Abstract：
OBJECTIVE: Oral function in patients with schizophrenia has not been well-characterized. To address this, we performed a cross-sectional study of oral function in Japanese inpatients with schizophrenia.
METHODS: We measured oral function, including occlusal force, tongue-lip motor function, tongue pressure, and masticatory function in 130 Japanese inpatients with schizophrenia. We then compared the frequency of clinical signs of oral hypofunction among 63 non-elderly and 67 elderly inpatients with schizophrenia, as well as data from 98 elderly control participants from a previous Japanese study.
RESULTS: The frequency of reduced occlusal force was significantly higher in the elderly inpatients (76.2%) than in the non-elderly inpatients (43.9%) and elderly controls (43.9%). The frequency of decreased tongue-lip motor function in non-elderly inpatients (96.8%) and elderly inpatients (97.0%) was significantly higher than that in elderly controls (56.1%). The frequency of decreased tongue pressure in non-elderly inpatients (66.1%) and elderly inpatients (80.7%) was significantly higher than that in elderly controls (43.9%). Finally, the frequency of decreased masticatory function was highest in elderly inpatients (76.5%), followed by non-elderly inpatients (54.8%) and elderly controls (15.3%).
CONCLUSIONS: Oral function was decreased in both non-elderly and elderly Japanese inpatients with schizophrenia compared with elderly controls.

摘要：
目的：精神分裂症患者的口腔功能尚未得到很好的表征。为了解决这个问题，我们对日本精神分裂症住院患者的口腔功能进行了横断面研究.
方法：我们测量了口腔功能，包括咬合力,舌唇运动功能，舌头的压力,130名日本精神分裂症住院患者的咀嚼功能。然后，我们比较了63名非老年和67名老年住院精神分裂症患者的口腔功能减退临床体征的频率，以及先前日本研究中98名老年对照参与者的数据。
结果：老年住院患者（76.2%）的咬合力降低频率明显高于非老年住院患者（43.9%）和老年对照组（43.9%）。非老年住院患者(96.8%)和老年住院患者(97.0%)舌唇运动功能下降频率明显高于老年对照组(56.1%)。非老年住院患者(66.1%)和老年住院患者(80.7%)舌压下降频率明显高于老年对照组(43.9%)。最后,老年住院患者咀嚼功能下降的频率最高(76.5%)，其次是非老年住院患者(54.8%)和老年对照组(15.3%).
结论：与老年对照组相比，非老年和老年日本精神分裂症住院患者的口腔功能均下降。
