The role of vitamin D is explained by its numerous beneficial effects on systemic health. This publication examines the influence of vitamin D deficiency and the use of vitamin D on dental pathology and preventive dentistry. Vitamin D is a fat-soluble vitamin that exists in several forms, including vitamin D2 (ergocalciferol), primarily found in plant-based foods and mushrooms, and vitamin D3 (cholecalciferol or calcidiol), physiologically present in humans. Vitamin D3 participates in bone metabolism and numerous physiological processes in the body. Approximately 80–90% of vitamin D in humans is synthesized in the skin under the influence of ultraviolet sunlight, while smaller amounts are obtained through dietary intake such as fatty fish and egg yolk. Vitamin D2 from plant sources is absorbed in considerably lower quantities. Following hydroxylation, vitamin D3 is converted into its storage form, calcidiol, compensating for the absence of endogenous vitamin D synthesis in conditions of insufficient sun exposure. Depending on hydroxylation processes, vitamin D may exist in active or inactive forms, as well as in precursor states.
