AIM To compare and evaluate the remineralizing potential of four commercially available products namely SHY-NM, GC Tooth Mousse Plus, ReminPro and Colgate strong teeth on demineralized human teeth. MATERIALS AND METHODS The study included 50 extracted premolars having 3 × 3 mm window prepared on the middle third of the tooth, which was then subjected to demineralization for 48 hours at 37°C. ...
OBJECTIVE To evaluate dietary quality in a sample of pregnant women based on one simple and objective parameter. METHODS Pregnant women (n = 712), between 16 and 36 weeks, attending primary care clinics in Porto Alegre and Bento Gonçalves, Southern Brazil, in 2010 were recruited to take part. The Healthy Eating Index for Brazilian Pregnancy (HEIP-B) was created, derived from the American inst...
BACKGROUND Bleached dental enamel can be more susceptible to staining than the enamel that has never been bleached, especially right after tooth bleaching. The aim of this study is to evaluate the effect of surface treatments and waiting time prior to contact with dye on bleached enamel staining susceptibility. MATERIAL AND METHODS One hundred teeth were bleached with 35% hydrogen peroxide (W...
In 1993 we reported ‘‘exact’’ quantum Monte Carlo ~QMC! calculations of potential energies for the interaction of two helium atoms. For the equilibrium internuclear distance of 5.6 bohr, the calculated interaction energy was 211.01 K with an uncertainty of 60.10 K ~1s!. By 2001 competing methods had achieved similar accuracies in the interaction energies and we repeated our calculations with fa...
This work concerns the measurements of a Bulk Acoustic Waves (BAW) emission filter S parameters and compare with prototypes simulated types. Thanks to HP-ADS, a co-simulation of filters’ characteristics in a digital radio-communication chain is performed. Four cases of modulation schemes are studied in order to illustrate the impact of the spectral occupation of the modulated signal. Results of...
