Text A

Acute Periodontitis.

There are various sources of the inflammatory processes of the facio-mandibular region of the oral cavity. The most frequent causes of them are chronic periodontosis, hard eruption of the wisdom teeth, alveolitis, purulent cysts, so on.

But each of them has its own peculiar course, which defines a diagnosis and a course of treatment.

The infection comes into the periodontal chink through the tooth canal or marginally. The patient complains of the pain on pressing and percussion of the affected tooth. The gum around the tooth becomes swollen; regional lymphatic glands become enlarged and painful. A serous inflammation of the periodontium is developing quickly. Gradually the pain in the tooth and in a surrounding tissue becomes pulsating, the body temperature rises up 37,5 - 38 C. An abscess is developing in a periodontal chink. The same clinical picture can be observed both in a chronic and in an acute periodontitis. The treatment is surgical. Opening of the seat of the abscess must be performed at the earliest stage of the purulent periodontitis till the purulent process does not overcome the alveolus. However the evacuation of the pus through the tooth canal is possible if the canal is well permeable, that is mainly in incisors, canines and sometimes in premolars. In other cases the pus overflow takes place through the alveolus by the extraction of the affected teeth.
