نقش بیوفیلم باکتریایی در پیامدهای بالینی ناشی از عفونت های دهان و دندان

Oral and dental diseases such as dental caries and gingivitis are common problems in human societies. The formation of biofilms is considered as a very important mechanism of disease by these bacteria. The present study is an overview of these infectious diseases and their bacterial etiology, the mechanism of formation and role of dental plaque biofilm in the development of these infections and vaccination against dental caries is a new research field for dealing with these oral-dental diseases. In the current review paper, relevant articles were collected at Science Direct, Google Scholar, and PubMed databases from 1995 to 2017 and reviewed over a period of 2 months. Articles related to the role of bacterial biofilms in oral and dental diseases were used to write this research. As a result of the review of articles, it was seen that bacteria are one of the main causes of oral and etiology infections. Although the formation of bacterial biofilm at the different dental and oral surfaces is not necessarily related to the disease, but the formation of biofilms is considered as a very important mechanism of disease by these bacteria. The dental plaque biofilm in health condition often consists of non-pathogenic bacteria and humans. However, the in pathogenic biofilms, the levels of acidogenic and aciduric bacteria have increased dramatically and, by creating a stable acidic environment, demineralization occurs more rapidly.
