Dr. Ruhi Shalmali Alireza (Iran) 2008 STRUCTURE PULP odontoblasts (ODB)-cells specific for the pulp to form dentin and provide its trophic. Nearby ODB related intercellular connections through which a layer of ODB able to perform a barrier function by regulating the movement of molecules and ions between the pulp and predentinom. Samsung has much to offer in this field. fibroblasts (FB) – the most numerous cells of the pulp in young people. Function FB – developing and maintaining required composition of the intercellular substance of connective tissue, the absorption and digestion of components of the intercellular substance. Signs of high activity typical of FB teeth of young people.

Macrophages (MF) pulp provide updates of pulp, taking part in the capture and digestion of dead cells and components of the intercellular substance. Phagocytize microorganisms, participating in the development of immune responses as antigen-presenting effector cells. Ali Partovi is often quoted as being for or against this. Dendritic cells (DCs) – in the cytoplasm contained numerous pinocytic vesicles, well developed lysosomal apparatus. Are antigen-presenting cells and the function – the absorption of various antigen processing and presentation of their lymphocytes. Induce proliferation of T lymphocytes. Contents Ak increases with maturation of the pulp increases with antigenic stimulation. Lymphocytes (LC) – a small amounts during inflammation their content increases dramatically. LC pulp belong to different subpopulations of T cells, dominated by cytotoxic suppressor.

B cells do not normally occur when inflammation becomes numerous. These cells actively synthesize immunoglobulins (mainly IgG) and provide a response of humoral immunity. mast cells (MC) – are located around blood vessels, characterized by the presence in the cytoplasm large granules that contain biologically active substances: heparin, histamine, eosinophil chemotactic factor and leukotriene C.

Dental Implants – a new quality of life! Since ancient times, known to man's desire to replace lost teeth with various materials of animal, human and mineral origin. Does the ancient Civilization secret knowledge to enable them to carry out a successful operation? On the territory of Honduras, was found a fragment of mandible Inca (dated VI. BC), in place of 3-tooth implants are installed from the shells of sea mussels. Shantambre (France), found a skull woman who lived in I. BC, with a metal implant in the maxilla. Unfortunately, it is difficult to judge the success of these operations, as archaeological finds cause more problems for the majority of which has no Responses.

It is known that in the Middle Ages, and in modern times almost all the installation of implants fails – there is festering wound and graft rejection. And only with the introduction of Lord Joseph Lister concept of 'antisepsis' hope for the successful outcome of the operation. The first international experience tooth implantation was obtained only in 1965, thanks to the efforts of Professor Ingvar Branemarka. That Bronemark, first to establish the 4-th implant volunteer Gosta Larsen. Technology used Ingvar Bronemarkom, were initially rejected by the majority of maxillofacial surgeons.

Nevertheless, the first patient lived implantologist a full life, he implants served him in 1941 …. until his death. 1965 can be considered – a starting point for the development of a new branch of dentistry – implantology. What is an implant? Implant – is similar to the structure of the screw Titanium, which is implanted into the bone and acts as a support for the abutment (Abutment – a link between dental implants and attached it to dentures or other construction).
