Evidence-based guidelines. Available at: “https://ec The radiation dose in CBCT will be briefly reviewed. The European Commission's Evidence Based Guidelines prepared by the SEDENTEXCT Project Consortium will be summarised, and (in)appropriate use of CBCT will be illustrated for various dental applications. fp7,sedentexct,fission-2007-3.2-01,the university of manchester(uk),leeds test objects limited(uk),ethniko kai kapodistriako panepistimio athinon(el),universitatea de medicina si farmacie iuliu hatieganu cluj-napoca(ro),vilniaus universitetas(lt),katholieke universiteit leuven(be),malmo universitet(se) Last year evidence-based guidelines for cone beam CT (CBCT) were published as part of the SEDENTEXCT project. The guideline is an extensive document that covers many aspect of this developing area.

ATOMMAX Diagnostic Dental Head Phantom CIRS 711-HN, Dental Image Quality Test Tool, SedentexCT, and Leeds Test Objects. The SEDENTEXCT (safety andefficacyof anew andemerging dental x-ray modality) guidelines have illustrated principles for use of CBCT in dentistry, including justification and optimiza-tion of x-ray exposures. 12 To overcome difficulties posed by new CT technologies and correct dose underestimation produced by the CTDI method, 4 A protocol proposed by SEDENTEXCT, dose index 1 (DI1), was applied to dose measurements obtained using a thimble ionization chamber and cylindrical PMMA dose index phantom (SEDENTEXCT DI). Dose distributions were obtained using Gafchromic film. Results: The image noise was 6-12.5% which, when normalized to the difference of mean voxel value of PMMA cylinder with; – 160 mm diameter – 144 mm length – density 1.20 ¡À 0.01 g/cm3 The body of the cylinder allows the following test to be undertaken; Noise/Uniformity – The upper and lower sections of the phantom are uniform PMMA (density 1.20 ¡À 1.00%) The test feature in the centre of the cylinder is included to perform the following measurement; Pixel Intensity Value – 25 mm SedentexCT IQ SedentexCTIQ consists of a PMMA cylinder (160 mm diameter) with recesses to house test inserts (fig. 1).
