Abstract
We examined the effect of Bodysonic in order to find its relaxation effectiveness on the dentist after treating patients. We used a frequency analyzer of the electro-encepharogram (EEG) “IBVA” to judge the relaxation effects. This equipment can analyze the biolar lead of EEG from the frontal pole and also the oculer movement.
We conducted analaysis of EEG and the oculer movement record of the treatment time on children (Treatment), relaxation time using Bodysonic (RestB), and relaxation time not using Bodysonic (RestN). The subjects were 8 dentists working at our university (5 males,3 females, with a total of 30 experiments).5 of them were less than thirty years old while 3 of them were more than forty.
The summary of the results is shown below.
1) Reveral rate of Eye-movement was Treatment<RestN<RestB. The θ- wave and α- wave were RestN>RestB>Treatment, the β- low wave and β- high wave were RestB>RestN>Treatment.
2) As for the reveral rate of each index of treatment: Eye-movement was significantly different with those over 40 years old at P<0.01 and the θ- wave was at P<0.05. α- wave and β- low wave, β high-wave was significantly different from those under 30 years old at P<0.01.
3) For RestB: Eye-movement, θ- wave and β-low wave showed a higher rate for those under 30, while the α- wave and β- high wave showed a higher rate for those over 40 but neither of them showed any signifigant differences.
4) For RestN: Eye-movement, θ- wave and β- high wave showed a higher rate for those under 30, while α- wave and β- low wave showed a higher rate for those over 40 but neither of them showed any signifigant differences.
