Summary: | Introduction The theoretical researches conducted aimed at determining the mathematic relations of functional
dependence among three variable parameters: medium rugosity (Rz), the number of colony forming units (CFU)
and the medium thickness of fungal cell layer ( ) characterizing the formation and growth of Candida albicans
biofilm. Material and methods The influence of the finishing techniques was materialized by medium rugosity
(Rz) measured for each polished surface whereas the process of formation and growth of cellular biofilms was
highlighted by parameters (CFU) and ( ) whose values were determined by electronic microscopy SEM. The
functional dependence among the three variables taken into consideration: (Rz, UFC and ) in case of the nonnoble
dental alloy was solved by using Mathematica 8.0 programme. Results The analysis of real regression
surface shows that the observance of the interdependence relation between Rz, UFC and parameters shall
occur for values of Rz = 0.72...2.65 µm, to which shall correspond medium thicknesses of the cellular layer =
19.7…28.8 µm. Similarly, from the regression surface of the predictive values it results that the satisfaction of
the regression function shall occur for values of Rz = 0.98...2.47 µm, whereas for parameter we will have the
value interval: 17.8...23.6 µm. Conclusions For the samples of Kera N alloy under study, all theoretical values
obtained by predictive analysis for the variable parameters Rz, CFU and show that the finishing techniques
applied to the surfaces of metal components of prosthetic restorations shall exert their influence on the
formation and growth of Candida albicans biofilms. |
