What are the names of the sections of the tooth?
The main sections of a tooth are the crown, neck, and root. The crown is the visible part above the gum line, the neck is the area where the crown meets the root, and the root anchors the tooth into the jawbone. Additionally, the tooth contains layers such as enamel, dentin, and pulp, which play crucial roles in its structure and function.
Why is dentinoenamel- junction most sensitive part in the tooth?
The dentinoenamel junction is the area where the hard enamel on the outside of the tooth meets the softer dentin on the inside. This junction is more sensitive because it lacks the protective enamel layer that covers the rest of the tooth, making it more susceptible to external stimuli like temperature changes and acids that can cause sensitivity and pain.
What area of the mouth is the apex located?
The apex of a tooth is the tip of the root where nerve and blood supply enter the tooth through the root canal. It is located at the bottom of the tooth, in the area where the tooth meets the jawbone.
What do you do when a filling falls out?
Enamel is what protects the tooth, when your tooth needs a filling, it is because that enamel is no longer in that area. As you have no enamel where your filling was, it is highly likely that the hole will get bigger. It's much better to get it filled again to prevent further problems.
How is a molar tooth adapted?
A molar tooth is adapted for grinding and crushing food due to its broad, flat surface with ridges called cusps. This shape helps increase the surface area for better food breakdown. The strong enamel covering protects the tooth from wear and tear during chewing.
What is the use of fluoride toothpaste?
Fluoride ions in small amounts strengthen the surface of tooth enamel, hydroxyapatite. In an area where drinking water contains no natural traces of fluoride people get more caries and need more fillings. In some countries fluoride is added to drinking water.
Do dogs have an enamel?
The thickness of the enamel of dogs was measured in the teeth of the animal. The enamel was found to be thinner than that of human teeth, varying in thickness from 0.1mm-1mm. The "enamel bulge" coronal to the cemento-enamel junction does not consist of a thickened area of enamel.
How can you paint a mural with acrylic paint on a background done in flat enamel without sanding over the background that is staying?
Any flat paint (even enamel) will provide plenty of tooth for acrylics. As long as the mural is not going in a high traffic area (where it will be touched often and eventually need cleaning) it should be fine.
The soft area of the tooth contains what?
the soft area of the tooth contain the pulp
What are the long term effects of etching the teeth in preparation for sealant application?
There are no long term effects of etching the teeth before sealant application. The etchant is a strong acid that dissolves the matrix material between the enamel rods that make up the tooth. It is rinsed off within seconds and leaves the tooth with a frosty appearance when dried. The nature of a resin dental sealant is that it requires a mechanical bond with the tooth, this mechanical bond is achieved between the sealant material and the enamel rods. In the case the tooth was "over etched" that is to say the sealant material is not covering the entire etched surface of the tooth, the minerals in the saliva, and topical fluoride rebuild that area of the tooth to make it as sound as it was before the procedure.

What is dental erosion?
Dental erosion is a permanent loss of all or part of a tooth due to the gradual chemical breakdown of the teeth. This breakdown is triggered by the introduction of some type of acid to the surface of the tooth. When regular dental hygiene is not practiced, the acid gradually wears away at first the Enamel (the outer layer of tooth) coating the exterior of the tooth, then advances to begin breaking down the dentin that makes up the main body of the tooth. Unlike many health issues, dental erosion cannot be reversed. The only solutions are to halt the erosion and use modern techniques to rebuild the damaged area of the tooth, or to replace the tooth altogether.
Can you paint enamel over latex?
Enamel is a word used to describe a finish, not the formulation of a paint. It simply means a hard reflective surface. Many people mistakenly use the word enamel when referring to oil based paints. So. if you are asking if you can paint latex or acrylic paint over a latex or acrylic enamel the answer is yes, however, I strongly recommend you sand the old paint first to give the top coat "tooth". If you are asking about painting latex or acrylic over an oil based paint the answer is still yes, however you must first sand the old paint and apply a good quality primer to it. Check with a reputable paint retailer for the best brand in your area.
