The phenomena of adhesion and cohesion are reviewed and discussed with particular reference to dentistry. This review considers the forces involved in cohesion and adhesion together with the mechanisms of adhesion and the underlying molecular processes involved in bonding of dissimilar materials. The forces involved in surface tension, surface wetting, chemical adhesion, dispersive adhesion, di...

Adhesion of the tendon is a major challenge for the orthopedic surgeon during tendon repair. Manipulation of biological environment is one of the concepts to prevent adhesion. Lots of biochemicals have been studied for this purpose. We aimed to determine the effect of phospholipids on adhesion and biomechanical properties of tendon in an animal tendon repair model. Seventy-two Wistar rats were ...

Cell-cell adhesion is an inherently nonlocal phenomenon. Numerous partial differential equation models with term have been recently presented to describe this phenomenon, yet the mathematical properties of model are not well understood. Here we consider a two kinds cell-cell adhesion, satisfying no-flux conditions in multidimensional bounded domain. We show global-in-time well-posedness solutio...
