The purpose of the work was to study the etiology and main etiopathological factors of the development of aggressive forms of periodontitis based on the analysis of additional pathogenetic aspects of mineral metabolism disorders according to modern literature. Materials and methods. The bibliosemantic method was used to clarify the state of the problem, study the analysis of the results of previous scientific research based on literature sources and electronic resources. Results. Periodontitis is the most widespread disease among all periodontal pathologies (chronic generalized periodontitis occurs in 90% of cases). Until recently, aggressive forms of periodontitis were not given due attention, since according to epidemiological studies by S. Renvert and M. Wikstom (1996), in the general structure of periodontal diseases, aggressive forms of periodontitis occur with a frequency of 5–10%. To understand the mechanisms of the development of aggressive forms of periodontitis, attention is paid to their development in children and adolescents. Clinical and radiological examinations of children and adolescents showed different frequency of aggressive forms of periodontitis (localized juvenile periodontitis and generalized juvenile periodontitis): in the USA – 2.27%, in Denmark – 0.1%, in Finland – 0.1%, in Nigeria – 0.8%, in Brazil – 0.3%, in England – 0.17%, in Chile – 0.32%. Studies have shown that aggressive forms of periodontitis are equally common in children and adolescents, regardless of gender. At the same time, localized juvenile periodontitis is 3 times more common in boys, not the same for girls. A new and rather promising vector of periodontology is the study of the role of juvenile changes in the bone skeleton on the development and course of periodontal diseases. The development of mineral metabolism disorders in aggressive forms of periodontitis in different age groups requires further study, while the data obtained by molecular geneticists become relevant for understanding the possible ways of research. Considering the fact that the jaw bones are a component of the skeleton, the strength of which can be affected by various exogenous and endogenous factors, in particular genetic ones, the main direction of searching for candidate sensitivity genes is conducted among the markers of bone metabolism disorders. Of many candidate genes that determine bone mineral density, the most well-known is the vitamin D receptor gene. Conclusion. The analysis of the available literature showed that the study of the role of mineral and bone metabolism disorders in the emergence and development of aggressive forms of periodontitis has a wide scientific perspective, and obtaining new data on the state of systemic regulatory factors and their effects on the local mechanisms of periodontal tissue damage will allow not only to improve the diagnosis of various forms, but also to increase the effectiveness of the treatment of this pathology
