To clarify the extent to which patients feel anxious about dental treatment, anonymized data of a self-completed questionnaire obtained at a dental clinic in Saitama Prefecture were used for this study. The subjects were 278 patients older than 15 years of age and who had given informed consent The questionnaire contained 71 questions concerning the following seven characteristic factors: sense of hearing, sense of sight, sense of smell, sense of taste, sense of touch, sense of pain, and other situations. Each question was rated on a four-point scale. Exploratory factor analysis of the 262 answers was performed with the principal factor method and normalized varimax rotation. Six factors were extracted using the Kaiser Criterion and the Screeplot These factors were interpreted as follows: anxiety before treatment, unpleasantness of pain and bleeding, unpleasantness of smell and taste or feeling of the tongue, a sound or appliance that recalled pain, a meaningful sound such as talking by the dentist, and an unpleasant sound from an appliance. The senses of smell, taste and touch in the oral cavity were extracted as the same factor. The sense of hearing was divided into the factor of dissonance and the factor of anxiety recalled by sound in memory. However, no factor concerning the stimulation of sight was extracted. Therefore, the sense of sight might be related with the recognition method of the patient based on past experience and knowledge.
为了明确患者对牙科治疗感到焦虑的程度，本研究使用了在埼玉县一家牙科诊所获取的自我填写问卷的匿名数据。研究对象为278名15岁以上且已签署知情同意书的患者。问卷包含71个关于以下七个特征因素的问题：听觉、视觉、嗅觉、味觉、触觉、痛觉及其他情况。每个问题按四点量表评分。采用主因子法和归一化方差最大旋转法对262份答案进行探索性因子分析。使用凯泽准则和碎石图提取六个因子。这些因子的解释如下：治疗前焦虑、疼痛和出血的不适感、嗅觉和味觉或舌部感觉的不适感、唤起疼痛的声音或器械、牙医谈话等有意义的声音以及器械发出的不愉快声音。口腔中的嗅觉、味觉和触觉被提取为同一因子。听觉被分为不和谐因子和记忆中声音唤起的焦虑因子。然而，未提取到与视觉刺激相关的因子。因此，视觉可能与患者基于过去经验和知识的认知方式有关。
