摘　　要：目的利用CBCT测量牙周不同情况下汉族、维吾尔族两民族右侧下颌第一磨牙牙冠硬组织相关厚度,观察不同民族人群中在不同牙周情况下、不同性别、不同年龄下的牙冠硬组织是否存有差异,从而提供一定临床治疗依据。方法收集来自新疆医科大学第一附属医院320例就医者的CBCT图像资料,汉族、维吾尔族各160例。测量两民族右侧下颌相关硬组织的厚度对测量数据进行统计分析。结果汉族、维吾尔族男性和女性、不同年龄组、牙周炎组和健康人群、以及不同牙周炎严重程度下下颌第一磨牙牙冠硬组织厚度例髓室顶牙本质的厚度、髓室底的厚度、髓室的高度、近中髓角上方牙冠硬组织的厚度、中央窝-髓室顶的厚度差异有统计学意义(P<0.05),远中髓角上方牙冠硬组织的厚度、釉质牙本质界-根分叉距离差异无统计学意义(P>0.05),男性的下颌第一磨牙牙冠硬组织厚度高于女性,汉族的下颌第一磨牙牙冠硬组织厚度高于维吾尔族。年龄的增长和牙周炎严重程度的增加一定程度上也影响牙冠硬组织相关指标。结论民族差异性有可能造成下颌第一磨牙牙冠硬组织在性别、年龄、牙齿健康状态和牙周炎、不同牙周炎严重情况下CBCT影像的差异。建立相关数据库后发现,民族的差异性可能影响造成牙冠硬组织厚度的差异性。Objective CBCT was used to measure the thickness of the hard tissue of the crown of the right mandibular first molar of Han and Uyghur under different periodontal conditions,so as to provide certain clinical treatment basis for the possibility of future dental tissue lesions and the difference in the influence of different ethnic groups on dental tissue under different classification.Methods CBCT image data of 320 patients from the First Affiliated Hospital of Xinjiang Medical University were collected,including 160 Han and 160 Uyghur patients respectively.The thickness of the right mandibular related hard tissue was measured and the measured data were statistically analyzed.Results The crown hard tissue thickness of the first molar of the mandible in the Han and Uygur nationalities,different age groups,periodontitis group and healthy people,and different periodontitis severity cases had statistically significant differences in the dentin thickness of the pulp top,the thickness of the pulp bottom,the height of the pulp,the crown hard tissue thickness of the mesial angle,and the central fossa-pulp top(P<0.05),but there was no statistically significant difference in the crown hard tissue thickness of the distal angle,and the enamel dentin boundary-root bifurcation thickness(P>0.05).The thickness of hard tissue of the mandibular first molar crown was higher in male than in female,and higher in Han than in Uyghur.The increasing of age and periodontitis severity also affect the coronal hard tissue index to some extent.Conclusions Ethnic differences may lead to differences in CBCT images of hard crown tissue of mandibular first molar in gender,age,dental health status,periodontitis and different severe periodontitis.After the establishment of the relevant database,it was found that the difference of nationalities may affect the difference of the thickness of the hard tissue of the dental crown.
