Active clinical trials for "Halitosis"

The Effect of Mouthwash Containing Green Tea With Aloe Vera and Chlorhexidine Mouthwash on Oral Malodour Among a Group of Egyptian Children: Randomized Clinical Trial

The primary aim of the current study was to determine the association between halitosis detection (presence or absence) and periodontal status in non-smoking subjects, and also assess whether halitosis recordings were related to periodontal clinical parameters, tongue coating and quantities of two putative periodontal pathogens on the posterior region of the tongue determined by real-time PCR. Secondary, halitosis recordings were compared among subjects with chronic periodontitis, chronic generalized gingivitis and periodontal health.

The B/B Checker, a new portable device for detecting odorous compounds in oral, exhaled, and nasal air, is now available. As a single unit, this device is capable of assessing several kinds of gases mixed with volatile sulfur compounds (VSCs) in addition to other odorous gasses. The purpose of the present study was to evaluate the effectiveness of the B/B Checker for detecting the malodor level of oral, exhaled, and nasal air.

The purpose of this study is to determine whether Lactobacillus reuteri-containing lozenges (Prodentis) are effective in treatment of halitosis in patients with chronic periodontitis.

Oral malodor is a common condition. In most cases this condition results from the proteolytic activity of anaerobic oral bacteria. These bacteria produce volatile sulfide compounds which are fowl smelling and are felt during exhalation and speech. the aim of the present study is to examine a simple method of detecting these bacteria in samples taken from the oral cavity of oral malodor patients.

Malodor production is bacterial in origin. The bacterial activity of anaerobic bacteria results in the breakdown of proteins and the production of foul smelling compounds. The aim of the study is to test the hypothesis that bacterial growth on dental implants contributes to malodor production and to see whether this contribution is associated with various properties of the dental implant such as: maker, type, depth ext.

Objective: determine whether there is a correlation between halitosis and mouth breathing in children. Study design: Fifty-five children between three and 14 years of age were divided into two groups (nasal and mouth breathing) for the assessment of halitosis. Descriptive analysis was carried out regarding the degree of halitosis in each group. The chi-square test was used for the comparison between groups, with 5% level of significance.

This study will assess the ability of a first prototype (strip) of a new chair side test to detect oral malodour. The strip is based on a new enzymatic reaction able to detect amines in saliva. Previous studies already showed significant correlations between oral malodor and the levels of amines in saliva. The limitation in their use as markers of oral malodour is the fact that the detection is usually carried out by complex techniques (High Performance Liquid Chromatography(HPLC)and Solid-Phase Micro Extraction-Gas Chromatography/Mass Spectrometry (SPME-GC/MS)). The results of the new enzymatic reaction can be evaluated by means of a colorimetric scale without necessity of extra apparatus. The study will be carried out with volunteers recruited at a multidisciplinary consultation for bad breath, organized at the University Hospital Leuven, Belgium. The paper strip will be used before the routine evaluation (organoleptic score (OS), the gold standard method for the diagnosis of halitosis and the level of volatile sulphur compounds (VSC), the most used adjunct tool to diagnose halitosis). The results of the new chair side test (strip) will be correlated with the OS and VSC measurements (OralChroma™, Halimeter®). The sensitivity, specificity and positive and negative predicted values of the new chair side test will be calculated. The cut-off values for a yes/no test will be determined. The meaning of color scores will be analyzed to assign a meaningful outcome to each score with relation to odor intensity.
