To be used as a model in dental research, an animal must fulfil experimental needs and information on the composition and variation of its oral flora must be available. Only limited data are available on the indigenous oral bacterial flora of BALB/c mice. In this work, a total of 671 isolates from different sites (saliva, tongue, teeth, and mucosa) of the oral cavity of BALB/c mice were identified. Only 18 different species were isolated, which indicates the relative simplicity of the flora. The predominant species of the total cultivable flora were "Lactobacillus muritius" (38%), Staphylococcus aureus (37%), Streptococcus faecalis (8%), Staphylococcus sciuri (4%), and Escherichia coli (3%). The other species each represent less than 2% of the flora. "Lactobacillus murinus" is found in greater proportion on mucosa than in the other sites, Staph. aureus predominates in saliva, and Strep. faecalis was found in greater proportion in tooth samples. Statistical analyses, using the minimum percentage of similarity, indicate that there is some variation among the microflora of different mice but that this difference is smaller for mice from the same lot. These results set the basis for the study of the variations of the indigenous oral microflora of BALB/c mice under different conditions.

Radicular cysts are, most often, oral tissue cysts. The basis for their development are the remains of Hertwig's epithelial sheath, which is stimulated to proliferate by infectious agents, mostly periapical granuloma or pulp necrosis. The cyst contents can be liquid, either clear or milky-white, or thick and yellowish-caseous pus. Bacteriological and histopathological researches have shown that development of radicular cysts from periapical lesions is a consequence of penetration of normal bacterial flora of the oral cavity. Material and methods The study has bacteriologically examined contents of 50 radicular cysts. They were operated between 1993 and 1995 at the Department of Oral Surgery of the Outpatient Health Care Centre Banjaluka. Pathological substrate of the cyst was punctured by a sterile needle and bacteriologically examined at the Microbiological Laboratory of the Clinical Centre in Banjaluka. Discussion and conclusion Radicular cysts contents most often consisted of alpha-hemolytic streptococcus, Streptococcus pneumoniae, Staphyilococcus epidermidis, Streptococcus group B and alpha-hemolytic Streptococcus. It is concluded that normal oral cavity flora is present in the cysts contents the infection penetrated through the root canal to periapex, where, due to the course of time, radicular cyst develops from periapical granuloma.

Organ Systems

The human body contains about 1014 bacteria which usually colonise different parts of the body. The bacterial flora is important for a person’s health as well as normal functioning of tissue and organ systems. Bacteria are single celled organisms and are found on almost all surfaces of human body. They act in synergy with host immune mechanism and provide protection against various undesirable foreign invasions, especially in the oral cavity, where they exist in a diversified form which survive in a symbiotic relationship with the host. When there is a disturbance in this equilibrium due to various factors like trauma or tobacco smoking, betel nut chewing and alcohol intake, which makes the mucous membrane more permeable to invading microorganisms, these commensal bacterial species can become virulent and give rise to oral diseases ranging from dental caries to oral carcinoma. The effects of these bacteria can be either direct or indirect initiation of chronic inflammation, formation of procarcinogens that contribute to the development of oral carcinoma. This article focuses on the role of oral bacterial flora in initiation and progression of oral carcinogenesis. Various bacterial and fungal species associated with oral carcinoma and predominant bacterial species in oral cavity and oropharyngeal region along with measures to prevent their adverse effects are described.

Influence Of Ph

Dietary nitrate is metabolized to nitrite by bacterial flora on the posterior surface of the tongue leading to increased salivary nitrite concentrations. In the acidic environment in the stomach, nitrite forms nitrous acid, a potent nitro sating agent. The aim of this study was to examine the effects of dietary nitrate, pH and temperature on nitrate reduction in the human oral cavity. Nitrate reduction was monitored by nitrate reduction assay based on incubation of nitrate test solutions in the mouth. Results show that all investigated factors significantly influence the reduction of nitrate in the oral cavity. With increasing levels of nitrate the amounts of nitrite in reduction assay increased, but reduction ratio (NO2/NO3) decreased in this conditions. Influence of pH on nitrate reduction is specific and in line with nature of nitrite-producing bacteria. The greatest reduction activity of bacteria is at pH 8. Variations of temperature of the oral cavity due to outdoor conditions also influence its reduction activity which is twice lower in January than in July. .
