项目摘要

In order to clarify the relationship between onset of temporomandibular arthrosis and masticatory pattern, we conducted a comparative investigation of Hondurans and Xicaque, who are aboriginal Hondurans and have the same roots as Japanese.1. Methods and materials : Items investigated were frequency of temporomandibular arthrosis, dietary habits, dental attrition and morphological changes in the mandibular condyle. Subjects studied over two years from 1994 to 1995 were 60 Xicaque and 249 other Hondurans. Among them, 60 temporomandibular joints from the 31 Xicaque, 203 from 123 other Hondurans and 52 from 27 Lenqua were referred to via roentogenography.2. Results : In terms of dietary habits, 80.5% of Xicaque and 73.9% of other Hondurans prefer soft food, with these figures being roughly the same. 54.5% of the Xicaque and 29.4% of other Hondurans suffer temporomandibulararthrosis, and 22.7% of Xicaque and 4.2% of other Hondurans do not habitually brush their teeth, a considerable difference. In terms of dental attrition, Broca's classification I, II and III ratio were 5 : 7 : 3 for Xicaque, 5 : 4 : 4 for Lenqua and 3 : 8 : 2 for other Hondurans.In addition, based on preliminary research of 172 temporomandibular joints from American Indian skull/jaw bones owned by smithonian Museum, U.S.A., and the University of Michigan, results were obtained that as the Broca's classification advanced from I to II to III, the more the mandibular condyle morphology changed from round to convex to flat to ultraflat.The skeletal system, including the temporomandibular joint, of the Xicaque was found through X-rays to be not welldeveloped, compared to that of other Hondurans and Japanese. Remodeling of the condyle tended to be small.

为了阐明颞下颌关节病的发病与咀嚼模式的关系，我们对与日本人同根的原住民日本人和西雀人进行了比较研究。方法和材料：调查项目包括颞下颌关节病的发生率、饮食习惯、牙齿磨损和下颌髁突的形态变化。从1994年至1995年，对60名Xicaque人和249名其他埃塞俄比亚人进行了两年的研究。其中，60个颞下颌关节来自31个Xicaque人，203个来自123个其他人，52个来自27个Lenqua人。结果：在饮食习惯方面，喜查雀族80.5%的人和其他汉族73.9%的人喜欢吃软食，两者基本一致。锡察克族和其他蒙古族中分别有54.5%和29.4%的人患有颞下颌关节炎，锡察克族和其他蒙古族中分别有22.7%和4.2%的人不习惯刷牙，两者之间存在显著差异。在牙齿磨耗方面，Broca的I、II和III分类比例为：Xicaque 5：7：3，Lenqua 5：4：4，其他类牙颌骨3：8：2。此外，根据对美国smithonian博物馆172个美洲印第安人颅骨/颌骨颞下颌关节的初步研究，和密歇根大学的研究结果表明，随着Broca分类从I到II再到III，下颌骨髁状突形态从圆形到凸形到扁平到超扁平的变化越多。通过X线片发现，与其他蒙古人和日本人相比，Xicaque人的骨骼系统（包括颞下颌关节）发育不良。髁状突的重塑往往很小。
