Basic Tooth Anatomy
Teeth are wrought according to its function and location in the mouth but regardless of its digit and function, it is be of the same structures as follows Crown- is the snarf portion of the tooth. This is what we can see in the oral cavity just by looking inside our patients mouth. Root- is the part of the tooth that is embed in the bone. We can see the offset of a tooth usually in a radiograph. Each tooth is composed of 4 uncomplicated structures namely Enamel- is the hardest and most mineralized substance in the body. It covers the outside of the crown of the tooth and is translucent.Because the content of beautify is highly mineralized it also makes it susceptible to cavities. How? Reasons for putrefaction vary but mostly it is collectable to ingestion of sugars that react with the bacteria make up in the mouth that forms a attribute of acid that attacks enamel therefore it weakens enamel and overtime causes cavities. Dentin- makes up the bulk of the tooth and lies u nder(a) enamel. It covers the pulp and the color may identify from gray to yellow usually come in through the enamel. Dentin is composed of mineralized link interweave like enamel but it is softer. It is necessary for the support of enamel.It also serves as a cushion to protect enamel from breaking. Pulp- is found at the center of the tooth. It is composed of nerves and blood vessels that provide nutrients to the tooth. And since it is make up of these structures, the pulp is soft and undefended without the protection of enamel and dentin. At the spinning top of the pulp we can find what is called as the apex of the root, this is a small scuttle where blood vessels and nerves pass through. Cementum- is a bone like connective tissue located around the root. It helps support the teething by providing a place of accompaniment to the other tissues that surround the teeth in the socket.
