Purpose: Dental avulsion injuries have a poor prognosis that largely depends on the immediate steps taken to manage the avulsed tooth. A lack of knowledge about the initial management can lead to tooth loss, with further adverse implications for esthetics, phonetics, and overall growth and function. Hence, the present study aimed to assess parents' knowledge regarding dental avulsion and the variables associated with their knowledge of avulsion injuries. Methods: A series of closed-ended questions on parents' knowledge regarding avulsion, such as immediate management, storage media, handling, and urgency of visiting the dentist, was asked. Univariate associations between the outcomes were assessed using the Pearson chi-square test. The chisquare goodness-of-fit test was used to check whether the sample data were representative of the population. Results: In total, 211 mothers and 149 fathers were included, of whom 46.7% had experienced dental trauma during their own childhood. Sixty-one percent of mothers believed that they knew everything necessary about tooth avulsion and its management. A significant number of participants who thought that they had a good level of knowledge about avulsion chose water, tissue, or paper wrap to transport the tooth, and preferred tap water, alcohol, or antiseptic to clean the avulsed tooth. Conclusions: Both mothers and fathers had poor knowledge about tooth avulsion, indicating that there is an immediate need for educational programs focusing on this issue. Since a substantial proportion of participants believed incorrect information, it is vital to disseminate accurate information.

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.

외상으로 인해 완전 탈구와 함입성 및 정출성 탈구가 병합되어 나타나는 경우는 드물다. 2003년 7월에 10세 2개월의 여아가 상악우측 측절치의 완전탈구와 상악우측 중절치의 함입성 탈구, 상악 좌측 중절치의 정출성 탈구로 전남대학교병원 소아치과에 내원하였다. 내원 당일 외상치아를 외과적으로 재위치시켰으며 레진 강선 고정을 시행하였다. 외상 2주 후 완전탈구된 상악우측 측절치는 근관치료를 시행하였다. 외상 3개월 후 방사선사진 상에 상악 좌우측 중절치의 치근 외흡수가 관찰되었으며 수산화칼슘을 이용한 근관치료를 시행한 후 치근 외흡수가 정지되었다. 1년 4개월 동안의 관찰기간 동안 병적인 변화 없이 양호한 결과를 보였으며 추후 장기적인 추적관찰이 필요하리라 사료된다.

Traumatic dental injury can result in avulsion of anterior teeth. In young patients, it is a challenge to the dental professional because after replantation, late complications such as ankylosis require tooth extraction. Although prosthetic and orthodontic treatment, and implant placement have been described as the options for intervention, autogenous tooth transplantation could be an effective procedure in growing patients if there is a suitable donor tooth available. This case presents the treatment of a patient who suffered a traumatic injury at 9 years old with avulsion of tooth 21, which had been replanted, and intrusion of tooth 11. Both teeth ankylosed; thus they were removed and autotransplantation of premolars was carried out. After transplantation, the tooth underwent root canal treatment because of pulpal necrosis. Orthodontic treatment began 3 months after transplantation and during 7 years' follow-up the aesthetics and function were maintained without signs of resorption.

치아의 완전 탈구는 치조골에서 치아가 완전히 이탈된 것으로 정의되며, 결과적으로 신경혈관 공급의 중단을 야기하는 가장 심각한 치과적 손상 중 하나로 알려져 있다. 완전 탈구는 조직 허혈(tissue ischemia)을 야기하며, 이는 치수 괴사를 초래할 수 있다. 치근단형성술(apexification)은 치수 괴사로 진단된 미성숙 영구치에서 치근단 장벽을 유도하는 전통적인 치료 방법이다. 하지만 치근단형성술로는 치근 길이 및 두께의 증가를 포함하는 치근 발육을 얻을 수 없다. 본 증례는 완전 탈구되어 재식된 이후 치수 괴사로 진단된 치아를 가진 5세 환자에서 ciprofloxacin, metronidazole, cefaclor 및 CollaTape과 Biodentine을 이용하여 시행된 치수재생치료(regenerative endodontic treatment)의 임상적 및 방사선학적 결과를 다루고 있다.

외상에 의한 영구치의 손상은 유치열에서 영구치열로 이환되는 $8{\sim}10$세 경에 가장 빈발하며, 치아의 파절, 전위 함입, 정출, 탈구 등일 나타난다. 이중 치아가 치조와에서 이탈되는 손상을 받았을 경우에는 일반적으로 원래의 치조와내에 이탈된 치아를 재위치 시키고 고정하여 치유를 도모한다. 본 증례는 원광대학교 치과병원에 내원한 2명의 환아로 외상을 받은 후 각각 다른 기관에서 응급처치를 받았으나, 적절히 정복되지 못하여 본원에 내원 시 조기접촉을 보이고 있었다. 이에 고정된 치아를 다시 탈구시켜 원래의 치조와내에 재식하고 고정하였다. 적절하지 못한 재식은 지속적인 교합접촉을 일으킬 수 있으며, 이로 인한 치유의 지연 및 저작곤란, 부정교합 등을 야기할 수 있다. 외상 환자를 가장 먼저 접하게 되는 응급실이나 의원에서는 외상치의 처치에 대하여 숙지하고 있어야 하며 적절한 의뢰가 이루어져야 한다.

Objectives: This analysis details the characteristics of dental trauma in South Korea during the coronavirus disease 2019 (COVID-19) (DC) pandemic and compares them in patients before and after COVID-19 (BC and AC, respectively). Materials and Methods: Data were collected from medical records of patients who visited Seoul National University Bundang Hospital's Emergency Dental Care Center during three 12-month periods: BC, DC, and AC (BC from March 1, 2019 to February 29, 2020; DC from March 1, 2020 to February 28, 2021; AC from March 1, 2022 to February 28, 2023). A retrospective review was conducted to investigate patient age, sex, time of visit, cause, and diagnosis. The study included 1,544 patients: 660 BC, 374 DC, and 510 AC. Results: Significant difference in age and sex was not observed among the three periods; 1-9 years of age was the largest group (38.3% in BC, 29.6% in DC, and 27.8% in AC), and the percentage of male patients was greater than of female patients (male proportion as 63.5% in BC, 67.4% in DC, and 64.9% in AC). The number of patients generally peaked at a Saturday night in spring (for BC: May, Saturday, 18:00-19:59; for DC: March, Saturday, 18:00-19:59; for AC: April as the second most (October as the most peaked), Saturday, 20:00-21:59). The primary etiology of the dental trauma was identical in the three periods: falls, followed by sports. The most frequent diagnosis was laceration, followed by tooth avulsion and jaw fracture. Conclusion: Significant differences were not found between the characteristics and patterns of dental trauma in the BC, DC, and AC periods. However, due to the pandemic and social distancing, activities decreased and associated dental trauma-related incidents declined.

Recently dental emergency patients tend to increase and diversify because of increased living quality and acknowledgement of health care. We performed this study to understand the pattern of dental emergency and perform the adequate diagnosis and treatment. From August 1998 to July 1999, we inverstigated the rate of dental emergency, distribution according to disease pattern, monthly distribution, and types of emergency treatment from all the emergency patients that visited emergency medicine of Daejin Medical Center, Jesaeng Hospital. There were 266 dental patients(0.978%) from total 27,192 emergency patients. Types of emergency situations included lip lacerations, teeth fracture, teeth missing or avulsion, TMJ contusion, mandible fracture, tongue laceration, toothache, teeth luxation, and so forth. Dental emergency had highest frequency in July. The most common treatments included primary closure of soft tissue lacerations, fixations of luxated teeth and medications.

Management of maxillofacial trauma includes primary care, in which diagnosis and management of dentoalveolar injury play a vital role. Due to the impact sustained during a maxillofacial injury (whether direct or indirect), dentoalveolar injuries can occur, leading to fracture and displacement of teeth and associated alveolar bone into the surrounding soft tissues and associated structures, such as the maxillary sinus, nasal cavity, upper respiratory tract, tracheobronchial tree, or gastrointestinal tract. Undiagnosed displaced teeth may cause complications such as airway obstruction. This paper reports a case of displaced teeth in the nasal cavity and gastrointestinal tract and highlights the management protocol for displaced teeth secondary to maxillofacial trauma.
