Acute pericoronitis

Does everyone know about acute pericoronitis? Do you know what kind of disease it is? Acute pericoronitis is very common among young people, especially in the age group of 18 to 26 years old. This disease will have many effects on patients, including bloating and pain, which will affect chewing and smoking. Once you open your mouth, you will feel pain. Everyone should seek treatment in time to avoid it from developing into a chronic disease.

Acute pericoronitis is a disease caused by the eruption of our teeth, which is especially common among young people. Once you suffer from such complications, it will have a great impact on your life. Let us have a comprehensive understanding of this disease.

Pericoronitis is a complication caused by tooth eruption, which is mainly manifested as inflammation of the soft tissue around the crown. Clinically, the most common one is the mandibular third molar (commonly known as wisdom tooth). Secondly, the maxillary third molar may also occur. This disease often occurs between the ages of 18 and 30. Etiology, pathology and mechanism: Difficulty in the eruption of the third molar is the main cause of pericoronitis. This is caused by the mismatch of the eruption position of the molars, which is related to the gradual degeneration of the mandible due to changes in food, living habits and chewing force during the occurrence and evolution of the human lineage. The type of molar impaction also has a certain impact on the occurrence of pericoronitis.

Clinically, partial vertical impaction and mesial oblique impaction are the most common and most often cause pericoronitis. The position of incompletely erupted tooth crowns is mostly lower than the occlusal plane of the second molar. The distal, buccal and lingual sides are often covered by gingival flaps, forming a deep and narrow blind pocket between the gingival flap and the crown. It has poor self-cleaning effect and is easy to hide food residues. Its temperature and humidity are good conditions for bacterial growth and reproduction. Under normal circumstances, the human body has strong resistance and bacteria cannot succeed. However, when the human body has a cold, lacks sleep, is fatigued, etc., the body's resistance is reduced, and bacteria multiply and cause infection.

Mechanical damage to the gingival flap during biting and chewing causes ulceration of the mucosa, destroys the defense function of the tissue, allows bacteria to enter, and can also cause pericoronitis. The clinical manifestations of pericoronitis are initially painful and swollen gums, which worsen during chewing and swallowing. The pain may worsen when the mouth is opened. When the infection spreads to the masseter muscles and medial pterygoid muscles, the jaw may be locked. Local swelling may occur, and the lymph nodes may become enlarged and tender. Systemic symptoms may appear at this time, such as general discomfort, fever and increased white blood cell count. If the pain persists and the fever persists within 2 to 3 days of onset, it may be considered that the inflammation has developed into the suppurative stage. If incision and drainage are performed in time during this period, the inflammation will gradually subside. If the infection is not controlled during this period, the inflammation will spread. The infection can spread to the masseter muscles, cheeks, parapharyngeal muscles, mandible, etc., causing interstitial infection in the corresponding spaces. And can further cause various serious complications.

Generally, there are no obvious symptoms in the early stages of acute pericoronitis, and there are no obvious symptoms in the whole body. Generally, the pain will be obvious when opening the mouth. During examination, purulent secretions will be found in the pericoronary bag. This requires timely treatment. If it is not treated as soon as possible, it will develop into a chronic disease and have a great impact on the body.
