Consider the risk of aspiration following repair in the following specific subgroups of patients: •Intoxicated
•Altered mental status
•Decreased functional capacityIn multisystem trauma patients, always address the more critical issues and injuries first.
Tooth extraction may be a viable option in some cases of primary tooth injuries.
Most essential equipment is available in a prepacked dental tray or dental box.

0.File down sharp edges, if necessary, with a dental drill or emery board.
1.Dental follow-up, as desired by the patient, is for cosmetic purposes only.Ellis class II
1.Cover the exposed surface with a calcium hydroxide composition (eg, Dycal), a glass ionomer, or a strip of adhesive barrier (eg, Stomahesive). 2-octyl cyanoacrylate (Dermabond) has been shown to be an acceptable alternative in the setting of a dental fracture if no other materials are available.[3] The 2-octyl cyanoacrylate decreases tooth sensitivity and provides a protective barrier until dental follow-up.[4]
2.Provide pain medications.
3.Instruct the patient to avoid hot and cold food or drink.
4.Arrange for a follow-up appointment with a dentist within 24 hours.
5.Consider antibiotic coverage with penicillin or clindamycin.Ellis class III
1.Cover the exposed surface with a calcium hydroxide composition (eg, Dycal) or a glass ionomer.
2.Provide immediate dental follow-up and analgesics as needed.
3.Initiate antibiotics with coverage of intraoral flora (eg, penicillin, clindamycin).Dental avulsion
1.An avulsed tooth may be gently cleansed in either normal saline or sterile auxiliary solution (eg, Hank’s balanced salt solution).
2.Avoid scrubbing the tooth or any unnecessary delay before reimplantation.
3.The tooth can be returned to its original position by applying firm finger pressure.
4.Handle the tooth by the crown, and avoid trauma to the tooth root.
5.Stabilize the tooth with a temporary periodontal splint.
6.Provide early dental follow-up.
7.Initiate antibiotics with coverage of intraoral flora (eg, penicillin, clindamycin).Dental subluxation
1.This type of injury may not require emergency treatment.
2.Very loose teeth should be pressed back into their sockets.
3.They should then be stabilized with wire or a temporary periodontal splint (eg, Coe-Pak).
4.Patients with dental subluxation should maintain a soft or liquid diet to prevent further tooth motion.
5.Provide early dental follow-up.
6.Initiate antibiotics with coverage of intraoral flora (eg, penicillin, clindamycin).Dental intrusion
1.These injuries can be left alone and allowed to re-erupt.
2.Provide early dental follow-up.
3.Initiate antibiotics with coverage of intraoral flora (eg, penicillin, clindamycin14/10/2011 at 3:05 pm #14653Drsumitra

CBCT has greatly helped with the question of the elusive microfracture’s presence as well as its extent, both of which are significant factors related to treatment planning. The case below illustrates this challenging question related to a patient that presents with the classic “cracked tooth syndrome
The patient had intermittent hyperemic sensitivity as well as pain upon release from occlusion. With a 3-D evaluation made possible by CBCT, the clinician can better evaluate the presence and extent of microfractures. In this case, close evaluation of axial slices enabled the clinician to verify that a microfracture was present). Additional slices suggested that the microfracture was limited to the coronal tooth structure, as there were no signs of osseous changes in the periradicular attachment. After treatment was initiated, the extent of the microfracture was further verified under the microscopeThe successful outcome to eliminate the patient’s symptoms and to retain the tooth with full coverage was confirmed at the one-year follow-up appointment (VERTICAL ROOT FRACTURES
The following 2 cases illustrate the ability of CBCT to help close the gap in determining the presence of vertical root fractures (VRF).Vertical Root Fractures: Case 1
When the patient presented for evaluation of generalized discomfort in the lower right, a 2-D image was taken (Clinical findings were suggestive of a VRF. However, it was because of the benefit of CBCT that the patient and clinician felt more at ease in proceeding with the extraction of this tooth. CBCT was able to verify and illustrate for the patient the classic 3-D presentation of the changes in surrounding tissue in association with a VRF (Upon removal of this hopeless tooth, granulomatous tissue could be seen along the mesiobuccal root (Figure 4d). The VRF was confirmed when the root was scaled for direct assessment
Vertical Root Fractures: Case 2
The second VRF case illustrates the ease of CBCT to show a straight buccal VRF. This is an obvious limitation of 2-D radiographs. A digital periapical radiograph was taken when the patient presented with a minor localized swelling near the buccal of tooth No. 28 ( Clinically, the probing and presentation of the periodontal tissues suggested that a VRF was present. However, the patient desired more definitive information before extracting the tooth and losing the long spanning bridge. Initial disassembly was undertaken to both eliminate the post’s impact on scatter in CBCT and for initial microscopic evaluation. Upon the post removal, the internal extent of a straight buccal VRF was documented through the microscope (. With the use of CBCT, the classic vertical bone loose adjacent to the straight buccal VRF was accurately demonstrated in this frontal slice (. This additional verification appeased the patient’s desire to be more certain that the tooth’s condition was currently untreatable -
