The purpose of this study was to investigate the ability of the pulsed Nd:YAG laser in removing broken instruments. In the first experiment, the number of laser irradiation cycles required to decompose 3 mm tips of stainless steel and Ni-Ti K-files at an output of 900 mJ/l pps was measured. In the second experiment, sixteen extracted human mandibular teeth were used. The 3 mm tip of a stainless steel K-file was fractured artificially at the middle or the apical third in the mesial root canal of a mandibular molar, and removal of the fractured instrument was attempted by pulsed Nd:YAG laser irradiation (output energy : 900 mj/l pps). In addition, the temperature elevation on the root surface was evaluated by thermography. The results were as follows: 1) The number laser irradiation cycles required to decompose 3 mm tips of stainless steel and Ni-Ti K-file averaged 34 times and 45 times, respectively. 2) In 8 cases where the file was fractured artificially at the middle in the root canal, the fractured instruments were not completely removed by laser irradiation. The file tip was bypassed in 7 out of 8 cases and a ledge was created in one case by laser irradiation. 3) In 4 out of 8 cases where the file was fractured artificially at the apical third in the root canal, the fractured instruments were completely removed by laser irradiation. The file tip was bypassed in 2 cases and a ledge and perforation were created in one case each by laser irradiation. The temperature elevation on the root surface was below an average of 10°C during laser irradiation. Our results suggested that pulsed Nd:YAG laser was useful for the removal of the broken instrument in the root canal.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"4787","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IMAI,
