摘　　要：目的探讨正常成人的上下颌第一恒磨牙的牙髓血流量(pulpal blood flow,PBF)在生理状态下的“临床正常参考值范围”,为临床诊疗工作提供参考依据。方法按照激光多普勒血流检测仪的工作原理及操作注意事项,对正常成人上下颌健康第一恒磨牙采用激光多普勒血流检测仪检测其PBF值,分析计算其生理状态下的临床正常参考值范围。统计分析PBF值在不同性别、不同牙位和上下颌间的差异性。结果招募正常成人志愿者共200人,其中平均年龄(22.76±3.26)岁,男性95人,女性105人,第一恒磨牙总数800颗。无论是男性还是女性,第一恒磨牙左侧和右侧PBF检测值差异无统计学意义(P>0.05),上、下颌第一恒磨牙PBF检测值差异无统计学意义(P>0.05)。第一恒磨牙PBF值的性别差异具有统计学意义(P<0.05),女性第一恒磨牙PBF值较男性高,男性PBF临床正常参考值范围为(8.56±3.25)PU,女性PBF临床正常参考值范围为(9.51±3.47)PU。结论LDF检测正常成人第一恒磨牙PBF值女性较男性高,同性别的左右侧、上下颌第一恒磨牙PBF值无差异,其均可作为对照牙的参照选择。Objective To explore the"clinical normal reference range"of pulpal blood flow(PBF)in the physiological state in an effort to provide a reference for clinical diagnosis and treatment.Methods According to the working principle and operational considerations of laser Doppler flowmetry(LDF),the PBF blood flow value of the first molars of the upper and lower mandibles of normal adults was detected by LDF,and the clinical reference value range under physiological conditions was analyzed and calculated.The differences in PBF values by sex,dental position and location(left and right side,upper and lower jaw)were analyzed.Results A total of 200 normal adult participants with an average age of(22.76±3.26)years were included.The cohort included 95 males and 105 females,with a total of 800 first molars.Neither the PBF values of the left and right first molars nor the PBF values of the upper and lower first molars in males or females significantly differed(P>0.05).The PBF value for females was higher than that of males.Specifically,the clinical reference PBF values for males and females were(8.56±3.25)PU and(9.51±3.47)PU,respectively.Conclusion The PBF values of normal adult first molars in healthy subjects were higher in females than in males,and in the PBF values of first molars of the same sex did not significantly differ between the left side and right side or upper and lower jaw;these values could be used as a reference for the selection of control teeth.
