"Adult periodontitis" was reclassified "chronic periodontitis" and "early-onset periodontitis" to "aggressive periodontitis". [1] This article follows the 1999 classification, although the ICD-10 (10th revision of the International Statistical Classification of Diseases and Related Health Problems) differs significantly.
Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. In response to endotoxin derived from periodontal pathogens, several osteoclast-related mediators target the destruction of alveolar bone and supporting connective tissue such as the periodontal ligament.
Generally, diseases outlined within the ICD-10 codes K05-K06 within Chapter XI: Diseases of the digestive system should be included in this category. Pages in category "Periodontal disorders" The following 36 pages are in this category, out of 36 total.
Periapical periodontitis or apical periodontitis [9] (AP) is an acute or chronic inflammatory lesion around the apex of a tooth root, most commonly caused by bacterial invasion of the pulp of the tooth. [10]
This can be caused by tooth decay, broken teeth or extensive periodontal disease (or combinations of these factors). A failed root canal treatment may also create a similar abscess. A dental abscess is a type of odontogenic infection , although commonly the latter term is applied to an infection which has spread outside the local region around ...
The often severe gum pain that characterizes NG distinguishes it from the more common gingivitis or chronic periodontitis which is rarely painful. If NG is improperly treated or neglected, it may become chronic and/or recurrent. The causative organisms are mostly anaerobic bacteria, particularly Fusobacteriota and spirochete species.
A periodontal abscess most commonly occurs as a complication of advanced periodontal disease. [5] A periodontal pocket contains dental plaque, bacteria and subgingival calculus. [6] Periodontal pathogens continually find their way into the soft tissues, but normally they are held in check by the immune system. [7]
Periodontitis and dental caries may develop on either the third or second molars, and chronic inflammation develops in the soft tissues. Chronic pericoronitis may not cause any pain, but an acute pericoronitis episode is often associated with pericoronal abscess formation.
