Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

The Anatomical Record, EarlyView.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Conservative Management of Displaced Horizontal Root Fracture in Vital Maxillary Premolar: a Case Report

Balkan Journal of Dental Medicine, 2018
Background/Aim: The management of horizontal root fracture is not straight forward. It depends upon the location of the fracture, mobility and vitality of fractured tooth segment.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

The Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Dental fluorosis in the European roe deer (Capreolus capreolus): A review of the pathological changes in the enamel of fluorotic cheek teeth and the abnormal pattern of dental wear in affected dentitions

The Anatomical Record, EarlyView.
Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

Sharpening our understanding of saber‐tooth biomechanics

The Anatomical Record, EarlyView.
Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

Splinting of Longitudinal Fracture: An Innovative Approach

Case Reports in Dentistry, 2016
Trauma may result in craze lines on the enamel surface, one or more fractured cusps of posterior teeth, cracked tooth syndrome, splitting of posterior teeth, and vertical fracture of root.

Management of Cracked tooth syndrome: A case Report

Update Dental College Journal, 2014
Cracked tooth is a distinct type of longitudinal tooth fracture which occurs very commonly and its diagnosis can be challenging. This type of fracture tends to grow and change over time. Clinical diagnosis is difficult because the signs and symptoms are

Expert Perspective: How, When, and Why to Potentially Stop Antiresorptive Drugs in Osteoporosis

Arthritis &Rheumatology, EarlyView.
Osteoporosis is a chronic disease, and antiresorptive treatments are often continued for many years. Despite their established efficacy in reducing fracture risk, the most commonly used antiresorptive treatments, bisphosphonates and denosumab, have short‐ and long‐term risks that, coupled with their benefits and other unique characteristics, influence ...

Traumatic Dental Injury—An Enigma for Adolescents: A Series of Case Reports

Case Reports in Dentistry, 2012
Coronal fractures of permanent dentition are the most frequent type of dental injury. Fractured anterior teeth are usually treated with conventional post and core and crown techniques, after being treated endodontically. If the original tooth fragment is
