Root resection of endodontically treated teeth by erbium: YAG laser radiation.
Root resection was performed on endodontically treated extracted human teeth exposed to pulsed erbium:YAG laser radiation at energy levels between 50 and 90 mJ/pulse in wet and dry fields. The lased surfaces were examined by optical and scanning electron microscopy. The smooth, clean resected root surfaces, devoid of charring (in wet fields), indicate that the erbium:YAG laser has a potential application in endodontic periapical procedures. In addition, researchers have shown that the zone of thermal damage and carbonization following erbium laser exposure on soft tissues and bone is appreciably less compared with other lasers, and therefore its use may result in improved healing and diminished postoperative discomfort.
