Orthodontic tooth movement: The biology and clinical implications

Kaohsiung Journal of Medical Sciences, 2018
Orthodontic tooth movement relies on coordinated tissue resorption and formation in the surrounding bone and periodontal ligament. Tooth loading causes local hypoxia and fluid flow, initiating an aseptic inflammatory cascade culminating in osteoclast ...

Evaluation of the Accuracy of Different Apex Locaters with 45° Apical Root Resorption

Dentistry 3000
Aim: This study was aimed to calculate the working length (WL) of permanent teeth with simulated 45° resorption of the apical part of the root using four electric apex locaters (EALs): NSK, Woodpecker III, Woodpecker V, and Eighteeth.

Is relevant the underestimation of irregular apical root resorption by periapical radiographs?

HU Revista, 2019
Introduction: Periodic control of root resorption during orthodontic treatment is frequently made by two-dimensional radiographic examinations, in which irregular resorptions are not detected buccolingually.

Multiscale modelling couples patches of two-layer thin fluid flow [PDF]

arXiv, 2014
The multiscale gap-tooth scheme uses a given microscale simulator of complicated physical processes to enable macroscale simulations by computing only only small sparse patches. This article develops the gap-tooth scheme to the case of nonlinear microscale simulations of thin fluid flow.

The various forms of tooth resorption

Australian Endodontic Journal
AbstractTooth resorption refers to the loss of the organic and inorganic components of tooth structure by clastic cells. The complex and multifaceted nature of its aetiology, along with the several classification schemes published in the area, are likely to create confusion amongst researchers and clinicians, and may lead to compromised treatment ...

Osteocytes and mechanical loading: The Wnt connection [PDF]

, 2019
Bone adapts to the mechanical forces that it experiences. Orthodontic tooth movement harnesses the cell‐ and tissue‐level properties of mechanotransduction to achieve alignment and reorganization of the dentition.

Salivary advanced glycated end products, their receptors, and aMMP‐8 in periodontitis patients with varying glycemic levels: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background Advanced glycation end products (AGE) and their receptors (RAGE) have been implicated in developing periodontal complications in diabetic patients. This study aimed to identify salivary AGE, RAGE, soluble RAGE (sRAGE), and active‐matrix metalloproteinase‐8 (aMMP‐8) levels at varying glycemic levels in periodontitis patients ...

Effect of Tramadol (μ-opioid receptor agonist) on orthodontic tooth movements in a rat model.

Frontiers in Dentistry, 2012
Tramadol is a synthetic analgesic of opioids which has more flexible mechanisms of action than typical opioids. Since it has been reported in previous study that typical opioids like morphine can affect the bone homeostasis, it is worthwhile to examine ...

Effects of FGF on tooth movement and root resorption

Journal of Craniomaxillofacial Research, 2022
Introduction: Basic fibroblast growth factor (bFGF) is an effective cytokine in angiogenesis and bone remodeling. The aim of this study was to determine the effect of locally injected bFGF on movement rate and root resorption during orthodontic force ...
