The purpose of this work was study of influencing violations of the homeostasis systems (HS) of the oral cavity in persons needing removable dentures with the acryl basis, on the degree of adaptation to them.
Materials and methods of research. During 5 years there were examined 765 patients, needing dental prosthetics. There were examined indices of the oral cavity homeostasis violations, which could have affected quality of removable dentures.
While studying frequency of HS violation and estimation of disorder influence on the extent of adaptation to the denture the obtained results were formed into 2 groups: the persons with the clinical signs at the tunica mucosa of mouth (TMM), having violation of the most indices of HS, and without clinical displays with some most pronounced immune metabolic disorders.
Results of research and their discussion. In case of the pathological violations of separate HS it was revealed that the slowest adaptation to removable dentures was in persons with chronic candidiasis course — almost 3 month long. The persons with oligosialia had average habituation of more than 2.5 months. The presence of allergic signs in the oral cavity increased the habitiation term up to 2.5 months. The shift of microbiocenosis toward disbacteriosis side lengthened a period of adaptation till 2 months. High activity of LP and lowered reactivity also multiplied the terms of habituation to the removable dentures (by 14 and 16% correspondingly longer) than in persons with the normal indices. High proteolytic activity in the oral cavity testifying to the presence of acute inflammation was the reason for prolongation of adaptation period on the average up to 2 months.
Conclusion. The mechanism of disorders of adaptation to the removable dentures in case of HS derangements can be presented as follows: the decline of functional activity of salivary glands stipulates development of TMM dryness, leads to deficit in the oral cavity of biologically active substances, participating in the processes of maintenance of stable medium, to development of disbacteriosis.
