Pulsed Nd:YAG laser irradiation of the tooth pulp in the cat: I. Effect of spot lasing

Effects of CO2 Laser Irradiation of the Gingiva during Tooth Movement

“…Thus, CGRP neurons appeared to be involved in periodontal tissue remodeling induced by orthodontic force. It has been reported that spot irradiation with a pulsed Nd:YAG laser risked producing nerve injury and irreversible tissue damage (Tokita et al, 2000). CO 2 laser irradiation might also injure the nerves and influence the distribution of PGP 9.5 and CGRPpositive nerves.…”

Lasers in nonsurgical periodontal therapy

“…Nonetheless, it is always necessary to bear in mind that, at a high energy level on oral tissues, the Nd:YAG laser will penetrate into deeper tissues of the target site. In particular, when the irradiation is directed perpendicular to the target, this deep penetration may occasionally cause unexpected thermal damage in the tooth pulp (196), alveolar bone, and other surrounding tissues. Spencer et al.…”

Lasers and soft tissue: 'fixed' soft tissue surgery

“…This risk can exist through the penetration of short wavelengths or the conductive heat effects arising from long wavelength char that is super-heated. [5][6][7][8][9] It is advisable, therefore, to assess the thickness, vascularity and position of any target 6,[10][11][12] during the removal of a giant cell granuloma. Laser therapy has been cited as a possible modality in treating this condition.…”
