The bacterial flora of denture plaque

Abstract

This study was undertaken to clarify the proportional distribution of bacterial flora in denture plaque in order to decide whether relationship between Candida and onset of denture stomatitis could be shown or not.The results obtained were as follows:1) The bacterial flora in denture plaque was predominated by facultative Gram positive cocci and rods. The flora in denture plaque was similar to a large extent to that in dental plaque excepted for the percentage of anaerobes.2) The correlation between the degree of denture stomatitis and the viable counts of Candida could not be shown. The proportion of Candida in the total viable counts had a same tendency of that relationship. But positive correlation could be detected between the degree of denture stomatitis and the isolation frequency of Candida.3) The proportion of Candida in the total viable counts on full denture was significantly greater than that on partial denture (0.01<P<0.05).4) There was no major difference in the proportional distribution of flora between male and female or among the different age groups.
