The purpose of this study was to examine the oral injury experiences of sport players in a bid to raise awareness of the gravity of problems related to oral injuries and the necessity of mouth guards geared toward preventing mental, physical and economic loss triggered by oral injuries. The subjects in this study were 290 sport players. After their oral injury experiences and use of mouth guards were checked, the following findings were given: 28.6 percent had suffered an oral injury. But just 33.8 percent received education about how to cope with an oral injury. 93.4 percent had never used a mouth guard, and only 25.9 percent felt the need for that. And just 28.3 percent had an intention to use it. felt the need for that. And just 28.3 percent had an intention to use it. Concerning the impact of gender, the female players used more mouth guards. The players didn't use mouth guards a lot regardless of oral injury experiences and education about that, and there was no change in the way they looked at mouth guards, either. The findings of the study illustrated that sport players as well as non-players weren't aware of the importance of mouth guards, though sport players were exposed to the danger of an oral injury all the time. Not only players but non-players should learn about the seriousness of an oral injury, and the necessity of oral guards should be stressed to prevent it.

Dentofacial trauma can result in tooth fracture, avulsion, facial bone fracture. The Unites states and Japan mandated the use of mouthguards for contact sports. But, Korean didn't. Mouthguards divided into ready-made type and custom-made type. Mouthguards protect the lips, intraoral soft tissues, teeth and provide the mandible with resilient support to prevent jaw fracture and dislocations. Sports-related accidents have been reported to be one of the most common causes of dentofacial trauma. Sports trauma of involving teeth with incomplete root formation cause long chair time, multiple visit, economic considerations, additional dental services. So, mouthguards can offer considerable protection against sports-related trauma.

Ocular injuries often accompany midfacial trauma Blindness related to indirect optic nerve injury in midfacial fractures is an uncommon and usually permanent complication. Opic nerve blindness is secondary to an indirect optic nerve injury due to the skeletal distortion that occurs in a facial fracture and almost all are caused by frontal, nasoethmoido-frontal or Le Fort III type fractures. When the loss of vision following midfacial fractures is complete and immediate, the prognosis is poor in spite of treatment. Computed tomography revealed compressin of the optic nerve by bony fragments. And so if injury to the optic nerve is suspected, a CT-scan must be performed and massive steroid therapy must be started as soon as possible. Surgery must be performed if there are hematoma or bony fragments injuring the nerve. The following report concerns two patients who suffered immediate and total loss of vision due to a midfacial fracture with no improvement after massive steroid therapy and surgial decompression.

Objectives: The aim of this study was to investigate the influencing factors on oral and maxillofacial trauma prevention education experience of students majoring in physical education. Methods: A self-reported questionnaire was filled out by 268 students majoring in physical education in Busan. All statistical analyses were performed using SPSS 21.0. The questionnaire consisted of general characteristics(4 questions), TMJ symptoms(9 questions), oral habit(8 questions), and mouth guard awareness(5 questions). The questionnaire was carried out by 5 Likert scale. Higher points of Likert scale showed the negative tendency except the mouth guard awareness. The higher points of mouth guard awareness showed the positive tendency to use the mouth guard. Results: Male students had higher scores of 2.75 points in bad oral habit than the female students(p<0.05). Female students higher score of 1.30 points in mouth guard awareness than male students(p<0.05). TMJ symptoms experience in oral and maxillofacial trauma was 3.15 points which was higher than the prevention education experience without maxillofacial trauma(p<0.001). TMJ symptoms and Mouth guard awareness showed 2.71(p<0.01) and 1.20 points(p<0.001) respectively in students with maxillofacial trauma prevention education experience. These score were higher than those without education experience of trauma prevention education experience. The influencing factors on trauma prevention education experience are mouth guard awareness(p<0.001), oral habits(p<0.01), and temporomandibular joint symptom(p<0.01). Conclusions: The necessity of mouth guards should be emphasized to prevent the serious oral trauma. It is very important to establish the rule for mouth guard use in sports activities. Therefore, oral and maxillofacial trauma prevention education program is needed.

Objectives : This study was to investigate the use of mouth-guards and maxillofacial injuries and to examined the relationship among variables in athletes group. Methods : The subjects were 459(86.5%), who were 18 years or older with mean age of 20.7 years. Data was collected using a self administrated questionnaire from May 25 to June 15, 2009. We surveyed maxillofacial injuries(temporo-mandibular disorders contained) and mouth-guards usage and confidence concerning mouth-guards in athletes. The data were analysed with chi-square analysis, fisher's exact test and logistic regression using the SPSS 15.0 windows. Results : Prevalence of body or maxillofacial injuries experiences was 54.5% for athletes and 47.1% for non-athletes groups(p>0.05). The other hand, the incidence temporo-mandibular disorders was 67.0% for athletes and 49.8% for non-athletes groups(p<0.05). The experience of the use of mouth-guards was 83.3% for athletes and 78.8% for non-athletes, there were not significant differences between athletes and non-athletes groups (p>0.05). Risk factors found to be significantly related to the occurrence of maxillofacial injury were: unused mouth-guards(OR=2.83), no rules for use of mouth-guards(OR=2.46). Conclusions : Based on the findings, maxillofacial injuries experience is highly associated with mouth-guards usage, not only athletes also general people should be educated on the use of mouth-guard in order to reduce the incidence of maxillofacial injuries.

Orbital infection or inflammation is a rare but serious complication of an odontogenic infection. Odontogenic infection can spread to the orbit by one or more of several paths. Such extension is potentially dangerous and can lead to loss of vision or worse. 5-cases of orbital infection and inflammation secondary to infection from upper or lower molar teeth, which extended to the subperiosteal or the retrobulbar region of the orbit, are presented in this report. The infections spreaded to the infratemporal and temporal fossa or the ethmoidal labyrinth, and then to the orbit via the inferior orbital fissure or the lamina papyracea. The clinical presentation, differential diagnosis, route of spread, value of serial CT scanning, treatment and possible complications are reviewed.
