Clinical features
The inflammatory process in stomatitis tends to progress rapidly. One of its characteristic features is the spread of the lesion to the palate.
The intensity of inflammatory changes directly depends on the presence of teeth: it is clinically proven that in edentulous areas of the jaw, inflammation is significantly less pronounced.
The main factors triggering the exacerbation of symptoms include:
- Temperature stimuli (consuming very hot or cold food).
- Chemical and mechanical factors (using various dental hygiene products).
Stomatitis as a bacterial complication
Stomatitis can develop as a secondary complication of viral infections, particularly chickenpox. In this case, it belongs to the group of non-specific (bacterial) complications.
The pathogenesis of this condition is associated with secondary microflora invasion. This occurs against the background of virus-induced immunosuppression and damage to the skin and mucous membranes. Along with stomatitis, this group of complications includes pyinflammatory diseases (abscesses, phlegmon, erysipelas, impetigo), purulent conjunctivitis, and respiratory tract lesions.
Severe oral cavity lesions in HIV infection
The gastrointestinal tract, which begins in the oral cavity, is the most vulnerable system in HIV infection. Mucosal lesions here are caused both by the direct damaging effect of the virus and by opportunistic infections.
The following forms of oral cavity lesions are characteristic of HIV infection:
- Candidal stomatitis (fungal infection).
- Aphthous stomatitis.
- Various vesiculobullous and ulcerative eruptions.
Against the background of profound immunodeficiency, neoplastic processes can develop in the oral cavity. Kaposi sarcoma can affect the mucous membranes, manifesting as purplish-red plaques and nodules with ulceration. HIV-associated lymphomas may also develop, carrying the risk of total gastrointestinal tract involvement from the oral cavity to the anus.
Ulcerative-necrotic changes as a marker of systemic pathology
Severe forms of inflammation accompanied by ulcerative-necrotic changes in the oral mucosa can be a local symptom of dangerous systemic conditions:
- Blood disorders: in addition to ulcers, pronounced bleeding upon probing of the gingival sulcus is observed in the oral cavity. These local signs are accompanied by a sharp deterioration in condition, skin pallor, and weakness. To prevent fatal hemorrhaging before any surgical procedures, a complete blood count and a hematologist consultation are strictly mandatory.
- Gastrointestinal pathologies: gastrointestinal tract diseases directly affect the state of the oral mucosa, tongue, and periodontal tissues, significantly worsening overall oral hygiene.
- HIV infection: the presence of ulcerative-necrotic changes or candidiasis combined with chronic generalized periodontitis, fever, weight loss, and chronic diarrhea is a direct indication for referring the patient to specialized facilities for HIV testing.
Complications of concomitant inflammatory periodontal diseases
Inflammatory processes in the oral cavity frequently involve periodontal tissues, which requires differential diagnosis and comprehensive treatment.
- Acute gingivitis resolves with complete recovery when the etiological factor is eliminated in a timely manner.
- Chronic gingivitis often acts as a pre-stage to a more severe complication—periodontitis.
Periodontitis is a chronic immune-mediated destructive inflammation of all periodontal tissues. The pathogenetic chain of this complication includes: marginal gingivitis $\rightarrow$ destruction of the dentogingival junction $\rightarrow$ formation of pathological periodontal pockets $\rightarrow$ tooth mobility and tooth loss.
To remember the symptom complex requiring HIV testing in severe mucosal lesions, use the acronym KLAP-DS: Kandidoz (Candidiasis), Likhoradka (Fever), Yazvenno-necroticheskie izmeneniya (Ulcerative-necrotic changes), Parodontit (Periodontitis [chronic generalized]), Diareya (Diarrhea [chronic]), Snizhenie massy tela (Weight loss).
Class and exam questions
Why does stomatitis present more mildly in edentulous jaw areas?
According to clinical observations, mucosal inflammatory changes are less intense in edentulous areas compared to areas where teeth are preserved.
Which factors most frequently provoke the exacerbation of stomatitis?
The inflammatory process rapidly exacerbates under the influence of temperature stimuli (consuming hot or cold food) and when using dental hygiene products.
In case of which mucosal changes should a patient be urgently referred for a blood test?
When ulcerative-necrotic lesions and pronounced bleeding upon probing are detected, a complete blood count must be performed to exclude blood disorders and prevent massive bleeding during interventions.
Which forms of stomatitis are most characteristic of HIV infection?
HIV-positive patients are frequently diagnosed with candidal and aphthous stomatitis, as well as specific vesiculobullous and ulcerative eruptions in the oral cavity.
