Smoking is a generalized risk factor for generalized forms of aggressive periodontitis. Studies found that smokers have more affected teeth than non-smokers and high levels of attachment loss. This is due to the suppression of serum IgG2 and antibody against Aggregatibacter actinomycetemcomitans found in smokers. [16]
Aggressive periodontitis was found in 5.9% of the subjects (4.3% localized and 1.6% generalized). This was significantly associated with current smoking and ethnic origin (North African). [citation needed] Eres 2009 examined 3,056 students between the ages of 13 and 19 years at public schools in Turkey.
Linear gingival erythema presents as a localized or generalized, linear band of erythematous (red) gingivitis. It was first observed in HIV infected individuals and termed "HIV-gingivitis", but the condition is not confined to this group. [7] This condition can develop into necrotizing ulcerative periodontitis. [5]
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.
Periodontitis is very common, and is widely regarded as the second most common dental disease worldwide, after dental decay, and in the United States has a prevalence of 30–50% of the population, but only about 10% have severe forms. Chronic periodontitis affects about 750 million people or about 10.8% of the world population as of 2010. [86]
Common causes include inflammation of the pulp, (usually in response to tooth decay, dental trauma, or other factors), dentin hypersensitivity, apical periodontitis (inflammation of the periodontal ligament and alveolar bone around the root apex), dental abscesses (localized collections of pus), alveolar osteitis ("dry socket", a possible ...
If there is attachment loss, and no other systemic condition, then the diagnosis will be periodontitis. Using the periodontal six/four point chart, if more than 30% of sites are involved then a diagnosis of generalised disease is given. If less than 30% of sites are involved, then the type of periodontitis is localized.
Periodontology or periodontics (from Ancient Greek περί, perí – 'around'; and ὀδούς, odoús – 'tooth', genitive ὀδόντος, odóntos) is the specialty of dentistry that studies supporting structures of teeth, as well as diseases and conditions that affect them.
