Significance of Laser on the Endodntic Treatment

Abstract

In the application of laser to the area of endodntics, we have the problem that the object of laser treatment is narrow area. Especially to treat a root canal, we have the difficulties on both the guide of laser beam and the irradiating direction of laser. Moreover during the irradiation of laser beam at an apical area, if we applied the laser beam to the apical tissue through the apical foramen, the apical tissue was wounded. Then the patient will feel the pain. Although the laser treatment has these problems on the area of endodntics, we will get the development on the promotion of care and the establishment of painless treatment. But if we can't exhibit the cause of disease, we should not do the aimless laser irradiation to avoid the spreading of pain.
