Saliva Cancer

Saliva Cancer
By knowing the advantages of saliva as a diagnostic fluid, in 1992, promoted the New York Academy of Sciences, a major conference to address this problem. The conference participants recommended the development of tests to measure more sensitive and specific, and to understand changes in the saliva by the therapy and drug abuse, endocrine function, systemic and oral diseases, genetic diseases, nutritional status, and changes due to age. The Conference was aware of the possible diagnosis of salivary research and successfully developed a saliva test is more sensitive and able to increase our understanding of the relationship between oral health to general health.
Can disconnect developed a new technique, and analyze all the proteins found in human saliva, not only to be solved. This technique is called "three-step peptide fractionation '[three-step peptide fractionation] that can describe a protein marker of oral cancer and other diseases in the oral cavity. This method was developed by Timothy Griffin et al, at the American Society of Biochemistry and Molecular Biology.
They examined saliva samples from four cancer patients and found more than 1000 human proteins, including cancer-causing proteins. They also separate the proteins from more than 30 species of bacteria that have never been found in saliva, and some of them also have links to cancer.
Chih-Ming Ho, a professor and several colleagues at UCLA Microsystems Laboratories developed a sensor that can be detected with the biomarkers in saliva samples with oral cancer. The sensors have a micro chip that was programmed to bind to certain proteins associated, and will generate a fluorescent signal when the molecules bind to each other.

Salivary Testing / Salivary Test

Saliva Introduction
Titanium and its alloys are widely used in dentistry as prosthetic appliances because of a high corrosion resistance and good biocompatibility. These valuable properties are caused by passive films that are rapidly formed in the body fluid environment [1-3]. Recently, mouth-rinses, toothpastes, and prophylactic agents containing fluoride are utilizing to prevent the dental caries. However, decreasing the corrosion resistance of titanium in solutions containing fluoride has been reported [4-12]. The corrosion behaviours are related to the concentration of fluoride and the surrounding environment Therefore, the surface reaction on titanium under the existence of fluoride is important to understand the corrosion and tarnish of titanium in oral environment. Recently the corrosion of titanium was suppressed in solutions containing fluoride and eugenol (Figure1).

Eugenol occurs widely as a component of essential oils and is a major constituent of clove oil. It has been used since at least the nineteenth century, primarily as a flavouring agent, in a variety of foods and pharmaceutical products, and as an analgesic in dental materials. Recently it has been used as inhibitor on the corrosion of stainless steel in phosphoric acid solution
