What radiographs should dentists prescribe for recall patients?
Again, the principle of ALARA applies and dentists must perform a clinical examination before prescribing additional radiographs. Dentists should base their decision about the number, type and frequency of radiographs at recall appointments on existing disease and the expected occurrence of disease. For example, dentists should determine the frequency of bitewing radiographs on the basis of caries risk assessment. A decision about radiographs should never be based on inflexible time periods alone, (such as bitewing radiographs every six months).
