The aim of the study <br />was to assess the efficacy of Nd:YAG laser irradiation on permanent <br />molar root canal disinfection and follow up of the healing process. <br />The Nd:YAG laser system, emitting at a wavelength of 1064 nm, <br />was applied for 46 and 36 numbered root canal for three times <br />(1.5 W, 15 Hz, 5s) in working length of a 10-year-old girl patient <br />with caries cavities extended to the pulp and extensive periapical <br />radiolucency. At the third session of Nd:YAG laser application the <br />patient was asymptomatic. After two years, the clinical and <br />radiographic follow up revealed that the patient was asymptomatic <br />and the periapical tissues and restored tooth were healthy. The <br />Nd:YAG laser irradiation is not an alternative but a possible <br />supplement to existing protocols for root canal disinfection. </p>}, number={2}, publisher={Marmara University}
