Pulpal hyperemia is characterized by congestion of blood within the ______ chamber

If a strong light is directed on the labial surface of the injured tooth, the coronal portion of the tooth may appear ______ compared to adjacent teeth

Internal hemorrhage may cause the rupture of capillaries and the escape of ______ cells

In more severe cases of internal hemorrhage, there is pigment formation in the ______ tubules

The change in color due to internal hemorrhage is evident within 2 to 3 weeks after the injury, and although reversible to a degree, the crown of the injured tooth retains some of the ______

The color change from internal hemorrhage may be evident for several weeks after the accident and often indicates a ______ prognosis

In cases of internal hemorrhage with severe discoloration, there is some chance that the ______ will retain its vitality

The likelihood of vitality is apparently low in primary teeth with ______ discoloration

If detected early, the tooth may be retained when ______ procedures are instituted.

The occurrence referred of a perforation as “perforating hyperplasia of the ______”

Due to damage to the periodontal structures and the pulp may not become involved.In case of sever trauma with some displacement of the tooth, Gross areas of the root have been ______.

In exceptional cases the resorption may become arrested, and the tooth may be ______.

A severe blow to a tooth causing displacement often results in ______ necrosis.

The blow may cause a severance of the apical vessels, in which case the pulp undergoes autolysis and ______.

In a less severe type of injury, the hyperemia and slowing of blood flow through the pulpal tissue may cause eventual ______ of the pulp.

A tooth receiving an injury that causes coronal fracture may have a better pulpal prognosis than a tooth that sustains a severe blow without fracturing the ______.

Calcific metamorphosis of the dental Pulp is characterized by partial or complete obliteration of the pulp chamber and canal. Although the radiograph may give the illusion of complete obliteration, an extremely fine root canal and remnants of the pulp will ______

The crowns of teeth that have undergone calcific metamorphosis may have a yellowish, ______ color

Primary teeth demonstrating calcific metamorphosis will usually undergo normal root ______

A permanent tooth showing signs of calcific changes as a result of trauma should be regarded as a potential focus of ______ must be kept under observation or treated endodontically

Internal resorption is a destructive process generally believed to be caused by ______ action

Internal resorption may be observed radiographically in the pulp chamber or canal within a few weeks or months after an ______

If progression of internal resorption is rapid, it may cause a perforation of the crown or root within a few ______

Internal resorption is described as 'pink spot' because when the crown is affected, the vascular tissue of the pulp shines through the remaining thin shell of the ______

Therefore either surgical repositioning or the removal of a permanent tooth that becomes ______ is often necessary

The problem may be noticed several months or years later 1- hypocalcification and ______

The presence of a small, pigmented hypoplastic area has been referred to as ______ tooth

Small hypoplastic defects may be restored by the ______ technique

In cases in which the injury to the developing permanent tooth is severe enough to remove the thin covering of developing enamel or cause destruction of the ameloblasts, the subjacent odontoblasts have been observed to produce a reparative type of ______

The irregular dentin bridges the gap where there is no enamel covering to aid in protecting the pulp from further ______

Tooth with sharp bend in crown or root occurs after the intrusion or displacement of an anterior primary ______

Risk of pulp necrosis (from the lowest) Concussion, subluxation, extrusion, lateral luxation, intrusive luxation – 100% chances of pulp necrosis and external root ______

In histologic sections, repair can be seen that may cause a mechanical lock or fusion between alveolar bone and the ______ surface

The tooth with a necrotic pulp should be ______ or treated with RCT

Ankylosis is a condition caused by injury to the ______ ligament and subsequent inflammation

Clinical evidence of ankylosis is seen as a difference in the incisal plane of the ankylosed tooth and adjacent ______

The radiograph may show an interruption in the periodontal membrane of the ankylosed tooth, and often the dentin may appear to be continuous with alveolar ______

The ankylosed anterior primary tooth should be removed if there is evidence of its causing delayed or ______ eruption of the permanent successor

If ankylosis of a permanent tooth occurs during active eruption, eventually a discrepancy between the position of this tooth and its adjacent ones will be obvious. The uninjured teeth will continue to erupt and may ______, with a loss of arch length
