Bad breath is considered a major cause of visits to the dentist, only surpassed by caries and periodontal disease. In most cases, halitosis has intraoral etiology, by having numerous microenvironments that harbor bacteria and provide features which facilitate their proteolytic activity and putrefativa. The back of the tongue is considered one of the primary sources of bad breath, both for patients with periodontal disease, and for the healthy. The large area of the lingual surface for presenting becomes irregular, fissured and has a papillary structure capable of retaining large quantities of substrates, there is shown an excellent site for the growth of microorganisms as compared to other areas smaller gifts in the mouth. mechanical procedures are commonly used to remove tongue coating with favorable effects in decreasing halitosis. Thus, the aim of this project is to evaluate a new technique of lingual hygiene 'technique of X' and its effects on the breath and the amount of microorganisms present in the language, according to different diagnostic features of breath and microbiological parameters. Initially, the breath of each patient will be classified by organoleptic measurements (ORL) and self-assessment indicated on a Visual Analogue Scale (VAS) to then be collected coating samples from the tongue dorsum. Patients will receive instruction on the tongue brushing technique 'technique of X' (test groups) and after 15 consecutive days of systematic mechanical cleaning of the tongue dorsum (twice daily), new analysis of breath and tongue coating collection will be held for comparing the data relating to the effects of the technique in relation to breath and amount of microorganisms. Once the 'Technical X' has proven its effectiveness, can contribute to improve the quality of oral hygiene in addition to acting directly on reducing the population of halitosis levels, since it is a simple and affordable technique.
