Active clinical trials for "Dental Caries"

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.

Adult tooth decay is an infectious disease that afflicts the majority of Americans aged 55 and older and is the most common chronic disease at midlife with an ever growing economic toll. Despite the fact that specific bacteria cause tooth decay, no FDA-approved anti-microbial treatment for decay is available to the American dental professional. The Prevention of Adult Caries Study (PACS) is a study designed to evaluate the efficacy of a topical, temporary, 10% w/v chlorhexidine dental coating in reducing new decay in adult dental patients at risk for decay.

The purpose of this study is to determine whether dental disease patterns and transmissable bacteria that are known to cause a severe form of dental decay in young children can be reduced or eliminated by treating mothers and their young infants early on with Chlorhexidine and fluoride varnish applications, respectively as part of a comprehensive Prevention Management Model.

The purpose of this study is to compare the efficacy of fluoride varnish (FV) applied once or twice a year with counseling to counseling alone in preventing early childhood caries (ECC) (tooth decay in children under the age of five).

A nasal endotracheal tube (ETT) is routinely placed in children and a fiberoptic scope (FOS) is commonly used for this purpose. Resistance to the passage of ETT is frequently encountered as it is advanced over the FOS for placement into the trachea, since it gets hung up on structures of the laryngeal inlet. The aim of the investigators study performed on forty children divided in two groups was to study in the pediatric population, whether a 90° counterclockwise rotation (CCR) of the ETT prior to advancing through the larynx, by nasal approach, prevents it from getting hung up at the laryngeal inlet.

The purpose of this research study is to investigate the bacterial composition of plaque and saliva located in the mouth and associate that with risk factors that cause cavities.

The study will determine whether clinicians who use a diagnostic device treat suspicious occlusal carious lesions (SOCL) surgically more often, with the same frequency, or less frequently, than dentists not relying on a diagnostic device. The study will also determine -- among those SOCLs that are opened -- whether the proportion of lesions that extend into the dentin when dentists are using a diagnostic device is more than, the same, or less than when no device is used.

The study will compare the effectiveness of Duraphat® fluoride varnish in preventing any further dental decay among 3-4 year old children in nursery schools. It is important to ascertain the additional preventive value that fluoride varnish may provide when applied in conjunction with other preventive measures which form part of a national dental health improvement programme targeting children at risk from dental decay. 1600 children will be recruited into the study for 2 years.

Aim: To assess in vivo if the intake of yogurt containing Bifidobacterium animalis ssp. lactis DN- 1173010 probiotic for a period of 2 weeks affects the salivary levels or biofilms of mutans streptococci and the lactobacilli of patients undergoing orthodontic treatment. Methods: A crossover, double-blind, randomized and placebo controlled clinical trial will be performed with 26 volunteers during 4 periods. During periods 2 and 4 (2 weeks each) the volunteers will have a daily ingestion of yogurt containing probiotic or of control yogurt which did not contain probiotic. Periods 1 and 3 were run-in and wash-out periods of 1 and 4 weeks, respectively. Experimental samples of saliva and biofilm will be collected from each participant at the end of each phase. Mutans streptococci, lactobacilli, total aciduric microorganisms, Candida spp. and total cultivable microorganisms will be counted. The values before and after the treatment will be compared with Wilcoxon's test (p<0.05).

The purpose of this study is to compare the effects of two new family-based oral health promotion programs with the routine program in use earlier in Vantaa public dental service. The children born in 2008 were followed from their first visit to public dental service at the age of 6-12 months to their dental examination at the age of 2-2½ years. The outcome measures are the colonization of mutans streptococci in dental plaque, dental caries, and the oral health habits of two-year-olds.
