We investigate the cryptanalysis of reducedround RC6 without whitening. Up to now, key recovery algorithms against the reduced-round RC6 itself, the reduced-round RC6 without whitening, and even the simplified variants have been infeasible on a modern computer. In this paper, we propose an efficient and feasible key recovery algorithm against reducedround RC6 without whitening. Our algorithm is...

The aim of this study was to determine heritability estimates of treatment responses to a 10% hydrogen peroxide strip-based whitening system in twins. Eighty-five twin pairs were randomly assigned to 10% hydrogen peroxide whitening strips or placebo strips without peroxide. Both twins (monozygotic or dizygotic) received the same treatment. Maxillary teeth were treated for 30 minutes twice daily...

INTRODUCTION Common clinical experience suggests that tooth whitening agents are 100% effective. This study uses meta-analysis of data from published randomized controlled clinical trials to determine the efficacy of tooth whitening agents. METHODS A MEDLINE search strategy was developed and implemented to systematically identify clinical trials on dentist-prescribed, home-applied tooth white...

3,6-Anhydro-l-galactose (AHG), a major monomeric constituent of red macroalgae (Rhodophyta), was recently reported to possess skin whitening activity. Moreover, AHG-containing oligosaccharides, such as agarooligosaccharides (AOSs) and neoagarooligosaccharides (NAOSs), have various physiological activities, including anti-inflammatory, antioxidant, and skin moisturizing effects. In this study, A...

Background and aim: the present study aimed to assess the effect of teeth whitening strips on dental plaque pH in vivo. Materials and Methods: This in vivo experimental study was conducted on 21 individuals, who were requested to use Crest 3D whitening strips for 30 minutes once a day and for 14 days according to the manufacturer’s instructions. Dental plaque pH was measured using GC p...
