CHAPTER II: REVIEW OF RELATED LITERATURE Teeth A tooth is a small, white structure found in the jaws or mouths of many vertebrates and used to break down food. Teeth are modified to get food more efficiently and to extract nutrients faster and more thoroughly from food. Teeth are used by every human to chew food for digestion. Human teeth are made up of two primary parts: the crown and the root. The crown is the portion of the tooth above the gums while the root is the part that anchors the tooth to the bone. Human teeth also compose of enamel and dentine that makes the teeth harder and less prone to tooth decay. Different mammals have very similar teeth. Due to teeth variation because of different food that different mammals eat, pig teeth can be a very good model for studying development of human teeth because they are mammalian omnivores. Like humans, pigs are diphyodant or develop and erupt two different generations of teeth in their mouths. Pig and human teeth also have outer coating of enamel, which is the hardest tissue in the human body. Dental Erosion Dental erosion is the gradual loss of normally hard surface of the tooth due to chemical and not the bacterial, processes. Erosion shows up hallow parts of the teeth and a general wearing away of the surface of the tooth. This can expose dentin underneath the enamel. Because …show more content…
When the enamel is softer, this can lead to plaque formation. Plaque formation can result in enamel erosion. If destruction from phosphoric acid becomes severe, erosion may spread under your enamel and into the layer of dentin below which causes sensitivity and toothaches. Citric acid is a natural, weak organic acid that is found in many fruits and vegetables, especially citrus (Moncel, n.d.). It is a natural preservative or conservative that is used to add an acidic or sour taste to foods and

The entire order of carnivores is defined by four teeth called carnassials. If you have those kind of teeth, you are a member of the carnivore family, if you don’t have those teeth, you can’t be in that family. The earliest teeth in the fossil record come from Conodonts. There is evidence that teeth were the first hard part ever. Niels next topic is about heads.
It is difficult to determine if tooth loss was a result of either advancing age or pathology. However, due to substantial bone resorption (bone loss) of both the mandible and maxilla, tooth loss occurred years before death. It is hypothesized that this individual either was able
For humans, the tooth shape reflects based on how we consume in our diet quality. The majority of humans in today’s generation consume meat, which molds our molars to be a lot smaller opposed to the other primates. The diet quality of fossil hominins is relevant to the shape of their tooth, in which certain kinds of their species that have consumed fruits
From the fossil teeth, we can infer that insects were not the only food for early primates, they also eat fruits as there are the presence of round molars which facilitate grinding. For instance, from the features of lions, we can see that they eat both meats and plats. In their teeth, there are both flat sharp molars. The flatter and rounder molars are for grinding grass fruits while sharper molars are for tearing meats. Also, by observing human fossil teeth, the flat and round molars enable them to grind plants and fruits.
It is common knowledge that creatures with pointed teeth
The aim of the experiment was to test different types of soft drink on calcium carbonate marble chips, which were used in place of human teeth, and record what percentage of the marble chips dissolved when it was left in the soft drink overnight. These results will show which of the five soft drinks tested was the most harmful, and the ingredients will be examined to explain why the particular soft drink was the most detrimental to human teeth. Human teeth are covered in a hard substance called tooth enamel, which is made of hydroxyapatite. Enamel is the hardest tissue in the body and is vital in protecting teeth from decay (Callison, 2018). Enamel erosion occurs when acids wear away at the teeth and can result in painful temperature sensitivity, discolouration, cracks and chips, and indentations appearing on the teeth, and will result in cavities (Smith, 2013).
Background Research Teeth come in different shapes and sizes and everyones ' teeth are different. However all teeth have a few things in common- they all have three main layers; Enamel, Dentin, and Pulp. Enamel is the very hard protective shell on the visible part or crown of your tooth. It can withstand chewing and biting but is brittle and can chip/break easily. Dentin consists of a substance that is similar to bone, it is underneath the enamel and gives your teeth their color.
The extra teeth had grown to almost cover the entire top of his mouth. Some teeth were large or average in size while others were close to 5 times smaller than the biggest tooth. This was interesting to the doctor for he wondered if this made it hard for Joe to speak because he hadn’t spoken much since they met. It made sense that the teeth covering the top area of his mouth where making it hard to speak because this is where the tongue is suppose to hit to create various sounds that become words. Regardless of his speech capabilities, further testing showed that the Wnt signaling pathway that controls the growth rate of teeth was induced to a much greater extent in Joe.
A satisfactory sociological explanation of the fluoridation controversy remains elusive. Despite decades of research on the topic, the persistence and passion of the fluoridation debates are yet incompletely understood by social scientists (Frazier 1980, p. 214). I would support the fluoridation on several basis. Fluoride has been known to help in protecting the teeth in the following ways: • Protection from demineralization – In the event that bacteria in the mouth mix with sugars the final product is acid.
Cavities to many people are usually painless thus difficult to discover them but the most common cavity symptom are an increased sensational to cold sweet foods and beverages .Cavities in hospitals are usually detected by hands –on and radiographic examinations Treatment of teeth cavities may involve a procedure called filling, this involves filling the teeth by removing the decayed tooth and replacing it with a material such as silver alloy, gold or porcelain. Porcelain is usually preferred for the front tooth as it usually looks like a natural tooth .The case where the tooth decay is extensive it is highly advisable to use crowns ,the weakened teeth is removed and fitted with a crown which can be made of gold or porcelain. If you use fillings you may increase the chances of the teeth breaking.
Both crowned and controlled dentition had no variances in the amount of bone loss. 3- Influence of oral hygiene on the mucosal conditions beneath bridge pontics (Tolboe et al. 1987) In this study patients went through a period of trial of 3 months.
Gum is the leading cause of cavities. I wondered if this is why I had 13 cavities. I learned that the bacteria sitting on your mouth breaks down the sugar in the gum and causes acid, once the acid has been sitting on your teeth for a while it creates a cavity in your tooth. I learned that gum also has a very negative effect on teeth. If gum does cause cavities continuing to chew gum is even worse because most cavities today are filled with mercury and frequent chewing may cause dislodging and releasing of dangerous materials in your metabolism.
Having problems with your teeth can cause all sorts of stress. In order to deal with these problems, you can take these effective steps. Get Dental Crowns If you have a weak tooth that is starting to decay, getting a dental crown put in by a dentist is a good idea. These crowns are placed on the weakened tooth, restoring its shape, size and color.
HEMISECTION AND BICUSPIDIZATION – A REVIEW ARTICLE Latest advances in dentistry has become a boon to patients to maintain a functional dentition for a lifetime. Retaining a teeth may involve combining restorative dentistry, endodontics and periodontics so that the teeth are retained in whole or in part. Thus tooth resection procedures are used to preserve as much tooth structure as possible rather than sacrificing the whole tooth.(1)(2) The term tooth resection denotes the excision and removal of any segment of the tooth or a root with or without its accompanying crown portion. Various resection procedures described are : root amputation, hemisection, radisection and bisection.
