Systematic Review The effect of overnight storage conditions on complete denture colonization by Candida albicans and dimensional stability: A systematic review
Abstract
Statement of problem
Overnight
removal of complete dentures is recommended to reduce the incidence of
denture stomatitis. The effect of overnight storage conditions is
unclear.
Purpose
The
purpose of this systematic review was to assess the effect of overnight
storage conditions on complete denture colonization by Candida albicans and to explore the effect of overnight storage conditions on the dimensional stability of complete dentures.
Material and methods
Two
electronic databases were searched through to November 2018. The terms
“denture*”, “dental prosthes*”, “acrylic resin*”, “storage”,
“nighttime”, “overnight”, “wet”, “dry”, “water*”, and “solution” were
chosen. Articles meeting the inclusion criteria were selected. For both
research questions, studies that did not store the dentures overnight or
for a minimum of 8 hours were excluded. For the primary research
question, studies that were not randomized controlled studies or
comparative studies were excluded.
Results
The
database search strategy resulted in a total of 159 potential studies.
After screening titles and abstracts and applying the inclusion and
exclusion criteria, 6 studies were retrieved for a full-text assessment.
Hand searching was also performed. Four studies were included in the
systematic review for the primary research question. Three studies were
included for the secondary research question. A meta-analysis could not
be performed because of variation in study design.
Conclusions
Cleaning of dentures before overnight storage helps reduce C. albicans
colonization. If the dentures are not cleaned, the use of an alkaline
peroxide–based cleaning tablet should be considered. Alternately,
overnight dry storage is an option for reducing C. albicans
colonization, with clinically insignificant changes to the dimensions of
the complete denture. Storing dentures in water alone may promote C. albicans colonization.
