The depth of cavity prep for composite in posterior:
a- Limited to enamel
b- 0.5 mm in dentin
c- Depends on caries extension***
d- Depends on tooth discoloration
e- 0.2 mm in dentin.
Caries is the most common dental pathology around the world. Not supported, it can have disastrous consequences on dental health and even on general health. His treatment is simple. How to cure decay?
Caries is the gradual destruction of the tooth, which results from acid attack of enamel by bacteria. When it is not treated, it spreads gradually and can even attack all the surrounding tissues: ligaments, bones, gums ...
Why do I have cavities?
There are four main factors that can cause the appearance of cavities:
- Dental plaque: more or less whitish substance consisting of saliva, food deposits and bacteria, it is formed on the surface of the teeth after each food intake and eats the enamel;
- Poor oral hygiene: irregular or incorrect brushing is the royal route for any bacterial proliferation, with a greater carious risk. It is thanks to an effective brushing of teeth that one removes the dental plaque;
- Heredity: it seems that there is a genetic predisposition to caries within certain families;
- An unbalanced diet: the consumption of sugars promotes the development of caries, as the nibbling. The consumption of fruit juice, syrups and other sodas is also limited: in addition to being sweet, they acidify the oral environment, which promotes the development of cavities.
THE FOUR STAGES OF CARIE:
1. Destruction of enamel: at this stage, decay is completely painless;
2. The dentine is attacked: the tooth is sensitive to cold, heat, sugar and acid;
3. Achievement of the pulp: violent pains can appear, spontaneous or caused by hot and cold ... It's tooth rage! ;
4. Formation of an abscess: the bacterial proliferation reaches the tissues around the tooth (bone, ligament, gum). Even though the initial pain has disappeared, more or less long term, it will form an abscess, which can become painful overnight.
Treat a shallow decay:
When decay is not very advanced, the goal of care is to preserve the pulp and keep the tooth alive. After having carefully removed the decay, the dentist will put an amalgam (which is still called lead although it is not lead but silver powder and mercury) or a composite cement color identical to the tooth .
It will then reconstitute the shape of the tooth and there will be no more trace of the decayed caries. A more recent technique is to use small blocks of metal or resin called inlays to reform the tooth. They are made from an impression of the tooth, the process is longer (2 sessions) and especially much more expensive. On the other hand, these inlays are more resistant and do not need to be changed before 10 years.
Caries care is now most often performed with local anesthesia. Your dentist will be able to use several different techniques of anesthesia so that no pain is felt during the treatment. The era of suffering in the dental office is well over. And if the tooth is too damaged to settle for an amalgam, we will go to great means.
In case of deep caries, the devitalization of the tooth
When the decay is too deep, we will unfortunately not be able to keep the tooth alive. Once the pulp is reached, it is necessary, to prevent pain (and inevitable toothache), to devitalize the diseased tooth (remove the vital tissue of the tooth). Devitalization is performed under local anesthesia.
