mounted camera system. We are also grateful to Mr Mark Tulley (retired Principal Medical Physicist) for camera development and also to Professor W. P. Saunders, Dean of Dentistry, for funding in part the cameras development. Finally we thank all staff and students who participated in the evaluation.
