Fracture Resistance of CAD/CAM Lithium Disilicate of Endodontically Treated Mandibular Damaged Molars Based on Different Preparation Designs

International Journal of Biomaterials, 2019
The aim of this study was to evaluate the fracture resistance of 2 different types of all-ceramic crown using immediate dentin sealing (IDS), obtained using a CAD/CAM system on molars with different preparations.

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Management of Horizontal and Multiple Crown-Root Fractures

World Journal of Dentistry, 2011
ABSTRACTTraumatic injury to oral cavity with accompanying tooth fracture can be a tragic experience for the patient and is a problem that requires experience, judgment and skill of the dentist. The dental health and appearance marred by an unsightly injury must be restored to normal as soon as possible.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Effect of a ferrule and increased clinical crown length on the In Vitro fracture resistance of premolars restored using two dowel-and-core systems

, 2007
This study investigated the effect of a crown-lengthening ferrule on the fracture resistance of endodontically-treated teeth restored with two dowel-core systems.

The lower deciduous dentition of protodidelphids (Mammalia, Marsupialia) from the Itaboraí Basin (lower Eocene), Brazil, and the validity of “Riolestes capricornicus” (Goin et al., 2009)

The Anatomical Record, EarlyView.
Abstract The Itaboraí Basin, Southeastern Brazil, preserved one of the most diverse mammalian faunas from the Paleogene, with Metatheria comprising more than 60% of its diversity. Among identified metatherian clades, it has been argued that Paucituberculata is represented by “Riolestes capricornicus”.

Treatment of crown-root fracture with a modified crown fragment reattachment technique [PDF]

, 2010
The development of adhesive dentistry has allowed that the crown fragment reattachment can be another option in the treatment of crown fracture. However, additional crown lengthening procedure or extrusion of the tooth may be necessary in the treatment ...

Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...
