Tooth Decay clinical trials at University of California Health
1 research study open to eligible people
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.
