| Research Abstract |
The respiration pattern of the edentate during swallowing was demonstrated that post-swallow expiration pattern was prevalent. Therefore, there was a significantly difference rate of respiration pattern between the edentate and the younger dentate. With regard to the prevalence of the respiration pattern of edentulous denture wearers during swallowing, under the condition with the dentures, the post-swallow inspiration pattern was few prevalence pattern. However, under the condition without dentures, the prevalence of the pre-swallow expiration and post-swallow inspiration pattern increased. Moreover, the pre- and post-swallow inspiration pattern was also observed in some patients, although this pattern was not observed at all while patients were wearing their dentures. Since there were more respiration pattern in which respiration after swallowing resumes with inspiration when not wearing dentures than when wearing dentures, there is a possibility that this respiration pattern could become a risk factor for aspiration while not wearing dentures.
