A Study on the Denture Plaque of Children

Abstract

In Pedodontics, denture type space retainers, plates and FKO are often set in the case of children for denture guidance. When they are examined at denture adjustment or re-call, denture plaque is seen to have accumulated on the fitting surface. There are numerous reports concerning the denture plaque in the case of adults, and some have reported that Candida species were frequently isolated from the denture surface. However there is no report concerning this in the case of children. Therefore isolation of Candida species from the denture plaque of children whose ages ranged 3 to 18 (mean 10 years 5 months old) was attempted, and the results were as follows,1) The rate of Candida isolation was 41%.2) Candida species isolated were C. albieans A (59.1 %), C. albicans B (13.6%), C. pseudotropicalis (4.5%), C. tropicalis (2.3%), C. glabrata (2.3%), C. guilliermondii (2.3%), C. parakrusei (2.3%).3) There was a significant correlation between age of the subjects and the rate of Candida isolation.4) The rate of Candida isolation from the subjects who wore dentures, plates or FKO for more than 12 months was significantly higher than that for those who wore them less than 12 months.5) There was no significant difference between each ratio of Candida isolation based on the sex of the subjects, location of denture, plate or FKO, the kind of resin, the period of denture wearing per day and frequency of denture cleaning.6) There was a high correlation between denture plaque accumulation and number of colonies. However there was no correlation between denture plaque accumulation and the degree of redness of the mucosa under the denture, and between the number of colonies and the degree of redness.
