Printer-friendly versionPDF version


Radiographic examination forms a very integral part in oral diagnosis and greatly contributes to patient's treatment plan. There are guidelines for dental care practitioners in selection of appropriate radiographs for patients but even with these, radiographic examinations have been the norm with some dentists ordering radiographs based on the type of films available, patient's financial status as well as the costs of individual radiographs. At the moment there is scanty information on the magnitude of this problem. Studies that have been done show that use of the recommended guidelines has a significant potential for reducing both radiation exposure and health care costs without missing clinically significant disease while other studies in the developed world indicate use of individual selection criteria to determine which radiographs if any are required for screening new and recall patients. The aim of this study was to determine the selection criteria used for radiographic examination of patients visiting the University Dental Hospital. A descriptive cross-sectional study was carried out amo gpatients seen at the hospital in the period January to March 2003 who had radiographs taken after clinical examination. A sample size of 132 patients obtained by systematic random sampling was used out of which 3 were discarded due to insufficient information. Various variables were analysed; age, sex, type of patient, presenting complaints, diagnosis, type of radiographs and radiographic findings. Data analysis was done using MS-ACCESS and presented in form of tables and graphs. Out of the 129 record analysed, 56.6% of the patients were females while 43.4% were males. More than 50% of the patients were below 30 years of age. Most of the patients were recall patients and bitewing radiography was the most commonly utilised type of radiograph. There was no relationship between demographic characteristics, presenting complaint and radiographic examination. In conclusion it was found that radiographic examination was based on individual selection criteria depending on the patient's demonstrated need.
