objective: different methods have been suggested to overcome the polymerization shrinkage of composite restorations. changing the light curing protocol to improve polymerization by using new light curing units is among these methods. the new devices are more efficient, portable and durable and produce less heat. this study aimed to assess the marginal microleakage of class v composite restorati...

This work describes the obtention of chitin and chitosan from brown shrimp exoskeleton (Farfentepenaeus californiensis), which is collected Gulf California. The isolation process was carried out by a consecutive treatment that includes demineralization deproteinization. On other hand, preparation conducted through alkaline hydrolysis, product purified using membrane filters series to homogenize...

The aim of this study was to produce synbiotic yogurt using different inulin levels (0, 1 and 2%) and probiotic bacteria. Inulin in two forms commercial and extracted from artichoke root was prepared, and chemical and sensory evaluation were performed. The results of inulin analysis showed that pH, dry matter, degree of polymerization, purity, appearance and taste for the inulin extracted f...
