In this article it stressed that antimicrobial peptides, which is also called host defense peptides, are an evolutionarily conserved component of the innate immune response and are found among all classes of life. These said peptides are powerful, broad-spectrum antibiotics, which demonstrate potential as novel therapeutic agents. Antimicrobial peptides have been demonstrated to kill Gram negative and Gram positive bacteria that can be clearly seen under a usb-microscopes which includes strains that are resistant to conventional antibiotics according to scientists, mycobacteria alsoincluding Mycobacterium tuberculosis, envelopes viruses, fungi and even transformed or cancerous cells as they call it. Dissimilar the preponderance of conventional antibiotics it appears as though antimicrobial peptides may also have the ability to enhance immunity by functioning as immunomodulators. Antimicrobial peptides can be clearly seen under usb-microscopes.

Antimicrobial peptides are short proteins, by and large between twelve and fifty amino acids long, although larger proteins with similar properties such as lysozyme are often classified as antimicrobial peptides. These so called peptides include two or more positively charged residues provided by arginine, lysine or, in acidic environments, histidine, and a large proportion in general approximately fifty percent of hydrophobic residues. The lesser structures of these molecules follow 4 themes, including ?-helical, and ?-stranded due to the presence of two or more disulphide bonds, and ?-hairpin or loop due to the presence of a single disulphide bond and/or cyclization of the peptide chain, and extended. Many of these peptides are unstructured in free solution, and fold into their final configuration upon partitioning into biological membranes.

The ability to associate with membranes is a definitive feature of antimicrobial peptides although membrane permeabilisation is not necessary. These peptides have a variety of antimicrobial activities ranging from membrane permeabilization to action on a range of cytoplasmic targets. Dental caries or also described as tooth decay, as we all know is an transferable disease which damages the structures of our teeth. If left unprocessed, the disease can front to pain, tooth loss, infection, and, in severe cases, death. There is a lengthy history of dental caries; with evidence showing the disease was present in the Iron, Bronze, and Medieval ages but also preceding to the neolithic period. The major increases in the prevalence of caries have been associated with diet changes. Nowadays, it remains one of the most common diseases throughout the world. There are numerous ways to classify dental caries. Although the presentation may be at variance, the risk factors and development among dissimilar types of caries remain largely similar. At first, it may appear as a small chalky area but sooner or later develops into a large, brown cavitations. Despite the fact that sometimes caries may be seen directly, radiographs are frequently needed to inspect less visible areas of teeth and to judge the extent of obliteration. Tooth decay is caused by certain types of acid-producing bacteria that can be clearly seen under usb-microscopes, which cause damage in the presence of fermentable carbohydrates such as glucose, sucrose, and fructose. The resulting acidic levels in the mouth affect teeth because a tooth’s special mineral content causes it to be sensitive. And therefore research suggests two specific varieties of AMP’s, known as defenses and cathelicidins, have broad antimicrobial effects against both gram negative and positive oral bacteria.
