Abstract
This paper presents the first results of clinical application of YAG:Er laser ('Lasma-1', Laser Center IFMO, Russia) in practical dental procedures performed in Russian clinics. YAG:Er laser operating in free-running mode has been used for in-vivo restorative dentistry. Caries cavities of various types has been treated in contact mode with applied water pulse irrigation of a treatment zone. The paper announces the results of laser treatment of caries cases (426 fillings). 104 patients have been involved in. 396 fillings have been made for non-complicated caries, 30 fillings -- for pulpits and periodontits. In the process of laser treatment it has been observed no pain perception, even in a case of deep caries. The paper reports the results of investigation of patients tooth reaction on several thermal effects immediately after the treatment and 6 months later. Results of electro- odontometry and roentgenography of teeth processed with laser radiation of 2.94 mkm wavelength are demonstrated. Particular attention is given to the quality of filling material adhesion to walls of a laser cavity and conditions of contact points. The last is observed for cavities of III and IV classes.
