The effect of electroacupuncture stimulation applied to a unilateral Ho-ku point on the human tooth pain thresholds was studied by electrically stimulating bilateral canines. In six of ten subjects tested, the tooth pain threshold was elevated ipsilaterally but was unchanged contralaterally during and after the electroacupuncture. In the remaining four,(More)
The mechanism of the dimensional increase in demineralized dentine crystals was investigated using a high-resolution transmission electron microscope. Lattice fringes were observed even in the demineralized crystals. The characteristics of demineralized dentine crystals mainly consisted of a partial disappearance of their lattice fringes along their lateral(More)
The present study was carried out to investigate the relationship between the relative humidity and the electrical resistivity of enamel in vitro. The electrical resistivity of enamel samples was measured in a thermo-hygrostat where the relative humidity varied between 60% and 90%, with the measurements carried out first in a descending direction and then(More)
