Introduction: The prevalence of dental anxiety appears to be relatively consistent throughout the world, but some studies reports higher levels than others. This may be related to different instruments used. Objective: to identify and describe the main instruments used in the assessment of dental anxiety in adolescents. Material and Methods: Literature review. Original studies involving adolescents, in which the methodology comprised the application of some instrument to identify and / or quantify the phenomenon, were included. The search was limited to English, Portuguese and Spanish publications in the period between 2012 and 2016. Reviews, Meta-analyzes and case reports were excluded. The selected databases were MEDLINE (via PubMed) and LILACS (via BVS); and the search was developed with the following descriptors: 'dental anxiety', 'adolescents', 'Surveys and Questionnaires' (MeSH), combined by the Boolean operator AND. Results: Ten psychometric instruments are available to assess dental anxiety. The most frequently used instrument is the Dental Anxiety Scale (DAS), presented in nine studies. Less frequently used is the Facial Image Scale (FIS), presented in only one investigation. Most of the instruments affords translations into other languages, including Portuguese. Conclusion: The most used instrument is the DAS, followed by its modified version, the MDAS. Usually, more than one instrument has been used to correlate the findings and to provide the measured construct a greater consistency.Descriptors: Dental Anxiety; Adolescent; Surveys and Questionnaires.ReferencesStenebrand A, Wide Boman U, Hakeberg M.
