Apodontitis refers to periapical inflammation, and the complete cure is based on the specific condition. Surgical treatment is performed by a doctor, and medication is prescribed as necessary to assist in the treatment. Periodontitis is an inflammatory disease that occurs in the tissues surrounding the root tip of the tooth. The main reason why there is no cure for periapical infection is that as long as there is a tooth, even if the affected tooth is extracted, there is no guarantee that the other teeth will not be affected by bacterial infections, physical irritation and other factors that could lead to the reoccurrence of periapical inflammation in the future. The prognosis for this disease is generally good with prompt treatment. For patients with obvious symptoms and spreading inflammation, surgical treatments such as endodontics, pulpal revascularization, or tooth extraction are required, as well as the use of antibiotics such as cefuroxime and metronidazole, and non-steroidal anti-inflammatory pain relievers such as ibuprofen and acetaminophen as an adjunct to the treatment. To summarize, patients with periapical inflammation need to go to the hospital in time, cooperate with the doctor to actively treat, and strengthen the management of oral hygiene.
