Active clinical trials for "Dental Caries"

Dental caries is the most common chronic disease of childhood and is increasing in prevalence in children 2-5 years old. Racial and ethnic minority groups as well as economically disadvantaged individuals are affected the most by this health outcome. This study will test if a community-based multimodal intervention will reduce 2-year incidence of early childhood caries (ECC) in children aged 0-5 living in public housing developments. The intervention combines the components of motivational interviewing (counseling) delivered by dental health advocates, fluoride varnish application, oral health assessment and referral. The investigators hypothesize that the multimodal intervention with motivational interviewing will reduce ECC behavioral risk factors thereby leading to a reduction of ECC incidence when compared to fluoride varnish application, written oral health education materials and oral health assessment and referral.

The aim of this study was to investigate the buffering effect of a calcium glycerophosphate-fluoride (CaGP-F) dentifrice on in vivo dental biofilm after a cariogenic challenge and evaluate its probable 12-hour protective effect. Twelve young adults took part in this randomized, double blind, 14-day 4-phase crossover study. Between each phase, the volunteers had a 1-week wash-out period. Coded dentifrices were randomly assigned to the volunteers: A) no F and no CaGP; B) CaGP-only (0.13%); C) F-only (1500 ppm (ppm= parts per million of fluoride which is equivalent to mg/kg)); D) CaGP-F (0.13%, 1500 ppm, respectively). The pH measurements were taken from a single-site using a microelectrode, with salt bridge established by a 1M KCl (one molar potassium chloride) solution with a reference electrode. pH measurements were taken at 0 (baseline), 1, 7, 14 and 21 min (minutes) after a cariogenic challenge (10% w/v sucrose solution, %w/v = percent weight per volume). Four sets of measurements were carried out: (D0BS) before test dentifrice usage; (D01min) 1-min after test dentifrice usage; and (D712h) 7 days and (D1412h) 14 days using the test dentifrice, 12 hours (h)after brushing. Stephen curves and mean AUC (area under the curve) were obtained.

The goal of this study is to address the effectiveness of a modified cavity prevention protocol for 5-9 year-old children which emphasizes better diet modification, more frequent professional fluoride applications, and xylitol product usage based on individual risk status in a 1-year randomized controlled clinical trial in the University of California, San Francisco (UCSF) Tenderloin Community Pediatric Dental Clinic. The investigators hypothesize that the regimen will help to reduce new cavities in children who are at risk for dental cavities.

The propouse of this study is to evaluate some combined preventive measures, of easy application in children under 6 years old as education, brush teeth, fluoride free tooth paste,fluoridated tooth paste, professional cleaning and fluoride varnish application, to determine between three groups of differents combined preventive measures, wich one is better in reduting dental caries appearance. Hypothesis: Ho: Dental caries reduction percentage is larger or equal in the group with only prevention education and Professional cleaning, than in the groups intercepted with fluoride varnish or fluoride toothpaste. Ha: Dental caries reduction percentage is less in the group with only prevention education and Professional cleaning, than in the groups intercepted with fluoride varnish or fluoride toothpaste.

The purpose of this study is to evaluate the success rate of alternative treatment of deep carious lesions in asymptomatic primary teeth with no clinical nor radiographic signs of pulpal inflammation. The treatment includes leaving a thin layer of caries that is present near the pulp chamber and includes liner placement and tooth sealing. This alternative treatment is to be compared with the treatment provided today to these teeth, which includes complete removal of caries and probably includes pulpotomy and wide preparation of the tooth. The study also evaluates the cost-effectiveness of both methods of treatment of deep carious lesions.

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.

Target question is as the following one: Does the daily use of a fluoride-free, microcrystalline hydroxyap-atite (HAP) - containing test toothpaste have a non-inferior caries preventing effect in the permanent dentition compared to the regular use of a fluoride control toothpaste (1450 ppm F-) with proven caries preventive efficacy (Walsh et al. 2019)? This multicenter, non-inferiority clinical trial, randomized, double-blind, active-controlled design, two-armed study evaluates the hypothesis that the home regular use of a toothpaste containing microcrystalline hydroxylapatite (HAP) (test toothpaste) provides a caries preventive effect in adults aged 18-45 comparable to the caries preventive effect provided by the regular use of a fluoridated tooth paste (1450 ppm -F) (control toothpaste) over observation periods of max. 18 months. Caries development will be assessed according to the clinical criteria of the Decay Missing Filling Surface Index (DMFS).

Space maintainers are used to preserve the space after premature loss of teeth but they could effect some factors that play a role in caries formation. The research aimed to assess the impacts of removable and fixed space maintainers on the salivary pH, flow rate, and Streptococcus mutans, Lactobacillus carriage.

The primary objective of this trial is to investigate the effect of a symbiotic lozenge on dental caries in young children.

This double-blind RCT aimed to evaluate the effect of sugar-free snacks on caries risk in 6-9 years-old schoolchildren. Considering a 20% difference among groups, the number of subjects needed per group was set in 87. Two-hundred-seventy-one children at risk for caries measured through Cariogram were selected and randomly assigned to three groups consuming twice a day snacks containing Stevia or Maltitol or sugar for 42 days. Parents filled out a standardized questionnaire regarding personal, medical and oral behavioural information. Bleeding on probing, plaque pH and cariogenic microflora were assessed at baseline (t0), after 21 (t1) and 42 days of snacks' use (t2) and 120 days after the end of use (t3). Cariogram was also repeated at t2.
