Design outcomes

Primary

MeasureTime frame
1. Plaque levels assessed using Rustogi Modified Plaque Index at baseline and 6 weeks 2. Gingivitis level assessed visually using Modified Gingival Index (MGI) at baseline and 6 weeks

Secondary

MeasureTime frame
1. Brushing duration assessed using the app at baseline visit, 3 weeks and 6 weeks 2. Surface coverage assessed using the app at baseline visit, 3 weeks and 6 weeks 3. Brushing frequency assessed using the app at 3 weeks and 6 weeks 4. Perceived value at the individual level through collection of patient-reported experience measures (PREMS) using a previously validated 15-point oral health and brushing questionnaire at baseline, 3 weeks and 6 weeks 5. Diagnostic utility of the 3D intraoral scans for the measurement of plaque and gingivitis levels intraorally assessed using a TRIOS intraoral scanner at baseline and 6 weeks
