The term cracks was used to describe the narrow, fissure-like structures that are seen on almost all surfaces.
They are actually the outer edges of lamellae.
In decalcification of ground sections of enamel,cracks usually disappear whereas the enamel lamellae still persist because they contain greater concentrations of organic material.
Enamel lamellae are thin, vertical defects within the enamel that do not penetrate through the entire enamel layer, while enamel cracks are more extensive fractures that can extend deeper into the enamel. Enamel lamellae are usually more superficial and may not compromise the integrity of the tooth, whereas enamel cracks can weaken the tooth structure and may require treatment.

What is the difference between enamel lamella and crack?
Enamel lamellae are defects in tooth enamel that result from incomplete mineralization, while cracks in enamel are actual fractures in the enamel surface that can extend into deeper layers. Enamel lamellae are usually superficial and do not necessarily compromise the structural integrity of the tooth, whereas cracks can weaken the enamel and potentially lead to tooth sensitivity or decay.
What is hypocalcified and hypercalcified structure of dentin?
Hypocalcified dentin refers to dentin that has not been fully mineralized, leading to reduced hardness and strength. Hypercalcified dentin, on the other hand, refers to dentin with excessive mineralization, which can make it appear darker in color and more resistant to decay.
Is enamel stronger or hair?
Enamel is stronger than hair. Enamel is the hardest substance in the human body, providing protection to the teeth from wear and decay. Hair is made of keratin, a protein that is not as hard as enamel.
What are advantages BONDING?
Bonding can improve the aesthetics of teeth by repairing chips, cracks, and discoloration. It is a quick and relatively inexpensive procedure compared to other cosmetic options. Bonding is also minimally invasive, as it usually does not require the removal of tooth enamel.
How do you use enamel in a sentence?
I need to get my enamel pots and pans re-coated because the surface is starting to chip.

What is the difference between enamel lamellae and tufts and spindles?
Enamel lamellae extend from the Dentino-Enamel Junction to the outer surface. Tufts are projections from the Dentino-Enamel Junction for a short distance due to the changes of enamel rods arising from the scalloped junction.
Hypocalcified structures of dentin?
Enamel tufts Enamel spindles Enamel lamellae Striae of Retzius Neonatal lines
Difference between plastic emulsion and enamel paint?
emulsion paint: paint in which the binder is dispersed in water. enamel paint: pigmented varnish, glossy coating
What is the difference between Teeth and gizzard.?
Teeth are made of hard bone and enamel. The gizzard is a muscular structure.
What is the difference between satin enamel and satin paint?
No because it looks like the same color sort of. Also it like a litte lighter but you barely can tell .There is technically no difference. That is your answer,Thank you

What is found just below the enamel of a tooth?
Below the enamel is the dentin or dentine you can call it one of those two it duznt matter and the dentin/dentine is between the cement and enamel.(below the enamel , on top of the cement.)
What is the difference between Moriage and Coralene?
Coralene decoration is miniscule glass balls applied on glass. Moriage, popular on Japanese ceramics, is an applied enamel decoration, think of decorating a cake.
What is the difference between cast iron and steel enamel (from the perspective of enamel frit)?
To understand the difference between cast iron enamel and steel plate enamel, we must first know the difference between cast iron and steel plate. Both steel and cast iron are iron-carbon alloys, and the distinction between these two metallic materials is mainly based on carbon content. The cast iron generally used in enamel is gray iron or gray cast iron, and the carbon content is usually 3%~3.7%, while the carbon content of refined iron (low carbon steel cold-rolled sheet) is less than 0.12%, which means that cast iron contains more than steel plate. More impurities, when sintering, are more likely to generate carbon dioxide and other gases, resulting in enamel defects such as pinholes, air bubbles, and pores on the porcelain surface. Therefore, in the selection of enamel frit, cast iron enamel frit needs to meet the following conditions: low temperature firing, to avoid oxidation and decomposition of iron carbide in cast iron, and release carbon dioxide; good adaptability, which is conducive to gas in the early stage of firing It has good sealing performance, and does not allow gas to break through the porcelain layer and cause defects in the later stage of firing. Therefore, the formula design of enamel primer is very different from that of steel plate primer. For example, the firing temperature is generally 760~780℃, which is obviously lower than the high temperature of 850℃ of steel plate primer. At the same time, the addition amount of cast iron frit in borax, feldspar and other raw materials is larger than that of steel plate enamel frit, the purpose is to reduce the viscosity of the enamel frit, improve the wettability, form small pores and accommodate the gas discharged from the matrix, and improve the solubility of iron oxide. The formula design of cast iron enamel frit and steel plate enamel frit is very different, in order to meet the needs of enamel enamel frit for the corresponding material to the greatest extent.
What is the difference between nail polish and nail enamel?
The difference is nail polish, is basicly nail paint....But nail varnish is like the special nail paint they use to make designs on your nails. - - - - - Nail polish, nail varnish, nail paint and nail lacquer are four names for the same stuff. It just comes down to what the manufacturer wants to call it.
What is the difference between enamel insulated wire and paper insulated wire?
Paper insulated wire is coated with DuPont's NOMEX Paper wrap which can withstand temperature over 200 degrees centigrate. Enamel insulation usually is coated over aluminum wire and shipped from 3rd world countries to put in our houses because housing contractors don't care if your house burns down. bottom line is money, enamel is cheaper.
