Denture Plaque Microflora in Geriatric Inpatients and Maxillary Defect Patients

Abstract

There is growing public awareness of the importance of oral health in the elderly and in compromised hosts because dental and denture plaque are closely related to systemic diseases. This study supports the hypothesis that dentures might serve as potential reservoirs of organisms causing systemic infections.

Dry mouth and denture plaque microflora in complete denture and palatal obturator prosthesis wearers

“…Based on the present analysis results, the total number of colonising microorganisms is influenced not by the presence or absence of dry mouth, but by the type of prosthesis. The number of colonising microorganisms might be considerably influenced by poor oral hygiene because of physical or mental handicaps and the frequency of oral health self‐care. In this study, there were no participants with physical or mental handicaps such as hemiplegia or amentia.…”

“…However, pouring specific culture media into a denture or impression allows for examination of only particular microorganisms, such as Candida spp. Therefore, examination of microbial flora is performed using a swab or spatula. In terms of the sampling area, Kashiwabara et al .…”

In terms of the sampling area, Kashiwabara et al isolated an area (23.7 mm 2 ) at the centre of the palatal tissue surface of the maxillary denture using a vinyl sheet with a hole 10 .…”

In terms of the sampling area, Kashiwabara et al isolated an area (23.7 mm 2 ) at the centre of the palatal tissue surface of the maxillary denture using a vinyl sheet with a hole 10 . Although the distribution of microorganisms on the mucosal surfaces of dentures varied between different denture regions, it was bilaterally symmetrical 8,12 .…”

“…Kashiwabara et al reported that the prevalence of Staphylococcus spp. in denture plaque was 45% in palatal obturator prostheses 10 , which corresponds with our result. Staphylococcus spp.…”
