Oral Microbial Flora in Health

Oral microbial flora pdf

Microbial flora in oral diseases.

The oral cavity being the hub of gamut of microbes, promotes the establishment of distinct microbial communities, such as on the mucosa and teeth. Metabolism of these organisms facilitates the attachment and growth of the subsequent colonisers. A delicate balance is maintained in the microbial ecosystem, with these organisms contributing to normal development and defences. However, any change o...

Normal Microbial Flora of Oral Cavity

INTRODUCTION The normal flora can be divided into two groups Resident flora and Transient. Some organisms are almost always present in a normal oral cavity and constitute constant/normal microbial flora. It is further divided into two types: indigenous & supplemental. Comprise of those species that are almost always present in high numbers (> 1%) in a particular site, such as the supra gingival...

Alterations in oral microbial flora induced by waterpipe tobacco smoking

Background Waterpipe smoking is a global health problem and a serious public concern. Little is known about the effects of waterpipe smoking on oral health. In the current study, we examined the alterations of oral microbial flora by waterpipe smoking. Methods One hundred adult healthy subjects (59 waterpipe smokers and 41 non-smokers) were recruited into the study. Swabs were taken from the ...

Microbial flora in carcinoma of oesophagus.

The microbial flora associated with carcinoma of the oesophagus was studied in 12 patients. Oesophageal mucosa was biopsied at thoracotomy and cultured under both aerobic and anaerobic conditions. A heavy mixed growth of aerobic and anaerobic organisms was obtained in all patients. One-third of isolates were anaerobic. The flora was of oral origin. The most appropriate antibiotic combination in...
