The purpose of this research is analyzing present condition, and pursuing developmental direction of consultation to department of dentistry for medical inpatient with dental trauma. This research conducted a retrospective analysis of consultation to department of dentistry for medical inpatient at Wonju Severance Christian Hospital from March 2011 to February 2017. This research analyzed chief complaint and dental diagnosis, referring department, time of consultation after dental trauma, relation between hospitalization period and time of consultation after dental trauma, relation between dental trauma and admission in the medical department due to trauma, cause and age of dental trauma occurrence, treatment of dental trauma, and revisiting rate of inpatient with dental trauma after discharge. Among all the chief complaint and dental diagnosis, dental trauma was the highest. Among all the referring departments, departments of surgery were the highest. In relation to being delayed of consultation term after dental trauma, it turned out that there's pretty high mutual relation between the hospitalization period and the consultation term after dental trauma, and the hospitalization period had the quantitative influence on the consultation term. Statistically, dental trauma and admission in the medical department due to trauma had significant relations. In case of those patients due to car accidents, they had dental trauma without exception. Statistically, patient's group with dental trauma in hospital room was younger than patient's group with dental trauma in non-hospital room. Statistically, dental trauma and treatment in hospitalization had no significant relations, and dental trauma and revisiting department of dentistry after discharge had no significant relations. For the child and adolescent inpatients hospitalized for car accidents, there is high possibility of accompanying dental trauma, and dental consultations can be delayed. For the young child inpatients, the possibility of dental trauma occurrence in hospital room is high. Moreover, treatments during hospitalization and revisiting department of pediatric dentistry after discharge are not performed well for inpatients with dental trauma. Regarding these results, it can be an alternative that improving of consultation system, dedicated workforce placement and having dental facilities and equipment in the hospital ward, education to medical doctor and dentist, communication between medical doctor and dentist. This research can be used as a study material of medical and dental departments, and it's expected to be committed to developing of consultations to department of dentistry for child and adolescent inpatients with dental trauma.

This study was designed to evaluate the age, gender, location of trauma, etiology, injury site, types of treatment, elapsed time after trauma, and arrival time of children who visited trauma center of Wonju Severance Christian Hospital. Records of a total of 841 patients who were 0 - 15 years old and received care in the period from March 2011 to October 2015 at the Trauma Center, Wonju Severance Christian Hospital were analyzed. This study showed that traumatic dental injuries were more common in boys and patients between 0 - 3 years old. Under 6 years old, fall was the most common etiology and home was the most common place of trauma. However, fall decreased, and sports and etc increased largely in etiologic factors over 6 years old. Besides, home decreased, and road and kindergarten school increased largely in the place of trauma. Etiology and location of trauma were statistically influenced by the age (p < 0.05). The most commonly affected injury sites were maxillary incisors and lips. The most patients visited trauma center between 18 - 24 o'clock (53.3%), and the least patients visited between 0 - 6 o'clock (4.6%). 51.5% of patients visited the trauma center within 1 hour of sustaining trauma, and 26.8% and 11.5% of patients visited between 1 - 2 hours and 2 - 3 hours respectively. The most common treatment of traumatic dental injuries was observation, and the second most common treatment was suture. Traumatic dental injuries in children exhibit specific epidemiological features according to children's gender, age, and other conditions. These result from combination of social, developmental, and physiologic factors.

The study was conducted to analyze the impacts of COVID-19 on the number of dental trauma patients. Based on the data provided by the Health Insurance Review and Assessment Service's Healthcare Bigdata Hub, dental trauma which occurred from 2010 to 2020 was analyzed. Since the outbreak of COVID-19, the incidence of dental trauma per 100,000 decreased compared to the average Incidence between 2017 to 2019. By age, it decreased by 5.4% (p = 0.017) for 0 - 4 years old, 30.3% (p < 0.001) for 5 - 9 years old, 39.5% (p < 0.001) for 10 - 14 years old, 14.5% (p = 0.002) for 15 - 19 years old, 1.3% for 20 - 29 years old, 0.2% for 40 - 49 years old, 2.7% for 50 - 59 years old, 1.2% for 60 years old or older, but it increased by 2.5% for 30 - 39 years old. Compared monthly, before and after the outbreak of COVID-19 confirmed patients, the number of dental trauma patients dropped sharply. After the outbreak of COVID-19, the incidence of dental trauma decreased significantly for under 20 years old, but the decrease was not significant for 20 years old or older.

치주영역에서의 교합기능은 치주조직의 유지에 필수적이며 교합력이 치주조직의 적응한계를 초과하는 경우 치주조직의 파괴가 유발되며 이러한 현상을 교합성외상, 교합성외상에 의한 병소라고 한다. 교합성외상에 의한 조직파괴양상은 염증성 치주질환과는 많은차이를 보이며 그 원인과 시간에 따라 분류되기도 하며 치주조직의 건강에 영향을 미치는 교합성외상의 영향과 치료과정에 대해 간략하게 살펴보고자 한다.

국소적 소인에 의한 구강내 출혈은 구소적 감염이나 원인 혹은 외상등에 의해 야기되는 것으로 혈액응고에 관여하는 여러인자의 양적, 질적 이상으로 유발되는 출혈성 소인에 의한 출혈과는 구별되어 진다. 대부분의 치과의사가 접할 수 있는 가장 흔한 출혈은 국소적 소인에 의한 것이며, 명심해야 될 사항은 이런 국소적 소인에 전신적 출혈성 소인의 한 요소일 수도 있다는 점이다. 이에 치과의사들은 구강내에서 국소적 원인을 쉽게 발견 치료할 수도 있으나, 전신적 출혈성 소인에 대한 연관성 조사를 항시 염두에 두어야 하겠다. 출혈성 소인에 의한 출혈은 특별한 외상 없이도 되부, 점막, 관절등에 자연히 출혈이 일어나며, 가벼운 외상에 의해서도 쉽게 출혈하는 경향이 있는 점이 국소적 소인에 의한 출혈과의 감별사항이다. 가장 관찰하기 쉬운 곳이 피부 및 점막으로 출혈하여 피가 모인 것을 자반(Purpura)이라 하며, 크기 및 정도에 따라 모세혈관에서의 출혈은 점상출혈(Petechia), 세동맥 및 세정맥에서의 출혈은 반상출혈(Ecchymosis), 좀더 심부에서 출혈하여 촉지되는 혈종(Hematoma)으로 나눌 수 있다. 임상적으로 구별되는 이런 양상을 잘 관찰하고 주의해야 하겠다.

외상의 처치는 일반적으로 응급처치기(emergency 혹은 initial phase), 중간처치기 (intermidiate 혹은 planning phase) 그리고 항구치료기 (definitive phase)로 구분되며 응급처치의 범주내에서는 우선 환자의 생명유지를 고려하고 다음엔 창의 생활력(vitality)을 유지하여 장차의 조직결손과 기능적 결합을 예방하는 데 목적이 있다. 그러므로 구강 및 악안면의 광범한 외상은 기도확보, 대량실혈의 방지, shock의 예방 (수액보충 등) 및 감염대책 등의 순으로 응급대처하게 된다. 그러나 일반 개원임상의들이 자주 접하는 비교적 작은 외상에서는 위의 대원칙에 더하여 창상의 효과적인 1차적 처치에 더욱 관심을 갖어 조직의 괴사나 결손 및 변형으로 인한 기능적 심미적 장애를 최솔 하는 것이 중요하다.

Traumatic bone cyst (TBC) is an asymptomatic lesion seen most in adolescents. TBC is found incidentally on routine panoramic examinations and appears as a relatively well-demarcated unilocular radiolucency with scalloped margins. Histological examination reveals a vacant cavity of cancellous bone usually unlined or very occasionally lined with a thin connective tissue layer. The lack of lining epithelial membrane is common histological feature. The most affected site is between the mandibular canine and third molar. The involvement of the mandibular symphysis is rare. The etiopathogenesis of the TBC is unclear. TBC is treated with surgical exploration and curettage; new bone is formed in place of the lesion within 6 - 12 months of surgery. Diagnosis of TBC prior to surgical intervention has limitations in most of the cases. Both of our patients were diagnosed through radiological examination and biopsy. Neither patient had a history of trauma. After surgery, the panoramic radiograph and CBCT were used to confirm bone healing.

교합의 부조화는 외상성교합을 야기시킬 뿐만 아니라 치태의 침착을 용이하게 하며 일단 침착된 치태의 제거에도 애로점이 있고 외과적으로 치주낭을 제거하기 위한 술식을 적용할 때에도 문제점이 있다. 따라서 교합의 부조화를 치료해주는 교합치료는 완벽한 치주처치를 위한 중요한 한 분야이다. 특히 치주과 영역에서 외상성교합의 처치는 필수적이며, 그 방법도 대단히 다양하다. 외상성 교합의 증상에 따라서 치료방법을 선택하자면 다음과 같다. 우선 치은조직에 치은퇴축 혹은 형태의 이상이 야기되었을 때에는 이에 따라 외과적인 처치가 선행되어야 함은 물론이며 다음 단계가 치아의 위치이상을 교정적인 처치를 통하여 정복하거나 동요치를 안정시켜줄 필요가 있으며 또한 정확한 교합조정술이 필요하다. 교합조정술에 대한 제반 사항과 술식에 대하여는 본지, 1982년도 6월호에 상세히 언급되었으므로 본 원고에서는 교정적인 처치방법과 치주고정장치의 적용에 대하여 기술 하고자 한다.

급격한 치아외상은 치아 경조직에 손상을 주기도 하지만 치수와 치주조직에도 손상을 입힌다. 탈구(luxation)의 경우, 외상에 의해 치근단공 부위에서 신경혈관계의 파괴가 초래되지만 치근파절의 경우에는 파절전 부위에서 이와 유사한 손상이 나타난다. 그러므로 치근파절을 파절선 상부의 치관부에 대한 일종의 탈구로 보기도 한다. 본 증례보고는 외상에 의한 치근파절의 두 가지 치유양상을 비교한 것으로, 한 증례는 특정한 치과적 처치없이 스스로 치유된 경우이고 다른 한 증례는 치아고정 및 근관치료를 포함한 치과치료후에 치유된 경우이다. 수평치근파절의 치유에는 여러 가지 요인이 관여하지만 특히 치아동요도 및 치수생활력이 큰 영향을 미친다. 본 증례에서와 같이 치아의 동요도가 있는 경우에는 고정을 통해서 치유를 촉진하고 치수의 괴사가 초래된 경우에는 근관치료를 포함한 적절한 치과치료를 통해서 치유가 일어날 수 있다. 따라서 치근이 파절된 경우에는 장기간의 관찰을 통해 파절부 치유 및 치수손상 여부를 관찰, 진단하고 그에 따른 적절한 처치를 시행해야 할 것이다.

School nurses can play an important role in improving the prognosis of traumatized teeth of school children when they are informed about the immediate and proper dental first aid steps. The purpose of this study were to assess the awareness of school nurses concerning the management of traumatized teeth and to determine if a lecture on dental trauma management could improve school nurses'knowledge on this topic. School nurses in Gwangju and Jeonnam province completed a questionnaire before and after the lecture on the first-aid knowledge with particular focus on the following three categories. Questionnaires are composed of questions asking general information and about knowledge and proper attitude in case of the specific situation on dental trauma. According to previous studies, school nurses' knowledge tended to be higher compared with the teachers. Improvement of knowledge in school nurse was observed in emergency actions, in visiting time, replantation, carriage method, vaccine prescription related with luxation, and in possibility of fragment reattachment related with subluxation and fracture. In conclusion, it is recommended that periodical education are needed for improvement of school nurses'knowledge on proper management of dental trauma emergency.
