Dental Plaque clinical trials at University of California Health
3 research studies open to eligible people
Imaging-based Assessment of Oral Biofilm and Gingival Health
open to eligible people ages 18 years and up
The purpose of this research study is to develop a better way of measuring the health of patients' mouth using photographs and imaging software. The investigators will also study the specific effects of individual toothpastes and mouthwashes on oral health. Participants who have volunteered to be in the study will be asked to use a toothpaste or over a period of 7 days to 6 months. The investigators will determine the participants' oral plaque levels, gum health, and saliva (spit) production with clinical exams as well as photographs of the participants' mouths. It is the hope of the study team to find better ways of assessing the health of patients' mouths and to identify whether gum health can be improved by specific toothpastes or mouthwashes.

Livionex Oral Microbiome and Dental Plaque Control in HSCT Recipients
open to all eligible people
Children undergoing chemotherapy, radiation treatment and Hematopoietic Stem Cell Transplantation (HSCT) have significant difficulties achieving good oral hygiene and dental plaque control. HSCT recipients are at a significant risk for bacteremia and sepsis. Livionex® toothpaste was shown to be effective in reducing dental plaques while containing no additives found in other toothpastes that can cause increased gingival irritation. The investigators hypothesize that improved oral hygiene and better plaque control in pediatric patients receiving chemo/radiation treatment or HSCT may result in reduced oral inflammation, decreased amount of oral bacterial pathogens, and reduced risk of oral-pathogen related systemic bacterial infections. The overall goal of this prospective randomized (2:1) pilot study is to determine whether incorporation of the Livionex® toothpaste in the research regimen could reduce dental plaque.
Orthodontic Varnish Microbiology Study
open to eligible people ages 12-27
Orthodontic treatment is common in teenagers, which typically involve the attachment of metal brackets to the teeth. These brackets often impede proper oral hygiene, leading to plaque accumulation and the development of white spots lesions (the early stage of cavity development). Our study aims to investigate the efficacy of different commercially available fluoride varnishes to treat these white spot lesions after the completion of orthodontic treatment and evaluate their effect on the oral microbiome. Target enrollment is 120 subjects. The study will follow a split-mouth design, with each subject receiving different treatment on the left and right sides of their mouth. The subjects will be randomized into 3 groups, with each group receiving two of the following three options: placebo varnish, traditional sodium fluoride varnish, and a resin-modified glass ionomer light-cured fluoride varnish. There will be 4 total visits for this study: Baseline (day 0): Oral health assessed, plaque collected, intraoral photos taken, dental cleaning performed, DiagnoDent measurements taken, varnishes applied T1 (day 30): Oral health assessed, plaque collected, intraoral photos taken, DiagnoDent measurements taken, varnishes reapplied T2 (day 90): Oral health assessed, plaque collected, intraoral photos taken, DiagnoDent measurements taken, varnishes reapplied T3 (day 180): Oral health assessed, plaque collected, intraoral photos taken, DiagnoDent measurements taken, dental cleaning performed Participants will be instructed to use regular fluoridated toothpaste and floss twice per day for the duration of the study.
