Regulation 20

a dentist who has been issued a certification that certifies the individual’s competency in the conduct of dental cone beam computed tomography by a body specified by the Director‑General; (b)a medical practitioner who is registered under section 22 of the Medical Registration Act 1997 as a specialist in the branch of diagnostic radiology; (c)an oral health therapist; or (d)a radiographer who is a duly qualified allied health professional.

ensure that any dental cone beam computed tomography is conducted on a patient after the following conditions have been satisfied:

a dentist has assessed that the use of dental x‑ray, which emits a lower dose of radiation than dental cone beam computed tomography, would not be capable of producing an accurate image of the patient’s dental structures;

a dentist, having reviewed the patient’s medical history and conducted a clinical examination on the patient, has assessed that the potential benefits of conducting dental cone beam computed tomography on the patient outweigh the potential risks to the patient;

if the proposed dental cone beam computed tomography is the second or subsequent dental cone beam computed tomography to be conducted on the patient, a qualified person has considered whether the procedure may be conducted on a part of the patient’s teeth, jaws or associated structures that is different from, or is a smaller portion of, the part of the patient’s teeth, jaws or associated structures that were previously subject to dental cone beam computed tomography, to minimise the exposure of any particular area of the patient’s teeth, jaws or associated structures to radiation;

keep and maintain proper and accurate records of the conditions mentioned in sub‑paragraph (a)(i), (ii) and (iii) being satisfied in respect of every dental cone beam computed tomography conducted on a patient; and

ensure that the field of view for each dental cone beam computed tomography is collimated to the area of clinical interest.

a dentist who has been issued a certification that certifies the individual’s competency in the reading of dental cone beam computed tomography images by a body specified by the Director‑General; or

a medical practitioner who is registered under section 22 of the Medical Registration Act 1997 as a specialist in the branch of diagnostic radiology.

establish and implement protocols to optimise the x‑ray tube voltage and tube current‑exposure time product during the use of a dental cone beam computed tomography scanner on a patient;

perform the necessary tests and examinations on every newly installed dental cone beam computed tomography equipment prior to its use to ensure that the functions of the equipment (including the function to minimise any unnecessary exposure of any person to radiation while the equipment is being used) are operating normally; and

perform regular tests, checks and maintenance on every dental cone beam computed tomography equipment in accordance with the specifications by the manufacturer of the equipment to ensure that the functions of the equipment (including the function to minimise any unnecessary exposure of any person to radiation while the equipment is being used) are operating normally.
