Tooth fractures in the Krapina Neandertals
Journal of Human Evolution, 2018Dental fractures can be produced during life or post-mortem. Ante-mortem chipping may be indicative of different uses of the dentition in masticatory and non-masticatory activities related to variable diets and behaviors. The Krapina collection (Croatia, 130,000 years BP), thanks to the large number of teeth (293 teeth and tooth fragments) within it ...

Fracture resistance of simulated immature tooth roots reinforced with MTA or restorative materials.
Dental Traumatology, 2016BACKGROUND/AIM Immature endodontically treated teeth may require reinforcing to reduce the risk of root fracture. This study assessed the fracture resistance of simulated immature tooth roots reinforced with mineral trioxide aggregate (MTA) or two ...

Diagnostic of tooth fractures with the Vistascan system
Dental Traumatology, 2008Abstract – Compared with conventional films digital radiography allows a wide range of exposure and scanner settings. The aim of this study was to investigate the diagnostic accuracy of the evaluation of tooth fractures depending on variations of exposure dose, scanner settings and surrounding tissues. Extracted human teeth were exposed separately and

Tooth fracture in vivo and in vitro
Journal of Dentistry, 1992The incidence, causes and methods of investigating tooth fracture are reviewed. This is a problem of increasing clinical significance, with many predisposing factors. Large restorations and extensive carious lesions tend to be associated with most fractures, with fracture incidence being higher in first permanent molars than other tooth types ...

Repair technique for a fractured crowned tooth
The Journal of Prosthetic Dentistry, 1977A simple technique is presented in which an existing crown can be replaced on a broken endodontically treated tooth in one appointment. This can reduce the working time and expense required for a new crown.

Restoration of a fractured anterior tooth
The Journal of the American Dental Association, 1978A fragment of tooth missing for three years was found in the patients' lower lip. The fragment was surgically removed and cleaned. It was restored to its original position on the maxillary left incisor with an acid etch resin technique. After three months, the restoration was satisfactory.
