Microbial Biofilm Formation as a Dental-fouling Microorganisms Attachment Phenomenon in Oral Cavity Environment

Abstract

DMFP (Dental microbial fouling phenomenon) of OCE (oral cavity environment) was studied in the local dental labs. Multi-smears of mature supra gingival plaques were randomly collected from fifty persons in dental labs that had different cultures, ages, sex and different scientific levels. Rapid microbial identification method was used to identify of these multi-smears by using vitek-2 compact instrument. The most frequent and appearance species of bacteria was Pantoeae spp., then Klebsiella pneumonia.

Quantitative and qualitative profile of aerobic bacteria in the second mandibular molar free of caries and caries, based on a case–control study

“…K. rosea, K. kristinae , and L. mesenteroides ssp cremoris were also found to be more frequently associated with caries in the second molar of this study. These bacteria are considered a normal member of the dental microbial community in the oral cavity and have the ability to cause dental caries, as has been proven in 14 individuals suffering from acute profound caries [26]. K. rosea and K. kristinae have also isolated from dental caries by another study [27].…”

“…S. aureus was more frequently isolated from the second molar. It is normally found with high rate as supragingival plaque in various parts of the oral cavity, such as saliva and periodontal area [26]. The association of S. aureus with dental caries is also referenced in numerous other studies, including those in Iraq [27][28].…”
