Reduction of gear pair transmission error with tooth profile modification [PDF]
, 2008 The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...

Advances of exosomes in periodontitis treatment
Journal of Translational Medicine, 2022 Periodontitis is an inflammatory disease initiated by dysbiosis of the local microbial community. Periodontitis can result in destruction of tooth-supporting tissue; however, overactivation of the host immune response is the main reason for alveolar bone

Advances in tooth agenesis and tooth regeneration
Regenerative Therapy, 2023 The lack of treatment options for congenital (0.1%) and partial (10%) tooth anomalies highlights the need to develop innovative strategies. Over two decades of dedicated research have led to breakthroughs in the treatment of congenital and acquired tooth loss.

Dietary nitrate supplementation prevents radiotherapy-induced xerostomia
eLife, 2021 Management of salivary gland hypofunction caused by irradiation (IR) therapy for head and neck cancer remains lack of effective treatments. Salivary glands, especially the parotid gland, actively uptake dietary nitrate and secrete it into saliva.

Paleobiology: A Tooth for a Tooth [PDF]
Current Biology, 2017 Many vertebrates replace teeth through shedding of the functional tooth. New analyses of a fossil fish demonstrate that shedding involved tooth resorption, a primitive feature in bony fishes, but absent in sharks and their relatives.
