The purpose of this study was to analyze the prevalence of Oral and maxillofacial injuries of elementary school children in Suwon, Korea. The sample consisted of 850 boys and girls in a elementary school children in the city. This study conducted a survey by sending questionnaires to school-aged boys and girls, to study a condition of traumatic injuries of teeth. 1. The students who had a traumatic injuries in a oral & maxillofacial area are 125 persons(14.7%); boys 93 persons(21%), girls 32 persons (7.9%). 2. Incidence of traumatic injuries was 1 time 102 persons(81.6%), 2 times 14 persons(11.2%), others 9 persons(7.2%). 3. The causes of traumatic injuries were fall down 65.6%, blow 10.4%, sports 9.6%, traffic accidents 7.2%, tripping 3.2%, others 4%. 4. The distributions of sports related traumatic injuries were roller blade 7 persons, bicycle 2 persons, football 1 person, baseball 1 person, basketball 1 person. 5. Types of traumatic injuries were soft tissue injury(40.8%), tooth fracture(36.8%), extrusion(8.0%), jaw fracture(3.2%), others(11.2%).

Lesch-Nyhan syndrome is a rare X-linked recessive disorder characterized by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyl transferase, which is important in the metabolism of purines. Prevalence of Lesch-Nyhan syndrome is 1:100,000 to 1:380,000 live births, and Lesch-Nyhan syndrome mainly affects males. It is characterized by neurologic dysfunction, uric acid overproduction, and cognitive and behavioral disturbances. The self-mutilation is the most distinctive symptom in Lesch-Nyhan syndrome, appearing about 1 year of age. It is expressed as persistent bites in the oral mucosa, tongue, lips, and fingers, which leads to the total or partial destruction of the affected tissues. Several medical and dental management methods might be performed in Lesch-Nyhan syndrome patients. Dental approaches to prevent injuries caused by self-mutilation include treatments with oral appliances such as mouth guards or lip bumpers, extraction, and orthognathic surgery. This report described two brothers with Lesch-Nyhan syndrome, who injured themselves on oral tissues. The methods of tooth reduction and extraction were performed to prevent injuries caused by self-mutilation.

When a tooth shows discoloration and does not respond to the cold test or electric pulp test (EPT) after a traumatic injury, its diagnosis can be even more difficult due to the lack of proper diagnostic methods to evaluate its vitality. In these case reports, we hope to demonstrate that ultrasound Doppler might be successfully used to evaluate the vitality of the tooth after trauma, and help reduce unnecessary endodontic treatments. In all three of the present cases, the teeth were discolored after traumatic injuries and showed negative responses to the cold test and EPT. However, they showed distinctive vital reactions in the ultrasound Doppler test during the whole observation period. In the first case, the tooth color returned to normal, and the tooth showed a positive response to the cold test and EPT at 10 wk after the injury. In the second case, the tooth color had returned to its normal shade at 10 wk after the traumatic injury but remained insensitive to the cold test and EPT. In the third case, the discoloration was successfully treated with vital tooth bleaching.

When the tooth avulsion occur in accidents the drying damage to the periodontal ligament has extremely detrimental effects on healing. Pulp necrosis always occurs after an avulsion injury, but revascularization can only take place in teeth with immature apexes. Therefore complications after avulsion injuries are common, and treatment must be carried out in a timely and correct fashion to prevent or limit these complications. Every effort should be made to replant the tooth within the first 15 to 20 minutes. If doubt exists that the tooth can be replanted adequately, the tooth should quickly be stored in an appropriate medium until the patient can get to the dental office for replantation. A complication of inflammatory root resorption is occurred by bacterial infection of periodontal ligament and dental pulp. Therefore aseptic endodontic treatment must be carried out in a timely and systemic antibiotics given at the time of replantation and before endodontic treatment are effective in preventing bacterial invasion. Further studies are needed to establish the clinical importance of preparation of the socket and root.

The purpose of this study was to investigate the characteristics of intrusion in primary dentition and to evaluate factors influencing complications of primary and permanent dentition during long-term follow-up period. 61 patients (84 teeth) were selected in this study. Medical records of 61 patients were reviewed and age, gender, cause of injury, site of injury, severity of traumatic injury, other injuries associated with trauma, treatment method, and complications of primary and permanent dentition were examined. Collected data were statistically evaluated using Chi-square test and Fisher's exact test. Intrusion in primary anterior teeth was predominant in boys over girls and fall was the most common cause of trauma. It was most common at home and occurred most in the primary maxillary central incisors. Severity had an effect on the incidence of sequelae in permanent successors (p = 0.014). The incidence of complications was significantly lower in patients with soft tissue injuries than in patients with other periodontal injuries (p = 0.000).

Intubation may lead to several dental complications. Furthermore, a tooth damaged during intubation may be subsequently dislocated. In the present case, the upper primary incisor was avulsed during intubation and, unbeknownst to the anesthesiologist, displaced to the larynx. We report here on the findings and indicate appropriate treatment. Intubation for general anesthesia in children can result in tooth damage and/or dislocation of primary teeth with subsequent root resorption. Prevention is key, and thus it is critical to evaluate the patient's dental status before and after intubation. Furthermore, anesthesiologists and dentists should pay close attention to this risk to prevent any avulsed, dislocated, or otherwise displaced teeth from remaining undetected and subsequently causing serious complications.

A majority of patients who sustain injuries to the peripheral sensory nerves of the face and jaws experience a slow but gradual return of sensation that is functional and tolerable, if not the same as before the injuries. However, long-term effects of such injuries are aggravating for many patients, and a few patients experience significant suffering. In some of these patients, posttraumatic symptoms become pathological and are painful. The predominant painful components are (1) numbing anesthesia dolorosa pain, (2) triggered neuralgiaform pain, (3) burning and aching causalgiaform pain, and (4) phantom pain. This is a case report of conservative management of traumatic neuralgia and neuritis as part of posttraumatic pain syndromes in geriatric patients who have undergone the teeth extraction and alveoloplasty.
