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
