Active clinical trials for "Dental Caries"

The aim of this proposed study is to investigate the cost-effectiveness of four methods in preventing fissure caries in permanent teeth, which is the most prevalent dental disease in primary school children in China. The four caries prevention methods are: resin fissure sealant, atraumatic restorative treatment (ART) sealant, sodium fluoride varnish, and silver diamine fluoride (SDF) solution. The specific study objectives are: to describe longitudinally the clinical outcomes of using the above four methods to prevent dental caries in the pits and fissures of permanent first molars in school children, to describe the cost of using the above four methods to prevent dental caries in an outreaching dental care programme in China, and to compare the cost-effectiveness of the above four caries prevention methods.

This study was conducted to assess the effects of commercially available probiotic drink on the number of salivary mutans streptococci in school going children, aged 12-14 years in Bangalore city in India

We hypothesize that oral hygiene habits in children 8-12 years of age can be improved using video format Social Story intervention techniques. The purpose of this study is to investigate the effectiveness of video format social stories used to inform and educate children and parents about proper dental hygiene technique over a 6 week intervention period. We will measure the success of intervention using data collected from clinical exams and caregiver/participant surveys. Evaluation of data collected will be used to determine the effectiveness of the intervention.

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.

This randomized clinical trial is aimed at testing the efficacy of pit and fissure sealants, in a current environmental context different from that of the seventies and eighties. It has a split mouth design. 4OO subjects are included and the duration of follow up is 2 years.

The objective is to conduct an RCT to evaluate the effectiveness of Licorice in comparison to standard caries preventive measures for the prevention of new carious lesions in high caries risk patients.

The aim of this study was to evaluate the long-term effectiveness of a lay health advisor (LHA) intervention on immigrant children's caries and preventive behaviors.This randomized controlled trial included mother-child pairs in the intervention group (IG) and a brochure-only control group (CG), respectively. The IG received a four-week one-on-one session by an LHA on caries-related knowledge and brushing techniques. Baseline and follow-up surveys were used to collect the data in caries experience and maternal caries preventive behavior.

The short-term effects of chewing gum containing xylitol and/or blackberry extract on oral microbiota was studied. Fifty healthy adults participated in a randomized, placebo-controlled, cross-over design study.

In Taiwan, the prevalence of sleep problems, myopia, and dental caries in school-age children is high. Little is known regarding the implementation of oral and vision health outcomes around bedtime. A bedtime routine intervention was conducted to improve children's oral, vision and sleep health.

The anticaries effect of fluoride is through the increase in fluoride presence and retention in the oral fluids, reducing dental demineralization and enhancing remineralization. Previous studies showed that a preapplication of calcium (in a rinse) prior to administration of fluoride greatly enhances fluoride concentration in the mouth and the anticaries effect of fluoride. The hypothesis of this study is that the same can be achieved by chewing a calcium supplement prior to a fluoride rinse. The first goal is to determine if chewing these calcium supplements will increase calcium concentration in the oral fluids above baseline levels. Secondly, the calcium supplement with the highest calcium release will be tested before a fluoride rinse to assess the increased retention of fluoride in the oral fluids when compared with the fluoride rinse alone. In both parts, healthy volunteers will participate and saliva will be collected to assess calcium and fluoride concentration.
