Diatom‐Inspired 1D Immobile Robots Capable of 2D Collective Mobility

Advanced Intelligent Systems, EarlyView.
This study presents a diatom‐inspired robotic system that explores group coordination through limited physical interactions. The researchers tune groups of Barbots, simple robotic agents that possess neither individual mobility nor explicit communication capabilities, to achieve complex and adaptive collaboration based on environmental light.

Short dental implants in the posterior region : the effect of platform-switching and a nanorough surface on peri-implant bone loss [PDF]

, 2012
Korte implantaten (10 mm lengte), waarvoor meerdere redenen bestaan. In de eerste plaats heeft een kort implantaat minder oppervlak beschikbaar voor contact tussen bot en implantaat dan een langer implantaat met eenzelfde diameter.

Monoallelic POLR3A Variants Cause Early‐Onset Peripheral Neuropathy

Annals of Neurology, EarlyView.
Objective Biallelic variants in genes encoding the RNA polymerase III complex (Pol III) cause a spectrum of neurological disorders primarily affecting the central nervous system. Monoallelic variants have been reported in the POLR3B subunit only, associated with neurodevelopmental disorder, epilepsy, and peripheral neuropathy.

Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

Advanced NanoBiomed Research, EarlyView.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity

Tooth surface mismatch design of cycloidal bevel gear based on two directions modification of pinion cutter

Journal of Advanced Mechanical Design, Systems, and Manufacturing
Aiming at the sensitivity of installation errors caused by the complete conjugated tooth surface of cycloidal bevel gear, a method of tooth surface mismatch design which only modified the pinion cutter along two directions was proposed.

Effect of Approximal Tooth Surface Morphology on the Formation of Overhang Filling of 2nd Class [PDF]

, 2006
A relationship between approximal tooth surface morphology and creation of overhang filling is displayed. After drilling of approximal cavity, the gingival cavity margin was evaluated as concave or non-concave.

Bacterial Populations of Selected Tooth Surface Sites [PDF]

, 1969
The bacteriologic profile of selected tooth surface sites was determined by using culture procedures. Although there were differences in the percentage distribution of bacteria on the tooth surface of the lower anterior, upper premolar, and molar ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Tooth Surface-Finishing and Tooth Surface Texture of Case-Carburized Gears : An Application of Tooth Surface-Finishing Methods by Using Volcanic-Ashes [PDF]

, 2013
In order to develop the economical and environmental manufacturing processes and to obtain the high load-carrying capacity of case-carburized gears, the tooth surface-finishing method using the volcanic-ashes was studied. In this paper, the tooth surface

Tooth-like structures in a historical skull confirm the odontogenic potential of the vestibular epithelium. [PDF]

, 2016
During rescue archaeological research in 2007 and 2008 at the Gan locality (Galanta district, Slovak Republic, the Migration Period, 5th - 6th c. AD), three tooth-like structures were found in a female skull excavated from grave AH19 (A-F).
