Dental and Maxillofacial Radiology

• Dental Specialty

• Specialise in radiology of teeth, jaws and adjacent structures

Dental Radiology in the UK : 11 million / year

Radiology in Dental Curriculum

• 3rd year BDS

• Radiation physics, radiation protection, radiography, radiological anatomy

• Examination – must be passed

Previous exam format

• Written paper of 2 hours duration

• Mixture of T/F and short answer style questions

Concerns with paper exams

• Lack of consistency in marking

• Feedback from candidates

• Inability to include actual radiographs

• The task of marking

October 2006

• Attended a study day organised by the University of Dundee focused on Education

• Presentation by Dr David Walker on e-learning and assessment

• Started a discussion about piloting online version of examination

Disadvantages of electronic format

• Considerable amount of work to set up

• No “free text”

• Some questions are difficult to transfer to this format

Colleague concerns

• Is it easier? – “answer in front of candidate”

• Exam shorter (1 hour on computer; 2 hours on paper)

• Is understanding being assessed?

Radiological anatomy and quality assessments – can use real images not line diagrams

Drag and Drop not previously possible

This is a periapical radiograph of maxillary molars and premolars.From the selection of words below, drag and drop the correct label to identify the radiographic feature:

EnamelCaries DentineZygomaPulp

Nasal cavity Maxillary sinusCalculus

Drawing questions more difficult to adapt

Ways around inability to draw

In this question, the blue line represents dental radiographic film and the yellow lines the incident X-ray beam.

Select the diagram which demonstrates the relationship of the tooth, beam and film for bisecting angle periapical radiograph.

What’s happening now?

• First exam was in February 2009 • Examination + resit every year (100 students / year)• Continuous evolution – try and write some new

questions for each semester• Used elsewhere

– University of the Highlands and Islands– University of Aberdeen

Advantages of computer exams

• Speed of results & reduced time to mark

• Giving feedback easier

• Students happier (via interviewing students)

• Colleagues happy

POSSIBLE FUTURE USE OF OBSERVATIONAL ASSESSMENTS

Observational assessment vs. ‘traditional’ quiz, test or exam

Typical workflow for “observer”

Observational assessments

• Benefits of doing on-screen vs paper– Saves time and money as no need to scan/transcribe– Results online instantly– Computer manages workflow– Participant gets feedback online– No illegible handwriting!

Can we computerize dental OSCEs?

• Existing paper-based OSCE form at Dundee Dental School

• Inexpensive, very portable Internet-connected mobile devices are often ideal for delivering online observational assessments

Mobile devices

The same assessment that is delivered on traditional laptop can be delivered via a handheld mobile device such as iPad, iPhone or Android phone/tablet
