PPMANC1 and PMMANC2 nanocomposites have been fabricated using two reactive clays by methods characterized in order to estimate the impact of different dispersion states on mechanical properties. A simple economical process polymerisation is adopted develop PMMANC an Algerian clay, trying optimize distribution PMMA clay layers. Two distinct types organic mined, labelled as (i) benzyltrimethyl am...

objectives: composite repair is a minimally invasive and conservative approach. this study aimed to evaluate the effect of an additional hydrophobic resin layer on the repair shear bond strength of a silorane-based composite repaired with silorane or methacrylate-based composite. materials and methods: sixty bar-shaped composite blocks were fabricated and stored in saline for 72 hours. the surf...

statement of problem: accumulation of plaque and staining due to a rough surface,  and  penetration  of  colourant  agents  from  food  and  beverages  in to the resin composite results in an incomplete polymerization. there is a little information on the effect of finishing and polishing techniques on the discoloration of nanohybrid and microhybrid composites when exposed to staining solutions...
