Course Description

This unit of competency describes the skills and knowledge required to minimise the risk of radiation to the client, the operator and others during the exposure of a prescribed dental radiographic image.  It also describes the quality assurance measures necessary to ensure all radiographs are of consistent diagnostic standard

All procedures are carried out in accordance with work health and safety (WHS) policies and procedures, current infection control guidelines, Australian and New Zealand Standards for  maintaining infection control and the policies and procedures of the dental practice or organisation.  All tasks are carried out in accordance with
State/Territory legislative requirements.

This unit applies to dental assistants who assist at the chairside

This unit of competency is delivered against current industry standards. It is recommended that all students are familiar with the current ADA Infection Control Guidelines Document 2012 or the most current version of this document.

Students are required to support the learning outcomes for Unit HLTDA410D Apply the principles of radiation biology and protection in dental practicewith work based experience and further self-managed research to support positive outcomes in this Unit.

 
To undertake a practical clinical assessment (simulation), students MUST present for the assessment process as follows:

• Appropriate clinical attire (no jeans or tracksuit pants, no bare midriff, no singlet tops).
• Footwear fully covered in leather/vinyl (not suede) clinical footwear.
Hair is to be contained by tying back or in appropriate hair cover.

• No jewellery to be worn on the hands or wrists. Wedding rings or jewellery that cannot be removed for
cultural reasons must be taped with an appropriate waterproof tape.
• All cuts/ skin abrasions on the hands or wrists must be covered with a waterproof dressing

You will attempt the practical assessments under supervision of the teacher and you will be graded with either a S (Satisfactory) or NYS (Not Yet Satisfactory).

The summative assessments for HLTDA410D are:

Written Report Radiographic equipment and Safety, Submitted online via Blackboard
This is a written report of the student’s dental radiographic equipment in their workplace.

Simulated practical assessment.
This is a simulated assessment in the Level 3 Sim Lab involving all 3 technique- Bisecting, Paralleling and Bitewing. After successful completion of this assessment students will be permitted to take radiographs on real patients under direct supervision of their workplace mentors.

Patient portfolio of 30 films
Upon commencement on the real patients, students are required to submit 10 films each time (x3) when attending RMIT for classes.

Log Book
The student submits the completed LogBook of dental radiographs completed in their workplace.

Written Assessment
As per Certificate IV in Dental Assisting Timetable, which is issued on Induction Day and located on BlackBoard. Assessment will be based on all topics delivered throughout the course (including Radiation principles, Dental Anatomy, Legal and Ethical, Errors, Oral Pathology, Techniques etc). The written test is a combination of multiple choice, true and false and short answer questions. A final pass mark of 60 % is required for a pass in HLTDA407D Produce a dental radiographic image.

Workplace Assessment
This is a Workplace Assessment in the student’s workplace involving all 3 technique- Bisecting, Paralleling and Bitewing. The student must show competency across all elements for the three dental radiographic units for the simulated and workplace assessment.

Failure to complete any of the above listed tasks/assessments will result in an NYC (Not yet competent) for the unit HLTDA410D Apply the principles of radiation biology and protection in dental practice. A NYC result will be entered in the student record. This will result in non-completion of this unit of competency and re-enrolment will be required incurring fees and a return to class work and completion of the relevant assessments at the time of the re-enrolment.

(The assessments process must be finalised and a result entered by the end of the RMIT enrolment for the unit HLTDA410D Apply the principles of radiation biology and protection in dental practice).
