CORE CURRICULUM IN DENTAL

RADIOGRAPHY AND RADIOLOGY FOR

UNDERGRADUATE DENTAL STUDENTS

INTRODUCTION

A core curriculum in Dental Radiography and Radiology for undergraduate dental students was approved by the Council of the British Society of Dental and Maxillofacial Radiology (BSDMFR) in October 1993. It received wide circulation following circulation as Appendix C of Guidelines for Radiology Standards for Primary Dental Care^1.

Regulation 11 paragraph 1 of The Ionising Radiation (Medical Exposure) Regulations 2000 (IRMER)^2 states that no practitioner or operator shall carry out a medical (or dental) exposure or any practical aspect without having been adequately trained. The requirements for adequate training are set out in Schedule 2 of the Regulations. The Schedule states that practitioners and operators shall have completed training, including theoretical knowledge and practical experience in i) Radiation production, radiation protection and statutory obligations relating to ionising radiations, as are relevant to their functions as practitioner or operator; and ii) Diagnostic radiology as relevant to their specific area of practice.

The core curriculum is intended to meet the requirement for adequate training in those subjects specified in Schedule 2 of IR(ME)R 2000, which are indicated by an asterisk (*) in the text that follows. Implementation of this core curriculum into the undergraduate dental course will also fulfil the requirements of the second edition of the First Five Years^3.

It is 6 years since the first revision of the ‘Core Curriculum’, and it was felt by BSDMFR council at the April 2008 meeting that there had been sufficient developments to warrant further revision.

*Responsibility for radiation safety *Routine inspection and testing of equipment *Notification of faults and Health Department hazard warnings *Clinical audit

Apparatus and equipment Basic circuitry of stationary anode, self-rectified and direct current x-ray sets X-ray tube - cathode, anode, focal spot size and vacuum Heat production and how it is dispersed Basic components of the dental x-ray set Timers Applied potential (kV), tube current (mA) and exposure setting (mAs) - how change affects x-ray quality and quantity

Films and processing Film types - direct action and indirect action/screen film Intensifying screens Black and white final image production - effect of exposure Emphasis on processing - chemistry, wet and automatic processing and film faults Darkroom - design and safelights

Digital imaging Principles of digital image production Intra-oral and extra-oral systems using:

• Solid state detectors
• Photostimulable phosphor plates Digital image faults and Quality Assurance Data storage and retrieval, and data protection

Radiographic techniques of which an appropriate level of theoretical knowledge is required Skull views, tomography and contrast radiology, eg sialography, arthrography and angiography Other modalities, eg Cone Beam CT, conventional CT, MRI, ultrasound and radionuclide scanning

PRACTICAL INSTRUCTION

Practical instruction in this curriculum should be undertaken by students to obtain experience in the radiographic techniques carried out with x-ray equipment normally available to dental practitioners, to a level such that they are able to comply with current legislation.

Principles of imaging Geometric requirements for image production Importance of quality of image - effects of distortion Use and limitation of radiography as a diagnostic aid

Film handling Storage - protection from heat, damp and radiation *Conventional film processing Film fault identification Filing and retrieval Information exchange

Digital Imaging Care of digital imaging receptors Identification of digital image faults Image storage and data protection

Techniques Students should know the *fundamentals of radiological techniques used in dentistry and be able to select and use the correct equipment

Intra-oral techniques (using conventional and digital systems) Bitewings Periapical views - paralleling technique and bisected angle technique Image receptor holders and secondary collimation Endodontic radiography Occlusal radiography

Metabolic disorders of significance in dental practice Trauma including fractures - teeth

• facial bones Disorders of the temporomandibular joints Disorders of the salivary glands Disorders of the paranasal sinuses

Time required This course could be covered using lectures, practical radiography and seminars. Other teaching styles may also be used such as computer-aided and problem-based learning. The main objective of the course is that upon graduating students should be competent to undertake dental radiography and radiology to a level and standard required for general practice. It is suggested that a total of 80 hours is normally sufficient to cover the course but this is not prescriptive since the number of hours taught is not as important as the quality of the teaching received^5.

Examination It is considered essential that this curriculum is formally assessed within the examination structure of the individual dental schools, and that each major area is identifiable. This will ensure that the dental degree certificate is evidence of ‘adequate training’ as required under IR(ME)R 2000^2.

Tuition The implementation of this course is dependent on the appointment to the staff of each dental school/hospital of an adequate number of properly trained dental radiologists, at least one of whom should be a specialist^3 and preferably a consultant in view of the service commitments.
