There are several cases of pulp disease as follows: I. Repeatable pulpitis, when there is a repeatable pulpitis, you can remove the decaying matter after the pacification treatment, and do not eat with the affected tooth in the near future, and wait for about half a month to fill the tooth when there are no symptoms. Chronic pulpitis, when there is chronic pulpitis, there is usually a vague pain in the tooth, in this case, nerve killing treatment is needed. Indirect pulp capping is generally used when the tooth is about to be exposed, or when there is already pitting pulp, direct pulp capping can be done, and the common preparation is calcium hydroxide preparation. Fourth, acute pulpitis, when there is acute pulpitis, generally choose to open the pulp under anesthesia, that is, the tooth will be drilled open, exposing the pulp cavity, sealing the nerve-killing drugs can quickly relieve pain, usually now the choice is a thorough root canal treatment, individual old and frail people can choose to do dry pulp treatment.
