Abstract

Due to the fact that studies regarding the dynamic features of natural frequency (NF) have not yet been systematically discussed up to the present time, therefore, modal analysis was carried out in this study to test the frequencies of incisors, canies, first premolar and first molar. A total number of 1007 teeth were tested based on tooth morphology, location, age and gender to analyze the effects of the above mentioned physiological factors to the natural frequency of the sample teeth. Our results showed that no significant difference in the natural frequency was found among teeth in four different quadrants. However, tooth anatomy, age and gender imposed an effect on the NF value of teeth. Regardless of teeth anatomy, NF value of teeth in female subjects was found to be apparently higher than the male counterpart by approximately 100Hz (p
