摘要:AIM: Evaluation of tongue movements during swallowing with a computer-aided, M-mode ultrasonography system in combination with a cushioning device. SUBJECTS AND

METHOD: Motion pattern and activity duration of the tongue dorsum during swallowing were investigated in 55 volunteers. RESULTS: The duration, amplitude and pattern of tongue movements during swallowing differed

interindividually, whereas they were reproduced well intra-individually. We thus observed three

characteristic variations in phases I and IIIb and two in phases IIb and IIIa. The movement pattern in phase IIa and in the rest phase was uniform. CONCLUSIONS: M-mode ultrasonography provides valid information on

tongue movements without any side-effects and is thus a useful tool in the diagnosis and research of tongue functions in orthodontics and dentistry.
