dc.description.resumoAIM: This study aimed to present a laboratory device used for obtain standardized X-ray images and used for analysis of resin composites using two radiographic methods and two imaging process data. METHODS AND MATERIALS: The device with lead protection and glass visor that stabilize the x-ray tube and permitted the stabilization of the samples and different x-Ray films and sensors was created. Specimens with 5.0mm in diameter and 2.0mm in thickness of 2 nanohybrid (Filtek Z350, 3M-ESPE and Vittra APS, FGM) and 4 bulk fill composites (Filtek Bulk fill Posterior, 3M-ESPE, Opus Bulk Fill Regular (FGM), Opus Bulk fill flow (FGM), and Tetric Evoceram Bulk fill (Ivoclar Vivadent) were tested. The x-ray images were obtained positioning one sample for each resin composite and aluminium step wedge over two sensors: direct digital sensor (Acteon) and Phosphor Plate (VistaScan, Dürr Dental). Images were analysed using two software’s (Image J and DBSWIN, Dürr Dental) to calculate the radiopacity level comparing resin composites and also with the aluminium step wedge. Data were analysed by three-way ANOVA followed by Tukey test (=0.05). RESULTS: The developed devise was efficient to protect secondary radiation and to standardize the x-ray images. All resin composite showed recommended radiopacity level irrespective of the radiographic method or software analysis. CONCLUSION: Bulk fill and conventional composite resins exhibit variability in radiopacity, with values considered above the dentin values. Radiographic methods and software tested showed similarity ranking capacity for radiopacity of the composite resins, changing only the calculated values. The device was able to standardize the different radiographic methods used in this in vitro study to assess radiopacity of restorative materials.pt_BR
