Introduction. Gingival recession is a highly relevant and common dental pathology. The prevalence of recession ranges from 45,5 to 99,3 % in people of different ages, with the risk of gingival recession increasing with age. The true etiology of gingival recession, its components and the degree of their influence, jointly or separately; the influence of the environment and lifestyle on the development of pathology are poorly understood. In the literature, for example, there is no classification of etiological factors according to the degree of their influence as triggers of gingival recession. It is of scientific interest to study the causes of gingival recession, their systematisation and assessment of the degree of influence of each factor separately and together.The aim of the study is to develop a classification system of etiological factors taking into account their significance and degree of influence on the formation of gingival recessions.Materials and methods. Analysis of scientific literature, methods of classification and structuring; methods of decomposition, integration and determination of cause-and-effect relationships.Results. A model of classification of factors of the etiology of gingival recessions was proposed, elements of the structure of etiological factors of gingival recessions were determined by the degree of their influence on pathogenesis.Conclusion. Conclusions. The study and understanding of the etiology of gingival recessions allows the clinician to select a personalised treatment taking into account individual characteristics that influence the recession occurrence and its condition: congenital and acquired factors; living conditions, habits, level of hygiene, as well as other components that aggravate or compensate for the degree and level of complexity of any recession - single, multiple or generalised. It is advisable to continue the study of literature data to expand the classification and detail the structure of etiological factors.
