7 Clinical Trials for Various Conditions
The researchers are doing this study to find out more about what may lead to the loss of tooth enamel (the thin outer covering of the tooth) and how often it happens in people with esophagogastric cancer, colorectal cancer, pancreatic cancer, breast cancer, head and neck cancer, or non-small cell lung cancer, or a healthy volunteer.
The purpose of this study is to investigate the ability of an experimental dentifrice containing 1150 parts per million (ppm) fluoride to remineralize acid-softened dental enamel and help prevent further demineralization compared to a 0 ppm fluoride placebo dentifrice and a marketed, fluoride-containing dentifrice (Reference Dentifrice).
This will be a randomized, controlled, single center, single- blind, 3 period, 3 treatment, cross-over, in situ design which consists of placing pre-eroded bovine enamel specimens intra orally using a palatal appliance and testing the remineralizing performance of the experimental (dentifrice containing 0.254 Percent weight by weight \[%, w/w\] sodium fluoride (1150 parts per million \[ppm\] fluoride) and 5% KNO3 \[potassium nitrate\]), comparator (dentifrice containing 0.454% w/w stannous fluoride (1100 ppm fluoride) and placebo (Fluoride free placebo containing 5% KNO3 \[0 ppm fluoride\] ) dentifrices 2 and 4 hours (hrs) post treatment application, based on surface micro hardness measurements. This study will be carried out in healthy adults with a maxillary dental arch suitable for the retention of the palatal appliance.
An in situ model will be used to evaluate and compare enamel remineralization of bovine enamel specimens.
This study focuses on assessing dental caries, erosive tooth wear, and fluorosis in primary teeth using a 3D intraoral digital scanner. The investigator will validate findings using three key indices: ICDAS (for caries), BEWE (for erosive wear), and TF (for fluorosis). Teeth will be cleaned and examined visually using dental tools and light. After visual checks, teeth will be scanned with a 3D intraoral scanner. Children aged 3-12 years with fully erupted primary teeth, seeking dental treatment at the Department of Pediatric Dentistry, Indiana University School of Dentistry. The visual examination and digital scanning will be performed just once and during the dental appointment at the clinic of Pediatric Dentistry following the protocols used in the clinical routine. It is expected to complete the visual examination and the digital scanning in 30 minutes.
This study aims to assess the impact of a brief home-visiting module, called "Family Spirit Nurture" (FSN), on American Indian (AI) parent feeding practices associated with increased risk for early childhood obesity, with a primary focus on delaying introduction of infants' Sugar Sweetened Beverage (SSB) (including soda, energy drinks, juice with added sugar and other drinks with added sugar) intake while teaching mothers complementary feeding and responsive parenting practices. The investigators will also assess how water insecurity may moderate parents' feeding of SSBs to young children. Finally, the investigators will explore whether maternal knowledge of oral health practices and/or reduction of infants' SSB intake influences early indicators of infant's oral health (i.e., infants' oral microbiome and plaque formation). Our evaluation will employ a randomized controlled design, in which the control condition receives a beneficial home-safety educational model and assistance in safety proofing their homes for small children. Assessments in both groups will occur at baseline (between 6 and 10 weeks postpartum) and 4 months, 6 months, 9 months and 12 months postpartum. Primary Aims: Aim 1: To determine the effectiveness of the brief (6 lessons) FSN home-visiting parent feeding practice module on reducing SSB initiation and frequency among infants between 3 and 12 months of age. Hypothesis 1: Infants whose mothers receive FSN vs. controls will be less likely to introduce SSBs between 3 and 12 months of age. Aim 2: To determine the effectiveness of FSN to promote optimal complementary feeding and responsive parenting practices. Hypothesis 2: Mothers who receive FSN vs. controls will be more likely to practice recommended complementary feeding and responsive parenting practices between 3 and 12 months of age. Aim 3: To determine the impact of water insecurity on SSB consumption among infants between 3 and 6 months of age. Hypothesis 2: Parents who report water insecurity vs. those who do not will be more likely to give infants SSBs between 3 and 6 months of age. Secondary Aims: Secondary Aim 1: To explore if provision of water to families reduces SSB intake among mothers and infants ages 6 to 9 months of age. Secondary Aim 2: To explore if infants in the FSN intervention have better oral health outcomes than control infants up to 12 months postpartum.
The purpose of this trial is to evaluate the anticaries remineralizing potential of a toothpaste containing 500 ppm fluoride plus fTCP technology relative to a commercially available toothpaste via a double-blind cross-over in situ (or intra-oral) clinical model, whereby approved human participants will wear an orthodontic appliance fitted with an enamel specimen for the duration of a leg (28 days). There will be two test legs.
