          Abstract

          RESUMEN Introducción: La tomografía computarizada de haz cónico (CBCT, del inglés Cone-Beam Computed Tomography) se ha masificado en odontología, incluyendo ortodoncia. Organismos internacionales proponen guías para la indicación de CBCT en odontología. Hasta la fecha no existen publicaciones que recopilen y analicen las guías actuales de uso de CBCT en ortodoncia. El propósito de la presente revisión narrativa es analizar las indicaciones de CBCT en ortodoncia en revisiones sistemáticas y guías actuales de organismos internacionales. Materiales y métodos: Se realizó una búsqueda principal en PubMed, Web of Science y Scopus. Para la búsqueda complementaria se usaron las listas de referencias de los artículos incluidos a texto completo obtenidos de la búsqueda principal y sitios web oficiales de instituciones guías de uso de CBCT en ortodoncia. Los criterios de inclusión correspondieron a guías, y revisiones sistemáticas sobre el uso de CBCT en ortodoncias no incluidas en las referencias de las guías, en idioma inglés. Resultados: Se encontraron 7 guías y 1 revisión sistemática. La CBCT no se recomienda para uso rutinario ni como examen imagenológico inicial en ortodoncia. Sus usos son en su mayoría para casos particulares, en que la radiografía convencional no aporta información suficiente para un correcto diagnóstico y posterior tratamiento. Conclusión: Las organizaciones internacionales concuerdan que la CBCT en ortodoncia se justifica solo cuando beneficia al paciente. La CBCT es una herramienta diagnóstica confiable en casos donde la evaluación en tres dimensiones es obligatoria para tomar la decisión terapéutica más adecuada. Aún falta nueva evidencia en esta área, la que debe considerar los principios de protección radiológica de optimización y justificación.

          ABSTRACT Introduction: Cone-beam computed tomography (CBCT) has been popularized in dentistry, including orthodontics. International organizations have published guidelines for the use of CBCT in dentistry. To date, there are no publications that compile and analyze the current guidelines for the use of CBCT in orthodontics. The aim of this narrative review is to analyze the indications for CBCT in orthodontics both in systematic reviews and current guidelines from international organizations. Materials and methods: A main search was conducted in PubMed, Web of Science, and Scopus. For the complementary search, the reference lists of the articles included in full text obtained from the main search and official websites of institutions with guidelines for the use of CBCT in orthodontics, were used. The inclusion criteria corresponded to guides on the use of CBCT in orthodontics, and systematic reviews not included in the references of the guides, in English. Review: Seven guidelines and one systematic review were found. CBCT is not recommended for routine use or as an initial imaging examination in orthodontics. The uses are mostly for particular cases, in which conventional radiography does not provide the information for a correct diagnosis and subsequent treatment. Conclusions: There is a consensus among international organizations regarding the use of CBCT in orthodontics, justifying its use only when it provides a benefit to the patient. CBCT is a reliable diagnostic tool in cases where three-dimensional evaluation is mandatory to take the most appropriate therapeutic decision. New evidence is still lacking in this area, which must consider the principles of optimization and exam justification.

          The Efficacy of Diagnostic Imaging

          The authors discuss the assessment of the contribution of diagnostic imaging to the patient management process. A hierarchical model of efficacy is presented as an organizing structure for appraisal of the literature on efficacy of imaging. Demonstration of efficacy at each lower level in this hierarchy is logically necessary, but not sufficient, to assure efficacy at higher levels. Level 1 concerns technical quality of the images; Level 2 addresses diagnostic accuracy, sensitivity, and specificity associated with interpretation of the images. Next, Level 3 focuses on whether the information produces change in the referring physician's diagnostic thinking. Such a change is a logical prerequisite for Level 4 efficacy, which concerns effect on the patient management plan. Level 5 efficacy studies measure (or compute) effect of the information on patient outcomes. Finally, at Level 6, analyses examine societal costs and benefits of a diagnostic imaging technology. The pioneering contributions of Dr. Lee B. Lusted in the study of diagnostic imaging efficacy are highlighted.

            Cone-beam CT in paediatric dentistry: DIMITRA project position statement.

            DIMITRA (dentomaxillofacial paediatric imaging: an investigation towards low-dose radiation induced risks) is a European multicenter and multidisciplinary project focused on optimizing cone-beam CT exposures for children and adolescents. With increasing use of cone-beam CT for dentomaxillofacial diagnostics, concern arises regarding radiation risks associated with this imaging modality, especially for children. Research evidence concerning cone-beam CT indications in children remains limited, while reports mention inconsistent recommendations for dose reduction. Furthermore, there is no paper using the combined and integrated information on the required indication-oriented image quality and the related patient dose levels. In this paper, therefore, the authors initiate an integrated approach based on current evidence regarding image quality and dose, together with the expertise of DIMITRA's members searching for a state of the art. The aim of this DIMITRA position statement is to provide indication-oriented and patient-specific recommendations regarding the main cone-beam CT applications in the pediatric field. The authors will review this position statement document when results regarding multidisciplinary approaches evolve, in a period of 5 years or earlier.

              Cone beam computed tomography in dentomaxillofacial radiology: a two-decade overview.

              The aim of this study was to evaluate and summarise features of currently and formerly available cone beam CT (CBCT) devices from 1996 to 2019. Additionally, a recommendation for standardised reporting of CBCT characteristics was provided.
