Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis. Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses. Viruses that specifically infect bacteria—bacteriophages—are most common in the oral ...
Rather than a single disease entity, periodontal disease is a combination of multiple disease processes that share a common clinical manifestation. The cause includes both local and systemic factors. The disease consists of a chronic inflammation associated with loss of alveolar bone. Advanced disease features include pus and exudates.
This involves regular checkups and detailed cleanings every three months to prevent repopulation of periodontitis-causing microorganisms, and to closely monitor affected teeth so early treatment can be rendered if the disease recurs. Usually, periodontal disease exists due to poor plaque control resulting from inappropriate brushing.
A difficulty which arises with diagnosing chronic periodontitis patients is due to the slow and painless progression of the disease. [6] The most effective and timely diagnosis would be during the mild to moderate stage. However, usually when presenting complaints do arise the effects of mobility and alveolar bone loss have become severe.
Periapical periodontitis of some form is a very common condition. The prevalence of periapical periodontitis is generally reported to vary according to age group, e.g. 33% in those aged 20–30, 40% in 30- to 40-year-olds, 48% in 40- to 50-year-olds, 57% in 50- to 60-year-olds and 62% in those over the age of 60.

At the time the system was designed, the initiation of periodontal disease was thought to develop from a continuum from an inflammation-free state to gingivitis, to calculus deposition and pocket formation and then to progressive disease. Treatment concepts were based on the concept of pocket depths being the most critical criterion for ...
Accumulated bacteria, due to the onset of periodontitis from dental plaque, may gain access to distant sites in the body through the circulatory and respiratory system, potentially contributing to various systematic diseases and conditions. Due to the infectious nature of bacteria hosted within the oral cavity, bacteria produced cavity can ...
The diseases appear to represent different severities or stages of the same disease process, although this is not completely certain. These diseases usually have a sudden onset. The mildest on the spectrum is necrotizing gingivitis (NG), followed by the successively more severe conditions necrotizing periodontitis (NP), necrotizing stomatitis ...
