Schematic representation of the basic principles of MRI.aProtons are represented as red balls spinning around their own axis. When an external magnetic field B0(orange arrow) is applied, protons tend to align with the direction of B0and have only two possible orientation, spin-up, and spin-dow...
The maxillary bones of mice were scanned using micro-CT to calculate the bone volume/tissue volume (BV/TV) and bone mineral density (BMD) of the extraction socket. (E,F) An HE-stained histological section of the extraction socket is shown. The number of empty lacunae around the extraction...
c Short vertebrae from Tie2-Cre; Ai14 mice was imaged through the bone to reveal the inside vasculatures. Boxed area is enlarged in c’. d Tooth of Tie2-Cre; Ai14 was imaged after clearing to reveal the vascular network within the dental pulp. Boxed area is enlarged in d’. e ...
To the best of our knowledge, there have been no reports of methods to measure the amount of remnant pulp and apical tissue; however, this measurement might be achieved by visualizing tissue-deficient space in or around the root canal using micro-computed tomography (CT) scans with intracanal ...
DentCytoTool supported cell viability and promoted capillary-like network formation inside the pulp analogue. LPS induced expression of odontogenesis-related markers (RUNX2, ALP, DSPP) without compromising viability of the odontoblast-like cells, while co-treatment with LPS and resin monomers induced ...
In some embodiments, gas mixture is forced around the cone at a speed of at least 6,000 rpm. The pressurized gas and abrading powder mixture or a pressurized gas and liquid mixture under micro-tornado forces can be directed through a distal extended cannula toward the tooth structure. The ...
[...]progresses to a destructive extent in which the bacteria have already entered the pulp(thesoft tissuechamber inside the tooth) and infected the nerves may lead to an acute toothache or severe pain. hksh.com hksh.com 如牙齒因意外或受傷碎裂,或因嚴重蛀牙導致病菌深入牙髓(牙齒內的軟組織),...
In macroscopic appearance, we distinguish between spongy and compact bone in mature bone tissue. The compact (cortical or dense) bone forms the outer shell of each bone. It is formed by the osteons (Haversian systems)—cylindrical units formed by 4–20 lamellae around the central (Haversian) ...
The exosomes are directly dissolved in PBS or normal saline and injected into or around the target site. The advantage is that exosomes quickly reach the injured site to perform their functions and prevent clearance by the lung, liver and other tissues and organs. This simple method also prevent...
Despite the considerable advancements made in recent years, exemplified by the aforementioned examples, a significant obstacle persists in achieving successful osteogenesis. This challenge revolves around the need to ensure optimal delivery of oxygen and nutrients to the scaffold cells while effectively remov...
