摘要

吞咽困难是吞咽问题的医学术语,被定义为 "吞咽困难或吞咽物从咽部向胃部移动的障碍"。正常的吞咽分为以下三个阶段:1.口腔--将食物转化为囫囵吞咽物,然后输送到口腔后部。2.咽部--咽部吞咽快速而有序,在几秒钟内完成,推动食物通过咽部进入食道。在食物通过咽部时,喉和气管受到保护,以防止食物进入气道。呼吸会暂时停止,让声带合拢。3.食道--蠕动将食物通过食道,当食物接近胃时,下食道括约肌打开。

Dysphagia in adults and its relationship with oral health and dental treatment
Dysphagia is the medical term for swallowing problems and is defined as “difficulty in swallowing or impairment in the movement of swallowed material from the pharynx to the stomach”. Normal swallowing occurs in the following three phases: 1.Oral – the conversion of food into a bolus that is then transported to the back of the oral cavity. 2.Pharyngeal – pharyngeal swallow is rapid and sequential, occurring within seconds, propelling the bolus through the pharynx into the oesophagus. The larynx and trachea are protected from the pharynx during food passage to prevent the food from entering the airway. Breathing stops momentarily to allow the vocal folds to come together. 3.Oesophageal – peristalsis transports the bolus through the oesophagus, and the lower oesophageal sphincter opens as the bolus approaches the stomach.
