“…2(b). The failure of restored teeth due to cracks of this type is a major obstacle to the success of restorative dentistry [14][15][16][17][18][19], and has been termed the "cracked tooth syndrome" [20]. Mechanical failures of restored teeth are likely to result from large stresses and/or fatigue, a cumulative process of damage development and The crack initiated at the interface of the restoration and tooth structure in the region where there is a large stress concentration (the encircled area).…”

Tooth fracture is a major concern in the field of restorative dentistry. However, knowledge of the causes for tooth fracture has developed from contributions that are largely based within the field of mechanics. The present manuscript presents a technical review of advances in understanding the fracture of teeth and the fatigue and fracture behavior of their hard tissues (i.e., dentin and enamel). The importance of evaluating the fracture resistance of these materials, and the role of applied mechanics in developing this knowledge will be reviewed. In addition, the complex microstructures of tooth tissues, their roles in resisting tooth fracture, and the importance of hydration and aging on the fracture resistance of tooth tissues will be discussed. Studies in this area are essential for increasing the success of current treatments in dentistry, as well as in facilitating the development of novel bio-inspired restorative materials for the future.

“…Coronal fractures of posterior teeth usually occur due to chronic masticatory trauma presence of large restorations or unrestored endodontically treated teeth [1, 2] and rarely due to acute trauma. If a visible separation occurs at the interface of segments along the line of fracture, such fractures are termed as “complete” as coined by Luebke [3].…”

Unlike anterior teeth, acute exogenous trauma is an infrequent cause of posterior coronal vertical tooth fractures. Endodontic and restorative management of such fractures is a great challenge for the clinician. Newer advancements in adhesive techniques can provide successful intracoronal splinting of such teeth to reinforce the remaining tooth structure. This paper describes the diagnosis and management of a case of complicated vertical coronal fracture in mandibular first molar induced by a traffic accident.

“…Periapical radiography is still the first method for obtaining an image in cases of suspected root fracture, as it is possible to view subtle alterations in the periodontal ligament space, periapical lesions, and bone resorption. 6 These radiographic images, however, are limited when it comes to detecting fractures, particularly vertical fractures, as the line of fracture can only be viewed when it is directly aligned with the X-ray beams, which is not true for the majority of cases. Moreover, the anatomical structures overlapping considerably reduce the examination's sensitivity as it is a two-dimensional (2D) image of three-dimensional (3D) structures.…”

Aim: Our objective was to perform an in vitro evaluation of root fracture in endodontically treated teeth using two cone beam computed tomography (CBCT) machines. Materials and methods:The sample comprised 86 singlerooted human premolars that had been fractured by a universal testing machine. The tomographic images were acquired using an Orthopantomograph OP300 ® and an Orthophos XG 3D ® and evaluated by three examiners, by means of specific software. The teeth were classified into presence or absence of root fracture, then the root third where the fracture occurred, was determined. With regard to the detection of the fracture, the Kappa statistic was used for intra and interexaminer reproducibility at two distinct points in time. Chi-squared test was employed to analyze the sensitivity and specificity of the two tomographs (p < 0.05). Results:The results showed a good or excellent Kappa index between examiners. As for the absolute frequency, the sensitivity (0.6) of the Orthophos XG 3D ® equipment was superior, while specificity (0.91) was higher with the Orthopantomograph OP300 ® . On the receiver operating characteristics curve, moderate performance was found with an accuracy of 0.73 (OrthopantomographOP300 ® ) and 0.74 (Orthophos XG 3D ® ) respectively. As far as the location of the root fracture is concerned, moderate agreement was verified using the Kappa statistic (k = 0.56). Evaluation of Root Fracture in endodontically treated Clinical significance:An early and precise detection of root fractures is of the utmost clinical importance, but the radiopaque and/or metallic filling materials in the CBCT viewing field may generate artifacts, known as the beam-hardening effect, which could compromise root fracture detection.
