{"title":"EFFECT OF ACUTE NASAL OBSTRUCTION ON MASTICATORY FUNCTION","authors":"M. Sugawara, I. Oota, N. Sakaguchi, M. Asaka, S. Igarashi, K. Inomata","doi":"10.14858/SOSHAKU1991.8.66","DOIUrl":"https://doi.org/10.14858/SOSHAKU1991.8.66","url":null,"abstract":"The present study was undertaken to examine how masticatory function is affected by an acute nasal obstruction. Nasal obstruction was performed by pinching the nose of each subject with a nose clip. We measured the chewing time, water content of food bolus and the volume of saliva secreted during the mastication of peanuts. In addition, the chewing cycle time, burst duration time and the interval time were also analyzed from the results obtained electromyographically. Comparisons were made between the normal and the nasal obstructed condition in the same subject. The chewing time under nasal obstructed condition was significantly prolonged compared to control condition, whereas the water content of food bolus and volume of saliva secreted during mastication was unchanged. The chewing cycle time tended to be prolonged by nasal obstruction. The interval time was significantly prolonged by nasal obstruction, while the burst discharge time was not significantly changed. These results indicate that the water content of food bolus as an important factor for the determination of the chewing time under a nasal obstructed condition as well as in a normal condition. Therefore, the prolongation of chewing time under a nasal obstructed condition is possibly attributed to a compensatory action for getting an equivalent water content of food bolus under normal condition. Key word: Acute nasal obstruction, Water content of food, EMG, Masticatory function, Introduction Numerous investigators have reported that masticatory function is affected by various factors. The chewing force, the number of chewing strokes and the time until swallowing vary according to the texture of food, such as its hardness, shape and stickiness (Shiere and Manly, 1952; Kawamura and Nobuhara, 1957; Thexton et al., 1980; Liao et al., 1990). The volume of saliva secreted during mastication depends on the water and taste substances containing food (Watanabe and Dawes, 1988; Watanabe et al., 1993a; Watanabe et al., 1998). However, most of these studies have been carried out on healthy subjects. There is little information about the effect of acute nasal obstruction on masticatory function. The conryzal type of cold easily gives rise to the acute nasal obstruction. The present study was undertaken to examine how masticatory function is affected by an acute nasal obstruction. Based on the results, we have reported the effect of acute nasal obstruction on masticatory function , especially the effect on chewing time. Materials and Methods 1.
