【摘要】：土城子遗址是内蒙古地区规模较大的古代城址之一,其地处阴山南麓、黄河北岸,是我国古代这一区域重要的政治、军事、经济重镇和交通文化中心。本文采用横断面描述性研究的方法,首次对吉林大学边疆考古研究中心人类学实验室所收藏的该遗址出土的战国时期149例个体颅骨标本,共计2353颗恒牙进行了各种口腔疾病的统计分析和研究,,获得了当时人群口腔疾病的相关数据。同时亦将结果与古今不同时代的人群进行了对比分析和探讨,一方面增加了我们对土城子战国时期居民的体质健康、饮食结构和生存环境等方面的了解,一方面又为古人类口腔疾病的研究提供了相关的数据资料和线索。本文共分八部分。第一部分:前言。简要介绍了有关牙齿研究的内容、意义以及本文研究对象的相关情况。第二部分:牙齿磨耗状况研究。研究了牙齿的平均磨耗度、上下颌各个牙位磨耗的轻重以及牙齿磨耗是否存在年龄和性别差异。第三部分:牙齿龋病状况研究。研究了患龋率、龋齿率、根尖周病患病率等。随着年龄的增长,患龋率、龋齿率和根尖周病患病率的发展趋势以及年龄与龋病好发牙、好发牙面之间的关系。第四部分:牙周病状况研究。研究了牙周病患病率以及牙周病患病率与年龄、性别之间的关系。第五部分:错牙合畸形状况研究。统计分析结果显示,正常牙合的比例要小于错牙合畸形所占的比例,而男性错牙合畸形的患病率又要远高于女性。在Angle分类统计中,以I类错牙合所占比例最大,其次为II类、III类。第六部分:第三臼齿萌出状况研究。研究了正位萌出率、先天缺失率、阻生率以及第三臼齿的萌出状况是否存在性别和上下颌的差异。同时还对第三臼齿的阻生类型作了细致地观察。第七部分:其它观察项目研究。对牙数异常现象、铲形门齿、生前牙齿脱落现象以及牙弓形状作了统计分析。第八部分:总结与讨论。对前七部分进行了总结和概括,并对牙齿各种疾病之间的相互关系进行了探讨。
[Abstract]:Tuchengzi site is one of the largest ancient city sites in Inner Mongolia. It is located at the southern foot of Yinshan Mountain and on the north bank of Yellow River. It is an important political, military, economic and cultural center in ancient China. In this paper, 149 individual skull specimens unearthed from the site during the warring States period were collected by the Anthropology Laboratory of the Frontier Archaeological Research Center of Jilin University for the first time using the method of cross-sectional descriptive study. A total of 2353 permanent teeth were statistically analyzed and studied on various oral diseases, and relevant data of oral diseases were obtained. At the same time, the results were compared and analyzed with the people of different ages. On the one hand, it increased our understanding of the residents' physical health, diet structure and living environment during the Tuchengzi and warring States period. On the one hand, it provides relevant data and clues for the study of ancient human oral diseases. This paper is divided into eight parts. The first part: preface. This paper briefly introduces the content and significance of tooth research and the related situation of the research object in this paper. The second part: the study of tooth wear. The average wear degree of teeth, the magnitude of wear in each position of upper and lower teeth, and the age and gender difference of tooth wear were studied. The third part: dental caries status. The incidence of caries, dental caries and periapical disease were studied. With the increase of age, the development trend of caries rate, dental caries rate and periapical disease prevalence, and the relationship between age and dental caries, hair surface. The fourth part: the study of periodontal disease. The prevalence of periodontal disease and the relationship between the prevalence of periodontal disease and age and sex were studied. Part five: the study of malocclusion. The results of statistical analysis showed that the proportion of malocclusion was smaller than that of malocclusion, and the prevalence of malocclusion in males was much higher than that in females. In Angle classification, the proportion of class I malocclusion was the largest, followed by class II and class III. Part six: a study of the eruption of the third molar. Whether there are gender and mandibular differences in the incidence of orthostatic eruption, congenital absence rate, impaction rate and the eruption of the third molar were studied. At the same time, the impacted type of the third molar was carefully observed. The seventh part: other observation project research. The abnormal number of teeth, spade incisor, tooth loss and arch shape were analyzed statistically. Part eight: summary and discussion. The first seven parts are summarized and the relationship between tooth diseases is discussed.
