[Mastocytes and the oral cavity. Anatomy and function].
One hundred and three teeth with chronic pulpitis, twelve chronic periapical lesions and eleven oral various soft tissue biopsies were used to discuss the presence, the anatomy and function of mast cells. The mast cell induces veinules dilatation during the early phase of inflammation by histamine release, collagen lysis, bone resorption and epithelium proliferation. It can be observed in every chronic lesion and plays a part in both humoral and cellular immunological phenomenons. A more accurate knowledge of its biochemical actions could help in understanding the mechanism of pain in certain clinical dental crisis.
