AB  - <p><strong>Objective</strong>: The aim of this study was to develop the Turkish version of the Index of Dental Anxiety and Fear (IDAF-4C<sup>+</sup>) and also to explore factors associated with dental anxiety in clinical pediatric dental patients (PDPs). <strong>Study Design</strong>: The study sample consisted of 421 PDPs aged 12–14, 104 of whom were selected for test-retest analysis. The psychometric evaluation included linguistic validity, exploratory factor analysis, reliability by internal consistency (Cronbach's alpha) and test-retest reliability (intra-class correlation coefficient, ICC). Construct validity was tested by comparing a commonly used instrument, the Children's Fear Survey Schedule Dental Subscale (CFSS-DS). Associations between parental dental anxiety, frequency of dental visits, dental caries, dental visit behaviour and children's dental anxiety were also examined. <strong>Results:</strong> The Turkish version of the IDAF-4C demonstrated good internal consistency (Cronbach's alpha α=.96) and test-retest reliability (ICC=.87). Factor analysis showed a fit IDAF-4C model with a single factor, 8 items. Dental anxiety scores were significantly correlated with all measured variables (p&lt;0.001). Girls showed significantly higher dental anxiety scores than boys (p&lt;0.05). <strong>Conclusions</strong>: This study suggests that the Turkish version of the IDAF-4C<sup>+</sup> is a valid and reliable instrument for assessing dental anxiety and fear in Turkish children.</p>
