Oral bacteria are considered to be associated with several systemic diseases. Recently, their association with inflammatory bowel disease (Crohn's disease and ulcerative colitis) and colorectal carcinoma has attracted much attention. In this mini-review, the association of oral bacteria with these diseases is briefly summarized. Fusobacterium nucleatum is known as a periodontopathic bacterium, ...

OBJECTIVE Determining the relationship between saliva's physicochemical properties, cariogenic microorganism count, facultative anaerobic and gram-negative bacteria based on caries' experience in young adults. MATERIALS AND METHODS Stimulated whole saliva was collected from 120 students aged 17 to 34 years old for analysing salivary flow rate, pH, calcium and phosphate ion concentration, lact...

The effects of bittern water (BW), obtained from the ocean floor, on cariogenic bacteria and saliva secretion were examined. Streptococcus mutans was mixed with BW for 1, 3, 5, 10, and 20 min to explore the bactericidal effects of BW against cariogenic bacteria. Bacterial viability was calculated by counting the number of colony-forming units on Brain Heart Infusion agar plates. The results ind...

This study investigated the presence of the black-pigmented bacteria Prevotella nigrescens and Prevotella intermedia, the non-black-pigmented bacteria Actinomyces spp and particularly the cariogenic pathogen Streptococcus mutans in the dental biofilms of patients with or without black extrinsic tooth stains, using the multiplex polymerase chain reaction (PCR) technique. Analysis of the dental b...

Polyphenols occurring in cocoa, coffee and tea can have a role in the prevention of cariogenic processes, due to their antibacterial action. Cocoa polyphenol pentamers significantly reduce biofilm formation and acid production by Streptococcus mutans and S. sanguinis. In the same way, trigonelline, caffeine and chlorogenic acid occurring in green and roasted coffee interfere with S. mutans adso...

We developed a novel bioluminescent assay for detection of pyrophosphate in polymerase chain reaction (PCR) product. The principle of this method is as follows: pyrophosphate released by PCR is converted to adenosine 5'-triphosphate (ATP) by pyruvate phosphate dikinase in the presence of the substrate pyruvate phosphate and the coenzyme adenosine 5'-monophosphate; subsequently, ATP concentratio...

BACKGROUND The correlation between knowledge of dental care knowledge and its practice varies among the different health professionals. AIM The aim of the following study is to assess the knowledge and practice of health workers in a private medical health facility on dental care. SUBJECTS AND METHODS A descriptive cross-sectional study was carried out on the health workers in Faith Medical...

Background The formation of biofilm on the tooth surface is a result of the process of colonization of cariogenic bacteria, especially Streptococcus mutans, the main responsible for cariogenic (acid production) of dental biofilms [1]. The removal and chemical control of dental biofilm with chlorhexidine digluconate 0.12% (CLX) has been the most effective antimicrobial agent of choice clinic. Ho...

Eighteen different infants' drinks from five manufacturers were examined for their carbohydrate, calcium, phosphorus and acid contents, and their attack on tooth mineral. Seven of the drinks were compared with nine varieties of adults' soft drinks, and demineralization was studied with and without the presence of a cariogenic oral streptococcus. The influence of the acids already in the drinks ...
