Tooth root resorption: A review. [PDF]

Sci Prog, 2022
Tooth root resorption is multifactorial, leading to progressive destruction and eventual loss of tooth root dentin and cement. There are internal and external types of root resorption, each having its variety. The etiology and pathogenesis of tooth root resorption are poorly understood, and the most significant etiological factors are trauma, pulpal ...

The Role of Wnt Signaling in Postnatal Tooth Root Development [PDF]

Frontiers in Dental Medicine, 2021
Appropriate tooth root formation and tooth eruption are critical for achieving and maintaining good oral health and quality of life. Tooth eruption is the process through which teeth emerge from their intraosseous position to their functional position in

Wnt-directed CXCL12-expressing apical papilla progenitor cells drive tooth root formation [PDF]

Nature Communications
The tooth root is a critical component of the tooth anchored to surrounding alveolar bones. Tooth root formation is driven by cells in the apical papilla (AP) that generate new dentin-forming odontoblasts at the root-forming front. Mesenchymal stem cells

A novel system for classifying tooth root phenotypes. [PDF]

PLoS One, 2021
Human root and canal number and morphology are highly variable, and internal root canal form and count does not necessarily co-vary directly with external morphology. While several typologies and classifications have been developed to address individual components of teeth, there is a need for a comprehensive system, that captures internal and external

Transparent dentin region in the tooth root. [PDF]

Clin Case Rep, 2020
AbstractTransparent dentin in the tooth root forms during the aging process. The transparent dentin is weaker than normal opaque dentin, which may explain the occurrence of root dentin fractures in aged individuals. Tooth fractures are caused by the brittleness of the transparent dentin.

Some historical musings on tooth/root resorption. [PDF]

J Istanb Univ Fac Dent, 2017
Contemporarily, the ravages of tooth resorption are seen daily around the world. While some teeth can be retained many are lost to this process. Although many types of resorptive processes have been identified, the etiological factors involved in this malady are not often clear and both speculation as to it source and clinical management have received ...

The Impact of the Eda Pathway on Tooth Root Development. [PDF]

J Dent Res, 2017
The Eda pathway ( Eda, Edar, Edaradd) plays an important role in tooth development, determining tooth number, crown shape, and enamel formation. Here we show that the Eda pathway also plays a key role in root development. Edar (the receptor) is expressed in Hertwig’s epithelial root sheath (HERS) during root development, with mutant mice showing a ...

BMP signaling in the development and regeneration of tooth roots: from mechanisms to applications

Frontiers in Cell and Developmental Biology, 2023
Short root anomaly (SRA), along with caries, periodontitis, and trauma, can cause tooth loss, affecting the physical and mental health of patients.

Dynamic Simulation of Cracked Spiral Bevel Gear Pair Considering Assembly Errors

Machines, 2022
The tooth root crack fault is a common fault type of the spiral bevel gear pair (SBGP). Affected by the strong bearing capacity, the early crack fault of the SBGP cannot be found in time.
