A study of the parallel relationship between the occlusal plane and the line connecting nasal alar and tragus was made in 90 dentulous cases by using cephalometry. The results show that the line connecting the inferior point of nasal alar and the mid-point of tragus runs much more parallel with the occlusal plane. The regression equation reveals a "line of(More)
OBJECTIVE To investigate the effects of task probability on context processing using AX-type continuous performance test (AX-CPT) and event-related potential (ERP). METHODS We set 3 groups of complementary probabilities (AX/AY: 0.55/0.15, 0.35/0.35, and 0.15/0.55) for AX task and AY task and kept the probability 0.15 for both BX and BY tasks. Eighteen(More)

The biting force value of normal teeth of 770 human subjects were measured by electric resistance strain gnathodynamometer. 365 were males, and 405 females. Their ages ranged from 13 to 49. The results showed that the biting force value of males is larger than that of the females (P < 0.01). In the males, the biting force value of those aged 13-16 gradually(More)
