How did acute pulpitis come from?

Dental pulp is the main part of our teeth, and the nutritional activities of teeth need dental pulp to supply. So when the pulp of our teeth has problems or necrosis, our teeth will be hurt first, and sometimes they can no longer be used. So, how did the general acute pulpitis come from?

1, acute pulpitis

Acute pulpitis refers to acute inflammation of dental pulp tissue, and its infection source mainly comes from deep dental pulp. Dental pulp infection can cause apical infection through apical foramen. The main clinical manifestation is severe pain, but the effect of general analgesic drugs is not obvious, and it can develop into pulp gangrene in the later stage. The main treatment methods are pulp opening and drug analgesia.

Pathogenesis of (1)

Infection is the main cause. Infection can be secondary to deep caries and other serious tooth defects, and can also be caused by periodontal tissue diseases. Infection enters the pulp retrograde through the apical or accessory root orifice, causing pulpitis. At the same time, blood sources can also cause lovely dyeing. In the treatment of deep caries, drugs used to disinfect dental cavities will stimulate dental pulp and cause acute pulpitis. When high-speed pneumatic electro-conversion is used to drill and grind teeth, when the local temperature exceeds the tolerance limit of pulp tissue (20.

(2) Clinical symptoms

Pain is its main manifestation, which is severe and unbearable. The nature of pain has the following characteristics: spontaneous pain, paroxysmal aggravation, intermittent attack, severe tooth pain without any external stimulation, short onset time of early pain and long remission time, long onset time of late pain with the development of the disease, short remission time, and even no remission period at last; The pain at night is heavier than during the day, especially when lying down; Early cold and hot stimulation will aggravate the pain, while later cold stimulation not only does not stimulate the pain, but temporarily relieves the pain. Therefore, it is common to use cold water in your mouth or suck cold air to relieve pain. People often say that "toothache is not a disease, but it will kill people when it hurts", which refers to the symptoms of the late stage of acute pulpitis (suppurative stage); Furthermore, the pain can not be located, and it often radiates to the upper and lower teeth and adjacent parts along the distribution area of trigeminal nerve. Patients are usually unable to point out the exact location of the diseased tooth.

Step 2 diagnose

It is not difficult to diagnose according to clinical manifestations, and it needs to be differentiated from the following diseases:

1, differentiated from deep caries: all of them have deep cavities, but deep caries have no spontaneous severe pain of acute pulpitis.

2. Differentiation from gingivitis: Gingivitis may have spontaneous and severe pain, but the local gums are red, swollen, tender and even purulent, with a history of food impaction. But pulpitis is not, pulpitis is sensitive to temperature, and gingivitis has no obvious response to temperature stimulation.

3. Differentiation from trigeminal neuralgia: Trigeminal neuralgia generally does not attack at night, and temperature changes will not cause pain, and there are many "trigger points", and the pain interval will not be significantly prolonged or shortened with the development of the disease.

3. Auxiliary inspection

X-ray or oral photography to know whether there is acute pulpitis.

Step 4 deal with

The principle of treatment is to keep the vital pulp or the affected teeth. After emergency treatment, the pulp can be opened and decompressed. After washing with warm salt water, put analgesic drugs (such as camphor phenol, eugenol or toothache water) into the cavity to temporarily relieve the pain. Take anti-inflammatory and analgesic drugs at the same time. After the pain was relieved, 1-2 days, depending on the specific situation of the affected teeth, 1, vital pulpotomy was selected; 2. Leveling the slurry; 3. Dental pulp plastic replacement or root canal therapy. It can extract teeth without reserved value, relieve the pain of patients and prevent the spread of diseases. Prevention: Maintain oral hygiene, develop a good habit of brushing your teeth in the morning and evening, and avoid tooth damage and cold and hot stimulation.

5, the cause of pulpitis

1, tooth decay

Dental caries is a common dental disease. There are many cases of pulp inflammation after dental caries. Serious dental caries can cause dental pulp exposure and infection, resulting in inflammation and pain.

2. Tooth damage

The types of tooth injury mainly include crown root injury and pulp disease caused by tooth trauma, and the degree of tooth injury is closely related to pulpitis. Traumatic pulp exposure can directly cause pulpitis; After the teeth are slightly shaken, the pulp may or may not be inflamed.

3. Tooth wear

Tooth wear is more common in the elderly because tooth enamel will wear after decades of chewing. The pulpitis caused by tooth wear generally has the characteristics that the tooth tissue defect is more painful and closer to the pulp. The way of pulpitis caused by tooth wear is caused by dentinal tubules.

4. Congenital malformation

Common starvation congenital malformations include central apex abnormality and lingual fossa pulp necrosis. Dental pulp infection caused by wear of deformed central tip; Abnormal lingual fossa is often embedded with food, which leads to pulp infection.

5. Wedge defect

Improper brushing methods will cause dental neck defects, and serious defects will lead to dental pulp exposure and inflammation. Wedge-shaped defects can also cause pulpitis due to the stimulation of chemicals on dental pulp, such as composite resin repairing defects or disinfection of drugs at the bottom of holes to stimulate dental pulp and cause inflammation.

6. periodontitis

It is more common in retrograde infection caused by blind bag infection of severe periodontitis, that is to say, blind bag destroys the tissue around the root and affects the pulp tissue of the root.
