0 a condition in which the tissue around the teeth becomes swollen and the gums (= the pink flesh in the mouth into which the teeth are fixed) move away from the teeth
A definite association between periodontitis or gingivitis and systemic infections has not been established but there is circumstantial evidence that it may occur.
Methods for diagnosing, preventing, and treating periodontitis.
Sequelae of a necrotic pulp include acute apical periodontitis, dental abscess or radicular cyst and discolouration of the tooth that may require tooth bleaching.
Anaerobic bacteria are especially dangerous to the gingiva and the gingival fibers that attach the teeth to the gums, leading to periodontitis.
Periodontitis is caused by microorganisms that adhere to and grow on the tooth's surfaces, along with an over-aggressive immune response against these microorganisms.
Chronic periodontitis affects about 750 million people or about 10.8% of the population as of 2010.
Historically treatment of periodontitis has been focussed on reducing the bacterial challenge.
Another cause is due to untreated necrotic pulp (chronic apical periodontitis).
