Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

Course Description

This unit deals with the knowledge and skills required to polish restorations for the elimination of plaque retentive factors and to remove overhanging margins for the promotion of optimum oral health.

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 appropriate
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 accordingly

Assessment Tasks

Assessment for this course forms part of the Advanced Diploma of Oral Health (Dental Hygiene).
Training is mapped to the Australian Dental Council June 2011 “Professional attributes and competencies of the newly qualified dental hygienist” and the Dental Board of Australia “Scope of Practice”.
Students must abide by the 2012 “ADA Guidelines for Infection Control Second Edition”, 2010 NHMRC “Australian Guidelines for the Prevention and Control of Infection in Healthcare” and Worksafe Victoria “Occupational Health and Safety Regulations 2007”.
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. Please refer to definition of Vocational Competency (;ID=xjog855ryrtq;STATUS=A;SECTION=3;PAGE_AUTHOR=Penny%20Mercer).
Assessment is undertaken through successful completion of all assessment activities and classroom, project & industry participation. Assessment will also be undertaken replicating workplace conditions (as far as possible), and where relevant undertaken in the clinical setting. 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.
The RMIT assessment policy outlines your responsibilities as a RMIT student as well as those of your teachers ( (unresolved)).

Assessment Matrix

All summative assessments listed are compulsory for a successful outcome.
