The most common cause of pulpitis would be deep cavities as this exposes the pulp to the bacteria that has built up inside the mouth, and that, in turn, leads to pulp becoming inflamed.
There are three categories under physical causes and these include mechanical injury, thermal injury, and electrical injury.
- Mechanical injury. Trauma, cracked tooth syndrome, barodontalgia, and pathologic wear are under this category.
- Thermal injury.This comes from the heat in cavity preparations. The heat from procedures like restoration and polishing is also under thermal injury. The eat that comes from the setting of cement on the teeth is another thermal injury. Lastly, when the teeth are exposed to direct heat and cold due to the lack of a protective base during deep filling procedures, this will result in thermal injury.
- Electrical injury.This is caused by a sudden surge of electrical current to the oral cavity. This is most common in children and infants since they have the tendency to nibble on the cords of electrical appliances.
Symptoms of Pulpitis
The following are key signs and symptoms.
- General pain is present in reversible pulpitis, irreversible pulpitis, chronic pulpitis, and acute pulpitis
- Teeth sensitivity is short and sharp for reversible pulpitis and chronic pulpitis. The pain lasts 30 seconds when it comes to irreversible pulpitis, and the pain is excruciating for acute pulpitis.
- The area around the teeth is swelling for patients with irreversible pulpitis and acute pulpitis. As for reversible pulpitis and chronic pulpitis, it rarely occurs.
- Fever is present for patients with irreversible pulpitis and acute pulpitis. Fever rarely happens for patients with reversible pulpitis and chronic pulpitis
- Bad breath is present in irreversible pulpitis. It is not present in reversible pulpitis and it can possibly occur in patients with chronic pulpitis and acute pulpitis.
- There will be an increase in pain felt by a person with irreversible pulpitis and acute pulpitis. For those with reversible pulpitis and chronic pulpitis, they will not feel this.
Diagnosis of Pulpitis
Dentists will perform a series of tests in order to determine the diagnosis of the patient. Through these tests, dentists will be able to identify what type of pulpitis a patient has.
- Tooth tap test
- Electric testing
- Exposure to sweets, cold, and heat
