— 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: This study describes 11 Chinese patients with 12 molars that developed vertical root fractures without endodontic or post procedures that showed characteristics of a true vertical root fracture as confirmed after extraction.

Longitudinal tooth fractures: findings that contribute to complex endodontic diagnoses
Eric M. Rivera,Richard E. Walton +1 more
TL;DR: The purpose of this review is to describe and discuss the diagnostic and treatment challenges related to tooth fractures primarily in the vertical plane, that is, the long axis of the crown and/or root, to provide global definitions that researchers and clinicians can use to eliminate confusion.

In vitro evaluation of the fracture resistance of anterior endodontically treated teeth restored with glass fiber and zircon posts
TL;DR: Within the limitations of this study, the teeth restored with glass fiber and zircon posts demonstrated significantly lower failure loads than those with cast NiCr post and cores.

Three-dimensional, non-destructive visualization of vertical root fractures using flat panel volume detector computer tomography: an ex vivo in vitro case report.
TL;DR: The FD-VCT is an innovative diagnostic tool for non-destructive, three-dimensional evaluation of extracted teeth in pre-clinical and experimental studies and allows precise visualization and evaluation of vertical root fractures or cracks in extracted teeth.
