Frequency of root resorption following trauma to permanent teeth.
Journal of Oral Science, 2015 This retrospective study evaluated the frequency of development of root resorption in dental trauma cases involving supporting tissue. For 249 traumatized teeth of 125 patients aged between 7 and 51 years, we collected data on the gender and age of the ...

Advanced Materials, EarlyView.The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Remember the periroot sheet in orthodontic treatment of ectodermal dysplasia patients
Dental Hypotheses, 2014 Introduction: Root resorption has various etiologies. Recent studies have demonstrated a periroot sheet covering the root. The outermost layer of this sheet is the Malassez′ epithelial layer. Tooth malformations are seen in ectodermal dysplasia and it is

Cellular and molecular mediators of bone metastatic lesions [PDF]
, 2018 Bone is the preferential site of metastasis for breast and prostate tumor. Cancer cells establish a tight relationship with the host tissue, secreting factors that stimulate or inhibit bone cells, receiving signals generated from the bone remodeling ...

Tibial Implant Fixation in TKA Worth A Revision? -- How to Avoid Stress-Shielding Even for Stiff Metallic Implants [PDF]
arXiv, 2019 In total knee arthroplasty (TKA) force is transmitted into the tibia by a combined plate-stem device along with cemented or cementless stem fixation. The present work analyzes this force transmission in finite element simulations with the main aim to avoid reported postsurgical bone density reduction as a consequence of a reduced tibial bone loading ...

Vanishing roots: first case report of idiopathic multiple cervico-apical external root resorption.
Journal of clinical and diagnostic research : JCDR, 2015 Idiopathic root resorption is a very rare phenomenon. Resorption in tooth is brought about by odontoclastic activity. Special mechanisms in the periodontal ligament exist to prevent mineralization of the periodontal ligament and these periodontal ...
