Ultrasonographic images of tongue movement during mastication.

摘要: We observed vertical motion of the tongue during mastication in ultrasonographic images 6 males with an average age 28.7 years. All subjects had complete dentition and no evidence neurological disorders. used a 7 MHz mechanical convex scanning transducer to obtain continuous, real-time ultrasonic image tongue, carried out B-mode observation at median sagittal plane mandible. recorded M-mode on line connecting mandibular first molars. The produced good quality dorsal surface peanuts, rice, crackers, boiled fish paste, pickled radishes, pudding bananas. transducer, which was small light, permitted capture videotape without manual placement scanner. Continuous showed that turned food, mixed it saliva, sorted unsuitable particles aided bolus formation. Vertical two phases, sorting
