Periodontium is a connective tissue ¬ Consequently, located in the so-called periodontal ligament, ie, in the space bounded by ¬ bounded on one side of the dental lamina compact cell ¬ ki, on the other - the cement of the tooth root. At all about pulling the hole of the tooth ¬ connective tissue periodontal (periodontal membrane) is in direct contact with the jaw bone, through the apical hole - with the pulp of the tooth, and the edges of the cell -
with the gum and jaw periosteum.

• Infectious periodontitis. The main role in the development of periodontal infection are bacteria, mainly streptococci, nonhemolytic streptococci among which is 62%, zelenyaschy - 26%, hemolytic - 12%. Coccal flora usually sow together with other microorganisms - veylonellami, lactobacilli, yeast fungi.
