Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

A Summary of the Research on the Effect of Gear Tooth Root Strengthening on Bending Fatigue Strength based on Residual Stress

open access: yesJixie chuandong, 2019
With the continuous development of engineering technology, bending fatiguestrength has become an important limiting factor for the further development of gears, and bending fatigue failure is more dangerous than tooth surface failure.

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

open access: yesThe 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.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

THE DETERMINNATION OF RESIDUAL STRESS OF GEAR TOOTH ROOT BASED ON X-RAY TECHNOLOGY

open access: yesJixie qiangdu, 2017
Transverse residual stress of tooth root has significant influence on bending fatigue strength of gears.But given the geometry of gears,using the method of exposing teeth root to complete determination of transverse residual stress at present,it not only

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

open access: yesThe Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Orthodontic management of severe inversely impacted maxillary central incisors: a case series

open access: yesFrontiers in Oral Health
BackgroundAbnormal positioning and dislocation of the central incisor can disturb tooth eruption. Generally, inversely impacted maxillary central incisors do not erupt naturally.
