The purpose of this study is to investigate the properties about oral health of 250 physical education middle-high school students. From April 2013 to June, we researched their oral health knowledge, attitude, behavior and oromaxillofacial trauma using oral examination and structured survey and implemented independent t-test and frequency analysis. Female students were statistically higher in DMFT rate(Female 22.30 % and male 15.41% in average). Middle school students were higher in periodontal health status score compared to high school students(Middle school 1.19 and high school 0.68 in average). Female students scored higher in both oral health knowledge(Female 3.69 and male 2.81 in average) and behavior(female 38.26 and male 36.92 in average). Therefore, the implementation of oral health education and personalized oral health program that considers properties of physical education middle-high school students.

This study was conducted to investigate the oral health related quality of life in elders concerning to residence at urban and rural. The subjects were 215 old persons who were over the 60 years old, living at Sahagu in Busan(113persons) and Geojer Si in Kyungnam (102persons). The data for this study were collected by direct interviewing method from May 30 th to June 30 th and September 12 th, 2005. Cushing & Sheiham's Sociodental Scale which measures oral health related quality of life was used for this study. The data were analysed by a computerized program named statistical package for social science including frequency, percentage, t-test. The results of this study were summarized as follows; 1. Mean score of the oral health related quality of life in elders is $2.42{\pm}1.03$ 2. There was a significant difference in oral health related quality of life in elders between the age 60 ~ 70 years group and the over than 71 years group(P < 0.01). 3. There was a significant difference in oral health related quality of life in elders between the urban and rural group(P < 0.05). Above findings suggest that further study about proper program for geriatric oral health evaluation is necessary in improving the oral health related quality of life in elders.

Condylar hyperplasia is a pathologic condition showing 3-dimensional skeletal hyperplasia of the mandible. The reason for condylar hyperplasia is not yet known, but the effects of hormone, trauma, infection, genetics, fetal condition, and hypervascularity are known as possible reasons. When we diagnose a patient as having condylar hyperplasia, it is important to decide if it is in progress or not. Treatment for facial asymmetry due to condylar hyperplasia are decided accordingly, including condylectomy, that is removal of growth site of the affected condyle, and conventional orthognathic surgery only or condylectomy with orthognathic surgery after the completion of growth. Therefore, it is important to determine the growth state of condylar hyperplasia in treatment stability. This is verified through bone scan and regular check-ups with 3D CT or PA cephalogram. This case report introduces an improved case of facial asymmetry with condylectomy together with orthognathic surgery.

Maxillofacial deformities are not considered to be a trouble in social life but function. So many maxillofacial plastc surgeons has made efforts to overcome these troubles and bring out more positive life. The proper proportion and shape decide esthetic quality. Lower third of face was consist with lip, cheek, mandibular lower border and mandibular angle. Widening lower third of face give a impression with muscular and recklessness. And lower and wide mandibular angle makes face square shape. Unilateral involvement cause asymmestric face. These face is considered unfavorable, especially in Korea or Japan. We prevent a number of with mandibular angle Bulging which was corrected with mandibular osteotomy or masseter myotomy.

In children, change in lifestyles such as an increase in participation of physical activities has increased the chance of receiving an injury, harming the child and their parents. This study was carried out to give basic information of traumatic injuries to the upper anterior teeth which can be used in prevention of future complications that may arise. From June, 2002 to May, 2003, of the 8,799 children in their primary and mixed dentition visiting Department of Pediatric Dentistry, College of Dentistry, Yonsei University 955 upper anterior teeth(primary 543, permanent 412) of 487 children(male 316, female 171) with traumatic injures to the upper incisors were studied. The results were as follows: 1. Trauma to the primary teeth prevailed at the age of 1-3 and to the permanent teeth at the age of 7. The male to female ratio was 1.85:1. 2. Trauma to the upper incisors for both the primary and permanent teeth occurred in the afternoon. Primary teeth were injured most frequently in the home(44.1%) and the permanent teeth outdoors, in the street(17.5%). 3. Both the primary and permanent teeth were most injured by fall-down injuries(39.8%, 12.9%), and next were collisions(22.2%, 6.0%). For the primary teeth, high fall, traffic accident, violence and sports are next in order, and for the permanent teeth, violence, sorts, traffic accidents were next. 4. Average number of 1.6 primary teeth and 2.8 permanent teeth were injured with the right central incisor most prevailing. 5. Crown fracture without pulpal exposure and subluxation injures were highest in frequency in both the primary and permanent teeth.

Penetrating injuries in the head and neck region are not common but can pose difficult situations to manage properly. In small cross-sectional area, the neck housed many vital structures, such as carotid artery, internal jugular vein, cervical spines, esophagus, laryngotracheal complex and nerves. Because each vital structure is located within the fascial compartments, bleeding into these closed spaces can give rise to compression of surrounding structures, which may result in compromised airway. Therefore, management of the penetrating injuries should be based on the fully understanding of anatomical relationships, accurate clinical examinations, a careful history taking and the proper treatment planning. We present two cases of penetrating injuries in the head and neck region and discuss on the clinical considerations for the proper management with the literature review.

The 2nd, 3rd, 4th 6th cranial nerve and the ophthalmic division of the 5th cranial nerve are derived from the optic foramen and superior orbital fissure. When these contents are attacked by a trauma the superior orbital fissure syndrome or the more severe orbital apex syndrome are onsetted. As their treatment we can consider the conservative treatment with the hypertonic solution and steroid. Also we can consider the more radical surgery. But their indications are debatable. As the emergency state the treatment plan requires rapid decision and very much considerations equaly. And the legal problems can be happened.

Botulinum toxin type A (BTX-A) inhibits muscle contraction, which leads to reversible muscle atrophy and paralysis. Therefore, BTX-A injection can be an effective treatment of facial asymmetry that originated from the uncoordinated muscle movement. A 52-year-old patient was referred from another hospital for the correction of post-traumatic sequelae. The patient had prominent scar in the mandibular symphysis area with asymmetric lower lip movement. The reason for this asymmetric lower lip movement was due to damage in the lower lip depressor muscle. After the injection of BTX-A on the lower lip depressors, asymmetric lip movement has been improved.

False aneurysms(Pseudoaneurysms) and arteriovenous fistulas have only rarely been reported in the facial region. In this region the false aneurysm arises most frequently in the superficial temporal and facial artery, but other branches of the external carotid are sometimes involved, including the maxillary and lingual artery. False aneurysms can be occurred by blunt trauma that either laceration or rupture the full thickness of the arterial wall. The diagnosis of a false arterial aneurysm can be often made solely on the basis of physical examination. Angiography is helpful for conformation, for delineating the lesion and its vascular supply, and for ruling out the presence of associated vascular lesions such as arteriovenous fistulas. Ultrasonography may also be useful in delineating lesions that are not easily accessible for physical examination. Treatment of false aneurysms is excision, ligation, and arterial embolization. This is a case of false aneurysm of the lingual artery after facial trauma caused by traffic accident. The lesion was successfully treated by embolization and ligation of the lingual and facial branches of the external carotid artery.

From the standpoint of general guidelines of a dentist, the following conditions should be considered before replanting a permanent tooth. The avulsed tooth should be without advanced periodontal disease. The alveolar socket should be reasonably intact in order to provide a seat for the avulsed tooth. The extra-alveolar period should be considered, i.e. periods exceeding. 2 hours are usually associated with marked root resorption. But, the above mentioned regulations are often difficult to keep in the actual situation of the medical emergency room, owing it to the delay of primary medical care in multiple trauma patients. The successful cases have been reported with minimal root resorption in the long-term periods, in spite of extra-alveolar periods of several hours and combined alveolar bone fracture. This is a case report regarding the effect of endodontic drainage in delayed replantation after a prolonged extra-alveolar period of the avulsed teeth with alveolar bone fracture.
