From this database buy requip 0.25mg otc, accurate radiation dose estimations can be made for each imaging procedure discount 0.25 mg requip fast delivery, and this information may be included in the patient’s radiology report, if appropriate. In addition, this radiation database could result in robust radiology department quality assurance in radiation protection. A recent paper assessed the current status of patient radiation exposure tracking internationally and showed that no country has yet implemented a patient exposure tracking programme at a national level [14]. Eight countries (11%) indicated that a national patient tracking programme was being actively planned. There were some successfully established programmes at subnational or regional level. Education in radiation protection Education in radiation protection is a key priority and is important for all physicians including radiologists and other physicians who perform fluoroscopically guided procedures and other procedures which involve exposure to ionizing radiation. Radiation protection should, therefore, be introduced as a core competency in the undergraduate medical curriculum [15]. With regard to gastrointestinal imaging, recent studies have demonstrated that there is potential for substantial cumulative radiation doses from gastrointestinal imaging in groups of patients with chronic gastrointestinal disorders, e. Nonetheless, most dental radiology is performed outside radiology departments in independent practices, where self-referral is normal, paediatric patients form a large proportion of those exposed and quality assurance procedures may be lacking. While effective doses in well controlled research studies are quite low, dose audits suggest that the ‘real world’ situation is not so straightforward. In terms of justification, dentists are influenced in their use of diagnostic X rays by non-clinical factors. In terms of optimization, newer equipment and modified techniques should lead to lower doses, but their adoption is slow. The difficult challenges of radiation protection in dental radiology require efforts in education of dentists and increased awareness of evidence based guidelines, including audit of compliance with good practice. Regular dose audits and the setting of diagnostic reference levels are valuable tools, as long as they are followed by individualized feedback to dentists on optimization strategies. This is probably an underestimate, because most are performed by dentists in primary care outside public health care systems. In other words, dental radiology could be described as a high volume, low dose procedure. If the collective doses are so low, despite the relatively high numbers, then it could be argued that dental radiology has a trivial importance as far as radiation protection is concerned. First, as has already been said, most dental radiology takes place in primary care facilities without the supportive framework of medical physicist support and robust quality assurance programmes; this raises concerns about optimization of exposures. Second, unlike the rest of medicine, the use of X rays tends to be high in children and younger people for whom the risks are highest. Finally, dentists usually perform their own radiographic procedures; self-referral and the financial pressures to make X ray equipment pay for itself inevitably challenge the justification process [2]. The aim of this paper is to review the challenges around radiation protection in dental radiology and to highlight strategies for improvement. Supplementing this is panoramic radiography, developed in the 1940s–1950s, but which has grown substantially in use since the 1970s, with particular applications in assessing the developing dentition and in surgical procedures. Facial bone imaging using cephalography is mainly used as part of orthodontic assessment. Although analogue (film based) imaging is still widespread, digital systems are increasingly widespread and have become predominant in some developed countries. A recent review of the literature has confirmed this, at least for the simple radiographic techniques [4]. These figures must be viewed with caution; dosimetry performed as part of scientific studies presents results from modern equipment in carefully controlled situations. Where large studies have been performed on equipment in primary dental care, a wide range of radiation doses is revealed with an elongated tail at the high dose end [3, 5–12]. Payment, whether by the patient directly, through private insurance or public health service systems, is a motivation for intervention. While evidence for this is often anecdotal, recent research has shown the impact on prescription of radiography when a public health service payment system changed [13]. There are other, more subtle, pressures on dentists to use radiography; in particular, there can be fears of missing something and facing consequent medico-legal problems [14]. Dentists are strongly influenced by peer pressure to use X rays, patient expectations and by the teaching received in undergraduate training. As with medical radiology generally, there have been efforts to introduce guidelines (referral criteria) on prescription of diagnostic dental X ray examinations, for example, in Europe and in the United States of America [14, 15]. The quality of such guidelines varies, ranging from expert opinion of a small self-selected panel of individuals, through consensus statements of larger groups, to evidence based guidelines produced using robust methodologies. Guidelines are useless if they are not adopted and incorporated into the education of clinicians (undergraduate and continuing professional education).
