Figure 3 showed the pictures of tongue at rest and 
after mastication. The tongue was a convex shape at 
rest. Each image indicated a close resemblance of 
Shape and showed similar positions. The tongue 
position was fairly constant within the individuals, 
regardless of the first and the second measurements 
(Fig 4). The measurement error, expressed as a 
percentage of the mean between both measurements, was 
1. 45%. High reproducibility was indicated. The both 
images of the measurement of points at rest position 
and peanut mastication after swallowing position 
indicated a close resemblance of shape and showed 
similar positions (Fig 3). The tongue position was 
fairly constant within the individuals, regardless of 
the rest before or after the masticatory movements 
(Fig 4).
