Filter by: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.
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 investigators propose a novel assessment of oral malodor (halitosis) by a quality of life (QOL) questionnaire designed specifically for halitosis and a new treatment for halitosis by improvement of mouth dryness.
The purpose of this study is to determine effect of Mouthwash containing Camellia sinensis extracts on oral malodor and gingival inflammation in gingivitis subjects.
Medical center personnel were screened organoleptically for bad breath by 2 investigators using Rosenberg scale 0-5, and measurement of breath sample in portable gas chromatograph. With a threshold score of 2 or more, or 75parts per billion(ppb) hydrogen sulfide(H2S), subjects invited to enter clinical trial of the mechanical effect of daily tongue scraping with the adjunctive use of 0.12% chlorhexidine gluconate mouthwash or 0.1% stabilized chlorine dioxide mouthwash. Subjects randomly assigned in double-blind trial for one week. The null hypothesis is there will be no difference between the two rinses as adjuncts to tongue scraping.
Previous research has shown the oxidizing properties and microbiological efficacies of chlorine dioxide (ClO2). However, no clinical studies have investigated its microbiological efficacies on periodontal and malodorous bacteria. The aim of this study was to assess the inhibitory effects of a mouthwash containing ClO2 on morning oral malodor and on salivary periodontal and malodorous bacteria using for 7 days.
A mouthwash containing chlorine dioxide would be effective to reduce oral malodor.
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.
the use of a herbal formulation containing sage, echinacea,lavender and mastic gum would prevent oral malodor if delivered in an appropriate delivery system to enable slow release of the active ingredients.
