Lec. 1  Periodontology: The scientific study of the periodontium in health and disease.  Periodontium: The periodontium describes the tissue that supports and surrounds the tooth. It includes the gingiva, alveolar bone, cementum, and periodontal ligament. The gingiva surrounds the teeth and protects both the bone and periodontal ligament.  Periodontium: The periodontium is a connective tissue consisting of four components: cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue  connective tissue ◼ Group of tissues in the body that maintain the form of the body and its organs and provide cohesion and internal support. Periodontium comprises the following tissues: 1- The gingiva. 2- The periodontal ligament. 3- The root cementum. 4- The alveolar bone. The gingiva: The gingiva is defined as the part of the oral mucosa that covers the alveolar processes of the jaws and surrounds the necks of the teeth. Triangular papilla The gingiva is divided into 2 parts: The free gingiva (FG). The attached gingiva (AG). ◼ Interdental papillae(I.D.P): Is that portion of gingiva that fills the interproximal space between adjacent teeth.0 In anterior regions of dentition the I.D.P. is of pyramidal while in the molar regions they are flattened. In premolar and molar regions the teeth have contact surfaces rather than contact points so the I.D.P.  yo u a nk Th
