This study will be a cross-over single blinded clinical study to evaluate the in vitro fluoride release of three different brands of 5% NaF varnish. Subjects will be recruited at the University of Michigan School of Dentistry and will participate in a 15 minute clinical session at the beginning of each study arm, followed by 6 saliva collection recalls. During these sessions a fluoride varnish or placebo will be applied to their teeth, and subsequent salivary samples will be taken 1 hour, 4 hours, 6 hours, 24 hours, and 48 hours after the application. All subjects will receive 3 commercially available varnishes, and a placebo varnish. Between applications there will be a minimum of 2 weeks wash-out period. The goal of this study is to determine if different formulations of varnish lead to differing amounts of fluoride release. Despite their similar concentrations of NaF (5%), some in vitro data have suggested that they may differ in the amount of fluoride release. Determining fluoride release of these varnishes in vivo is important in assessing both the safety and efficacy of the product. Specific Aims 1. Determine the concentration of fluoride available in the oral cavity at different time periods after the application of three different 5% NaF varnishes as measured in unstimulated human saliva. 2. Compare the different patterns of fluoride release from each of the varnishes by comparing the fluoride concentration in saliva at corresponding time periods . 3. Evaluate the validity of an in vitro model used to measure fluoride release from varnishes. Percentage difference in fluoride release between the in vivo and in vitro data obtained from the same products will be compared.
The aim of this randomized clinical trial is to evaluate the effect of pH and fluoride concentration in liquid dentifrices in the control of dental caries in early childhood, in non-fluoridated area. This study also aims to assess the effect of the consistency of liquid dentifrices in the fluoride uptake in the plaque and the fluoride concentration in the toenails, to estimate the fluoride intake from these formulations.
An in situ model will be used to evaluate and compare enamel remineralization of human enamel specimens after single use of experimental children's toothpastes.
The purpose of this study is to determine if adding daily application of CPP-ACP containing paste for one year is superior to regular fluoride tooth brushing in preventing dental caries in high caries risk Thai preschool children.
Fluoride toothpaste has been associated not only with declining dental caries prevalence but also with an increase in dental fluorosis. In the balance of benefits/risks of fluoride toothpaste use, the purpose of this study is to evaluate the availability of fluoride concentration in the mouth (biofilm fuild), as an indicator of fluoride benefits (anticaries effect), and the fluoride concentration in urine, as an indicator of fluoride absorption from ingested toothpastes (with potential to cause dental fluorosis), in a sample of young Brazilian children using toothpaste formulations representative of those available and most used by this age-group.
Considering the widespread use of sodium fluoride (NaF) and monofluorophosphate (MFP) based toothpastes, the present study aim to evaluate F availability in saliva after use of the top-selling Brazilian toothpastes. In a blind, crossover clinical trial study, volunteers will brush their teeth with one of the following toothpastes: 1) non-fluoride toothpaste (negative control group); 2) NaF/silica based toothpaste 3)MFP/calcium carbonate based toothpaste. After brushing, a rinse with purified water will be performed. Unstimulated saliva will be collected before and up to 60 min after brushing. Ionic fluoride and total soluble fluoride (corresponding to the sum of fluoride as ion and as MFP) will be determined after acid treatment of salivary samples to hydrolyze MFP. Fluoride will be determined using an ion selective electrode.
The purpose of this study is to determine whether lesion infiltration is an effective management strategy to arrest early tooth decay.
The aim of this study was to determine whether rinsing with water or cleansing teeth after topical fluoride therapy affect the dental plaque pH.
The purpose of this study is to observe the effects of glass-ionomer cement (GIC) lining on risk of pulpal complications in deep occlusal cavities with resin-based restorations.
