Chewing and swallowing are physiologically interconnected functions, which share motor structures and supranuclear regions of the central nervous system (CNS), involving a sensorimotor synchrony. To analyze the influence of masticatory behavior on muscular compensations in the oral phase of swallowing in smokers compared with nonsmokers. A cross-sectional study comparing smokers and nonsmokers composed of 24 participants in each group. The aspects of food crunching, masticatory pattern, masticatory speed, atypical muscular contractions, and lip closure were analyzed during mastication. In swallowing, aspects of contraction of the orbicular and mental muscles, head movement and presence of deglutition, mastication, smoking, and of stomatognathic system of residues after swallowing were characterized. Statistically significant differences were identified between the study groups related to food grinding pattern, masticatory velocity, and mental contraction during swallowing. There was no significant association between masticatory function and compensations during swallowing. Differences were observed in the pattern of chewing and swallowing in smokers compared with nonsmokers, but no influence of masticatory performance was observed in the presence of muscle compensations during the oral phase of swallowing.
咀嚼和吞咽是生理上相互关联的功能，它们共享中枢神经系统（CNS）的运动结构和核上区域，涉及感觉运动同步。
为了分析与不吸烟者相比，咀嚼行为对吸烟者吞咽口腔期肌肉代偿的影响。
一项横断面研究，比较吸烟者和不吸烟者，每组24名参与者。在咀嚼过程中分析食物咀嚼、咀嚼模式、咀嚼速度、非典型肌肉收缩和唇部闭合等方面。在吞咽过程中，对口轮匝肌和颏肌的收缩、头部运动以及吞咽、咀嚼、吸烟情况和吞咽后口腔颌面部系统残留物的情况进行了特征描述。
研究组之间在食物研磨模式、咀嚼速度和吞咽时颏肌收缩方面存在统计学上的显著差异。咀嚼功能与吞咽时的代偿之间没有显著关联。
与不吸烟者相比，吸烟者在咀嚼和吞咽模式上存在差异，但在吞咽口腔期出现肌肉代偿时未观察到咀嚼性能的影响。
