The acid comes from the bacteria from the plaque bio lm & the fermented carbs acting over tooth surface. Irreversible Enamelhas a small ofproteinwhichwillgetdestructed amount can re depositthe minerals OBernsiblecuz you PLAQUE FILM Plaque bio lm is a layer that is present on our oral cavity that is being deposited. Formation: saliva coats on the tooth surfaces. Glycoprotein that’s present in the saliva will coat the surface (which is a sticky surface). That makes the carbs/bacteria to stick over it. Even if you brush your teeth, there’ll be bacteria (oral inhabitants) stable inside our oral cavity. So even if you brush you teeth, when the saliva coats your teeth, the bacteria will adhere and coat the tooth surface due to the presence of the sticky surface. So if you don’t remove the plaque for a long time due to habits like eating a lot of sugar or not brushing teeth properly, then that will settle over there, and if left for a long period of time, then you’ll get these reactions (like fermentation of carbs) which will lead to acids which will cause demineralization and proteolytic destruction. When it’s restricted only to acid demineralization, that means this is gonna be only on the enamel which is possibly a reversible process. But when proteolytic destruction happens, this is something that can happen when it’s irreversible. When demineralization happens, that means you can always reminerlize the area by applying reminerlization solution. If you nd the area demineralized, you will be able to identify that and apply a reminerlization solution or tooth paste, the tooth can get reminderlized. You can deposit the minerals over there. But if there’s proteolytic destruction, then it’s irreversible. At that stage, the Caries will be reached at the irreversible stage.

A) Frequent and prolonged exposure of the teeth to dietary carbohydrates generates an acidic plaque environment, which promotes the demineralization of the dental enamel, causing caries Dental caries in the teeth of children and infants. No othercarieshappened on thattooth Caries can happen in a tooth that already had Caries.

Root is made of cementum only. No enamel in the root. Q) What’s the cover of the root? A) Dentine and there’s no enamel. And a very thin layer of cementum covering it. In the crown, the enamel Difffrom will be the covering. In the root, the cementum cervical caries will be the covering. You can never see the cementum. It’s a very thin covering.

If there are caries in the roof side of the cemento-enamel junction, it’s considered a root caries. brown discoloration childhood Nownamed early caries wordfound intextbookbutcan notbe used Formed in a shortperiod oftime Existing for a while notnew If yougoogle itYou'llsee a conditionthat happens in th neck bone Early caries can’t be identi ed by the patient. If the patient can identify the caries then it’s a progressive caries. Early caries can only be identi ed by a professional. Needs to bepresent forenoughamountoftime These are the most identi ed type of bacteria that cause caries. But we can’t identify a speci c type of bacteria that causes caries. imp Groove susceptible Pits fissures Any surface that has pits and ssure can become a susceptible tooth surface. "Occlusal" refers to the surface of the tooth that is used for chewing or grinding. piercethroughthegingivalconesout Because you have a lot of debris accumulating it is always at the risk of getting caries. So sometimes even when tooth is erupting itself, it will become a risk area. But the problem is that when vou have an erupting molar and when you tend to brush your tooth, it will be below the level of the brush so we usually miss out those surfaces unless otherwise you speci cally put in e ort to pull out your cheeks position to brush over that erupting tooth, otherwise it will not come on the surface of brushing. Any area that can’t be reached by the tooth brush is considered a susceptible area.
