Evolutionarily determined morphological changes that predetermine periodontal disease

Abstract

Relevance. Depending on the researcher’s purpose, science can solve local and fundamental problems. Periodontists solve local problems conditioned by the patient complaints presented at a specific time. The fundamental problems of medicine, for example, the evolution/ reduction of organs and tissues, are considered, by the scientific community, a set of local problems formed under the influence of geographical, social and other factors. Progress in solving fundamental problems is insignificant, which is explained by the fallacy of the scientific knowledge formation within the framework of individual disciplines of physics, biology, etc. Materials and methods. The subject of the study is the dialectical unity of the biological fluid filtration direction and contamination of the deep periodontium by planktonic biota. The object of the study is hydrodynamic disturbances following a decrease in the consistency of proximal contacts as a cause of periodontitis. The study rested upon the logic of multidirectional evolutionarily determined changes in the conventional and proposed components of the periodontium.Results. The study presented the arguments evidencing the necessity to supplement the solid-state periodontal model proposed by N.N. Nesmeyanov (1905) with new components – biological fluid and biofilm.Conclusion. Based on the parallel fundamental processes of coevolutionary improvement of biofilm and reduction of skull bones, the study showed the unity of our views on the problem of the etiology of periodontitis with the views of V.N. Kopeikin.
