Active clinical trials for "Dental Caries"

he study was designed as a double-blind three-parallel-group randomized controlled trial, in which the evaluators and a researcher, not involved in the evaluation process, was responsible for the randomization process, were masked to the group assignment. The study will be carried out at 2 schools of the Metropolitan Area of Buenos Aires where school programs are developed by the Department of Preventive and Community Dentistry of the University of Buenos Aires, and that present homogeneous characteristics in terms of social risk. The children (n=244) attending those primary schools will be the population object of the trial. Clinical examinations Each child will go under a clinical examination to determine dental status according to the ICDAS II criteria (Pitts, 2005) and the Caries Treatment Need Index (CTNI). Intervention Children will be divided into three different groups according to the mode of treatment: NaF varnish group (NaFV) Professional application of 5% NaF varnish twice a year pH 7 (ClinPro White Varnish®) according to manufacturer's instructions. APF in tray Group (APFt) Professional application of APF 1.23% twice a year pH 3.5 (Klepp®) with tray according to manufacturer's instructions APF in toothbrush group (APFtbru) Professional application of APF 1.23% twice a year pH 3.5 (Klepp®) with toothbrush 2 minutes brushing according to manufacturer's instructions. Dental examination and Monitoring Observations and clinical examinations will be conducted at schools. After 12 and 24 months, the clinical examination will be repeated to assess the dental status of schoolchildren following the same criteria described. The presence of new caries lesions will be taken as a dependent variable. So sound surfaces on baseline will be observed for 24 months.

The purpose of this study is to determine whether a novel material of S-PRG fillers containing in a daily-used resin denture base and their capability of fluoride release and recharge to elevate the salivary fluoride level and prevent dental caries in Thai middle-aged patients between 35-60 years of age who wear the resin denture.

Triple-blind randomized controlled trial with two parallel arms conducted between 2012 and 2014. Children 2-3 years old, from 28 rural public preschools, located in low socioeconomic areas of Chile were invited to participate. Oral health education component was given to children, parents and educators, twice yearly. A new toothbrush and toothpaste for each child was delivered to the parents at baseline and in each of the follow-up visits. The experimental group was treated with fluoride varnish every six months while the control group received placebo applications. 277 preschoolers (2 to 3 years) Main outcome: Number of Caries Incident Cases, increment dmft index

The aim of this study is to evaluate the 18-month clinical performance of a multimode adhesive (Scotchbond Universal Adhesive, 3M ESPE, St Paul, MN, USA) in primary molars after partial carious removal. This randomized clinical trial will include subjects (5-10 year-old children) selected at two university centers (UFSM and FOUSP). The sample will consist of 132 primary molars presenting active cavitated carious lesions (with radiographic involvement of the outer half of the dentin), located on the occlusal and occlusal-proximal surface. The sample will be randomly divided into two groups according to bonding approach: etch-and-rinse or self-etch strategy. The restorations will be clinically followed every 6 months for up to 18 months using the USPHS modified criteria for clinical evaluation. Survival estimates for restoration longevity will be evaluated using the Kaplan-Meier method.

Calcium hydroxide and mineral trioxide aggregate have been used in vital pulp therapy with variable outcomes recorded by different study. They will be compared when used for direct pulp capping in cariously exposed mature permanent teeth.

Successful restoration of cavities in primary molars can be considered challenging. It is different from restoring cavities in permanent molars because factors such as the level of co-operation of the child and the handling properties and setting time of the restorative material will have some influence on the success rate of the restoration. The ideal requirements that a filling material should possess include that it bears the occlusal force, withstands the acidic and bacterial attack, survives in the oral environment in addition to being biocompatible with the oral tissues. In an attempt to achieve this idealism, a new class of restorative materials known as "bioactive materials" has been developed. The concept of bioactive materials was introduced in 1969 and later defined as "one that elicits a specific biological response at the interface of the material which results in the formation of a bond between tissues and the material." An example of bioactive materials is ACTIVA™ BioACTIVE (Pulpdent, USA). These materials are ionic composite resins which combine the biocompatibility, chemical bond and the ability to release fluoride of glass ionomers with the mechanical properties, esthetic and durability of composite resins. Compomer is widely accepted as a standard restorative material for primary dentition for Class I and II cavities. Its range of success rate in Class II restorations in primary molars is 78-96%. Many randomized clinical trials have reported comparable clinical performance to composite resin with respect to color matching, marginal discoloration, anatomical form, marginal integrity and secondary caries. In comparison to glass ionomer and Resin Modified Glass Ionomer, compomers tend to have better physical properties in the primary dentition. However, their cariostatic properties didn't differ significantly from those materials.

Caries prevalence in the Dominican Republic (DR) seems high, although recent information is lacking. In DR there is a growth and development program for all children from the age of 0 to 5.Even though there is a mandatory educational health program for children and parents in this program, where periodically pediatricians examine them, this program does not include oral health education/prevention. Thus, it is proposed A) to devise materials to be used by pediatricians to share relevant information about caries control to parents of toddlers, and B) to evaluate the impact of such material on caries prevention for groups of toddlers over a 1.5-year period. Educational material will be developed for parents, and the pediatricians will deliver this material to 10-months-old children randomly selected at Plaza de la Salud Hospital. The PI will train the pediatricians in caries prevention and how to deliver the information to the parents in a clear manner. A total of 306 will be allocated into two groups. The experimental group (128 children) will receive the devised educational materials at 10 months, follow-up information will be provided at growth and development visits when the child is 18-, and 24 months old. The second group will be considered as the control group and will not receive any educational materials (178 children). All the enrolled children will receive fluoride containing toothpaste and tooth brushes. After 18 months when the children will be about 3 years old they will be examined to assess dental caries status. A sample mortality rate of 40% is expected during the two-year follow-up. Differences in caries status between the two groups will be examined using Welch's independent t-tests for unequal variances.

The aim of the study is to determine the fluoride availability in saliva and dental biofilm after the use of increasing amounts of fluoride toothpaste. Using a crossover and blind design, 15 children (18-42 months old) had their teeth brushed with increasing amounts of fluoride toothpaste. Fluoride concentration in saliva and dental biofilm was determined up to 30 min after brushing.

The aim of this clinical study is to compare and evaluate the Success of Selective Caries vs Stepwise Caries Removal Techniques in treatment of dental caries.

This clinical trial will be conducted to compare the clinical performance of self adhesive giomer containing flowable composite and putty nanohybrid resin composite in class V cavities over one year follow-up
