1. Pulpitis
Pulpitis is medical symptom in which
the dental pulp becomes inflamed.

2. • Once the pulp has become inflamed, the
tooth can be diagnostically divided into two
categories:
• Reversible Pulpitis
• Irreversible Pulpitis

3. Irreversible Pulpitis
• This is the condition where the pulp is
irreversibly damaged. The pulp can not recover
from the insult and damage. For example, decay
that has reached the pulp of the tooth introduces
bacteria into the pulp. The pulp is still alive, but
the introduction of bacteria into the pulp will not
allow the pulp to heal and it will ultimately result
in necrosis, or death, of the pulp tissue.

4. Appearance

5. Causes:
• When a dentist needs to remove lots of dentin due to big
cavities and gets really close to the pulp.
• When the blood flow to the pulp gets decreased or
removed. This could be caused by orthodontic treatment,
such as braces, that makes the tooth move so fast that the
blood vessels can't keep up and the pulp's blood supply gets
cut off. It could also be caused by trauma that severs the
blood vessels and slowly kills the pulp.
• Very deep cavities that go through the enamel and all the way
through the enamel right into the pulp. The bacteria then
cause inflammation in the pulp. The more the body tries to
fight off the bacteria, the higher the pressure gets inside the
tooth until the pressure may strangle the blood vessels and
cause the pulp to die.

6. Management:
• The pulp of a tooth with irreversible pulpitis may not be left
alone to heal. The tooth may be endodontically treated
whereby the pulp is removed and replaced by gutta percha.
An alternative is extraction of the tooth. This may be required
if there is insufficient coronal tissue remaining for restoration
once the root canal therapy has been completed.
• Root canal or tooth extraction.
• Do not delay management more than a few days.

7. Reversible Pulpitis
• This is the condition where the pulp is inflamed
and is actively responding to an irritant. This may
include a carious lesion that has not reached the
pulp.
• Symptoms include transient pain or sensitivity
resulting from many stimuli, notably
hot, cold, sweet, water and touch. The pulp is still
considered to be vital. This means that once the
irritant is eliminated, usually by removal of decay
and the placement of a filling, that the pulp will
return to its normal, healthy state.

8. Apperance

9. Causes:
• Cavities that haven't reached the nerve yet.
• Erosion of the tooth that reaches the dentin
• Drilling done by a dentist when doing a filling
or crown preparation on the tooth
• A fracture of the enamel layer of the
tooth which can expose the dentin
• Getting your teeth cleaned (scraped!) by a
dental hygienist, especially when they clean
the roots if you have periodontal disease.

10. Management:
• Dental Caries debris removed
• Dental filling applied
