Dental Evulsion
Tooth ablation (also known as ''tooth evulsion'', ''dental evulsion'' and ''tooth extraction'') is the deliberate removal of a person's healthy teeth, and has been recorded in a variety of ancient and modern societies around the world. This type of dental modification is visually very striking and immediately obvious to other people from the same or different communities. There are numerous reasons for performing tooth ablation, including group identification, ornamentation, and rites of passage such as coming of age, marriage and mourning. The social meaning of tooth evulsion is likely to remain unknown for ancient populations and may have changed over time within those groups. Dental evulsion can significantly affect the emergence, occlusion and wear patterns of the remaining teeth. Procedure There are various techniques used to perform dental evulsion; however, regardless of the technique, dental evulsion could not have been achieved without causing pain and a risk of infecti ...

Dental Avulsion
Dental avulsion is the complete displacement of a tooth from its socket in alveolar bone owing to trauma. Normally, a tooth is connected to the socket by the periodontal ligament. When a tooth is knocked out, the ligament is torn. Avulsed permanent teeth may replanted, i.e., returned to the socket. Deciduous teeth are not replanted due to the risk of damaging the permanent tooth germ. Immediate replantation is considered ideal, but this may not be possible if the patient suffered other serious injuries. If properly preserved, teeth may be replanted up to one hour after avulsion. The success of delayed replantation depends on the survival of the cells remaining on the root surface. Storage in an environment similar to the tooth socket can protect these cells until the operation. Prevention Contact sports carry a significant risk of dental injury, which can be reduced by wearing a mouthguard or helmet. Mouthguards are often less effective if not fitted properly to the wearer.

Canine Tooth
In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, or (in the context of the upper jaw) fangs, eye teeth, vampire teeth, or vampire fangs, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called ''incisiform''. They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two maxillary canines and the two mandibular canines. Details There are generally four canine teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterally to ...
