【摘要】：土城子遺址是內(nèi)蒙古地區(qū)規(guī)模較大的古代城址之一,其地處陰山南麓、黃河北岸,是我國古代這一區(qū)域重要的政治、軍事、經(jīng)濟(jì)重鎮(zhèn)和交通文化中心。本文采用橫斷面描述性研究的方法,首次對吉林大學(xué)邊疆考古研究中心人類學(xué)實(shí)驗(yàn)室所收藏的該遺址出土的戰(zhàn)國時(shí)期149例個(gè)體顱骨標(biāo)本,共計(jì)2353顆恒牙進(jìn)行了各種口腔疾病的統(tǒng)計(jì)分析和研究,,獲得了當(dāng)時(shí)人群口腔疾病的相關(guān)數(shù)據(jù)。同時(shí)亦將結(jié)果與古今不同時(shí)代的人群進(jìn)行了對比分析和探討,一方面增加了我們對土城子戰(zhàn)國時(shí)期居民的體質(zhì)健康、飲食結(jié)構(gòu)和生存環(huán)境等方面的了解,一方面又為古人類口腔疾病的研究提供了相關(guān)的數(shù)據(jù)資料和線索。 本文共分八部分。 第一部分:前言。簡要介紹了有關(guān)牙齒研究的內(nèi)容、意義以及本文研究對象的相關(guān)情況。 第二部分:牙齒磨耗狀況研究。研究了牙齒的平均磨耗度、上下頜各個(gè)牙位磨耗的輕重以及牙齒磨耗是否存在年齡和性別差異。 第三部分:牙齒齲病狀況研究。研究了患齲率、齲齒率、根尖周病患病率等。隨著年齡的增長,患齲率、齲齒率和根尖周病患病率的發(fā)展趨勢以及年齡與齲病好發(fā)牙、好發(fā)牙面之間的關(guān)系。 第四部分:牙周病狀況研究。研究了牙周病患病率以及牙周病患病率與年齡、性別之間的關(guān)系。 第五部分:錯牙合畸形狀況研究。統(tǒng)計(jì)分析結(jié)果顯示,正常牙合的比例要小于錯牙合畸形所占的比例,而男性錯牙合畸形的患病率又要遠(yuǎn)高于女性。在Angle分類統(tǒng)計(jì)中,以I類錯牙合所占比例最大,其次為II類、III類。 第六部分:第三臼齒萌出狀況研究。研究了正位萌出率、先天缺失率、阻生率以及第三臼齒的萌出狀況是否存在性別和上下頜的差異。同時(shí)還對第三臼齒的阻生類型作了細(xì)致地觀察。 第七部分:其它觀察項(xiàng)目研究。對牙數(shù)異�，F(xiàn)象、鏟形門齒、生前牙齒脫落現(xiàn)象以及牙弓形狀作了統(tǒng)計(jì)分析。 第八部分:總結(jié)與討論。對前七部分進(jìn)行了總結(jié)和概括,并對牙齒各種疾病之間的相互關(guān)系進(jìn)行了探討。
[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.
