主 题：LIPUS Periodontal bone defect Repair
摘 要：Objective:To investigate the repairing effect of low intensity pulsed ultrasound(LIPUS)on the Beagle canines periodontal bone defect.Methods:A total of 12 Beagle dogs with periodontal bone defect model were randomly divided into control group,LIPUS group,guided tissue regeneration(GTR)group and LIPUS+GTR group,with three in each.After completion of the models,no other proceeding was performed in control group;LIPUS group adopt direct exposure to radiation line LIPUS processing 1 week after modeling;GTR group adopted treatment with GTR,following the CTR standard operation reference;LIPUS+GTR group was treated with LIPUS joint GTR.Temperature change before treatment and histopathological change of periodontal tissue after repair was observed.Results:There was no significant difference in temperature changes of periodontal tissue between groups(P0.05).The amount and maturity of LIPUS+GTR group were superior to other groups;new cementum,dental periodontal bones of GTR group were superior to the control group but less than LIPUS group;new collagen and maturity of the control group is not high relatively.Conclusions:LIPUS can accelerate the calcium salt deposition and new bone maturation,thus it can serve as promoting periodontal tissue repair,and shortening the periodontal tissue repair time.
