— A series of 468 teeth with root fractures, mainly caused by corrosion of root canal pins and/or posts, was evaluated to determine the clinical and radiographic criteria which may be used in diagnosing these fractures. The fractures could be seen directly in a radiograph in only one-third of the cases. Indirectly, evidence of a fracture could be demonstrated radiographically by the presence of corrosion products from the pin or post or by dissolution of the pin in 71.8 % of the cases. Marginal pocket formation, a widening, or blurring of the periodontal space was observed in 79.8% of the cases. In 53.8 % an apical radiolucency was present, whereas 10 cases (2.7 %) showed no radio-graphic signs. The findings emphasize the importance of always considering the possibility of a root fracture when dealing with teeth containing pins, posts, and crowns.read more

TL;DR: The results showed that non-vital teeth had mean pain threshold levels that, on cantilever loading, were more than twice as high as those of their neighboring or contralateral vital teeth.

Comparison of Five Cone Beam Computed Tomography Systems for the Detection of Vertical Root Fractures
TL;DR: This study compared the accuracy of cone beam computed tomography scans made by five different systems in detecting vertical root fractures (VRFs) and assessed the influence of the presence of root canal filling, CBCT slice orientation selection, and the type of tooth (premolar/molar) on detection accuracy.

TL;DR: The importance of the correct diagnosis of VRF is emphasized, the more typical clinical and radiographic features of this disorder are described, and its prevalence and multifactorial etiology are summarized.
