Orthodontically induced external apical root resorption in patients treated with fixed appliances vs removable aligners.

Angle Orthodontist, 2017
OBJECTIVE To determine whether orthodontic treatment with removable aligners vs fixed orthodontic appliances is associated with a different frequency of orthodontically induced external apical root resorption (OIEARR) when genetic, radiographic, and ...

Bilirubin Targeting WNK1 to Alleviate NLRP3‐Mediated Neuroinflammation

Advanced Science, EarlyView.
At physiological concentrations, bilirubin binds to the kinase domain of WNK1, thereby augmenting its activity and facilitating the phosphorylation of downstream SPAK/OSR1. This phosphorylation inhibits KCC2 activity, leading to elevate intracellular chloride levels in neurons.

Sharp Curvature of Premolar Resulting in External Apical Root Resorption of the Neighbouring Molar

Case Reports in Dentistry, 2011
This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second

A comparative evaluation of five obturation techniques in the management of simulated internal resorptive cavities: An ex vivo study

Journal of Pharmacy and Bioallied Sciences, 2019
Background: Root resorption is the loss of dental hard tissues as a result of clastic activities. It might be broadly classified into external or internal resorption by the location of the resorption in relation to the root surface.

Root resorption during orthodontic treatment with Invisalign®: a radiometric study

Progress in orthodontics, 2017
Root resorption (RR) is described as a permanent loss of tooth structure from the root apex. Many reports in the literature indicate that orthodontically treated patients are more likely to have severe apical root shortening, interesting mostly maxillary,

Human Bone‐Derived Endothelial Cells Mediate Bone Regeneration via Distinct Expression of KIT Ligand

Advanced Science, EarlyView.
Bone‐specific endothelial cells (b‐ECs) uniquely express KITLG, which recruits c‐Kit+/CD34+ hematopoietic progenitors (HPCs) to the osteovascular niche, initiating a cascade that culminates in the osteogenic differentiation of bone marrow‐derived mesenchymal stem cells (bm‐MSCs) and subsequent ossification.

Rootless existence: A case report of internal resorption

Journal of International Clinical Dental Research Organization, 2018
Internal resorption is a relatively rare resorption of dentine, which starts in the pulpal cavity either in the pulpal chamber or in the root canal and destroys surrounding dental hard tissues. The initiating factor in internal root resorption is thought

Internal root resorption

IP Indian Journal of Conservative and Endodontics, 2018
Root resorption is a process that leads to the loss of hard tissues of the tooth. It can either be physiologic or pathologic in origin. Depending on the site of the lesion it can be internal root resorption (IRR) or external root resorption (ERR). In this article internal root resorption is mainly focused.
