Study on prevention of incidents of trainee dentists using psychological tests

为预防实习牙医的医疗事故，对2005年和2006年毕业的101名（31名男性和70名女性）二级实习牙医的实际医疗事故进行了调查。调查时间为2005年和2006年。1）实习牙医年度医疗事故统计表2005年有26.5%的实习牙医报告了医疗事故，2006年约有19.2%的实习牙医报告了医疗事故。在这些病例中，有6例是口腔内被切割器械损伤，4例是在治疗完成后或根管治疗期间感到不适，以及其他病例。2005年和2006年，几乎没有病人因医疗事故而留下后遗症，而几乎发生事故的比例分别为69.4%和75.0%。2）心理特征分析63.0%的牙科医生SDS在正常范围内，无抑郁倾向，4.0%的牙科医生有中度抑郁倾向。至于CMI，约87.6%在正常范围内，没有神经质倾向，2.0%的牙医有IV区。在MAS中，约72.0%的患者没有明显的主观焦虑倾向。特质焦虑在STAI中占37.9%。在四种心理测验中，发生医疗事故组与未发生医疗事故组之间的差异均不显著。受试者数量太少，无法证实这些趋势，因此，积累病例非常重要。

For the purpose of preventing medical accidents by trainee dentists, actual incidents of medical accidents were investigated in 101 (31 males and 70 females) second grade trainee dentists who graduated in 2005 and 2006. Investigation term was 2005 and 2006. Their psychological conditions were also analyzed using four types of psychological tests, which included SDS, CMI, MAS, and STAI.1) Annual tabulation of medical accidents by trainee dentistsAccidents were reported by 26.5% of the trainee dentists in 2005 and about 19.2% in 2006. In breaking these down, there were six cases of damage inside the mouth by a cutting device, four cases of patients who felt unwell after completion of the treatment or during root canal treatment, as well as others. There were no patients who experienced a sequelae due to a medical accident.Near miss was experienced about 69.4% of the time in 2005 and about 75.0% in 2006. In the order of the highest in number, there were bar's putting on and off in 31 cases, damage by the turbine bar in 17 cases (multiple answers in each case), just to name a few.2) Analyses of psychological featuresAs for SDS, about 63.0% were within the normal range without a depressive tendency and there were 4.0% dentists with moderate depressive tendency. As for CMI, about 87.6% were within the normal range without a neurotic tendency and were 2.0% dentists with a IV area. In MAS, a subjective manifest anxiety tendency was absent in about 72.0%. In STAI, trait anxiety was high in about37.9%. The differences were hardly seen between one group with medical accidents and another group without them in four types of psychological tests. The number of subjects was too small to confirm these tendencies, it will therefore be important to accumulate the cases.
