Bone substitute in the repair of the post-extraction alveolus.

In recent years there has been increasing interest in the choice of the best material for bone substitutes. Experimental models enable estimation of biological potential, efficacy and safety of a biomaterial before its clinical application. The aim of this study was to evaluate the response of a bone substitute, UNC bone matrix powder (MOeP-UNC), for repairing the post-extraction alveolus in Wistar rats.

Effect of low-power radiation (helium/neon) upon submandibulary glands.

Objective: The aim of this work was to study the effect of low-power laser radiation on guinea pig salivary glands.

Background Data: Low-power laser radiation changes some cellular functions. The effect on salivary glands has not been sufficiently studied.
