Studies have shown anatomical and functional differences between men and women with respect to the mouth, pharynx, upper esophageal sphincter, and esophagus. The aim of this investigation was to analyze the influence of gender, body mass index (BMI), age, and orofacial anthropometric measurements on the intraoral maximum volume capacity for liquid. The investigation included asymptomatic subjects, 56 females and 44 males, aged 19-53 years. The volunteers sucked water through a straw up to the maximum tolerated oral volume, which was greater in men (71.2 ± 15.0 ml) than in women (55.4 ± 13.4 ml). Age, BMI, height, and number of teeth had no influence on the intraoral tolerated volume. Anthropometric orofacial measurements were greater in men than in women. In individuals with height between 1.66 and 1.89 m, anthropometric orofacial measurements were greater in men than in women, and the tolerated intraoral volume was greater in men than in women. There was a positive correlation between orofacial measurements and intraoral maximum volume. In conclusion, men have the capacity to place a larger volume of water inside their mouth than women. This observation is associated with higher anthropometric orofacial measures, but not with age, number of teeth, height, or BMI.
研究表明，男性和女性在口腔、咽、食管上括约肌和食管方面存在解剖和功能差异。本研究旨在分析性别、体重指数（BMI）、年龄和口面测量值对口内最大液体容量的影响。研究纳入了无症状受试者 56 名女性和 44 名男性，年龄 19-53 岁。志愿者通过吸管尽可能多地吸吮水，男性（71.2±15.0ml）的吸吮量大于女性（55.4±13.4ml）。年龄、BMI、身高和牙齿数量对可耐受的口腔容量没有影响。口面测量值男性大于女性。在身高 1.66 至 1.89 米的个体中，男性的口面测量值大于女性，男性的可耐受口腔容量也大于女性。口面测量值与口腔最大容量呈正相关。结论是，男性能够将更多的水放入口腔，这与较高的口面测量值有关，与年龄、牙齿数量、身高或 BMI 无关。
