本研究的目的是确定是否可以通过皮肤传导性的弱电流客观地测量焦虑。进行了三次测量。首先，一个标准化的牙科焦虑问卷，以确定焦虑。第二，测量皮肤电传导。第三，记录测谎仪对问卷中三个关键问题的回答。这些关键问题的问卷分数被用来创建两组：焦虑和不焦虑。这三个关键问题都经过了测谎仪的验证。在第一次分析中，如果测谎仪测试显示在三个关键问题中的任何一个上撒谎，则患者被排除在外。第二项分析是在逐个问题的基础上排除说谎者。第三次分析忽略了测谎仪。在所有病例中，皮肤电导和牙科焦虑之间存在统计学显著相关性。数据似乎表明，对注射的恐惧是现代牙科最令人焦虑的方面。
The purpose of this study was to determine if anxiety can be measured objectively by skin conductance of a weak electric current. Three measurements were taken. First, a standardized dental-anxiety questionnaire was given to determine anxiety. Second, galvanic skin conductance was measured. Third, polygraph responses were recorded to three key questions from the questionnaire. Questionnaire scores of these key questions were used to create two groups: anxious and not-anxious. The three key questions were subjected to polygraph verification. In the first analysis patients were excluded if the polygraph test disclosed lying on any of the three key questions. The second analysis excluded liars on a question-by-question basis. The third analysis disregarded the polygraph. A statistically significant correlation was found between skin conductance and dental anxiety in all cases. Data seem to indicate that fear of injection is the most anxiety-producing aspect of modern dentistry.
