Caries Transmission Prevention in Alaska Native Infants Clinical Trials Info presented on Clinical Trials Search isn't intended to be a substitute for certified health advice, travels to or treatment by using a genuine physician. We are not physicians. Always consult your dr. on Caries Transmission Prevention in Alaska Native Infants conditions. Clinical Trials Search.org is a site committed to listing clinical research studies in human subjects. Caries Transmission Prevention in Alaska Native Infants Clinical research trials and Caries Transmission Prevention in Alaska Native Infants health trials occur in hundreds of cities throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectivity of new drugs. The propose of the studies / undertakings is to resolve certain human health questions. Clinical trials are a popular means for physicians, government agencies, and private sector companies to locate treatments for all sorts of conditions, including Caries Transmission Prevention in Alaska Native Infants. Caries Transmission Prevention in Alaska Native Infants Clinical Trials and other clinical trials permit volunteers to acquire medical treatment choices before they are available to the masses. Some times the test subjects obtain professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Caries Transmission Prevention in Alaska Native Infants clinical trial. Participants oftentimes recieve the most expert healthcare available for their Caries Transmission Prevention in Alaska Native Infants condition. Hazards are a reality, however, and can include extra or frequent physician visits, health risks (potentially life-endangering), and/or the treatment being uneffective. Trials are federally governed with rigorous guidelines to protect clinical trials subjects.

Caries Transmission Prevention in Alaska Native Infants
For Condition: Dental Caries
Status: Recruiting
Sponsor(s): National Institute of Dental and Craniofacial Research (NIDCR) , an Alaska Native corporation in Alaska
Synopsis: The purpose of this study is to conduct a community based, randomized control trial to determine if the use of chlorhexidine mouth rinse and xylitol-sweetened chewing gum will reduce the vertical transmission of caries between Alaska Native mothers to their infants.
Details: Alaska Native children are disproportionately affected by early childhood caries, compared to all U.S children. Dental care needs for adults and children in rural Alaska far exceed the acute care and prevention resources available. As a result, there is a high level of dental morbidity present among adults that likely contributes to early transmission of mutans streptococci (MS) from adult caregivers to infants in the household. Furthermore, the cultural practice of pre-mastication of solid food for infant feeding amplifies the transmission of oral secretions from adult to child. The prevention of early MS acquisition and subsequent caries in infants and toddlers requires efforts starting at birth. Since Alaska Natives are a rural population at high risk for caries, interruption of vertical transmission of MS using a combination of improved oral hygiene practices, and topical antimicrobials and bacteriostatic agents may be an ideal prevention strategy for childhood caries. Chlorhexidine and xylitol are two agents that have been shown to reduce dental decay and MS counts. The specific aim of this proposal is to conduct a community based, randomized blinded trial to determine if the serial use of chlorhexidine and xylitol will reduce the vertical transmission of caries between Alaska Native mothers and infants. We hypothesize that a two week period of twice-daily chlorhexidine mouthwash use prior to delivery, followed by a subsequent two year period of maternal xylitol gum use, will lead to a significant reduction in the age-specific prevalence of early childhood caries at 12 and 24 months of age among the offspring of mothers in the intervention group, compared to control group mothers. We also hypothesize that, compared to controls, mothers and children in the intervention group will have significant reductions in oral MS counts at each follow-up interval. If proven successful, this intervention could have a significant impact on the prevalence of caries among young Alaska Native children and other population groups at high risk for childhood caries.
