Abstract:
:Fifteen subjects with complete natural dentitions were selected for investigation of their occlusal sounds on the left and right sides by means of power spectral analysis. It was found that the occlusal sounds consisted of various frequency components. Their mean power frequencies (MPF) and frequencies at 10, 20, 50, 80 and 90% of cumulative power (F10, F20, F50, F80, F90) on the left and right sides were almost identical (P greater than 0.05). The correlation coefficients between MPF and F50, MPF and F50 with the others were high. The results indicate that F20, MPF or F50 and F80 may be used as indices to describe the power spectral shape, and that power spectral analysis of occlusal sounds may be used as a contribution to diagnosis of occlusal conditions.
