Antagonistic interaction between Ezh2 and Arid1a coordinates root patterning and development via Cdkn2a in mouse molars

open access: yeseLife, 2019
Patterning is a critical step during organogenesis and is closely associated with the physiological function of organs. Tooth root shapes are finely tuned to provide precise occlusal support to facilitate the function of each tooth type.

Gear tooth root fatigue test monitoring with continuous acoustic emission: Advanced signal processing techniques for detection of incipient failure

open access: yes, 2018
The phenomenon of fatigue in gears at the tooth root can be a cause of catastrophic failure if not detected in time. Where traditional low-frequency vibration may help in detecting a well-developed crack or a completely failed tooth, a system for early ...

Construction of PANoptosis‐Inhibiting Carbonized Polymer Dots via Machine Learning Potential for Mitigating Chemodrug‐Induced Nephrotoxicity

open access: yesAdvanced Science, EarlyView.
An enhanced sampling method is developed for molecular dynamics based on trained machine learning force fields to guide the construction of PANoptosis‐inhibiting carbonized polymer dots (Lu‐CDs) derived from a flavonoid compound for treating chemodrug‐induced nephrotoxicity.

Possibilities of cone-beam computed tomography in the diagnosis of longitudinal fractures of the roots of teeth

open access: yesЭндодонтия Today, 2020
A vertical fracture of the tooth root, which is not diagnosed in time, may lead to periodontitis. On the other hand, if the root fracture is diagnosed, whereas in fact it is not, then the patient will remove the tooth on the basis of an error in the ...

Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears [PDF]

open access: yes
A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile

Induced Ankylosis of a Primary Molar for Skeletal Anchorage in the Mandible as Alternative to Mini-Implants [PDF]

open access: yes, 2015
Background Mesial protraction of mandibular posterior teeth requires increased anchorage to avoid undesired tooth movements. Orthodontic mini-implants have become a popular and successful way to increase skeletal anchorage in such cases.
