Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Prevalence of pulp stones in a Saudi Arabian subpopulation: A cone-beam computed tomography study

Saudi Endodontic Journal, 2018
Objective: To determine the prevalence of pulp stones using cone-beam computed tomography (CBCT) and to explore any potential correlation between the occurrence of pulp stones with age, gender, tooth, arch, and tooth status.

Remineralization strategies in oral hygiene: a position paper of Italian Society of Oral Hygiene Sciences-S.I.S.I.O. working group [PDF]

, 2017
Background/Objective: The clinical conditions that lead to an alteration of the enamel structure are numerous. The diet high in sugars and acidifying substances, psychological stress that triggers parafunctional behaviors, the reduced intake of fiber ...

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

The Effect of Exosomes Derived from Human Umbilical Cord Mesenchymal Stromal/Stem Cells on the Regeneration of Human Pulpectomized Tooth: A Case Report [PDF]

Iranian Journal of Medical Sciences
The dental pulp is essential for tooth health and sensory function. However, conventional treatments for infected or necrotic pulp, such as root canal therapy, frequently result in tooth loss and increased fracture risk.

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Stress behaviour across human tooth by temperature gradient resulting of laser irradiation

Journal of Mechanical Engineering and Sciences, 2020
The authors report the simulation of temperature distribution and thermally induced stress in the premolar tooth under ND-YAG pulsed laser beam. The Three-Phase-Lag (TPL) non-Fourier model is proposed to describe the heat conduction in the human tooth ...

Quantification of Neural Protein in Extirpated Tooth Pulp [PDF]

Journal of Endodontics, 2008
Because the pulp tissue extirpated during root canal procedures might serve as a valuable resource with which to assess underlying mechanisms of persistent pain, we sought to determine whether standard Western blotting techniques could be used to quantify neural proteins in pulp extirpated from teeth with irreversible pulpitis.

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.
