외상으로 인해 치근 완성 여부가 불분명 한 완전 탈구된 치아를 재식한 후 18개월 여간 관찰하여 다음과 같은 결과를 얻었다. 1. 재식 초기의 염증성 치근 흡수는 수산화 칼슘을 사용한 근관치료로 억제될 수 있었다. 2. 치근 완성 여부가 불확실한 치아에서 조기 근관치료가 염증성 치근 흡수 및 유착의 방지에 더 큰 임상적 성공을 얻을 수 있었다. 따라서, 재식 당시 치근첨의 개방성 여부가 명확하지 않을 때에는 성인의 치료 지침에 따라 치료하는 것이 보다 효과적이며, 불가피 할 경우에는 환자 및 보호자의 철저한 교육에 뒤따른 정확한 내원 약속이 속발증을 최소화 할 수 있을 것으로 사료된다.

Dentoalveolar (DA) trauma, which can involve tooth, alveolar bone, and surrounding soft tissues, is a significant dentofacial emergency. In emergency settings, physicians might lack comprehensive knowledge of timely procedures, causing delays for specialist referral. This systematic review assesses the literature on isolated DA fractures, emphasizing intervention timing and splinting techniques and duration in both children and adults. This systematic review adhered to PRISMA guidelines and involved a thorough search across PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library from January 1980 to December 2022. Inclusion and exclusion criteria guided study selection, with data extraction and analysis centered on demographics, etiology, injury site, diagnostics, treatment timelines, and outcomes in pediatric (2-12 years) and adult (>12 years) populations. This review analyzed 26 studies, categorized by age into pediatrics (2-12 years) and adults (>12 years). Falls were a common etiology, primarily affecting the anterior maxilla. Immediate management involved replantation, repositioning, and splinting within 24 hours (pediatric) or 48 hours (adult). Composite resin-bonded splints were common. Endodontic treatment was done within a timeframe of 3 days to 12 weeks for children and 2-12 weeks for adults. Tailored management based on patient age, tooth development stage, time elapsed, and resource availability is essential.

목적: 본 연구의 목적은 탄성력이 높게 개발된 레진의 굽힘 강도를 평가하고, resin wire splint (RWS)와 유연성을 비교 평가하는 것이다. 재료 및 방법: 세가지 레진 G-aenial flo (GA, GC), Superbond (SB, Sun medical), G-fix (GF, GC)의 세 점 굽힘 강도는 ISO4049/2000에 따라 진행하였다. GA, SB, GF를 이용한 세개의 RS군과 GA와 교정용 016" SS wire를 이용한 RWS군간의 치아 동요도 비교는 영구치 모형을 이용하였다. 상악좌측중절치에 3도의 동요를 부여하고, 치아의 수평적인 동요도를 splint 전후에 각 3회씩 periotest vale로 평가하였다. Splint 전후 periotest value는 splinting 효과로 환산하여 평가하였다. 통계적인 평가는 one-way ANOVA와 turkey HDS test를 이용하였다(${\alpha}=.05$). 결과: SB와 GF가 GA에 비해 낮은 굴곡강도를 보였으나, 세가지 RS군은 RWS에 비해 높은 splinting 효과를 나타내었다 (P < .05). 결론: 제한된 본 연구에서 사용된 재료와 상관없이 RS는 RWS에 비해 높은 견고성을 보였으며, 이는 탈구치아 치료를 위한 flexible splint에 부적합한 것으로 보인다.

정중이개란 상악 중절치 사이의 치간이개를 말한다. 이는 혼합 치열기에서 ugly ducking stage에 흔히 관찰할 수 있으며 일반적으로 견치가 맹출하면서 자연적으로 소실되므로 꼭 치료가 필요한 것은 아니다. 그러나 견치 맹출 후에도 정중이개가 2mm이하로 계속 존재하거나 견치 맹출 전이라도 3mm이상의 정중이개가 존재하는 경우에서는 치료의 적응증이 될 수 있다. 특히 후자의 경우 심미적인 면에서 뿐만 아니라, 이로 인해 측절치와 견치의 맹출공간이 부족해지는 문제가 발생하므로 교정치료가 권장된다. 정중이개 치료시 사용되는 장치물은 finger spring 등을 이용한 가철성 장치물과, 교정용 band, tube, bracket 등을 부착시켜 rubber elastics이나 coil spring 등을 사용하는 고정성 장치물로 나뉘어진다. 그러나 정중이개의 치료를 위해 rubber band를 band, tube, bracket 등과 같은 적절한 부가장치 없이 사용하면 rubber band가 치근은 따라 치은 하방으로 이동하게 되고 치주 인대를 파괴하며 치근단 부위에 이르러 치아동요, 치아정출 및 탈락 등 치아에 치명적인 손상을 입힐 수 있다. 본 증례는 정중이개의 치료를 위해 부적절하게 rubber band를 사용하여 외상을 받은 치아를 관찰하여 다소의 지견을 얻었기에 이를 보고하는 바이다.

A material of 48 patients with 60 avulsed and replanted permanent teeth were followed retrospectively in the period of 1996. 1 to 1998. 12 (mean observation period=1year 7months). The age of the patients at the time of replantation ranged from 9 to 63 years (mean=24 years). Clinical records of patients were reviewed to obtain valid data concerning the extent of injury and treatment provided. Pulpal and periodontal healing states were examined with periapical x-rays and clinical examination procedures (i.e. percussion test and mobility test) at their recall visit. Root ankylosis was found in fifty-two teeth(87%) and root resorption in twenty-four(40%). Only two of the replanted teeth(3%) showed partial regeneration of the periodontal ligament. Six teeth(10%) resulted in tooth loss, but the remaining fifty-four were clinically well functioning. Most of teeth have mild marginal bone loss accompanied by gingival retraction without pathological periodontal pockets. The incidence of root resorption was much higher in younger age group. However, it was not affected by the interval between avulsion and replantation, the condition of supporting tissues, the degree of root formation and the type of splinting, indicating that multiple factors involved in determining the prognosis of replanted teeth. Based on these findings, avulsed teeth in unfavorable conditions (i.e. long extra-alveolar periods, etc.) should be preserved if possible.

Invasive cervical resorption is a relatively uncommon form of external root resorption. It is characterized by invasion of cervical region of the root by fibrovascular tissue derived from the periodontal ligament. This case presents an invasive cervical resorption occurring in maxillary lateral incisor, following damage in cervical cementum from avulsion and intracoronal bleaching procedure. Flap reflection, debridement and restoration with glass ionomer cement were performed in an attempt to repair the defect. But after 2 mon, more resorption extended apically. Considering root stability and recurrence potential, we decided to extract the tooth. Invasive cervical resorption in advanced stages may present great challenges for clinicians. Therefore, prevention and early detection must be stressed when dealing with patients presenting history of potential predisposing factors.

Introduction: In today's society, the rapid and appropriate care of the dental emergency patients is much more important. So, a retrospective study on the characteristics of emergency dental injuries and diseases will be very meaningful. Materials and Methods: This retrospective clinical study was carried by reviewing the radiographic films and emergency chart of 11,493 patients who had visited the emergency room of Hallym Sacred heart Hospital and were treated in the Department of Oral and Maxillofacial Surgery from January 2006 to December 2010. Results: The male to female ratio was 1.9:1. The highest monthly incidence was observed in May (10.4%) and June (8.9%) and the peak age distribution was the first decade (56.0%), followed by the second decade (16.0%). Trauma was the most common cause in dental emergency patients, followed in order by toothache, odontogenic infection, temporomandibular joint (TMJ) disorder and oral hemorrhage. Soft tissue injury was most prevalent in the trauma group, followed by tooth injury and facial bone fractures. In the tooth injury group, tooth fracture (56.7%) showed the highest incidence followed in order by tooth subluxation (18.2%), tooth concussion (16.9%), tooth avulsion (11.5%) and alveolar bone fractures (3.7%). In the facial bone fracture group, mandibular fractures (81.8%) showed the highest incidence followed in order by maxilla fractures (15.7%), nasal bone fractures (9.0%), zygomaticomaxillary complex fractures (5.4%), orbital bone fractures (2.5%). In mandibular bone fractures, the most common location was the symphysis (70.1%), followed in order by the mandibular angle (33.0%), mandibular condyle (22.8%) and mandibular body (13.6%). In the infection group, a submandibular space abscess (46.2%) was most common followed in order by a buccal space abscess (17.4%), canine space abscess (16.9%) and submental space abscess (12.3%). TMJ dislocation (89.3%) showed the highest incidence in the TMJ disorder group, followed by TMJ derangement (10.7%). In the other group, a range of specific symptoms due to post operation complications, trigeminal neuralgia, chemical burns and foreign body aspiration were reported. Conclusion: For the rapid and appropriate care of the dental emergency patients, well-organized system should be presented in oral and maxillofacial surgery. And it is possible under analysis of pattern and the variation of the dental emergency patients.
