Gingival Inflammation

induced gingivitis
Brief summary
This is a clinical research study designed to measure changes in inflammation and the oral microbiome during a phase of good oral hygiene and the absence of oral hygiene. The goal of the study is to investigate the interplay between local oral inflammation, microbiota and systemic immune responses.
Detailed description
An experimental gingivitis model will be used to explore changes in inflammation and the oral microbiome during gingivitis induction and resolution phases. Following consenting, screening, and enrollment, a dental intraoral (IO) scan or "digital impression" will be taken of the maxillary arch of each subject for the construction of an individual 3D printed tooth shield stent for use during the trial period. The customized stent (made of FDA approved resin material) will be used only on the experimental quadrant, and only during tooth brushing to prevent oral hygiene. Biological samples (blood, mucosal swabs, plaque biofilm, saliva, and gingival crevicular fluid) will be collected at each visit (pre-30 days, Baseline (Day 0), Day 3, Day 7, Day 14, Day 21, and Day 28. Plaque and gingivitis examinations will be taken at each visit.

Extended use of antibiotics or therapeutic mouthwash (eg: Chlorhexidine) any time during the three months prior to entry into the study; 8. Ongoing use of medications known to affect the gingival tissues (i.e. calcium channel blockers, phenytoin, cyclosporine) 9. Current smokers (or users of tobacco and vaping products) and subjects with a history of alcohol or drug abuse; 10.
