Adhesion is the physical interaction between two unlike molecules with one another.In denture it is mainly applicable among the saliva and the denture base material(acrylic resin).The closer the surface of denture and saliva,the adhesion is increased.The adhesion is more if contact angle is less.The wetting of saliva is more on oral mucosa than on denture base.thus adhesion also depends upon the viscosity of saliva.The thin layer binds more effectively than thick but ropy saliva may have some advantage especially resisting flow into space between denture base and mucosa,this is negated if the film formed is thick in first place.
