| Popis: | Though S. mutans, virulence, and pathogenesis are characterized, reports are limited to the status of its carriage and virulence in patients with oral cancer and prosthesis. In this present study, we investigated the pathogenic characteristics of twenty strains of S. mutans of healthy subjects, fifteen of prosthesis patients, and eleven from oral cancer. The putative virulence gene and other factors, such as the ability to adhere to the oral epithelial cells, production of glycan and lactic acid of these strains were examined. Few of representative isolates of each group were used to see their activity on oral cancer cell line using cell cytotoxicity assay. The isolation rate of S. mutans was significantly more in carcinoma than prosthesis patients and control health group. The production of glycan and latic acid was together high in those isolates derived from prosthesis patients and patients with cancer. Adherence ability of strains isolated from prosthesis patients and cancer patients with oral prosthesis were significantly higher, compared to one isolated from a healthy individual. From our study results, we conclude that prosthesis patients and cancer patients with prosthesis carried a high number of S. mutans in their oral cavities.This study report that prosthesis patients and cancer patients with prosthesis carried a high number of S. mutans in their oral cavities. However, the S mutans are commensals still they have the capability to raise the severity of disease condition due to their ability to produce glycan and lactic acid. In our study, we proved that the adherence to buccal epithelial cells was significantly increased in S. mutans isolates of prosthesis patients and cancer patients. These indicate that in prosthesis patients as well as in cancerous patient's microbes had more potential to cause infection and increase the severity. |
