National Codes, Titles, Elements and Performance Criteria

National Element Code & Title:

TAFEDH021 Polish restorations and remove overhanging margins


1. Preparation and presentation of surgery

Performance Criteria:

1.1 Prepare, gather and place all equipment, materials and
instruments required for the patient’s treatment
(including for any procedure(s) to be undertaken in
addition to polishing and overhang removal) within the
treatment cubicle
1.2 Prepare the surgery to cater for any predetermined
special needs of the patient as determined from the case notes and/or patient’s immediate needs 1.3 Prepare equipment and instruments are and select
according to relevant guidelines and manufacturer’s
recommendations to ensure compatibility with the
different types of restorative materials used in dentistry
and according to the size, location and type of
restorative material to be polished, or overhanging
margin to be removed
1.4 Set up and maintain equipment, instruments and
medicaments according to relevant guidelines for
instrument care and maintenance
1.5 Follow all necessary safety precautions during the
preparation and presentation stages


2. Prepare and assess the patient

Performance Criteria:

2.1 Patient’s medical history and records are reviewed to
eliminate any contraindications to proposed treatment
modalities and to confirm treatment prescriptions
2.2 Patient’s treatment plan and records are reviewed to
determine and confirm restorations requiring polishing
and overhanging margin removal to review the degree
of treatment required
2.3 An explanation of the polishing and overhang removal
process and the possible sensations produced by any
instrument or equipment used is given to the patient.
Adhering to the principles of informed consent, the
patient is informed of possible negative outcomes
resulting from any planned treatment. Consent is
confirmed with the patient allowing the opportunity to
ask questions
2.4 Socially inclusive communication skills are used at all
times and demonstrated behaviours encourage a
supportive treatment environment that is conducive to a
collaborative operator/patient relationship
2.5 The restorations to be polished and overhanging
margins to be removed are thoroughly examined to
confirm treatment prescription
2.6 The need for pain control is determined through
discussion with the patient and liaison with the
supervising dentist and any necessary requirements are
followed through


3. Polish restorations and remove/smooth overhanging/rough margins

Performance Criteria:

3.1 All proposed treatment is carried out according to
occupational health, safety and welfare guidelines and
Infection control policy and procedures and current
evidenced based practice
3.2 Prior to intervention, the restoration(s) and adjacent
teeth are examined consulting dental radiographs and via tactile exploration using a dental explorer and floss
to determine objectives and identify associated risks
3.3 Consider and implement pain control as required
3.4 Prepared equipment is used to smooth and remove
excess and rough restorative material to support oral
health objectives
3.5 All possible efforts are made to reduce any heat
production, and the use of irrigation is employed where
3.6 Review the restoration periodically to detect the early
achievement of the desired outcome and consequently
minimising the amount of restoration removal and
possible tissue trauma
3.7 Apply knowledge of tooth morphology, restoration
contours and soft tissue proximity to avoid excess
removal and trauma
3.8 Maintain ergonomic practice to support operator and
patient comfort and access
3.9 Review the final outcome, evaluate and modify

Assessment Tasks

Assessment for this course forms part of the Advanced Diploma of Oral Health (Dental hygiene)
Refer to the Australian Dental Council June 2011 document “Professional attributes and competencies of the newly qualified dental hygienist for additional information”
Primary assessment involves on-going practical and applied assessment in a clinical workplace or simulated environment such as a supervised student clinic.
Assessment is typically based around written and/or online tests, assignments, reflective journals, evidence portfolio’s, logbooks and/or practical demonstrations.
Competency based training requires the student to be in attendance in order for assessment to be undertaken.
Assessment is undertaken through successful completion of all assessment activities and classroom, project & industry participation.
Assessments are spaced across the duration of the course, in order for your teacher to provide you with progressive feedback.
Feedback will be provided throughout the semester in class and/or online discussions, through individual and group feedback on practical exercises and by individual consultation.
If you have a long term medical condition and/or disability it may be possible to negotiate to vary aspects of the learning or assessment methods. You can contact the program coordinator or the Disability Liaison Unit if you would like to find out more.
An RMIT assessment charter ( ) summarises your responsibilities as an RMIT student as well as those of your teachers.
Your course assessment conforms to RMIT assessment principles, regulations, policies and procedures which are described and referenced in a single document, the Assessment policies and procedures manual (;ID=ln1kd66y87rc).
