130. A patient complaining from a severe edema in the lower jaw that increases in size upon eating, Diagnosis is:
A. Salivary Gland. *** (Submandibular Salivary. Gl.)
Toughness: It is defined as the amount of energy per volume that a material can absorb before rupturing. The ability of a metal to deform plastically and to absorb energy in the process before fracture is termed toughness.
The mandible will always deviate to the side of injury. A patient who sustaind a subcondyler fracture on the left side would be unable to deviete the mandible to the right.

136. An adult had an accident, maxillary central incisors intruded, lip is painful with superficial wound what is the trauma’s classification:
A. Luxation. ***
B. Subluxation. C. Laceration. D. Abrasion. E. Contusion.
Vazirani-Akinosi technique - a closed-mouth injection technique, the syringe is "advanced parallel to the maxillary occlusal plane at the level of the maxillary mucogingival junction.
(Defect factor 9 : Hemophilia B)
If the intruded incisor is contenting the permanent tooth bud, the primary tooth should be extracted.
- The mandibular arch lies between the first branchial groove and the stomodeum ; from it are developed the lower lip, the mandible, the muscles of mastication, and the anterior part of the tongue. - The ventral ends of the second and third arches unite with those of the opposite side, and form a transverse band, from which the body of the hyoid bone and the posterior part of the tongue are developed.
During the third week there appears, immediately behind the ventral ends of the two halves of the mandibular arch, a rounded swelling named the tuberculum impar, which was described by His as undergoing enlargement to form the buccal part of the tongue. More recent researches, however, show that this part of the tongue is mainly, if not entirely, developed from a pair of lateral swellings which rise from the inner surface of the mandibular arch and meet in the middle line.
Intrusive luxations, or intrusions, result from an axial force applied to the incisal edge of the tooth that results in the tooth being driven into the socket.
