The aim was to study the relation between risk attitude and knowledge in technical, patient-oriented, and organizationally related behavior within oral radiology. A questionnaire was mailed to 2000 randomly selected dentists listed in the register of the Swedish Dental Society, with a response rate of 69.3%. Regression analysis was used for analyzing the effects of the independent variables knowledge, risk attitude, continuing education in oral radiology, counties with specialists in oral radiology, type of practice, work experience, and sex on three categories of dependent variables: 1) technical behaviors: type of film, type of collimator, dose level, frequency of change of chemicals; 2) patient-oriented behaviors: use of patient protection barriers, strict indications for performing full-mouth X-ray examinations and bitewing radiography on new patients and recall patients; and 3) organizationally related behaviors: delegation of X-ray examinations to dental auxiliaries, influence on choice of collimator, influence on choice of film. Knowledge and education had strong direct effects for most of the dependent variables. The technical behaviors were mainly influenced by knowledge, education, and risk attitude, while organizationally related behaviors were influenced by type of practice and sex. The patient-oriented behaviors were influenced by a number of independent variables, such as education, type of practice, work experience, and sex. The present results indicate that both knowledge and the organizational context of dentists influence work.
目的是研究口腔放射学中技术、以患者为导向以及组织相关行为方面的风险态度与知识之间的关系。向瑞典牙科协会登记册中随机抽取的2000名牙医邮寄了一份问卷，回复率为69.3%。采用回归分析来分析自变量知识、风险态度、口腔放射学继续教育、有口腔放射学专家的县、执业类型、工作经验和性别对三类因变量的影响：1）技术行为：胶片类型、准直器类型、剂量水平、化学药品更换频率；2）以患者为导向的行为：使用患者防护屏障、对新患者和复诊患者进行全口X线检查和咬合翼片摄影的严格指征；3）组织相关行为：将X线检查委托给牙科辅助人员、对准直器选择的影响、对胶片选择的影响。知识和教育对大多数因变量有很强的直接影响。技术行为主要受知识、教育和风险态度的影响，而组织相关行为受执业类型和性别的影响。以患者为导向的行为受多个自变量的影响，如教育、执业类型、工作经验和性别。目前的结果表明，牙医的知识和组织背景都会影响工作。
