Cavities clinical trials at University of California Health

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.

Saliva insulin shows promise as a non-invasive biomarker of high carbohydrate intake and/or insulin resistance, key risk factors for metabolic dysregulation and caries. Saliva insulin monitoring could potentially inform the planning and evaluation of interventions to prevent child obesity, diabetes and caries, without relying on self-reported measures from children, parents, child care providers or teachers. School-based public health screening programs, which have staff and data collection infrastructure in place to regularly and systematically collect saliva during oral health screening, have opportunity to monitor saliva insulin. This randomized controlled trial explores if saliva insulin is responsive to the kinds of obesity and caries intervention currently in progress in schools, namely drinking water intervention. Public health programs may justify adding saliva collection to protocol already in place if saliva insulin data are found to be actionable, i.e. sensitive to risk and intervention.
