14 Day Lumineux Gingival Study
To determine the effect over 14 days of Lumineux OE Whitening Strips on gingival and mucosal tissues, dental hard tissues, and tooth color.
Thirty subjects used the Lumineux OE Whitening Strips daily over a period of 14 days, in accordance with the product use directions. Thus, 1 strip was allocated to be used on the upper anterior teeth, and the other on the lower anterior teeth each day. On Days 0, 7 and 14, the oral soft and hard tissues were examined carefully by a dentist, and tooth color was measured on the 12 anterior teeth using a digital colorimeter under standard, calibrated lighting conditions. Each participant completed a questionnaire daily to document perceived effects on the oral hard and soft tissues. No whitening-related adverse effects or symptoms were reported by subjects or observed by the dentist during 14 days of whitening strip use. On average, teeth became 5.5 digital Colormaster V shades lighter after using the whitening strips for 7 days, and 13.3 digital Colormaster V shades lighter after 14 days. Mean improvement in tooth color was statistically significant for Day 7 vs. Day 0, Day 14 vs. Day 7, and Day 14 vs. Day 0 (P < 0.01).
