Objective: The aim of this study is to investigate the
effects of low intensity pulsed ultrasound on orthodontic tooth movement in
rats.
Methods:
For this study,
40 12-week-old adult male Wistar albino rats from the Animal Laboratory at
Adnan Menderes University, Faculty of Medicine, were used. Rats were divided into four groups of ten. Group 1 was
the untreated control group. In group 2, an orthodontic spring was used to move
teeth. In groups 3 and 4, orthodontic treatment was combined with low intensity pulsed ultrasound at 16
J/cm2 or 48 J/cm2, respectively, for 14 days. Tooth
movement was measured on day 14. Serum bone alkaline phosphatase (BALP) and
C-telopeptide of type I collagen (CTX-I) levels were analyzed biochemically.
The number of osteoclasts, osteoblasts and inflammatory cells, capillary
density and new bone formation was determined histologically. Receptor activator
of nuclear factor-kappa B ligand (RANKL), osteoprotegerin (OPG), vascular
endothelial growth factor (VGEF) and transforming growth factor-β (TGF-β) were
assessed using immunohistochemical staining.
Results:
BALP and CTX-I levels in group 4 were significantly higher than for group 1.
Tooth movement and the number of osteoclasts, inflammatory cells, and capillary
density in group 4 were significantly greater than for group 2. The intensity
levels of RANKL and OPG in group 4 were significantly greater than for group 2.
Conclusion: Ultrasound is noninvasive application and a
promising therapy for accelerating bone remodeling during orthodontic tooth
movement.
