Parenting: Roots of the sweet tooth

Science, 2014
In her news story “The taste of things to come” (special section on Parenting, 15 August, p. [750][1]), E. Underwood discussed the flavor learning that happens during specific periods in the womb.

Geometrical complexity and crack trajectory based fatigue life prediction for a spur gear having tooth root crack

Engineering Failure Analysis, 2019
The objective of the present study is to perform a three-dimensional crack propagation path analysis for different geometrical parameters of spur gear tooth and study its implications on fatigue life of gear.

A model approach for considering nonmetallic inclusions in the calculation of the local tooth root load-carrying capacity of high-strength gears made of high-quality steels

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019
Demands for higher performance have caused a need for improved component characteristics, e.g. through surface strengthening of gears and increased cleanliness of gear steels. Unfortunately, a resultant drawback is that cracks in such high-strength gears

A new analytical model to calculate the maximum tooth root stress and critical section location of spur gear

Mechanism and Machine Theory, 2018
An accurate calculation of the maximum tooth root stress (TRS) and critical section location (CSL) provides a basis for predicting and improving gear performance.

A three-dimensional analysis of tooth-root morphology in living bears and implications for feeding behaviour in the extinct cave bear

Historical Biology, 2018
The morphology of both crowns and tooth-roots reflects dietary specialisation in mammalian carnivores. In this article, we analyse the tooth-root morphology of maxillary teeth from CT scans of living bears (Ursus arctos, Ursus americanus, Ursus maritimus,

Bone resorption deficiency affects tooth root development in RANKL mutant mice due to attenuated IGF-1 signaling in radicular odontoblasts.

Bone, 2017
The tooth root is essential for normal tooth physiological function. Studies on mice with mutations or targeted gene deletions revealed that osteoclasts (OCs) play an important role in tooth root development.

Root intrusion in tooth-implant combination cases

Implant Dentistry, 1993
The various proposed etiologies for root intrusion in tooth-implant combination cases are discussed. Clinical examples of root intrusion are illustrated. Advantages and disadvantages of nonrigid connector and coping/suprastructure techniques are presented.
