“…According to a previous study, the presence of radio-opaque materials, such as gutta-percha or artificial crowns, can create artifacts and make interpretation of the image more difficult. 3 Future studies should evaluate filled root canals combined with new tools in CBCT software. Due to the great variety of tools commercially available that can handle images, it is necessary to test whether these are useful for diagnostic imaging.…”

“…In addition, the prognosis is poor and dental extraction is imminent when the fracture is not diagnosed at an early stage. [1][2][3] Incomplete longitudinal root fractures or those with no separation of fragments are difficult to identify on periapical radiographs. The superimposition of adjacent tissues may obscure the visibility of the fracture line.…”

Objectives: To determine whether cone beam CT (CBCT) enhancement filters influence the diagnosis of longitudinal root fractures. Methods: 40 extracted human posterior teeth were endodontically prepared, and fractures with no separation of fragments were made in 20 teeth of this sample. The teeth were placed in a dry mandible and scanned using a Classic i-CAT® CBCT device (Imaging Sciences International, Inc., Hatfield, PA). Evaluations were performed with and without CBCT filters (Sharpen Mild, Sharpen Super Mild, S9, Sharpen, Sharpen 3 3 3, Angio Sharpen Medium 5 3 5, Angio Sharpen High 5 3 5 and Shadow 3 3 3) by three oral radiologists. Inter-and intraobserver agreement was calculated by the kappa test. Accuracy, sensitivity, specificity and positive and negative predictive values were determined. McNemar test was applied for agreement between all images vs the gold standard and original images vs images with filters (p , 0.05). Results: Means of intraobserver agreement ranged from good to excellent. Angio Sharpen Medium 5 3 5 filter obtained the highest positive predictive value (80.0%) and specificity value (76.5%). Angio Sharpen High 5 3 5 filter obtained the highest sensitivity (78.9%) and accuracy (77.5%) value. Negative predictive value was the highest (82.9%) for S9 filter. The McNemar test showed no statistically significant differences between images with and without CBCT filters (p . 0.05). Conclusions: Although no statistical differences was observed in the diagnosis of root fractures when using filters, these filters seem to improve diagnostic capacity for longitudinal root fractures. Further in vitro studies with endodontic-treated teeth and research in vivo should be considered.

“…To simulate soft tissues, we used five types of materials in three diverse thicknesses. Both material type and thickness have been widely used 2,5,6,9,10,15,16 with aims to simulate the real anatomical structures. 27,28 In this study, we showed that both the material type and the thickness tested influenced the gain of density in bone tissue as demonstrated by DSR.…”

A R T I C L E I N F O INTRODUCTIONCone Beam Computed Tomography is a technique consisting of X-ray computed tomography the X-rays are divergent, forming a cone. introduced first in the European market in 1996. dimensional imaging techniques have been used since 1896. CBCT imaging is one of the recent techniques that is makes way to visualize the object in an equal planes three dimensionally. It is of low cost and of lower radiation exposure compared with conventional CT. CBCT helps in determining the root canal morphology by removal of the superimposed structures and showing normal anatomy and morphology of the root canal system without additional exposure with higher resolution. Conventional Imaging Techniques and Its LimitationsRadiography is essential for treatment of the pulp pathologies, bio-mechanical preparation of the root canal during RCT, obturation, and also in healing assessment. Imaging is needed in all stages of endodontic procedures. (4) Assessment, the morphology of the tooth including location and number of canals, pulp chamber size and degree of calcification, root structure, direction and curvature, fractures, and the extent of dental caries can be observed only by imagining techniques, mostly radiographs. During therapy two radiographs may be performed. The first is for working length determination which is done by inserting files into the root canals to a length approximating till the apex. Second one is the 'master cone radiograph' which is done after bio mechanical preparation to check the fit of the master cone.
