Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Intensity and extent of extrinsic dental stain on the facial and lingual surfaces of the anterior teeth is measured using Composite Modified Lobene Stain Index at Week 4 and Week 12 2. Intensity and extent of extrinsic dental stain in four different regions (gingival, body, mesial and distal) on the facial surfaces of the anterior teeth is measured using Interproximal Modified Lobene Index at Weeks 4 and 12 | — |
