When searching on any specialty, it is advisable to search not only the specialty or area of knowledge (in this case Radiography, Dental) but also search under a disease state such as Dental Caries and the anatomical structure Tooth, Deciduous and add the subheading Radiography. All of these are MeSH (Medical Subject Headings) terms that you can combine using AND/OR in MEDLINE. Keep in mind that you can also "explode" these terms to include more specific terms. In the case of Radiography, Dental the term 'explodes' to include more specific terms including Bitewing, Digital, Panoramic and Sialography.
