Forces acting on periodontium Introduction : During the development, the tooth is enclosed in the bony crypt and protected from the external environment. As it erupts, it is subjected to various external forces such as pressure from lips, tongue, cheeks, fingers, the pacifier, and exposure to food. These external forces positions the tooth in neutral position of the oral cavity ( 2 ) . To tolerate the forces, an in built shock absorber is created by nature for each individual tooth called periodontal
The Periodontium The periodontium is a very important structure as it provides the teeth with the support needed for them to function. The structures of the different components of the periodontium, which are: the gingiva, periodontal ligament, cementum, and the alveolar bone, are related to each other and any damage to any component may affect the other components as well. Gingiva: The gingiva, normally covers the alveolar bone with the underlying root and extends just above the cementoenamel
Development of human tooth Dental development can be considered to have two components: (1) the formation of crowns and roots and (2) the eruption of the teeth. Tooth development or odontogenesis is a collection of complex processes by which teeth form from embryonic cells, grow and erupt into the oral cavity. Between the sixth and eighth week in utero, the primary teeth start to develop whereas the permanent teeth begin to form in the twentieth week. If by this time some teeth do not develop, they
