摘　　要：目的利用锥形束电子计算机断层扫描(CBCT)调查榆林地区中年人群磨牙髓石发生情况。方法收集2020年9月至2021年9月于榆林市第一医院行CBCT检查的400名(3200颗磨牙)受检者资料。比较不同牙位、牙弓的磨牙髓石发生率及不同性别、年龄受检者的磨牙髓石患病率。结果3200颗磨牙中,共有841颗磨牙发生髓石,髓石发生率为26.28%;右侧上颌第一磨牙、左侧上颌第一磨牙、左侧下颌第一磨牙、右侧下颌第一磨牙、右侧上颌第二磨牙、左侧上颌第二磨牙、左侧下颌第二磨牙、右侧下颌第二磨牙髓石发生率比较,差异具有统计学意义(P<0.05);上颌第一磨牙髓石发生率高于下颌第一磨牙、上颌第二磨牙及下颌第二磨牙,差异具有统计学意义(P<0.05);第一磨牙髓石发生率高于第二磨牙,差异具有统计学意义(P<0.05);上颌磨牙髓石发生率高于下颌,差异具有统计学意义(P<0.05);左、右侧磨牙髓石发生率比较,差异无统计学意义(P>0.05)。400名受检者中,188名存在磨牙髓石,髓石发生率为47.00%;女性的磨牙髓石患病率高于男性,差异具有统计学意义(P<0.05);不同年龄段受检者的磨牙髓石患病率比较,差异无统计学意义(P>0.05)。结论髓石多发于女性、上颌磨牙及第一磨牙,上颌第一磨牙是磨牙中髓石发生率最高的牙齿,在临床治疗过程中应多加注意。Objective To investigate the incidence of molar pulp stones in middle-aged population in Yulin area by cone-beam computed tomography(CBCT).Methods The data of 400 objects(3200 molars)who underwent CBCT examination in the First Hospital of Yulin from September 2020 to September 2021 were collected.The incidence of molar pulp stones in different teeth and dental arches and the incidence of molar pulp stones of different genders and ages were compared.Results Among the 3200 molars,a total of 841 molars had pulp stones,and the incidence of pulp stones was 26.28%;there were statistically significant differences in the incidence of pulp stones between the right maxillary first molar,the left maxillary first molar,the left mandibular first molar,the right mandibular first molar,the right maxillary second molar,the left maxillary second molar,the left mandibular second molar and the right mandibular second molar(P<0.05);the incidence of pulp stones in the maxillary first molar was higher than that in the mandibular first molar,maxillary second molar and mandibular second molar,and the differences were statistically significant(P<0.05);the incidence of pulp stones in the first molar was higher than that in the second molar,and the difference was statistically significant(P<0.05);the incidence of pulp stones in the maxillary molars was higher than that in the mandibular,and the difference was statistically significant(P<0.05);there was no significant difference in the incidence of pulp stones between the left and right molars(P>0.05).Of the 400 objects,188 had molar pulp stones,and the incidence of pulp stones was 47.00%;the prevalence of molar pulp stones in women was higher than that in men,and the difference was statistically significant(P<0.05);there was no significant difference in the prevalence of molar pulp stones among different age groups(P>0.05).Conclusion Pulp stones are more common in women,maxillary molars and first molars.The maxillary first molar is the tooth with the highest incidence of pulp stones in the
