Dental intrusion is an apical displacement of the tooth into the alveolar bone. This injury is accompanied by extensive damage to periodontal ligament , cementum , disruption of the neurovascular supply to the pulp, and communication or fracture of the alveolar socket.
Adult front teeth (which usually erupt at around six years of age) can be replaced immediately if clean. If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt). Reassure the patient and keep them calm.
If apex of tooth is displaced towards the palate and making contact with the tooth germ then tooth is extracted Intrusive Luxation: Displacement of tooth into the alveolar bone (pushed into the socket) causing fracture of the alveolar bone. It is the most damaging injury to the tooth and supporting tissues as ankylosis and pulp necrosis can occur.
A certain intrusive force acting on the incisors is counter-acted by an opposite and equal extrusive force acting at the posterior teeth of the same arch. The extrusive force is felt at buccal of the center of resistance of a molar tooth because the bracket slot in the molar tube or band lies buccal to the tooth.
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
Researchers also found that the dental hygiene habit is associated with a 44 per cent lower risk of blood clots travelling from the heart and about 12 per cent lower risk of irregular heartbeats.
Enamel infractions are diagnosed through a dental examination. A dentist can assess the teeth's condition once the first tooth erupts in the mouth and will continue to do so throughout every appointment. In order for the provider to take preventive action depending on the health of the teeth or any abnormalities, it is important that a child ...
