<title>Erbium laser radiation action onto dental tissues</title>

Abstract

AbstractsThe paper presents the results of electron-microscopy study of dental tissues, prepared by erbium laser radiation. Improvement of methods of non-complicated caries treatment in the therapeutic dentistiy clinics, aimed onto pain factor elimination, is of primaiy importance. The reason is the preservation even in the case of fast or tuibo drills use of pain, produced by most of manipulations due to pressure, vibration or heating of the prepared dental tissues.The most prospective from the point of view of dental treatment laser radiation wavelength iS that of erbium iaser nearbi the range of 3jm (2.69-2.94im). The reason is that this wave1engh is close to one of the main absorption bands of water1' resulting in significant absorption of this radiation by dental tissues ,' Processed parts of the tooth are thuS efficiently extracted without damage to adjacent regions 512, and heating is local7'13. Laser preparation by laser radiation with wavelength in another ranges of spectrum results in significant variation of the adjacent tissues and pathology variation of dental pulp. We have discussed in details comparative properties of different radiation wavelengths action in dentistiy in our pape?.
