Effect of different frequencies of preventive maintenance

Similar to other streptococci, the cell wall of S. mutans is composed of multiple layers of peptidoglycan decorated with glycopolymers that are characterized by the presence of l-rhamnose. S. mutans is one of the eight species belonging to the mutans group of Streptococci which are differentiated based on their heterogenicity in their genomic structure. It was first discovered and named by J Kilian Clarke in 1924 which were isolated and identified from carious lesions. The group of "mutans streptococci" was described as the most important bacteria related to the formation of dental caries. Streptococcus mutans, although naturally present among the human oral microbiota, is the microbial species most strongly associated with carious lesions.

(serotypes d and g), and S. downei (serotype h) (11, Salivary mutans streptococci and lactobacilli were enumerated with chair-side kits at baseline and 1 day after the final ingestion. Results: A statistically significant reduction of the mutans streptococci levels was recorded after ingestion of the probiotic bacteria via the straw (p<0.05) and the tablets (p<0.01), which was in contrast to the placebo controls. Mutans streptococci are the most important bacteria associated with tooth decay. S. mutans , the microbial species most strongly associated with carious lesions, is naturally present in the human oral microbiota.

It was first discovered and named by J Kilian Clarke in 1924 which were isolated and identified from carious lesions. Streptococcus mutans are gram-positive cocci shaped bacteria. These facultative anaerobes are commonly found in the human oral cavity, and is a major contributor of tooth decay.

[ncbi.nlm.nih.gov] Although S. mutans and S. sobrinus can be distinguished by appropriate laboratory tests, these are expensive and time-consuming so it is not always practicable to identify down to the species level in large-scale epidemiological studies. Streptococcus mutans (בקיצור: S. mutans, בתעתיק לעברית: סטרפטוקוקוס מוטנס) הוא חיידק בעל תצורה נקדית-אליפטית במקצת, גראם-חיובי, אל-אווירני פקולטטיבי (שיכול לגדול בנוכחות חמצן או באווירה עניה בחמצן ועשירה בדו-תחמוצת הפחמן).
