| Summary: | Introduction: A large number of microorganisms invade the oral
cavity and others live there. Those with greater pathogenicity, such as
the fungus Candida albicans, are usually associated with sub-prosthesis
stomatitis.
Objective: To evaluate the level of Candida colonization in heat-
cured acrylic and Valplast system used as dental prosthesis bases.
Material and Methods: An observational, quasi-experimental study
was carried out on a sample of 15 heat-cured acrylic plates and 15
Valplast system plates, subjected to contact with Candida albicans, which
was activated in sabouraud agar, in a sterile environment and with the
temperature conditions of oral cavity at 37 °C, for 48 hours.
Results: There is an important difference between the polished
valplast surfaces, observing a lower amount of CFU/ml compared
to thermo-cured acrylic. The unpolished heat-cured acrylic surfaces
outperformed the Valplast system with values greater than 100,000
CFU/ml. The level of colonization by this microorganism in thermo-
cured acrylic and Valplast system denoted the existence of differences
between the CFU/ml values and the groups of materials with polished
and unpolished surfaces of thermo-cured acrylic and Valplast system,
being less for this latest material.
Conclusions: The colonization levels of Cándida albicans are lower
for the Valplast system, compared to the thermo-cured acrylic ones, so
the latter material has a greater capacity for the formation of biofilms of
this fungus and a greater risk of producing Candidiasis on both polished
or unpolished surfaces. |
