question:
Question: Do a Profilometric Study to Assess the Role of Toothbrush and Toothpaste in Abrasion Process?
Answer: Besides supporting the fact that toothpaste is needed to create a significant abrasion, this study also showed that a softer toothbrush can cause more abrasion than harder ones. The flexibility of bristles is only secondary to abrasion process and abrasivity of dentifrice has an important role in abrasion process.
answer:
yes


question:
Question: Does macular pigment optical density measurements by one-wavelength reflection photometry -- influence of cataract surgery on the measurement result?
Answer: As established by comparison of pre- to post-operative measurements, cataract presented a strong effect on MPOD measured by one-wavelength reflection method. Particular care should therefore be taken when evaluating MPOD using this method in elderly patients with progressed stage of cataract. Future optimization of correcting parameters of scattered light and consideration of cataract influence may allow more precise evaluation of MPOD.
answer:

yes
