Tooth fragment lodged in the lower lip after traumatic dental: a case report

In permanent teeth, the crown fracture is often associated with lesions in the surrounding oral tissues particularly at cold which can lead to serious complications.In the presence of a lip edematous, open and / or shredded associated with a coronal fracture, thorough clinical and radiographic examination of soft tissue must be systematic.In fact, lesions of the lip can cover up any foreign bodies or fragments of dental crowns embedded in the wounds.The orbicularis muscle pain on palpation mask their presence making the impalpable and only an X-ray may highlight them.Through this article based on a clinical case, we will describe the process for the diagnosis of including dental fragment at labialis after a dentoalveolar trauma, and the terms of the management.


Introduction
Coronary fractures of upper central incisors are often associated with damage to the surrounding tissue including oral labial level [1].
Typically, crown fractures are easily diagnosed, however, when an open wound is lip associated, special attention should be given as to the future of the fractured fragments.Indeed, lesions of the lip can hide any foreign bodies or fragments dental crowns burried in the wound [2,3].
The extent and severity of traumatic injuries of the lip vary from small lacerations to the loss of large pieces of tissue, thus they present a major challenge in terms of reconstruction options and the decision result surgical management.

Discussion
Open lip sores associated with coronal fractures of the anterior teeth are quite common and can be sources ofvarieties of chronic problems [4,5,6].
The appropriate radiographic evaluation of patients with unfound fractured tooth fragments after maxillofacial trauma is extremely important, since these dental structures may become foreign bodies at risk for ingestion, aspiration or inclusion in the surrounding tissues.
The worst complication is aspiration of foreign bodies that can cause the patient to a variety of chr respiratory problems and even death if not diagnosed early [7,8,9].
In our patient, the presence of enamel-dentin fracture at the upper central incisors, associated with edematous lower lip with an open wound motivated the realization of an X-ray performed at the level of the lower lip which confirmed the presence of these foreign bodies in injured tissues [  The appropriate radiographic evaluation of patients with unfound fractured tooth fragments after maxillofacial s extremely important, since these dental structures may become foreign bodies at risk for ingestion, aspiration or inclusion in the surrounding The worst complication is aspiration of foreign bodies that can cause the patient to a variety of chronic respiratory problems and even death if not diagnosed dentin fracture at the upper central incisors, associated with edematous lower lip with an open wound motivated the realization formed at the level of the lower lip which confirmed the presence of these foreign bodies in The aim of treatment is to prevent wound infection, restore the skin continuity and achieve a good cosmetic result while causing the leas child.In the presence of bruised and soiled by the presence of foreign body wounds, infection is a major risk of infection increases with the support period.Washing with saline is a key time.Antisepsis the injured area appealed preferably povidone iodine or sodium hypochlorite, possibly with chlorhexidine.
The surgery was performed under local anesthesia.The use of vasoconstrictor has reduced bleeding and increased the local effect.The injection was carried out at the wound edges of the skin side where the pain receptors are many and never through the wound to prevent the spread of germs.The tissues of the lower lip were raised and dismissed.Teeth fragments were carefully located and individually deleted [ Fig 5,6].
Effective detection of the presence of residual fractured fragments can be made difficult by a series of factors such as laceration, bleeding, edema and fragmentation December, 2015/ Vol 2/ Issue 4 ISSN 2349-5499

To confirm the removal of fragments in our patient, radiographs soft tissues were immediately carried out, whereupon the remaining two fragments were revealed and previews.Traumatic injuries of the lips present major challenges in terms of reconstruction options andresults of surgical treatment [16,17,18].
The lip is important both aesthetically and functionally.Its surgical reconstruction must ensure the restoration of all its anatomical components ie skin layers, muscle and mucous membranes.In our patient, and for aesthetic reasons, the banks of the lip wound were reconciled without tension, then sutured competed well to have a healing by first intention, that will be an evolution without complications in épidémisation 7 days, on average effective consolidation of 4 weeks and a final ripening of 12 to 18 months [19,20].Some locations are not conducive to sutures by a simple approximation of the banks due to the defect, but at the labial level, the most common pitfall is "false defect" where the banks are immediately discarded by the of sphincters orbicular muscle of the lips cut by the wound.By bringing the banks with dissecting forceps, one often sees that nothing is missing.
Postoperative recommendations are key to the final result.We must protect wounds by creating a moist environment with the application of an antibiotic ointment (egFucidine®), instructing parents to regularly clean the wound to prevent crusting, which extends the time of epithelialization and give a less satisfactory cosmetic result.
In the presence of open skin wound, the tetanus vaccination should always be checked and updated,otherwise making a recall or serovaccination.Indeed, tetanus is a dreaded infectious disease that says when the tetanus bacillus managed to invade the body through a wound as small as it is.

Conclusion
Even if an adequate clinical examination of dentofacial injury is often hindered by soft-tissue edema and bleeding, and is frequently performed under less-thanoptimal circumstances, a soft-tissue laceration associated with a dental injury should always alert the physician to the presence of dental fragment inclusion to the peripheral tissues.In this respect, a plain softtissue radiograph frequently helps to rule out this possibility as presented in this case report.Besides, further diagnostic surveys should be performed if the plain radiographs fail to identify the inclusion, ingestion, or aspiration of these fragments.Also, this paper emphasizes thesignificant role of the dental surgeon consultation before the soft-tissue repair in all orofacial injuries.
The general examination didn't reveal any particular general pathology nor known drug allergy.The extraoral examination noted the presence of a lip open wound, deep enough, extending part of the skin to the mucous membrane portion [Fig 1].Its edges were irregular, bruised and dirty appearance.In addition, other oral mucosa showed no apparent traumatic injury and the occlusion was correct.The dental examination showed enamel-dentin fracture without pulp involvement in the coronary third of the maxillary central incisors [Fig 2].Pediatric Review: International Journal of Pediatric Research
