Introduction

A large number of analytes diagnosis has been shown to be present in saliva, including steroids and HIV hormones1 antibody.2 For the past two decades, researchers in oral health have developed tools salivary diagnostics to monitor oral diseases (including periodontal disease), 3 4, and assessment5 risk for cavities. These range from advanced diagnostic analysis of genetic susceptibility in interleukin-1 (IL-1) alleles in genetic analysis of oral pathogens identified using lectin staining for caries risk assessment.6 Development Current diagnostic biomarkers (for genomic and proteomic approaches), in conjunction with technological developments in diagnostic saliva allow development of robust diagnostic tools for dentists to use in making clinical decisions and predict outcomes treatment. 7

Saliva

Whole saliva is a product of the glands of 3 major (parotid, submandibular, sublingual) and numerous minor glands (labial, buccal, lingual). unstimulated saliva is typically obtained as a patient to spit every 60 seconds or head bent forward, the patient's saliva can drain from the lower lip in the cylinder. For collection of saliva in the tube flow per unit time can be measured. When measuring volume is not necessary to saliva can be collected on cotton rolls, gauze or filter paper. For salivary gland function or evaluation when large amounts of saliva are needed for analysis, stimulated whole saliva is used. Collection method is the same as for unstimulated saliva.8

The stimuli are usually chewing paraffin or a strip of rubber washed. A gustatory stimulus is obtained by standard 2% citric acid applied directly on the tongue every 15-60 sec. Parotid saliva may be collected by aspiration of the opening of the duct with a micropipette. parotid saliva is the best collected with vacuum chamber Lashley (fig.1 and 2) 9

Submandibular and sublingual saliva can be collected by vein catheterization with a micropipette, but in practice this is both uncomfortable for patients and technically difficult, because the orifice of the duct is mobile and has a strong sphincter. Because of this, the alginate and silicone impression material is used to hold the collection tube. As an alternative and simple technique is to block the secretion of parotid glands with absorbent pads and collect saliva mixed submandibular and sublingual pipette from the floor of the mouth. The saliva glands lip and palate can be collected by the filter paper disk or a disk other synthetic materials.10 salivary flow is given in ml / min / gland. In terms of "rest" the flow of the parotid gland amounts to 0 to 0.1 ml / min. After stimulation Citric Acid is the range from 0.5 to 1.5 ml / min. Stimulated values below 0.3 ml / min are considered pathological. flow rates will be seen in conditions such as gingivitis, denture recent and dominant cholinergic activity in Parkinson's disease, poisoning, etc. Low values are found during the use of tricyclic

antidepressants, led after the disintegration caused by inflammation or irradiation and after a radical surgery. The effects are more dramatic in saliva because of the reabsorption of water increased in the resting state.

SIALOCHEMISTRY

The choice of laboratory tests should be based on alleged links with the transport processes within glandular (sodium), intra cellular synthesis (protein, amylase), and diffusion by plasma constituents (.
