Dental treatment causes dentists to many uncomfortable posture. However it is not clear whether or not, that fixing position of mannequin may cause stress to dentists. The secific aim of this study is to verify the relatdentists' posture and their stress.Twelve subjects were devided into two group. Control group(Adjustable) was allowed to adjust the position of mannequin during cuting teeth with high-speed rotary cutting instrument. Experimental group(Fixed) was not allowed to adjust the position of mannequin. Urine samples were collected at early morning, before experiment and after experiment. Urine samples were again collected each morning for 2 days to establish control data baseline. Concentrations of creatinine, 17-OHCS, 17-KS-S and catecholamine(adrenaline, noradrenaline) were measured. Creatinine ratios of 17-OHCS, 17-KS-S and catecholamine were calculated. Posture of the subjects who cut teeth with high-speed rotary cutting instrument were taken at angles from both side and back. Experimental and control levels were compared and analyzed statistically using ANOVA about urine and posture.The result was as follows.In some measurement angle of posture significant difference was found between control group and experimental group(p<0.001).There was no significant change of creatinine ratio on any of the neuroendocrine hormones (p<0.05). This suggests that fixing position of mannequin may cause difference of posture but fixing position of mannequin may not cause stress to dentists.

牙科治疗导致牙医许多不舒服的姿势。然而，目前尚不清楚人体模型的固定位置是否会对牙科医生造成压力。本研究的目的在于探讨牙科医师的工作姿势与工作压力，并将12位被试分为两组。对照组（可调组）在高速旋转切削器切削牙体时，可调节人体模型的位置。实验组（固定）不允许调整人体模型的位置。分别于清晨、实验前、实验后采集尿样。每天早晨再次采集尿样，持续2天，以建立对照数据基线。测量肌酐、17-OHCS、17-KS-S和儿茶酚胺（肾上腺素、去甲肾上腺素）的浓度。计算17-OHCS、17-KS-S和儿茶酚胺的肌酐比值。用高速旋转切削器切削牙齿的受试者，从两侧和背部角度拍摄照片。结果表明，在某些体位测量角度上，实验组与对照组之间有显著性差异（p<0.001），而肌酐比值对神经内分泌激素无显著性影响（p <0.05）。这表明人体模型的固定位置可能会导致姿势的差异，但人体模型的固定位置可能不会对牙科医生造成压力。
