In our study was aimed to determine pretreatment the state-trait anxiety levels and to compare current socio-demographic status with satisfaction after treatment of the patients with endodontic treatment was not applied previously. 69 were male and 81 female of the 150 patients with root-canal treatment planned were invited to participate in this study. After the recording general characteristics of the patients (age, gender, education level), Spielberger "State-Trait Anxiety Inventory" (STAI) questionnaire, can measure state and trait anxiety values, was administered to the patients.

The relationship between age, gender and education level with state anxiety, trait anxiety and post-treatment VAPSS score, correlation coefficients and statistical significance were examined using Spearman's test.Kruskal-Wallis test and Mann-Whitney U test were used to investigate for the significant differences within groups. Between the age groups, the 45-60 age group was (p=0,007); between the gender groups, the women were (p=0,001); between the education level of the group, high school or equivalent levels was (p<0,001) identified more anxious, significantly. Endodontic treatment increases the anxiety level of patients. In this respect, there is a need for comprehensive and detailed research which is attuned to culturally.
