The effect of pulpotomy using CO2 and Nd:YAG laser on dental pulp tissue
The histological response of the dental pulp after laser irradiation was studied. After pulpotomy was performed in the premolar and molar teeth of dogs, the exposed pulp tissue at the root canal opening was either CO2 otr Nd:YAG laser. The laser parameters were 2W, 10 ms 5 times per second for 1, 2 and 3 s for CO2 laser and 2W, 20 pulses per seconbd for 1, 2 and 3 s for Nd:YAG laser. Observation was made 30 and 45 days after treatment. The results revealed that laser irradiation caused carbonization, necrosis, infiltratzion of inflammation cells, oedema ane haemorrhage in the pulp tissue. Under the conditions of this experiment, there was little histological evidence of repair to the treated pulp with a newly formed dentine barrier, which was in contrast to the control samples treated with a calcium hydroxide-containing cement (Dycal)
