Gingivitis Clinical Presentation

History
Historical findings depend on whether the patient has chronic gingivitis or ANUG.
- Chronic gingivitis
- The most common complaint is bleeding gums. The patient usually notices this when toothbrushing or flossing.
- Bleeding may be associated with eating, especially foods with a hard consistency, such as apples or crusted bread. These foods may rub against gums.
- Acute necrotizing ulcerative gingivitis
- Apparently spontaneous bleeding or bleeding in response to very minimal local trauma may occur.
- ANUG also may produce local pain, malaise, and alterations in taste, such as a metallic flavor.
- ANUG may produce foul breath.
Physical
- Chronic gingivitis
- Patients have minimal physical findings aside from local findings at the dental-gingival margins.
- Gingival pockets may be detected with a periodontal probe. However, the pocket depth may be overestimated when periodontitis is present and underestimated in healthy gums.
- Mild bleeding from the gum margins may occur with any manipulation.
- Acute necrotizing ulcerative gingivitis
- Fever, halitosis, marked gingival edema, and ulceration, especially in the interdental papillae, may be present.
- A grey pseudomembrane may be present.
- Infection may spread to adjacent soft tissues of the mouth, with noticeable erythema, edema, tenderness, and induration of affected areas.
- Reaction to oral contraceptives (see Causes)
Causes
- Although bacteria play a role in all forms of gingivitis, the primary cause of chronic gingivitis is inadequate oral hygiene.
- Risk factors
- Use of tobacco or ethanol is thought to be a risk factor.
- Immune incompetence is observed more frequently in HIV-infected children. As their CD4 counts decline, incidence of gingivitis may increase. Diabetes mellitus increases the risk of gingivitis and periodontitis.
- Drug-induced causes
- The list of drugs that cause gingivitis and gingival bleeding is extensive.
- Gingival bleeding may occur with the use of anticoagulants and fibrinolytic agents.
- Phenytoin, oral contraceptive agents, and calcium channel blockers may cause gingival hyperplasia.
- Gingivitis has been observed with use of protease inhibitors (eg, saquinavir, ritonavir), vitamin A and analogues, danazol, pentamidine, misoprostol, methotrexate, and gold compounds.
- Gingivostomatitis has been observed in exposure to arsenic, gold, bismuth, mercury, nickel, sulfur dioxide, lead, thallium, zinc, methyl violet, and topical chlorhexidine.
- Acute necrotizing ulcerative gingivitis
- Acute necrotizing infection may occur as a complication of chronic gingivitis in situations in which hygiene is abandoned completely or host defenses are weakened.
- ANUG is the result of soft tissue invasion by ubiquitous organisms and is not believed to be contagious.
- It is a risk wherever poor sanitation, diet, or oral hygiene is present.
- Living near livestock is an additional risk factor.
- Other causes
- Inadequate plaque removal
- Blood dyscrasias
- Allergic reactions
- Chronic debilitating disease
- Poor nutrition
- Lack of periodic dental examinations
