Three cases of treated permanenet teeth are presented. A horizontal root fracture was treated by endodontic treatment in which coronal segment only was done. A replanted incisor is ankylosed because of false restorative method and long extraoral period. Resorption of traumatized bone can be seen in the third case. The prognosis of traumatized incisor depends on proper restoration, adequate amergency treatment and periodic follow-up check.

전신적 또는 국소적 요소에 의하여 유치 치근이 병적으로 흡수될 수 있으며 치아 우식증이나 외상 등으로 염증성 치근 흡수가 발생할 수 있다. 유치의 병적 치근 흡수면은 생리적인 치근 흡수와 비교할 때 흡수면의 세포와 흡수와의 형태 등의 흡수 양상이 다르다. 이 연구는 생리적 치근 흡수, 외상, 염증성 치근 흡수면의 형태 및 인접한 세포를 주사전자현미경과 광학현미경으로 관찰하였다. 생리적 치근 흡수면의 흡수소와는 원형과 타원형이고 비교적 작고 균일하였다. 외상으로 인한 치근 흡수면과 염증성 치근 흡수면의 흡수소와는 생리적 치근 흡수면의 흡수소와에 비해 다각형이며 크고 불규칙하였다. 생리적 치근 흡수면과 외상으로 인한 치근 흡수면, 염증성 치근 흡수면에서 다핵거대세포와 단핵세포가 관찰되었으며 염증성 치근 흡수면에서는 간엽세포 및 염증세포가 많이 분포되어 있었다. 생리적 치근 흡수면과 외상으로 인한 치근 흡수면에서는 흡수 표면에 백악질양 조직이 침착되었으나, 염증성 치근 흡수면에서는 관찰되지 않았다.

Penetrating gallbladder injuries are uncommon in the pediatric population. The treatment varies according to the severity of the injury and the patient's hemodynamics. We present the case of an 11-year-old male with an accidental pellet gunshot wound to the right upper abdomen that resulted in a grade III liver laceration and damage to the anterior gallbladder wall. The patient underwent laparoscopic cholecystectomy with drain placement. Postoperative radiography of the surgical specimen confirmed the presence of the pellet in the gallbladder. The patient recovered uneventfully and was discharged home on postoperative day 3. Laparoscopic cholecystectomy is a feasible treatment option for penetrating gallbladder injuries in hemodynamically stable patients.

교내에서 학생들의 치과적 외상은 흔하며 일반교사들보다 보건교사들이 외상의 일차적인 처치를 담당한다. 본 연구는 광주, 전남지역의 초, 중, 고등학교 보건교사들을 대상으로 어린이들의 치아외상시의 대처 방법에 대한 지식수준을 조사하고, 치과 응급처치에 대한 교육을 시행한 후 그 효과가 어느 정도인지를 알아보고자 하였다. 본 연구에 참여한 보건교사는 194명으로 치아외상교육 전후에 설문지를 배분하였다. 설문지는 일반적인 사항, 치아외상이 일어난 상황에서의 태도 및 지식에 관한 질문을 포함하고 있다. 치과 응급처치 교육을 시행한 후 적절한 응급처치, 치아의 완전 탈구 시에 치과 내원시간, 재식여부, 치아 운반방법, 파상풍백신 접종여부와 치아 아탈구 및 파절시의 파절편의 재접착 가능 여부 및 처리법에 관한 항목에서 보건교사들의 응급처치에 대한 지식수준이 향상되었다. 따라서 보건교사의 치과적 응급처치에 관한 지식수준향상을 위한 주기적인 교육의 시행이 요구된다.

Recurrent meningitis in children is not only a potentially life threatening condition, but often involves the child in the trauma though repeated hospital admissions and multiple invasive investigations to find the underlying causes. Symptoms and signs of CSF rhinorrhea or otorrhea are infrequent in these patients and difficult to diagnose in young children. All young children treated for meningitis should then be administered an evoked potential audiometry as a post-treatment test. If sensorineural hearing loss is identified, the clinician should be alerted to the possibility of CSF leakage as the cause of the meningitis. Radiologic studies should be performed to rule out preexisting congenital, or acquired, abnormalities requiring surgical exploration. Two young children with recurrent meningitis due to a right cochlear aplasia and a cribriform plate defect caused by trauma are presented to illustrate the problems of diagnosis and management. A review of literatures will also be presented briefly.

Purpose: Trauma is one of the most common causes of death for children, and identifying severely injured children quickly in an overcrowded emergency room (ER) is difficult. Therefore, severe injury must be prevented, and the severity of injuries in children must be determined easily from their general characteristics and pre-hospital factors. Methods: Injured children younger than 15 years of age who visited the ER from June 2011 to May 2013 were enrolled. According to the revised trauma score (RTS) of the patients, the study population was divided in two groups, a severe group (RTS<7) and a mild group ($RTS{\geq}7$). The general characteristics and the pre-hospital factors were compared between the two groups. Results: Six hundred seventy-three children were enrolled, their mean age was 8.03 (${\pm}4.45$) years, and 476 (70.73%) patients were male. Of these patients, 22 patients (3.27%) were in the severe group, and 651 patients (96.73%) were in the mild group. Fewer males were in the severe group than in the mild group (50.00% vs. 71.43%, p=0.030), and children in the severe group were younger than children in the mild group (3.50 vs. 8.00 years, p=0.049). In the severe group, toddlers (54.55%, p=0.036) were the most common age group. Severe injuries occurred more often in spring (32.81%) and summer (54.56%) than in autumn (9.09%) and winter (4.55%) (p=0.026). The most common places of injury in the severe group were roads (50.00%, p=0.009), and the most common mechanisms of injury in the severe group were traffic accidents (50.00%), followed by falls (31.82%) (p=0.011). Most severely injured children were transferred by ambulance (72.73%, p=0.000). Conclusion: The results of this study may be helpful for identifying severely injured children quickly in the field and the ER. To prevent severe pediatric injuries, precautions and policies based on these results should be established.

Pediatric pancreatitis is not uncommon and results in considerable morbidity and mortality in the affected children. Unlike adults, pediatric pancreatitis is more frequently associated with underlying structural abnormalities, trauma, and drugs rather than an idiopathic etiology. Magnetic resonance cholangiopancreatography (MRCP) is a good imaging modality for evaluating pancreatitis and determining etiology without exposure to radiation. This article focuses on MRCP findings associated with various causes of pancreatitis in children, particularly structural abnormalities of the pancreaticobiliary system, as well as describing the feasibility, limitations, and solutions associated with pediatric MRCP.

Purpose: 'White-eye blowout' fracture is often occur in young patients and defined as blow out fracture with little or no clinical sign of soft tissue trauma such as edema, ecchymosis, but with marked motility restrictions in vertical gaze. In this conditions, immediate operation is essential. We reported the clinical investigation study of these cases about clinical symptoms and radiologic findings and introduce our experiences about immediate operations in 'white-eye blowout' fractures. Methods: From January 2008 to December 2009, nine pediatric patients who were diagnosed as pure white-eye blowout fractures were involved this study. Patients with other facial bone fractures or with poor general medical condition were excluded. In all cases, we performed immediate operation within 48 hours. Results: All patients had diplopia, vertical gaze restriction or systemic symptoms. Six patients had nausea, vomiting and syncope caused by oculocardiac reflex. In all patients, preoperative symptoms were improved after immediate operation. There were no postoperative complications such as infection, hematoma or wound dehiscence. Conclusion: When we meet the young patients with history of periocular trauma, with little or no soft tissue trauma signs, but with marked vertical gaze restriction or general symptoms caused by oculocardiac reflex, we should immediately examine by facial bone computed tomography and refer the patient to ophthalmologist for ophthalmic evaluations. If patient is diagnosed as orbital floor fracture with entrapped muscle or soft tissue, the earlier surgical reduction get better clinical outcomes.

Children who have severely destructive anterior primary dentition, as in nursing-bottle caries, in trauma, in rampant caries and in developmental defects, present the dentist with one of the most perplexing situations in dentistry. Especially, children with managed behavor difficultly is very severly situations. This paper reported a new technique for the utilization of resin post and strip crown to indirect methods on severely destructive primary anterior teeth. We name it "indirect short resin post crown" in this paper. Indirect technique be considered to be a simple, a retentive, intensive, color-stable and esthetic restoration.

과잉치는 정상 치판의 과도한 증식의 결과로 발생하고, 주로 상악 전방부에서 많이 발견되며 이것을 정중과잉치라 칭한다. 정중과잉치의 존재 시 영구 전치의 위치 이상, 정중이개, 낭종의 형성, 구강 및 비강 내로의 맹출 등과 같은 다양한 문제가 존재하게 되므로 발거하는 것이 일반적이다. 본 증례는 외상으로 인해 편측 상악 중절치를 조기에 상실하였고, 매복된 상악 정중과잉치를 가지고 있는 9세 8개월된 남아로, 정중과잉치를 상실된 상악 중절치 부위에 자가이식한 후 보철적으로 수복하여 치조골 흡수를 막고 심미적인 수복을 도모한 증례이다. 이 증례에서 과잉치는 총 길이 14mm로 지대치로 사용하기에는 크기가 작고 치관/치근 비율도 좋지 않아 예후가 불량할 것으로 예상하였으나, 시술 후 8개월의 관찰 기간 동안 양호한 결과를 나타내어 이에 보고하는 바이다.
