Radiographic examination forms an integral part of clinical dentistry, with some form of radiographs necessary on the majority of patients. Intra-oral periapical (IOPA) radiographs form the backbone of imaging for diagnosis and follow-up of various dento-facial pathologies. However, certain patient populations are unable to tolerate intra-oral films/sensors due to various reasons. A not-so recent development called extra-oral periapical (EOPA) radiography may be a useful adjuvant to such a situation, at least in the near future. It is essentially a technique where the film is placed extra-orally overlying the tooth of interest. The following manuscript is an attempt to throw light on this technique and the impact it may have on various disciplines of dental practices. The advantages and disadvantages of EOPA radiography and it′s comparison to IOPA radiography has been discussed.
