What is another name for the cervical line of a tooth?
Another name for the cervical line of a tooth is the cementoenamel junction (CEJ). This is the area where the enamel of the crown meets the cementum of the root. It is an important landmark in dentistry for assessing periodontal health and tooth structure.
Where is the cementoenamel junction located?
The cementoenamel junction (CEJ) is the area in the tooth where the enamel of the crown meets the cementum covering the root. It is typically located at the gum line and serves as an important landmark for dental anatomy. The CEJ can vary in its position among different teeth and individuals, influencing the overall health and appearance of the tooth.
How do you locate cemento enamel junction in cervical abrasion?
To locate the cemento-enamel junction (CEJ) in cases of cervical abrasion, visually inspect the tooth for the transition line between the enamel and cementum, which is typically found at the gingival margin. You can use a periodontal probe to gently explore the area, as the CEJ is often slightly rougher than the surrounding enamel. Additionally, applying a disclosing solution can help highlight the junction by staining the exposed cementum differently from the enamel. Accurate identification is crucial for proper diagnosis and treatment of cervical abrasions.
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.
What is the soft decayed area in a tooth?
The soft decayed area in a tooth is known as dental caries or a cavity. It occurs when bacteria in the mouth produce acids that erode the tooth's enamel, leading to the breakdown of the underlying dentin. This decay can result in pain, sensitivity, and if left untreated, may progress to more severe dental issues such as infection or tooth loss. Regular dental check-ups and proper oral hygiene can help prevent the development of cavities.
What is a whole in a tooth?
A hole in a tooth, commonly referred to as a cavity, is a decayed area that forms when acid produced by bacteria in plaque erodes the tooth enamel. This process often results from poor oral hygiene, leading to tooth decay. If left untreated, cavities can progress deeper into the tooth, potentially causing pain and infection. Regular dental check-ups and good oral hygiene practices can help prevent cavities.
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.
