12 Clinical Trials for Various Conditions
The objective of this study is to evaluate how well the study product, Crest Daily Whitening Serum, alleviates Xerostomia and perceived halitosis over 1 week of use.
This study is designed to evaluate the effect of an investigational lozenge with the enzyme polyphenol oxidase and green coffee extract in reducing and controlling intra-oral halitosis following immediate use and daily use of the lozenge over a one-week period.
The purpose of this study is to assess whether Aquamin®, a multi-mineral natural product from red marine algae, can help reduce halitosis when taken for 90 days.
Purpose: To investigate the short-term clinical effect of curcumin-containing toothpaste on halitosis as compared to placebo and to assess potential shifts in the composition of dental biofilm associated with the use of curcumin-containing toothpaste Participants: This clinical study will 30 adult participants under prophylactic or periodontal maintenance protocol. Procedures (methods): Participants will be included and throughout the protocol will not allow the use any other oral hygiene products except standard manual toothbrush and study toothpaste (either test -curcumin-containing or placebo). Additionally participants will be instructed to odiferous foods such as onions, garlic and spices. At each of the three examination sessions, Plaque Index (six sites, O'Leary) and volatile sulphur compounds (VSC) will be measured.
The advantage of self-ligating brackets on periodontal health has yet to be determined. In addition, the utilization of tongue scraping as an adjunct to traditional oral hygiene measures has yet to be studied in orthodontic patients. The aim of this study is to evaluate the effect of bracket type on plaque accumulation and also the impact of the appliance on oral malodor. In addition, the effect of tongue scraping on halitosis will be studied in patients undergoing orthodontic treatment. We hypothesize that self-ligating brackets will harbor less plaque than normal brackets, that tongue scraping will significantly decrease halitosis in patients undergoing orthodontic treatment and that patients with self-ligating brackets will exhibit less halitosis as measured by halimeter.
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 investigate the efficacy of an experimental dentifrice, containing 0.454 percent (%) stannous fluoride and 0.3% zinc chloride, to reduce oral malodor, compared to a marketed regular fluoride dentifrice after 3 weeks twice daily brushing in a population of clinically diagnosed gingivitis.
Malodor is a multifactorial condition with oral pathology representing the main culprit and the tongue being the first to second contributor to the malodor. Bacterial load can represent a quantifiable measure regardless of the original pathology. It is hypothesized that reduction in malodor can be represented by tongue changes both in appearance, bacterial and biofilm load reduction (measured by CFU and volatile gases measurement), organoleptic measurement and subjective improvement. Methods: A randomized controlled prospective study under IRB approval. Diagnostic criteria for enrollment and follow up were organoleptic test by 2 judges, halimeter reading, tongue colores changes HALT questionnaire and direct aerobic and anaerobic tongue cultures measured by CFU. Patients were treated with laser tongue debridement (LTD) with an Er,Cr:YSGG solid state laser has been shown to be effective in biofilm reduction.
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.
The purpose of this study is to evaluate the effects of consuming a probiotic on salivary, plaque, and tongue bacteria, as well as oral malodor (bad breath). Healthy volunteers will consume a probiotic powder, or a placebo powder, that is dissolved in water for 4 weeks.
The purpose of this study is to evaluate the safety and efficacy of a newly formulated foaming gel product on gingivitis and/or moderate periodontitis when used with or without the GLO Science accelerating device (GLO Device), compared to standard tooth brushing with antioxidant whitening toothpaste with or without flossing (split mouth design for control group). This is a 60-day randomized single blinded parallel group study. After 42 days, all use of interventional products were discontinued, and the participants returned to the clinical center at day 60 for final measurements. The primary outcomes assessed in this study were the differences in gingival index (GI) and bleeding on probing (BOP) from baseline to 42 \& 60 days. The secondary outcomes are tooth whitening, oral malodor, pocket depth and plaque amount. It is hypothesized that participants using the gingival health product with the GLO Device will experience greater reductions in GI \& BOP measurements than the control group, as well as participants using the gingival health product on a toothbrush alone.
The purpose of this study is to identify metabolic signatures associated with malodor conditions. The investigators will perform state-of-the art metabolomics tests and bioinformatic data mining to explore if conditions leading to malodor can be screened by metabolomic profiling of urine samples.
