Research results

Several independent clinical studies have proven the effectiveness of the iWhite Instant technology. The first clinical study performed by a dental expert proved that the technology of iWhite Instant gave an immediate teeth whitening effect after only one application. The study also demonstrated that the product was well tolerated and easy to use. Some patients had up to 8 shades improvement after one application. The second study, performed at the German University of Witten/Herdecke, confirmed the teeth whitening efficacy of iWhite Instant and concluded that the product effectively removes stains hereby giving visible teeth whitening effects after only one application. These effects were instant but also remained in time. A most recent study analyzed the remineralization properties on enamel defects of the iWhite Instant technology used in iWhite Instant 2. This study was performed by King’s College London Dental Institute. The results show that iWhite Instant 2 demonstrated strong enamel repair capabilities and contributed to remineralization of damaged enamel.


1. Clinical in-vivo study

Instant results

A randomized double blind clinical study was conducted by independent, well-respected dental expert. This dental professional was the former president of the Belgian Academy of Esthetic Dentistry (BAED) and member of several academies of esthetic investigatory and has been performing whitening procedures for more than 20 years.

Results from this study on the effectiveness of iWhite Instant showed an average of 4.4 shades, while some patients had results of 8 shades after one 20 minute treatment.

This shade guide standard incorporates 16 shades, systematically arranged from light to dark into four color groups, and provides a universal tooth-color terminology. The positioning of the shade guide is: B1, A1, B2, D2, A2, C1, C2, D4, A3, D3, B3, A3.5, B4, C3, A4, C4 eventually the bleaching colors (OM1, OM2 & OM3) are added in front of the initial B1.

2. University study: Witten/Herdecke

This clinical study was performed at the University of Witten/Herdecke, a well-known university with a high standard dental department. The primary objective of this study was to evaluate and compare the teeth whitening effect of iWhite Instant with a placebo group. The color measurements were performed by a calibrated investigator using the Vita Classical Shadeguide (see study above).

Results

The whitening effects of one application with iWhite Instant were instant and remained in time. All subjects showed shade improvements in the tooth color assessments. 85% of the subjects had a maximum shade improvement of 4 shades (figure below). There were no subjects which showed a non-response.

 

None of the participants reported hypersensitivity and the majority of the patients saw visible whitening after using iWhite Instant. These results were assessed 24 hours after the initial 20-minute application. This means that the whitening effect did not disappear after one treatment and are still noticeable after a day.
 


3. University remineralization study: King’s College London

The remineralization study was performed at King’s College London Dental Institute. The goal was to analyze remineralization data of iWhite Instant 2 against several controls. Caries-free enamel discs were cut from extracted human teeth. An air abrasion kit was used to create damage to the enamel. At 4 time points the damaged enamel (AE) was compared to the control enamel (CE).

Results

The enamel was treated with iWhite Instant 2 and with a placebo. After treatment with iWhite Instant 2 the damaged enamel (AE) is comparable to that of the control surface (CE), suggesting damage repair. After treatment with the placebo, the enamel defects are still visible in the enamel.

We can conclude that iWhite Instant 2 demonstrated repair capabilities and contributed to the remineralization of the damaged enamel.
