Streptococcus mutans

characteristics of Streptococcus mutans that enables them to be the main initiators of dental caries in human subjects. The human mouth contains hundreds of species of bacteria, some improve oral health while some do not. Streptococcus mutans is one of the worst of these bacteria. “Streptococcus mutans [does] have a prominent, well-documented role in caries etiology.”2 In this article we will discuss (a) the history of Streptococcus mutans, (b) how S. mutans gets into our mouth, (c) and how S.…

Stephoccocus Mutans Steptococcus mutans occurs in the pits, cervices, and fissures of the teeth. S. mutans is a specials of biofilm gram positive rod shaped bacteria that is commonly found in the oral cavity. The oral cavity is considered the “ideal environment” for the growth of microorganisms because it’s warm, moist and contains a constant flow of nutrients through saliva and food consumption (Loesche 1986). S. mutans generally consists of around thirty to sixty percent of all the bacteria in…

Results: This study compared the antimicrobial effect of two herbal oils (Coconut and Nigella sativa oil) versus Chlorhexidine gluconate 0.2 % as gold standard on 3 types of oral cariogenic microorganisms (Streptococcus mutans, Lactobacilli and Candida albicans) 1- Streptococcus mutans: The results of this study showed that coconut oil had a statistically significant higher inhibitory effect on SM with decrease in number of CFU from 500 to 40 and 53.7 and percentage of reduction 92%…

activity of the drug Tal Sindoor can be tested in 2 methods i.e. Gradient plate technique and Kirby-bauer method. Tal Sindoor has an effective anti-microbial activity against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Streptococcus mutans and Candida albicans. But K. pneumoniae and A. Baumannii are resistant to Tal Sindoor like they are with other…

Introduction: Coconut oil is basically edible oil obtained from drupe of Cocos nucifera. Coconut oil is one of the most easily available edible oil and is very economical and use in every house globally. Majorly coconut oil consist of triglycerols and fatty acids. Coconut oil contains about 90% saturated fatty acids. Of which lauric acid is the main component (47.5% by wt), followed by Myristic acid (18.1% by wt) and palmitic acid (8.8% by wt). Major triglycerols aretrilaurin…

cervical margins but also beneath bands and brackets. Therefore, decalcification seen around the orthodontic brackets and bands, in the form of white spot lesions, is a negative treatment sequelae seen in more than 50% of orthodontic patients.1 Streptococcus mutans is prime bacteria commonly associated with enamel demineralization followed by lactobacilli in the oral cavity.2,3 Orthodontic cements such as glass ionomer cements (GICs), zinc phosphate cements (ZPC) are…

HLTIN301C Assignment Q5a+b need answering 1. List and give a brief description of the four main groups of microorganisms. • Bacteria – A single celled organism that thrives in diverse environments. There are 5 groups that bacteria can be divided into (according to shape): bacilli, cocci, filamentous, spirilla and vibrio. Some are beneficially good for the body and others can be parasitic and produce toxins that can cause disease or death. • Fungi – A single celled or multicellular organism…

Orthodontic Force: A review of its adverse tissue reactions Abstract The possibility to save and rehabilitate a deteriorating dentition depends on position of the teeth within the alveolar process and on number of remaining teeth along with their periodontal status. When the balance between forces acting on the teeth and the confines of periodontal tissues gets disturbed, an unstable condition arises. It occurs either by mobility of teeth or reduction of the periodontium. Gingivitis is unlikely…

The objective of this lab was to isolate and identify an unknown Gram positive and Gram negative bacteria through the use of various microbiological techniques. The identification of the genus and species for the unknown culture should be obtained based on the characteristics for Gram positive and Gram negative bacteria. Bacteria are prokaryotic microorganisms that lack a nucleus and therefore all its genetic information is stored in the cytoplasm of the cell. The bacterial cell envelope…

Imagine being able to create almost anything displayed on our computer screen. Imagine having able to take any 2 dimensional images and create a 3 dimensional object. The only thing that limits us is our creativity. Well 3D printing allows just that! Invented by a man named Chuck Hall, 3D printing allows us to take a digital file from a computer and “print” a real life physical 3 dimensional object. So how does 3D printing work? A 3D printed object is built up one layer at a time from…
