Active clinical trials for "Dental Caries"

Demineralisation and white-spot caries often occures during MB treatment. While resin infiltration has been proved to stop progression of enamel demineralisation, there is still a paucity of information in the literature concerning the best time point of infiltration: During or following MB treatment. Infiltration during treatment requires debonding respective brackets prior to infiltration, with subsequent re-bonding. In terms of preventing enamel damages by progression of demineralisation and enamel damages by de-bonding, it is unclear whether it was better to infiltrate enamel immediately, or to better postpone until completion of MB treatment. This study thus aimes to evaluate if resin infiltration can prevent enamel damage due to bracket de-bonding.

Today's increase of dentate elderly, many of them dependent, is a challenge, both according to the personal daily oral hygiene and dentistry. This is not only an oral problem, as research findings point to strong associations between oral and general health, even mortality. These findings are especially noticeable in elderly and frail individuals. Dental care is usually performed in stationary dental clinics where the patients are transported to receive treatment. Dependent elderly dental patients may present many obstacles to traditional dental care due to cognitive limitations or dementia, mobility or transport problems. An alternative is domiciliary dental care where the dental staff performs the treatment by a home visit, in the patients daily living environment. The ability to handle personal oral hygiene is often decreased in these patients and left to overburdened nursing staff that often also lack sufficient knowledge about oral health care, why prophylactic professional oral care is especially important. This type of care can with rather simple equipments be performed as domiciliary treatment of good quality, while more advanced dental care may present restrictions in the home environment. However, in the Swedish dental system with subsidized dental care for dependent and elderly patients, there are restrictions for the number of prophylactic oral care treatments. The levels vary in different counties and regions. The rationale for this is probably tradition and economy as scientific evidence is lacking. The aim with this project is to develop domiciliary professional oral care. The researchers will compare the effect of different regimens for domiciliary prophylactic professional oral care both according to content and frequency. The overall aim is to establish relevant recommendations for domiciliary prophylactic professional oral care.

Purpose: To evaluate the retention and caries preventive effect of the glass-ionomer fissure sealants and resin-based fissure sealant. Materials and Methods: Using a split mouth design ,a double blind randomized controlled clinical trial was conducted to compare the retention and the caries preventive effect of light cure resin base sealant (3M ESPE) and Glass ionomer sealant (FUJI). The study comprised of 120 government school children of 7-9 years age group. The glass-ionomer sealant and resin-based sealant were applied randomly on either side of the first mandibular permanent molars. They were recalled for assessment of sealant retention at intervals of 3, 6 and 12 months.

Dental caries is a multifactorial disease effecting majority of the human population.One of the etiological factor causing dental caries is salivary mutans streptococci. Reducing the levels of this bacteria in the saliva can significantly reduce the incidence of dental caries. A non-invasive intervention, such as the administration of probiotics reduced the salivary mutans streptococci levels.

The purpose of this study is to determine the effect of an educational intervention on mothers knowledge, attitudes and practices for preventing childhood caries.

AIM: To evaluate the efficacy of daily tooth brushing with high concentrated fluoride dentifrice on white spot lesion (WSL) formation in adolescents during treatment with fixed orthodontic appliances (FOA). The null hypothesis is that neither incidence nor severity of lesions would differ from a control group using standard fluoride dentifrice. SUBJECTS AND METHODS: 420 healthy consecutive 11-16 year-old patients referred to 4 Orthodontic Specialist Clinics are randomized to use either a dentifrice containing 5.000 ppm fluoride or a regular dentifrice with 1.450 ppm sodium fluoride. To be eligible for inclusion, the patients are scheduled for bimaxillary treatment with FOA for an expected duration of at least 1 year. All are instructed to use 0.25 gram dentifrice and brush their teeth during 2 minutes twice daily during the entire period of treatment. Before bonding, and after polishing with a rubber cup and non-fluoride pumice paste, 3 digital photos of the maxillary incisors, canines and premolars are taken. At debonding, remaining composite material on the surfaces is removed with a slow rotating carbide bur followed by polishing with a rubber cup and pumice paste. A new series of frontal and lateral digital photos is thereafter exposed. The primary outcome measure is the incidence and severity of WSL as registered separately by two blinded experienced and calibrated clinicians according to a validated index. A random sample of 50 cases is re-assessed to check intra- and inter-examiner reliability. The intervention is indended run throughout the full duration of the orthodontic treatment, varying between 18 and 24 months.

The study was designed to determine whether maternal xylitol consumption through regular chewing of xylitol gums can affect the salivary mutans streptococci (MS), dental caries, and dental plaque levels of their children.

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).

Fluoride toothpaste has been associated not only with declining dental caries prevalence but also with an increase in dental fluorosis. In the balance of benefits/risks of fluoride toothpaste use, the purpose of this study is to evaluate the availability of fluoride concentration in the mouth (biofilm fuild), as an indicator of fluoride benefits (anticaries effect), and the fluoride concentration in urine, as an indicator of fluoride absorption from ingested toothpastes (with potential to cause dental fluorosis), in a sample of young Brazilian children using toothpaste formulations representative of those available and most used by this age-group.

The purpose of the trial is to determine the extent to which daily use of xylitol lozenges reduces the appearance of new caries lesions in adults who tend to experience such lesions (i.e., caries-active adults).
