Oral lichen planus among patients from Lublin Region in relation to 25-hydroxy-vitamin D3 serum level.

INTRODUCTION AND OBJECTIVE: Lichen planus is a chronic inflammatory skin disease involving the mucous membrane of the oral cavity. It is postulated that different factors play a role in the occurrence of the disease and may activate the immune system, thus influencing the development of lichen planus. Vitamin D is a steroid prohormone with multiple systemic effects. OBJECTIVE: The aim of this study was to assess oral lichen planus against 25-hydroxy-vitamin D3 serum level. Vitamin D takes an active part in the pathogenesis of immunisation diseases, may have also a beneficial effect on oral health. MATERIAL AND METHODS: The clinical picture of lichen planus was analyzed according to the concentration of 25-hydroxy-vitamin D3. Patients were given a questionnaire interview which included questions about the co-existence of systemic diseases, subjective complaints, and information relating to the individual course of the disease. In the next stage of the study, patients were underwent a physical examination. Laboratory determinations of the concentration of 25-hydroxy-vitamin D3 were also performed. RESULTS: The mean vitamin D concentration in patients with lichen planus in the oral cavity was 14.37 ± 4.95 ng/ml. An insufficient level (10-30 ng/ml) was detected in 84.91% of the examined patients, whereas a deficiency (< 10 ng/ml) was observed in 15.09% of those patients. None of the analyzed patients had vitamin D level in the range of established clinical standards. A substantially lowered vitamin D level was found in patients reporting bleeding and pain of the gums. CONCLUSIONS: The study enhances relationship between reduced levels of vitamin D3 and lichen planus in patients with oral lesions. Thus, vitamin D3 control and supplementation may play an important role in the treatment of lichen planus.

Impact of nutrition on the condition of the oral mucosa and periodontium: A narrative review.

Diet and eating habits significantly affect health and quality of life. Various diets and food eliminations can lead to nutritional deficiencies and malnutrition. This article discusses the relationship between nutrition, nutritional deficiencies, and the condition of the periodontium and oral mucosa. An analysis of PubMed materials was conducted to assess the impact of nutrition on the condition of the oral mucosa and periodontium. We also considered dietary habits such as vegetarianism, the ketogenic diet, the Paleo diet, the Mediterranean diet, the Western diet, and intermittent fasting. Vitamin deficiencies, both watersoluble and fat-soluble, as well as macroand microelements, can manifest in the oral cavity, among others, as gingivitis and bleeding, recurrent aphthous stomatitis, enamel hypomineralization, cheilitis, angular cheilitis, halitosis, glossitis, lingual papillae atrophy, and stomatitis. Malnutrition does not cause periodontal disease, but it increases the risk of its occurrence and accelerates disease progression. Inadequate nutrition, combined with other predisposing factors, may contribute to an increased risk of oral cancer and the development of leukoplakia.

Differences in the morphological structure of the human tongue.

BACKGROUND: The tongue exhibits significant individual variability in terms of shape, color, and surface texture. Due to its location, it is easily accessible for medical examination, although often overlooked. This is due to the inadequate number of studies assessing the morphology of the tongue in the healthy population. Determining the range of normalcy allows for the definition of tongue pathology requiring further diagnostics. The aim of this study is to assess differences in the morphological structure of the tongue in healthy individuals based on existing literature. Morphological structure was evaluated in terms of volume, shape, color, coating, papillae, texture, and lingual tonsil. MATERIALS AND METHODS: PubMed and ResearchGate databases were included for a thorough analysis of morphological differences in tongue structure. RESULTS: Tongue volume stabilizes by the end of the second decade of life and is closely correlated with BMI. Among the shapes of the tongue, forms such as circular, ellipsoidal, hammer-shaped, in the shape of the letter U, V, or W can be distinguished, and the multitude of these terms results from the lack of a uniform classification. There is agreement regarding tongue color, with various shades of pink and white being the most commonly observed, while the presence of another color may indicate disease. The density and size of individual papillae depend on the region of the tongue, age, and the presence of systemic disease. Geographic tongue, hairy black tongue, and fissured tongue are states of papillae pathology. Fissuring of the tongue increases with age, and fissured tongue is more common in men. CONCLUSIONS: Differences in the morphological structure of the tongue provide significant information about the health status of each individual. It is necessary to be aware of the physiological changes occurring within the tongue for proper diagnosis.
