 note = {P(論文), Dentists require precise skills during operations in limited space, e.g. inside a molar. In consequence, they are prone to have stress thereafter. To find out what the cause of the stress is, analyses were performed on 28 students in the 5^<th> year of Ohu University, Dental School. In these experiments, as non-parametric statistic analysis was appropriate for the purpose, the subjects could be divided into 2 groups, high- and low-stress ones. Nervous sweating, blood flow rate and the pulse rate during each of 5 trials of simulating operations with Dent Sim were measured in the subjects as indicators of stress. Results were : 1. A relationship between sweat volumes and trials : Most subjects of the high-stress group showed more than 0.150 mg/cm^2/min in the first trial of the operation, and less than that value according as the trial was repeated. On the other hand, in the low-stress group, sweat volumes ranged between 0.061 and 0.072 mg/cm^2/min through the trials. The former volumes were significantly higher th an the latter through the trials. 2. A relationship between the periods of the operation and trial times : The average operation periods in the first trial for the high- and low-stress groups were 259 and 361 sec, respectively, while those in the fifth trial were 170 and 215 sec. This difference between the two groups may depend on neatness of the latter group. 3. A relationship between the assessment scores with Dent Sim and experience (training) : The average scores in the first trial for the high- and low-stress groups were 62.5 and 65.5, respectively, while those in the fifth trial were 67.5 and 69.0, respectively. There was significant difference between the two groups for the first trial, but not in the fifth. 4. The locations causing stress for the operators during cavity preparation in a molar were estimated as the center of the lateral ventricle, the labial side and the center of the central portion of the cavity for the high-stress group. However, whole central portion in the molar caused stress for the low-stress one. In conclusion, these findings suggest that training sessions of dental care is critical for reducing stress of operators, and important to improve their skills.},
