Adhesión a dentina parte I: características del sustrato y sistemas adhesivos
Dentin bonding part I: substrate characteristics and bonding systems

La Odontología Restauradora contemporánea no puede concebirse sin la adhesión de los materiales restauradores a las estructuras dentarias. En mu-chos procedimientos restauradores, no sólo el esmal-te sino también la dentina se encuentra involucrada, por lo tanto, la adhesión a esta última juega un...

Synthesis and MALDI-ToF characterization of dendronized poly(ethylene glycol)s

Braz. j. pharm. sci; 49 (spe), 2013
Well-defined hybrids of linear poly(ethylene glycol)s (PEGs) and dendritic polyesters were prepared via the dendronization of the alcohol end groups of the mono and difunctional linear PEGs. Though useful for rudimentary product characterization, GPC and NMR could not verify the overall structural purity...

Physicochemical and dissolution profile characterization of pellets containing different binders obtained by the extrusion-spheronization process

Braz. j. pharm. sci; 48 (3), 2012
With the purpose of evaluating the behavior of different polymers employed as binders in small-diameter pellets for oral administration, we prepared formulations containing paracetamol and one of the following polymers: PVP, PEG 1500, hydroxypropylmethylcellulose and methylcellulose, and we evaluated the...
