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.
