Abstract

<p><b>Abstract : </b>Periapical periodontitis is considered to be caused by infectious agents persisting in the root canal system triggering the host immune reaction. Disinfection is the key point for endodontic treatment, but it is difficult to completely remove all causal agents from the root canal system because of the morphological complexities. In this study, we focused on the potential usefulness of electro-magnetic wave irradiation (EMWI) for clinical application to promote healing. The aims of this study were : 1) to determine the characteristics of EMW and 2) to evaluate the clinical application of EMWI to endodontic treatment. The analysis of EMW characteristics demonstrated that it is important to make the diameter of the active electrode tip smaller and to keep the insertion depth within 5 mm for effective generation of Joule heat, and revealed that Joule heat conduction spreads 1.0-1.5 mm wide in the horizontal direction. The success rate of clinical application of EMWI was 99.1%, which is higher than that of the EMWI-untreated group (95.1%). Moreover, the reduction rate of the diameter of periapical lesion in the EMWI-treated group (75.62%) was significantly increased. These findings demonstrate that EMWI accelerates healing of periapical lesions and suggest that it may be useful for clinical application to refractory periapical periodontitis as non-surgical treatment.</p>
