Gastric emptying rate in subjects with malocclusion examined by [13C] breath test

错(牙合)患者的咀嚼功能明显低于正常(牙合)患者。虽然一些研究表明咀嚼功能影响胃肠道消化功能，但错牙合与胃肠道症状之间的关系尚未得到广泛研究。我们假设咀嚼功能不足会增加胃的功能负担，并对胃肠道系统产生一些影响。本研究的目的是研究错(牙合)患者的咀嚼功能和胃排空率。11名健康的齿状女性志愿者和11名错牙合的女性患者接受了流食13C-醋酸盐呼气试验。比较两组患者13CO2最大呼气时间(Tmax)。错(牙合)组的平均Tmax明显长于正常(牙合)组。

Masticatory function is significantly lower in individuals with malocclusion than in those with normal occlusion. Although several studies suggest that masticatory function influences gastrointestinal digestive function, the relationship between malocclusion and gastrointestinal symptoms has not been studied extensively. We hypothesized that insufficient masticatory function would increase the functional burden of the stomach and have some influence on the gastrointestinal system. The purpose of this study was to investigate masticatory function and gastric emptying rate in subjects with malocclusion. Eleven healthy dentate female volunteers and eleven female patients with malocclusion underwent a 13C-acetate breath test with a liquid meal. Maximum 13CO2 exhalation time (Tmax) was compared statistically between both groups. The mean Tmax of the malocclusion group was significantly longer than that of the normal occlusion group.
