This unit describes the skills and knowledge required to perform dental prophylaxis and assist with simple extractions. Dental prophylaxis involves oral examinations of the conscious and anaesthetised patient, sub- and supra-gingival tooth scaling and polishing, and the subsequent development of a homecare plan, as well as assisting in the performance of simple dental extractions.Veterinary dental nursing procedures are most often carried out on dogs and cats.The unit applies to veterinary nurses who work independently, under the supervision of a registered veterinarian in a veterinary practice. Veterinary nurses who carry out dental nursing procedures need to hold and apply specialised knowledge of anatomy of the animal oral cavity, including teeth, bone and gums.Legislative and regulatory requirements apply to veterinary nurses but vary according to state/territory jurisdictions. Users must check with the relevant regulatory authority before delivery.NOTE: The terms 'occupational health and safety' (OHS) and 'work health and safety' (WHS) generally have the same meaning in the workplace. In jurisdictions where the national model WHS legislation has not been implemented, RTOs must contextualise the unit of competency by referring to current OHS legislative requirements.
