Crown Ethers

Crown ethers are cyclic polyethers that contain multiple oxygen atoms, usually arranged in a regular pattern. The first crown ether was synthesized by Charles Pederson while working at DuPont in 1967. For this work, Pedersen was co-awarded the 1987 Nobel Prize in Chemistry. Crown ethers are named using the formula x-crown-y, where x is the total number of atoms in the ring and y is the number of ether oxygen atoms. The term 'crown' refers to the crown-like shape that these ether molecules take.

This video demonstrates the utilization of a microfluidic device to study the interactions between tooth germ pulp and trigeminal ganglia. It showcases the placement of tissues inside the microfluidic device and provides a detailed visualization of trigeminal neurite growth toward the tooth germ through the device's microgrooves. Additionally, it highlights the role of tooth-derived molecular factors in promoting or inhibiting neurite extension into the tooth germ pulp, which is crucial for...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth. The Crown, Neck, and Root The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Co-cultures represent a valuable method to study the interactions between nerves and target tissues and organs. Microfluidic systems allow co-culturing ganglia and whole developing organs or tissues in different culture media, thus representing a valuable tool for the in vitro study of the crosstalk between neurons and their targets.

The crown region of different V3 loop sequences of the surface envelope glycoprotein (gp120) of HIV-1 can be structurally characterized in many cases by in silico folding of positions 10 to 22 of the loop using a state-of-the-art ab initio folding algorithm. Here we demonstrate the folding and evaluation of this region of the V3 loop from the R2 strain of HIV-1, a uniquely neutralization sensitive strain with puzzling functional properties.
FAQs
Enamel’s densely packed hydroxyapatite crystals provide the tooth crown with resistance to mechanical wear. Because this mineralized layer forms the outer surface, it bears forces generated during biting, cutting, and grinding before those forces reach deeper tissues. Studying crystal density and surface wear helps biology and dental research examine how crown structure supports repeated food-processing functions.
Dentin acts as a mechanical transition layer beneath enamel. Rather than leaving the outer tissue to handle forces alone, it absorbs and distributes loads through the crown, helping explain how the tissues work together during chewing. This relationship is important when researchers evaluate wear, structural damage, or restorative treatments intended to recover normal function.
The pulp links crown structure to both tooth vitality and sensation. Its blood vessels support living tissue, while its nerves transmit sensory signals when conditions affect the tooth. Consequently, crown research must consider more than external hardness: changes or treatments involving enamel and dentin can be evaluated in relation to the protected internal pulp.
Tooth crown studies can follow how its tissues relate to development, enamel erosion, dental caries, and restorative treatment. The crown provides a shared structural framework for comparing these topics: researchers can examine the protective outer layer, the force-bearing dentin beneath it, and the vital pulp within. This broad view connects normal biology with changes affecting function and protection.
When evaluating a restorative treatment, researchers can ask whether it restores crown function while protecting the tissues beneath enamel and dentin. Relevant outcomes include recovered biting, cutting, or grinding performance and preservation of the internal pulp. Thus, crown structure supplies criteria for judging whether treatment addresses both mechanical demands and tooth vitality.
Its layered organization lets researchers relate changes at the exposed enamel surface to deeper dentin and pulp, whose mechanical and biological roles differ. This perspective supports investigations of enamel erosion and dental caries while accounting for the entire crown rather than an isolated surface. It also helps connect structural observations with the tooth’s function, sensation, and vitality.
