[Focal demineralization of the cortical plate of the jaw and its experimental reversibility based on microphotometry data].
Focal demineralization of bone tissue with local dosed vacuum (exposure of up to 20 sec) and 2% lithium chloride electrophoresis (8 sessions daily, 10 min exposure) was tried in 40 white rats (21 reference ones and 19 experimental). The maximal reduction of mineral content was achieved on days 3-7 after the end of the course and made up 76.2 +/- 15.0% (p less than 0.01) and 80.6 +/- 12.5% (p less than 0.001), respectively, as against the reference animals. Mineral content at the site of demineralization gradually normalized by day 21. This transient reduction of mineral content of bone tissue may be used in orthodontic treatment of dentition abnormalities.
