Linear gingival erythema

Last updated

Linear gingival erythema (LGE) is a periodontal disorder diagnosed based on distinct clinical characteristics. It was originally thought that LGE was directly associated with HIV, and it was thus called HIV-associated gingivitis (HIV-G). Later research confirmed that LGE also occurs in HIV negative immunocompromised patients, and it was thus renamed. [1]

Periodontium the structures surrounding and supporting the tooth

The periodontium is the specialized tissues that both surround and support the teeth, maintaining them in the maxillary and mandibular bones. The word comes from the Greek terms περί peri-, meaning "around" and -odont, meaning "tooth". Literally taken, it means that which is "around the tooth". Periodontics is the dental specialty that relates specifically to the care and maintenance of these tissues. It provides the support necessary to maintain teeth in function. It consists of four principal components, namely:

HIV human retrovirus, cause of AIDS

The human immunodeficiency viruses (HIV) are two species of Lentivirus that causes HIV infection and over time acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. In most cases, HIV is a sexually transmitted infection and occurs by contact with or transfer of blood, pre-ejaculate, semen, and vaginal fluids. Non-sexual transmission can occur from an infected mother to her infant during pregnancy, during childbirth by exposure to her blood or vaginal fluid, and through breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.

Presentation

LGE is limited to the soft tissue of the periodontium, appearing as a red line 2–3 mm in width adjacent to the free gingival margin. Unlike conventional periodontal disease, though, LGE is not significantly associated with increased levels of dental plaque. [1]

Dental plaque is a biofilm or mass of bacteria that grows on surfaces within the mouth. It is a sticky colorless deposit at first, but when it forms tartar, it is often brown or pale yellow. It is commonly found between the teeth, on the front of teeth, behind teeth, on chewing surfaces, along the gumline, or below the gumline cervical margins. Dental plaque is also known as microbial plaque, oral biofilm, dental biofilm, dental plaque biofilm or bacterial plaque biofilm. Bacterial plaque is one of the major causes for dental decay and gum disease.

The prevalence of LGE remains unclear [2] and there is no known treatment.

Prevalence in epidemiology is the proportion of a particular population found to be affected by a medical condition. It is derived by comparing the number of people found to have the condition with the total number of people studied, and is usually expressed as a fraction, as a percentage, or as the number of cases per 10,000 or 100,000 people. Point prevalence is the proportion of a population that has the condition at a specific point in time. Period prevalence is the proportion of a population that has the condition at some time during a given period, and includes people who already have the condition at the start of the study period as well as those who acquire it during that period. Lifetime prevalence (LTP) is the proportion of a population that at some point in their life have experienced the condition.

Periodontal disease human disease of the tissues surrounding the teeth

Periodontal disease, also known as gum disease, is a set of inflammatory conditions affecting the tissues surrounding the teeth. In its early stage, called gingivitis, the gums become swollen, red, and may bleed. In its more serious form, called periodontitis, the gums can pull away from the tooth, bone can be lost, and the teeth may loosen or fall out. Bad breath may also occur.

Acute necrotizing ulcerative gingivitis Human disease

Acute necrotizing ulcerative gingivitis is a common, non-contagious infection of the gums with sudden onset. The main features are painful, bleeding gums, and ulceration of inter-dental papillae. This disease, along with necrotizing (ulcerative) periodontitis is classified as a necrotizing periodontal disease, one of the seven general types of periodontitis. The often severe gingival pain that characterizes ANUG distinguishes it from the more common chronic periodontitis which is rarely painful. ANUG is the acute presentation of necrotizing ulcerative gingivitis (NUG), which is the usual course the disease takes. If improperly treated or neglected, NUG may become chronic and/or recurrent. The causative organisms are mostly anaerobic bacteria, particularly Fusobacteria and spirochete species. Predisposing factors include poor oral hygiene, smoking, malnutrition, psychological stress and immunosuppression. When the attachments of the teeth to the bone are involved, the term NUP is used. Treatment of ANUG is by debridement and antibiotics in the acute phase, and improving oral hygiene to prevent recurrence. Although the condition has a rapid onset and is debilitating, it usually resolves quickly and does no serious harm. The synonym "trench mouth" arose during World War I as many soldiers developed the disease, probably because of the poor conditions and extreme psychological stress.

Gums mucosal tissue that lies over the mandible and maxilla inside the mouth

The gums or gingiva, consist of the mucosal tissue that lies over the mandible and maxilla inside the mouth. Gum health and disease can have an effect on general health.

Curettage

Curettage, in medical procedures, is the use of a curette to remove tissue by scraping or scooping.

The current staging system for HIV infection in children was developed in 2005 and builds upon the staging system in place since 1987. A child is defined as someone under the age of 15. This staging system also requires the presence of HIV infection: HIV antibody for children aged 18 months or more; virological or p24 antigen positive test if aged under 18 months.

A periodontal probe is an instrument in dentistry commonly used in the dental armamentarium. It is usually long, thin, and blunted at the end. The primary purpose of a periodontal probe is to measure pocket depths around a tooth in order to establish the state of health of the periodontium. There are markings inscribed onto the head of the instrument for accuracy and readability.

LGE may refer to:

Gingival sulcus

The gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin. A healthy sulcular depth is three millimeters or less, which is readily self-cleansable with a properly used toothbrush or the supplemental use of other oral hygiene aids.

Gingival and periodontal pocket

Gingival and periodontal pockets are dental terms indicating the presence of an abnormal depth of the gingival sulcus near the point at which the gingival tissue contacts the tooth.

Bleeding on probing which is also known as bleeding gums or gingival bleeding is a term used by dentists and dental hygienists when referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth. Bleeding on probing, often abbreviated BOP, is a sign of inflammation and indicates some sort of destruction and erosion to the lining of the sulcus or the ulceration of sulcular epithelium. The blood comes from lamina propria after the ulceration of the lining.

Gingival enlargement Human disease

Gingival enlargement is an increase in the size of the gingiva (gums). It is a common feature of gingival disease. Gingival enlargement can be caused by a number of factors, including inflammatory conditions and the side effects of certain medications. The treatment is based on the cause. A closely related term is epulis, denoting a localized tumor on the gingiva.

The junctional epithelium (JE) is that epithelium which lies at, and in health also defines, the base of the gingival sulcus. The probing depth of the gingival sulcus is measured by a calibrated periodontal probe. In a healthy-case scenario, the probe is gently inserted, slides by the sulcular epithelium (SE), and is stopped by the epithelial attachment (EA). However, the probing depth of the gingival sulcus may be considerably different from the true histological gingival sulcus depth.

Gingivitis Human disease

Gingivitis is a non-destructive disease that causes inflammation of the gums. The most common form of gingivitis, and the most common form of periodontal disease overall, is in response to bacterial biofilms that is attached to tooth surfaces, termed plaque-induced gingivitis. Most forms of gingivitis are plaque-induced.

John Mankey Riggs American dentist

John Mankey Riggs was the leading authority on periodontal disease and its treatment in the United States, to the point that periodontal disease was known as "Riggs' disease."

Periodontal abscess

A periodontal abscess, is a localized collection of pus within the tissues of the periodontium. It is a type of dental abscess. A periodontal abscess occurs alongside a tooth, and is different from the more common periapical abscess, which represents the spread of infection from a dead tooth. To reflect this, sometimes the term "lateral (periodontal) abscess" is used. In contrast to a periapical abscess, periodontal abscesses are usually associated with a vital (living) tooth. Abscesses of the periodontium are acute bacterial infections classified primarily by location.

Chronic periodontitis chronic inflammatory process that affects the tissues that surround and support the teeth

Chronic periodontitis is a common disease of the oral cavity consisting of chronic inflammation of the periodontal tissues that is caused by the accumulation of profuse amounts of dental plaque. Periodontitis initially begins as gingivitis and can progress onto chronic and subsequent aggressive periodontitis according to the 1999 classification. Diagnosing chronic periodontitis is important in its early stages to prevent severe and irreversable damage to the protective and supportive structures of the tooth. However, due to chronic periodontitis being a painless progressing disease, few patients will seek dental care in the early stages. Mild to moderate chronic periodontitis can be managed by proper mechanical removal of the biofilm and calculus subgingivally. Full and effective oral hygiene and regular 3 monthly periodontal checkups are important for maintaining the stability of the disease.

Aggressive periodontitis describes a type of periodontal disease and includes two of the seven classifications of periodontitis:

  1. Localized aggressive periodontitis (LAP)
  2. Generalized aggressive periodontitis (GAP)

In dentistry, numerous types of classification schemes have been developed to describe the teeth and gum tissue in a way that categorizes various defects. All of these classification schemes combine to provide the periodontal diagnosis of the aforementioned tissues in their various states of health and disease.

Periodontal charting

Periodontal charting refers to a chart utilized by a dental care professional to write and record gingival and overall oral conditions relating to oral and periodontal health or disease.
