caries

Dentistry
Tooth decay. The destruction of tooth enamel and dentin, which is linked to infection by Streptococcus mutans and microaerophilic organisms that thrive when protected by a layer of hardened dental plaque; caries is most common in the young with refined carbohydrate-rich diets, especially in “snackers” who have increased oral pH; caries may affect older patients with diabetes, cancer or immunodeficient states.

Medical history
Obsolete for tuberculosis of bone and joints.
 
Orthopaedics
Osteolytic, softened and discoloured bone secondary to chronic periostitis and periperiosteitis, with formation of cold abscesses filled with a cheesy, fetid, pus-like substance, which extends through soft tissue to the surface via a sinus.

The nasal mucosa is highly vascular; blood is supplied by the maxillary arteries from the external carotid arteries and by the ethmoidal arteries from the internal carotid arteries.

Patient discussion about cavity

Q. What are the effects of alcoholism on the oral cavity? I have to make a presentation on this topic, and I would like to know what are the main pathological effects of chronic alcoholism on the oral cavity, I know that it is a carcinogen, but it mainly acts as a promoter, is there any cancer that is caused by alcohol abuse?

A. alcohol can interact harmfully with several medications commonly used in dental treatment. Alcohol intensifies the depressant effect of barbituates and tranquilizers creating a higher risk of deep sedation and unconsciousness. Following treatment, the ability to drive may be impaired. Medications used to control high blood pressure and angina have a dilating effect on the blood vessels which is intensified by alcohol.

The result is a higher likelihood of low blood pressure and fainting. Even the action of aspirin is intensified by alcohol, causing excessive bleeding by disrupting clot formation

Q. what happens if a dentist fills a cavity with some caries left on the tooth? the cavity was deep ,close to the nerve. Didn’t make nerve exposure.?

A. If it wasn’t removed properly – you will have what they call – “recurrent cries”. It’ll continue growing without you seeing it until you’ll come back to the dentist again because of the pain. I suggest you’ll save the pain part and go now.

Q. what happens if a dentist fills a cavity with some caries left on the tooth? the cavity was deep ,close to the nerve. Didn’t make nerve exposure.?

A. If that is so, then you will need to have him remove all the decay, the refill. If it is too close to the nerves then they may have to do a root canal. That means take out the filling, the tooth pulp and fill it up.
