“…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.

“…Clinical and radiographic evidence of the presence of root fractures does not always present itself until the fracture has been present for some time. However, even with longstanding VRF clinical signs of their existence maybe little more than a draining buccal sinus (83), which is certainly not pathognomonic of the problem. While a deep, isolated, thin periodontal pocket is suggestive of VRF (83), difficulty aligning the periodontal probe along the periodontal defect sometimes means this sign is missed.…”

“…While a deep, isolated, thin periodontal pocket is suggestive of VRF (83), difficulty aligning the periodontal probe along the periodontal defect sometimes means this sign is missed. Radiographic features suggestive of VRF such as J-shaped and halo-shaped radiolucencies (83) do not appear until significant bone destruction has occurred and similarly shaped radiolucencies may manifest themselves in cases of apical periodontitis not associated with VRF.…”

Cone beam computed tomography (CBCT) is a contemporary, radiological imaging system designed specifically for use on the maxillofacial skeleton. The system overcomes many of the limitations of conventional radiography by producing undistorted, three-dimensional images of the area under examination. These properties make this form of imaging particularly suitable for use in endodontics. The clinician can obtain an enhanced appreciation of the anatomy being assessed, leading to an improvement in the detection of endodontic disease and resulting in more effective treatment planning. In addition, CBCT operates with a significantly lower effective radiation dose when compared with conventional computed tomography (CT). The purpose of this paper is to review the current literature relating to the limitations and potential applications of CBCT in endodontic practice.

“…One of the common radiographic findings in VRF is a "halo"-shaped radiolucency that may be seen as a periradicular rarefaction/ radiolucency on the lateral aspect of the affected root, which extends apically and to other sides of the root. 23 Computerized tomography was introduced Sir Godfrey Hounsfield in which images of thin slices of anatomy are captured and synthesized to obtain information in three dimensions. This was followed by the introduction of CBCT which was faster, with a lower radiation dose.…”

Cracks and fractures in teeth are difficult to diagnose and treat, especially in the initial stages. The etiology of cracks is still obscure. With an increase in both geriatric population and tooth retention, the incidence of cracked teeth can also increase. There are many types of cracks from simple craze lines to vertical root fracture. An astute clinician should make crack detection a part of diagnostic screening. Proper diagnosis and treatment of cracked teeth is not possible without knowledge of the types of cracks along with associated signs and symptoms. This review presents a brief introduction to the various types of cracks and will aid the clinician in crack identification and management.
