Active clinical trials for "Dental Caries"

The anticaries effect of professional fluoride application has been associated with the formation of calcium fluoride-like products ("CaF2") on dental surface, which may function as a slow release fluoride reservoir. Among professional fluoride products, fluoride gel and varnish are the most important, and have different soluble fluoride concentrations, pHs and vehicles. Although the concentration of fluoride formed on enamel after the use of both is similar, the retention of these reaction products is unknown. Also, it is unknown the capacity of these reservoirs to enhance dental biofilm fluid with fluoride. Moreover, the effect of the varnish application time on these parameters is unknown. Therefore, the aim of this study is to compare the capacity of fluoride gel and varnish to form fluoride reservoirs on enamel and increase dental biofilm fluid fluoride concentration with time. Rapid biofilm-forming individuals will be selected to participate and divided into 4 experimental groups: 1. Negative control: no treatment; 2. Varnish 4 hours: fluoride varnish will be applied and kept on teeth for 4 hours; 3. Varnish 24 h: fluoride varnish will be applied on teeth and kept for 24 h; and 4. Gel: Fluoride gel will be applied on teeth. Microbiopsies of enamel will be obtained by a microbiospy technique to assess fluoride concentration before, 7 and 28 days after the treatments. Dental biofilm will be collected before and 3, 7, 14 and 28 days after treatments. Fluoride concentration on enamel and in the biofilm fluid will be determined by an ion-specific electrode. Data will be analyzed statistically comparing the groups and collection times.

Orthodontic appliance causes increase in plaque accumulation, especially around brackets, wires and attachments. Advances in orthodontics in recent time have led to improved quality of appliance and treatment procedures ultimately resulting in improvised standard of patient care. These bacteria metabolize different kind of carbohydrates accumulated around orthodontic appliances and create acidic environment in the oral cavity leading to enamel demineralization around the brackets and white spot lesions. This study was carried out to evaluate and compare the efficacy of probiotic toothpaste and chlorhexidine mouthwash in patients undergoing orthodontic treatment with individuals who are not using them.

This was a block-randomized, controlled, open-label trial and was executed in two preschools in The Gambia. Fluoridated table salt (250 mg F/kg salt) was administered in daily communal preschool feeding. In total, 304 children in the test group and 137 children in the control group, aged 3 to 5 years were enrolled according to inclusion criteria (complete primary dentition and a parental or legal guardian informed consent). Mean difference of incidence of cavitated carious lesions (Δd3/4mft) after 12 months was the primary end point. The relative preventive dental caries effect was. Secondary end points were the difference of incidence of white spot lesions and the difference of incidence of total carious lesions.

Background: Children with congenital heart defects (CHD) are reported to have poorer oral health compared with healthy children. The aim of the present study was to evaluate the effect of an intensive oral health care program among children with CHD followed from infancy to the age of five years, by comparing their oral health status at five years with a control group of children with CHD who had not received the program. Methods: In this longitudinal study, children in western Norway with a need for lifelong follow-up due to congenital heart defects were invited to participate (n=119). Children born in 2008-2011 were offered a promotive oral health intervention program from infancy to the age of five years. The outcome measures for evaluating the intervention were dental caries prevalence, dental erosion, plaque index and gingival bleeding index. The data of the intervention group were compared with cross sectional oral health data of five year old controls with CHD born 2005-2007 (already published).

It is of clinical importance to arrest the development of approximal caries at an early stage. The potential for initial caries to develop into manifest lesions has motivated studies on the use of sealants to arrest the progression of caries on both occlusal and approximal tooth surfaces. Therefore, the aim of the present study was to follow-up and examine after 3.5 years, the efficacy of sealing caries-free or non-cavitated mesial surfaces of first permanent molars abutting lesions on the distal surfaces of second primary molars. The null hypothesis tested here was that preventive and therapeutic sealants do not prevent the development or slow the progression of dental caries over a period of 3.5 years in comparison to non-sealed control surfaces.

This study examines the effectiveness of school dental screening in promoting dental attendance and reducing untreated caries among primary schoolchildren in Riyadh, Saudi Arabia.

This cluster-randomized controlled community trial aimed to assess the efficacy and costs of fluoride varnish application for caries prevention in a high-risk population in South Africa.

To evaluate the effects of a clinically approved and commercially available iron oxide formulation Ferumoxytol (Feraheme®) to control cariogenic biofilms and enamel demineralization. This study will be testing topical application of Ferumoxytol extra-orally using a standard in situ biofilm demineralization model.

This application, BeReady2Smile, will promote dental health behavioral parenting strategies among parents by incorporating a behavioral program for their children. Parents use a multimedia coordinated oral health prevention intervention program to promote dental health targeted at parents of young children attending parenting education classes and families receiving home visiting services through Head Start. Once developed, BeReady2Smile will be field tested for usability and usefulness with a group of parents of young children. Parents will rate the level of support needed, confidence in the system, and ease of use at each stage in the development, initiation, and maintenance of the system.

The primary goal of the study is to compare the success rates of pulpal anesthesia (defined as ability to complete the intended dental procedure without the need for rescue anesthesia) between Kovanaze nasal mist and Articaine needle anesthesia.
