-Abstract-
Recently, the magnetic force has been considered as a method for a more effect for a
more efficient tooth movement. The purpose of this study was to evaluate the effect of
different static magnetic fields of ND-Fe-B magnet on MC3T3-E1 cells by measuring
the alkaline phosphatase activity and observing the amount of stained alkaline
phosphatase. For measuring of alkaline phosphatase activity, MC3T3-E1 cells were
seeded in first and third row of 12 well culture plate. And Nd-Fe-B magnets were
positioned under the first column of first and third row to apply different static
magnetic fields(first column:100mT ; second column:4.6mT ; third column:0.5mT ; forth
column:0.0mT) to the cells for 7, 13, 19, and 25 days. For staining of alkaline
phosphatase, MC3T3-E1 cells were seeded in 100mm culture plates. And Nd-Fe-B
magnets were positioned under the corner of plates to apply different static magnetic
fields(magnet side:100mT ; the opposite side:0.5mT) to the cells for 7, 13, 19 and 25
days.
The results were as follows :
1. ALP activity was increased until day 19 in biochemical determination as well as in
histochemical staining.
2. The application of higher magnetic field(100mT) suppressed ALP activity at day 13,
19, 25. On the contrary, the application of the lower magnetic field(4.6mT, 0.5mT)
significantly enhanced the ALP activity.
3. Consistent with enzyme assay, histochemical staining of ALP also demonstrated that
higher magnetic field(100mT) suppressed ALP activity, lower one(0.5mT) enhanced.
