Abstract:

Leukoplakia of the oral mucosa (OM) is the most common potentially malignant

disease characterized by the appearance of white, non-erasable spots that have no alternative

clinical and histological diagnosis. The article presents modern concepts of the etiology,

pathogenesis, classification, clinical forms, diagnostics and treatment of leukoplakia.

Particular attention is paid to the issues of dysplasia and precancerous potential of the

disease. A review of modern approaches to therapy and dispensary observation of patients

with this disease is conducted.

Key words:

leukoplakia, oral mucosa, dysplasia, precancerous disease, treatment.

Introduction.

Trophic ulcers of the oral mucosa are increasingly common in young patients

worldwide. Often, secondary lesions of the vascular system or significant exacerbation of

somatic diseases were detected in this category of patients [1]. According to recent studies,

patients with trophic ulcers of the oral mucosa with the following characteristic features

currently pose a particular challenge: fairly rapid progression of trophic ulcers and high

resistance of trophic defects to standard treatment methods [2]. Often, the treatment of

trophic ulcers is difficult to conservative therapy, which led to the need for surgical excision

with subsequent therapy, frequent relapse.

The task of the dentist is to make an accurate diagnosis, determine the etiopathogenesis of

the disease and choose the optimal algorithm for diagnosing trophic ulcers of the oral

mucosa. The issue of improving the treatment of trophic ulcers of the oral cavity, as well as

the implementation of preventive measures, remains open [6]. This dissertation research was

conducted at the Tashkent State Dental Institute, in the department of therapeutic dentistry in

2022-2025.

The study involved 75 people, including 55 patients with trophic ulcers of the oral mucosa

and 20 healthy individuals without lesions of the oral mucosa. The study included people

aged 65-75 years, including 28 men and 27 women. The average age of the subjects was

69.4 ± 0.9 years.

Clinical examination of healthy patients diagnostics assessment began with the collection of

the following indicators were assessed: levels of IgA, IgM and IgG, as well as sIgA in saliva.

Note: Differences were considered reliable at a significance level of p<0.05

The obtained data indicate significant changes in the parameters of local immunity in

patients with trophic ulcers of the oral mucosa. Before treatment, there was a significant

decrease in the levels of sIgA, lysozyme, lactoferrin, defensins and phagocytic activity,

indicating the suppression of both specific and non-specific defense mechanisms. At the

same time, an increase in the concentrations of pro-inflammatory cytokines (IL-1β and TNF-

α), as well as immunoglobulins of classes G and M, was recorded, reflecting active

inflammation and immune reactivity of the mucous membrane.

After therapy, most of the indicators significantly approached the values ​ ​ ​ ​ of the

control group. An increase in the level of sIgA, restoration of lysozyme and phagocytosis

activity, a decrease in the levels of pro-inflammatory cytokines and normalization of the

content of immunoglobulins indicate the effectiveness of the treatment and the restoration of

the functional state of local immunity. Conclusions. Analyzing the obtained data, we can

conclude about the necessity of conducting microbiological and immunological examination

of the oral cavity in case of trophic ulcer, accurate since timely detection of dysbiosis in the

studied forms allows to differentiate the disease.
