6 Clinical Trials for Various Conditions
The purpose of this study is to demonstrate whether decay causing bacteria are reduced when adhesive xylitol disks are used intraorally three times a day for two weeks in adults with dry mouth.
Mutans streptococci (MS) and lactobacillus species (LB) are the two groups of infectious cariogenic (caries-causing) bacteria most strongly associated with dental caries (dental decay). Infants acquire cariogenic bacteria from their mothers early in development via saliva. There have been several studies that have demonstrated a significant reduction in dental caries associated with consumption of the food additive known as xylitol in children and adults. Xylitol is a non-toxic 5 carbon polyol, approved as a food additive by the FDA, that tastes like and behaves like sucrose in humans. Xylitol is used as a sugar substitute to reduce dental caries as it is not fermentable by the caries causing bacteria. In addition, an observed positive beneficial side effect of this sugar substitute is that xylitol has been shown to reduce mother to child bacterial transfer when used by the mother. It is commonly recommended to wipe infants' teeth and gums with a soft cloth to reduce the formation of dental bacterial plaque. Recently wipes have been marketed that contain xylitol to provide a safe sweet sensation for the infant during this cleaning procedure. However, no study has been conducted that assesses the biological effect of applying xylitol directly to the teeth and gums of infants. This study will be conducted to test whether xylitol applied by swab directly to the infant's teeth and gums will effectively reduce bacterial transfer from mother to child. Children age up to two years old whose mothers have high cariogenic bacterial counts will be recruited to use xylitol wipes 3-4 times daily in addition to their normal preventive regimen. This will be a randomized double blinded study where the control group will receive placebo wipes (with no xylitol) and the experimental group will receive the xylitol wipes. The mother-child pair MS and LB bacterial counts and caries score of the children will be measured at baseline, 3 months, 6 months and 1 year. We will contact all patients that were recruited into the study to inquire whether they are willing to return for further follow-up visits at 1, 2, 3, and 4 years post-wipe treatment completion. If successful, this study will support the use of a simple caries preventive measure that could be easily and safely implemented in young children. Ten MS isolates and unique LB colonies will be isolated from each saliva samples to study their genetic diversities and virulence factors. The investigators will also investigate whether specific MS genes relate to ECC prevention effect of daily xylitol-wipe application using genomic sequencing of MS isolated from current study when the active intervention was applied.
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.
This study compared four mouth rinses/chews for their ability to reduce Streptococcus Mutans after usage. The four that were compared were chlorhexidine gluconate (0.12%), sodium fluoride (0.05%), paraffin wax chewing gum (sugar free), and deionized water. The paraffin wax chewing gum replaced the originally planned coconut oil and served as a placebo comparator.
The goal of this clinical trial is to compare the effect of CBD candy versus sugar free candy on reducing the number of bacteria causing tooth decay, in adults The main question is to see whether CBD have any effect on reducing the number of Streptococcus mutans, in the oral cavity the main bacteria causing tooth decay. Participants will be randomly placed in a group, and assigned to take either CBD-infused lozenge (if in the experimental group) or a sugar-free candy (if in the control group) once a day for 15 days. A sample of saliva will be collected and analyzed in a lab before and after consumption of the candy to see whether either product could reduce the harmful bacteria in the mouth.
Young children with asthma who use drugs for their asthma are at higher risk for tooth decay. These drugs can cause (1) dry mouth from less saliva secretion and (2) acid mouth that causes teeth to become soft and bacteria to multiply. Herbal lollipops may reduce the risks of tooth decay in young children. The purpose of this research is to determine how well herbal lollipops can improve the negative effects of asthma drugs over a 6-month period. Herbal lollipops contain Chinese licorice root.
