Tooth avulsion is the complete displacement of the tooth outside the socket. Of all the dental injuries it is by far the most serious because not only it severes the pulpal blood supply but it also exposes the cells of the PDL to the external environment. Thus it is a complex injury that affects the pulp tissue, periodontal ligament and alveolar bone3,, possibly also affecting the apical bundle. The periodontal ligament surrounding the erupting teeth is loosely structured and the alveolus is elastic at these ages. These factors offer only a minimal resistance to an extrusive force.

Tooth avulsion is the complete displacement of the tooth outside the socket. Of all the dental injuries it is by far the most serious because not only it severes the pulpal blood supply but it also exposes the cells of the PDL to the external environment. Thus it is a complex injury that affects the pulp tissue, periodontal ligament and alveolar bone3,, possibly also affecting the apical bundle. The periodontal ligament surrounding the erupting teeth is loosely structured and the alveolus is elastic at these ages. These factors offer only a minimal resistance to an extrusive force. Interruption of the blood supply leads to pulp necrosis, since revascularization of the pulp throughout its extent is possible, yet not very probable. When it occurs, it has serious consequences. The adverse psychological impact of a lost tooth on a child and the fear of being mocked at by peers is one of the first. The resulting empty site is not aesthetically pleasing and is difficult to fill and replace. Long-term sequelae include shifting of remaining teeth with resulting misalignment and periodontal disease. This book emphazise on tooth avulsion.
