Filter by:The Detroit Dental Health Project (DDHP)aims to promote oral health and reduce disparities within the community of low-income African-American children (0-5 years) and their main caregivers (14+ years), living in the City of Detroit. The driving theme of the Project is to identify determinants and design interventions to answer the following question: why do some low-income African-American children and their main caregivers have better oral health than others who live in the same community? The Project has 3 support cores, 4 research core projects and 1 pilot study. The Project has selected a multistage random sample of African-American families living in the poorest 39 Census Tracts in the City of Detroit. A total of 1,022 families were recruited and interviewed at a community center in Detroit during the year 2 (2002). We have collected data about the social characteristics of parents, families, and neighborhoods that are associated with disparities in oral health; lead levels in saliva and blood of the caregivers; and dietary intake. All these families will be recalled in the year 4 (2004) and year 6 (2006) for longitudinal data collection. We are currently developing a tailored multi-media educational intervention (Project #3), based on data collected in the first phase (2002). The educational intervention will be administered using a randomized controlled design in year 4 (2004). Additionally, the Project is evaluating the impact on access to dental care of a state-funded experiment on utilization where Medicaid children are managed like privately insured patients (Project #4).
A program of motivational interviewing plus enhanced community services in prevention of early childhood caries vs. enhanced community services alone for American Indian mothers and their children will reduce the childrens' decayed, missing, and filled tooth surfaces measure over a 3-year period.
This study aims to assess the overall effect of pH and fluoride concentration of liquid dentifrices in the control of children dental caries of a fluoridated area, through visual inspection and the quantitative light-induced fluorescence (QLF) method. Toenail F concentration of a subsample of the children enrolled will be evaluated, in order to assess F bioavailability from these formulations and the evaluation of the concentration of fluoride incorporated into the biofilm will be done 6 months after initiation of the dentifrices use.
This study questions the interest of fluoride varnish dental application in preventing tooth decay in a population of institutionalised elderly people.
Attention deficit and hyperactivity (ADHD) affect 6% of school-aged children. Few studies reported higher prevalence of caries and restorations among children with ADHD. Methylphenidate is the drug of choice to treat ADHD. according to the medical literature methylphenidate can cause xerostomia. Our study will investigate saliva parameters (such as quantity, bacteria in saliva, buffer capacity), oral hygiene and diet habits and their influence on caries among children with ADHD and among healthy children. Our hypothesis is: - Children with ADHD will have more caries. - Children with ADHD will have more detrimental oral hygiene and diet habits. - There will be a difference in the saliva parameters between children with ADHD and healthy children.
There is lack of clinical trials on pediatric dental sedation. The purpose of this study is to test (using a randomized controlled trial design) the hypothesis that young children behavior during dental treatment improves with oral midazolam sedation. A further aim of this study was is explore whether behavior also changes over sessions needed to dental treatment completion.
During the period of 2000-2003, 179 healthy, term infants with no previous signs of allergic disease were recruited and randomized to daily intake of cereals with or without the addition of Lactobacillus paracasei subspecies paracasei strain F19 (LF19) from 4-13 months of age. The effects of LF19 on gut microbial composition, infections, allergies, immunological development, growth and blood lipids were monitored. Of 179 included infants, 171 completed the study. The study product was well tolerated with no observed side effects. Compliance was excellent. In a follow-up study, the aim is to investigate the long-term effects of feeding LF19 during weaning on allergies, immune programming, overweight, gut microbial composition and oral health in 8-year old children. The investigators' primary outcome will be to determine whether daily intake of LF19 during weaning results in less eczema at 8 years of age, and if the preventive effect encompasses also respiratory allergies and immunoglobulin E (IgE) - sensitization. The long term effects on gut microbial composition, overweight and metabolic markers will be investigated. Furthermore, the possible preventive effects of LF19 on caries will be assessed.
The behaviour of 12 dental nurses seeing 600 nursery school children in East Scotland will be video-taped to determine the interaction patterns adopted by the staff in the application of a fluoride varnish to the surfaces of the child's teeth. The aim is to test the benefit of certain communication strategies used by the nurses to affect an efficient application controlling for nursery school site, age of child and experience of dental nurse.
The aim of this study was to investigate the buffering effect of a calcium glycerophosphate-fluoride (CaGP-F) dentifrice on in vivo dental biofilm after a cariogenic challenge and evaluate its probable 12-hour protective effect. Twelve young adults took part in this randomized, double blind, 14-day 4-phase crossover study. Between each phase, the volunteers had a 1-week wash-out period. Coded dentifrices were randomly assigned to the volunteers: A) no F and no CaGP; B) CaGP-only (0.13%); C) F-only (1500 ppm (ppm= parts per million of fluoride which is equivalent to mg/kg)); D) CaGP-F (0.13%, 1500 ppm, respectively). The pH measurements were taken from a single-site using a microelectrode, with salt bridge established by a 1M KCl (one molar potassium chloride) solution with a reference electrode. pH measurements were taken at 0 (baseline), 1, 7, 14 and 21 min (minutes) after a cariogenic challenge (10% w/v sucrose solution, %w/v = percent weight per volume). Four sets of measurements were carried out: (D0BS) before test dentifrice usage; (D01min) 1-min after test dentifrice usage; and (D712h) 7 days and (D1412h) 14 days using the test dentifrice, 12 hours (h)after brushing. Stephen curves and mean AUC (area under the curve) were obtained.
The purpose of this study was to document the reasons for placing the first restoration ("filling") on a previously un-restored surface in a permanent ("adult") tooth.
