A. Moritz et al., ND-YAG LASER IRRADIATION OF INFECTED ROOT CANALS IN COMBINATION WITH MICROBIOLOGICAL EXAMINATIONS, The Journal of the American Dental Association, 128(11), 1997, pp. 1525-1530
In this in vivo study, 30 subjects with infected root canals were trea
ted with the neodymium: yttrium-aluminum-garnet, or Nd:YAG, laser usin
g standard laser settings and procedures. In microbiological examinati
ons conducted before irradiation, the authors found streptococci in 30
cases and staphylococci in 15 cases. After the first irradiation, the
authors found that 19 root canals showed minimal streptococcal growth
and 10 root canals showed minimal staphylococcal growth.
