Comparative biophysical assessment of the influence of some extra-strong creams for fixation of removable dental dentures on the condition of tissues of the prosthetic field

Annotation. One of the main complaints of patients using removable dentures is their poor fixation in the oral cavity. To improve the fixation of removable dentures, adhesive creams are used, the use of which increases the functional value of the dentures and significantly accelerates adaptation to the dentures. The aim of the study was to compare the effectiveness of some adhesives in people using partial or complete removable plate dentures using spectrocolorimetric research of periodontal tissues in patients using denture fixation creams. The studies involved 75 volunteer patients (50 women and 25 men) aged 45 to 74 years, who used removable dentures made of acrylic plastic. The material for the study was modern fixing creams «Lacalut Fix Extra Strong Fixation», «Corega Extra», «Protefix Extra Strong». For the comparative evaluation of means for fixation of prostheses, biophysical studies were conducted, namely spectrocolorimetric assessment of the gums inflammation degree and spectrocolorimetric assessment of the functional state of the gums of the microcapillary channel. Statistical processing of the results was performed by the variational-statistical method of analysis using the STATISTICA 6.1 program. It was shown that in patients who used «Lacalut Fix Extra Strong Fixation» after 3 months, «negative hyperemia» of the gums to the regulated chewing load almost completely turned into «positive hyperemia», which was accompanied by increased bleeding in the gums, i.e. turned into a normal physiological reaction of periodontal tissues to chewing load. In the «Lacalut Fix Extra Strong Fixation» group after 3 months. the greatest improvement in the condition of the gums was observed (in the wavelength range of 460 nm, the light reflectance values increased by 1.36 times, and at a wavelength of 660 nm – by 1.34 times, which indicates a decrease in the barrier permeability of the gums and the degree of inflammation in them, respectively). The results obtained indicate the feasibility of using additional adhesive agents by patients with removable dentures, namely the cream «Lacalut Fix Extra Strong Fixation».
