McGill University Study - Summary
A Clinical And Microbiological Evaluation
Of Denture Cleansers
For Geriatric Patients In Long Term Care Institutions
This study was undertaken to assess the efficacy between three denture
cleansers to reduce microorganisms (fungi and Streptococci mutans) on dentures
among a hospitalized geriatric population.
It is common knowledge that edentulous patients in long term care hospitals
cannot adequately brush or maintain their dentures due to disease and poor
dexterity. Studies have revealed that poor dental hygiene and Candida Albicans
infections are very common among elderly denture wearers. As well, nurses
in institutions are overburdened making it difficult for them to care for
their patient's dentures.
The importance of clean dentures in these patients is not to be underestimated.
Dentures containing debris, tartar and stain cause irritation and subsequent
tissue response. It was revealed that denture cleaning and plaque elimination
is a neglected function in most old age homes.
In this study, patients were assigned to three denture cleansers or water
(control group). Denture Brite was used initially overnight, following
this for 20 minutes each day. The soaking time for Polident Overnight and
Efferdent New Concentrated Blue Tablet was overnight. These established
periods were based on the manufacturer's instructions.
The results of this study revealed different levels of effectiveness between
cleansers depending on the type of microorganism. In a multivariate analysis,
including all study periods, a significant difference in the rank of fungi
count was noted. Dentures that received Denture Brite appeared to have significantly
greater reduction in the number of fungi than those with Efferdent. Denture
Brite and Polident, are effective against fungi in comparison to water.
It was also noted that there was a considerable reduction in the number
of microorganisms before and after the use of the cleansers when compared
with water. The use of denture cleansers appears to be "clinically" useful
in the reduction of microorganisms and significantly reduces the amount
of food, stain and plaque on the dentures.
