Comparison of the Thermogenesis and Cauterization of Oral Mucosa Tissues of Denlaser 800 Laser Initiated between Two Kinds of Laser Initiator
Objective:To compare the effect of two laser initiators on the thermal performance of Denlaser 800 laser and cautery effect of oral mucosa and soft tissue.Methods:The two laser initiators were dropped on the slide in equal amounts and the galvanometer was installed at the bottom of the slide to measure the temperature.Laser irradiation for ten seconds,at the end of ten seconds to record the temperature of the galvanometer.The same amount of methyl violet liquid and ink juice were coated on the front 1/2 of the back of the tongue of experimental mice,and the same laser was used to irradiate the experimental part coated with light sensitive agent under the same parameter conditions.The tissue computer of the experimental area was used to measure the burning area.Results:The average temperature increase of methyl violet absorption Denlaser 800 laser was 101.4℃,and the average temperature increase of ink was 86.8 ℃.The increase temperature of methyl violet absorption Denlaser800 laser was higher than that of ink(P＜0.05).The cautery area of coated methylene violet mucosa was significantly larger than that of ink juice and laser mucosa.The cautery area of the mucous tissue ir-radiated by methyl violet liquid combined with low dose laser was significantly larger than that of the mucous tissue irradiated by high dose laser alone,and slightly larger than that of the mucous tissue irradiated by high dose laser of ink juice.Conclusion:Methylene violet is better than ink initiator for Denlaser800 laser thermal performance,photoinitiator can increase the effect of laser on oral mucosa,methylene violet is better than ink juice,it is an ideal light sensitive agent in stomatology.
