Active clinical trials for "Halitosis"

Background: Herbal remedies can have the role of prevention and control of bad breath Since in the previous studies, therapeutic and antibacterial effect of green tea and peppermint had been proven .we studied and compared the effects of green tea and peppermint mouthwashes on halitosis. Materials and Methods: This single-blind clinical trial study with cross over design total of 88 volunteer dental students who complained bad breath and had organoleptic score (>= 2) and higher average test scores were enrolled. The students were divided randomly into two groups Green Tea - Peppermint were assigned. Organoleptic test in the baseline, on the 7 day, 14 and 21 measured after rinsing the mouthwashes .As well as the satisfaction of both plants on the last day was considered. Data analysis was performed using tests; Wilcoxon signed rank test, Mann Whithney u, GEE (Generalized Estimating Equation -ordinal logistic regression).

The aim of the proposed controlled clinical trial is to evaluate the effect of photodynamic therapy (PDT) on the formation of volatile sulfur compounds (VSCs) from coated tongue and its action on the severity of halitosis in adolescents using different treatment protocols. HYPOTHESIS - Null hypothesis: There is no change in halitosis following the use of photodynamic therapy. - Experimental hypothesis: There is a reduction in halitosis following the use of photodynamic therapy alone or in combination with a tongue scraper.

Halitosis, also known as bad breath, is a term used to define an unpleasant and foul odor that emanates from the mouth and may have local or systemic origin. This project aims to observe the presence of halitosis and to verify if the treatment with antimicrobial photodynamic therapy (aPDT) is effective against it. The investigators will select 45 students or UNINOVE employees, from 18 to 25 years old, with a diagnosis of halitosis, presenting sulfite (SH2) ≥ 112 ppb on gas chromatography. Patients will be randomly divided into 3 groups of 15, which will receive different treatments: Group 1: treatment with tongue scraper; Group 2: aPDT applied in the back region and middle third of the tongue; Group 3: combined treatment of tongue scraper and aPDT. For the aPDT we will use urucum manipulated in the concentration of 20% (Fórmula e Ação®) in spray, to be applied in sufficient quantity to cover the middle third and back of the tongue (5 sprinkles) for 5 minutes for incubation, associated with a LED (Valo Cordless Ultradent®). 6 points will be irradiated on the back of the tongue with a distance of 1 cm between the points, considering the halo of light scattering and effectiveness of aPDT. The apparatus shall be precalibrated at wavelength 440-480nm for 60 seconds per point, irradiance of 450mW/cm and the light shall be irradiated so that a halo of 2cm diameter is formed per point. The results of the halimetry will be compared before and immediately after the treatment, besides the microbiological analysis of the tongue coating, before and after the treatment. The normality of the data will be measured using the Shapiro-Wilk test, and in the case of normality the Variance Analysis (ANOVA) test will be applied, and in the case of non-parametric data, the Kruskal-Wallis test will be used. To analyze the results of each treatment in both periods of the study, the Wilcoxon test will be used.

Bad breath or halitosis is caused by specific gases originating from the mouth or the expired air. In most cases the pathology lies within the mouth and in this case receives the name pathologic halitosis of oral cause or oral malodor. The aim of this study is to evaluate the immediate (masking) and long term (therapeutic) effect of commercially available mouth rinses in the treatment of oral malodor. For this volunteers with oral malodor detected by organoleptic evaluation and confirmed by the increase level of sulphur compounds in their breath (VSC) will be asked to use a designated mouthwash. The breath parameters will be assessed at baseline and 15' after the first rinse (15 ml, during 1 minute) and over night at the end of a period of 3 weeks during which the volunteers rinsed twice a day (15 ml, 1 minute) with the assigned mouthwash. The short and long term effect of a stannous fluoride/amine fluoride/zinc rinse; a chlorhexidine/cetylpyridinium chloride/zinc product and a negative control(fluoride rinse and/or water) will be compared.

Halitosis is the term used to describe any unpleasant odor relative to expired air regardless of its source. The prevalence of halitosis in the population is approximately 30%, of which 80-90% of the cases originate in the oral cavity resulting from proteolytic degradation by gram negative anaerobic bacteria. Antimicrobial photodynamic therapy (aPDT) has been widely used and with very satisfactory results in the health sciences, it involves the use of a non-toxic dye, called photosensitizer (FS), and a light source of a specific wavelength in the presence of the oxygen in the medium. This interaction, is capable of creating toxic species that generate cell death. The advantages of this approach are to avoid resistance to target bacteria and damage to adjacent tissues as the antimicrobial effect is confined only to areas covered by the dye and irradiated by light acting on the target organism rapidly, depending on the dose of light energy and power output. The objective of this controlled clinical study is to verify the effect of aPDT in the treatment of halitosis by evaluating the formation of volatile sulfur compounds with gas chromatography and microbiological analysis before and after treatment. Will be included in this research young adults in the age group between 18 to 25 years with diagnosis of halitosis. The selected subjects will be divided into 3 groups, G1 aPDT, G2 Scraper and G3 aPDT and scraper. All subjects will be submitted to microbiological analysis and evaluation with Oral ChromaTM before, after treatment and followed up of 7, 14 and 30 days For the evaluation of the association of the categorical variables will be used Chi-square test and Fisher's Exact Test, to compare the means will be used tStudent test and Analysis of variance (ANOVA) and to analyze the correlation between the continuous variables will be applied the correlation test by Pearson. In the analyzes of the experimental differences in each group the Wilcoxon test will be used. For all analyzes a level of significance of 95% (p <0.05) will be considered.

Morning bad breath (MBB) is often an enduring upset; this double blind, crossover, randomized study aimed to evaluate the bad breath-suppressing of 3 commercially available mouth rinses (Mentadent Professional® 0.05%chlorhexidine (MPc), Meridol® Halitosis (MH) and CB12®) and a placebo on morning halitosis during a washout period of 1 week.

Users of Breezy candy will utilize the candy's abrasiveness to scrape tongue surface. The scraping action together with the release of compounds contained inside the abrasive microcapsules will result in significant reduction of oral halitosis.

This study is designed as a retrospective cohort study to evaluate the potential of diagnostic procedures in defining populations of patients self-reporting unexpected and uncontrollable episodes of body odor and/or halitosis. The cohort - generally healthy individuals who had underwent multiple diagnostic tests recommended by their physicians and had not been diagnosed with any known medical condition - expressed their interest in trying gastrointestinal and nutritional diagnostic tests offered by Biolab Medical Unit. Our retrospective analysis will determine if these tests were useful as potential screening tools for metabolic body odor and halitosis.

To evaluate: 1) Evaluate the efficacy of a regimen commercially available versus brush alone on established plaque and gingivitis on adolescents. The Group 1 will use the following procedure: Colgate Ultrasoft toothbrush, Colgate Total 12 toothpaste and Plax Mouthwash, and the other Group will use Colgate Ultrasoft toothbrush and Colgate Cavity Protection toothpaste; 2) The level of halitosis. Two calibrated and blinded examiners (Cohen Kappa 85%) will evaluate the gingival condition using the visible plaque indices, a simplified oral hygiene index - IHOS and gingival bleeding index, with the aid of a WHO probe. For the evaluation of halitosis levels, all individuals will respond to a questionnaire regarding personal data, general and oral health, which includes hygiene habits and received previous guidelines for the procedures to be performed in the second moment. At the next consultation, subjects will be assessed clinically for halitosis using the portable BreathAlert™ sulfide monitor (Tanita Corporation, Japan), in addition to the evaluation of the tongue flap index (ISL), pH and salivary flow. The evaluations will be in the following periods: baseline, 1, 3 and 6 months of brushing. Data will be submitted to descriptive statistical analysis to demonstrate the distributions frequency of biofilm indices and gingival bleeding. The differences in the criteria evaluated will be submitted to Fisher's exact test (α = 0.05) and their performance at different times will be evaluated by the Mann-Whitney test (α = 0.05).
