Oral lacerations during motocross: A case report

Abstract

Motocross is a high-risk sport that can cause serious injuries including oral injuries. However, mouthguard use is not mandatory in motocross. This report describes a case of an oral laceration with exposure of bilateral inferior alveolar nerves as a result of a motocross accident in which the patient was not wearing a mouthguard.

Influence of custom‐made and stock mouthguard thickness on biomechanical response to a simulated impact

“…However, this group is hypothetical and it is not possible to assume that such a maxillomandibular relationship remains stable during sports performance involving sudden movements and adequate pulmonary ventilation. 21 However, as the literature reports cases of facial bone fractures during sports accidents with 17 and without the use of MGs, 22 maximum principal stress results (tensile zones) were required for the bones (Figure 7), and disregarding the results concentrated in the teeth. It is possible to notice that F I G U R E 6 Bar graph and linear behavior from moment 0 until final load with 500 N. Stress peaks generated in the dental elements all the models presented zones of greater fragility in regions that involve the three types of Le Fort fracture-that is, maxillary alveolar process, nasal bone, zygomatic-frontal suture, maxillofrontal suture, nasofrontal suture, orbital surface, ethmoid, and sphenoid.…”

Simulation of mouthguard use in preventing dental injuries caused by different impacts in sports activities

“…However, its use is essential and its benefits are not only restricted to directly preventing damage to the teeth. Thus, it is correct to assume that fracture cases [17] 3.6 0.30 Human bone tissue [18] 13.7 0.3 Human teeth [19] 2.07 × 10 4 0.3 could present worse prognosis if the athlete was not using a mouthguard [3,8,[21][22][23]. It is hoped that doubts by athletes about the benefits of using a mouthguard diminish with this information, since this is one of the main reasons reported for this apparatus not being used during sports practice [20,24].…”

Important aspects during advanced lingual laceration management: report of 2 cases

“…The lacerations including lips, forehead, nose, eyes and tongue are the most common, and two-thirds of all these traumas are represented by lip lacerations, followed by tongue lacerations [1]. The etiology of tongue laceration commonly includes motor vehicle accidents [2], human or animal bites [1,3], or some form of direct trauma to the face.…”

“…Tongue lacerations can make it difficult for emergency physicians to take some decisions, due to difficulty with controlling hemorrhage, shock and direct threat to the airway [2,4,5]. Hemorrhage and disfigurement are the two most common concerns in relation to these injuries, although loss of function, infection, deficient speech articulation and swelling, which compromises the airway, are also mentioned as being sequelae 2,6.…”

“…At present, optimal treatment of tongue lacerations is still conflicting due to contradictory recommendations and lack of up-dated guidelines. The recommendations include suturing injuries located on the dorsum and lateral border; and those that are longer than 2cm in extent, or when hemostasis is not achieved [2]. Some authors have also indicated suturing ''through and through'' injuries of the edge of the tongue [8,9].…”
