The sensory mechanism in human dentin as revealed by evaporation and mechanical removal of dentin.

abstract：:Since edentate subjects have a reduced masticatory function, it can be expected that the morphology of the cancellous bone of their mandibular condyles has changed according to the altered mechanical environment. In the present study, the morphology of cylindrical cancellous bone specimens of the mandibular condyles o...
