There is a scarcity of data regarding knowledge, attitudes and practices (KAP) of endodontists about cone-beam computed tomography (CBCT), which may be related to the lack of valid and reliable measures. The present study aimed to develop and validate a KAP measure about CBCT. The developed measure showed good content validity and was administered to 506 endodontists. Exploratory and confirmatory factor analysis revealed a factorial structure composed of three factors (KAP) with 13 items. The measure showed evidence of good internal consistency and discriminant validity, being able to accurately discriminate KAP according to the length of experience and level of education. Taken together, results provided evidence of good psychometric properties of a new KAP measure regarding CBCT, allowing future research in the field.
