Shortwave diathermy (SWD) is a therapeutic device, accepted to be one of the most widely employed clinical modalities. It is employed in dentistry to treat oral and maxillofacial diseases, chronic periodontitis, taste disorders, and oral submucous fibrosis. SWD should not be used on patients who have any implanted metallic lead or any implanted system that can contain lead. In dentistry, most of the restorative materials and appliances contain metallic compound. Hence, the use of SWD is constrained in dentistry.
