  • The appropriate care to the dental emergency patients is much important in the aspect of community dental service. To attain such a purpose, the sacred duty of the training of oral and maxillofacial surgeons is required. So, a retrospective study on the characteristics of dental injuries and diseases in emergency care unit will be very meaningful. This study was carried by reviewing the charts and radiographic films of 3,394 patients, treated for dental emergency at Wonju Christian Hospital, Republic of Korea, from January 1, 1993 to December 31, 2002. All patients were classified to 6 groups including trauma, toothache, infection, hemorrhage, TMJ disorder and the others. The clinical characteristics of diseases and treatment modalities according to each group were analyzed. The trauma (73.9%) was the most frequent cause in dental emergency patients, and acute toothache, odontogenic infection, oral hemorrhage, and TMJ disorder were next in order. Gender prediction was male (68%), there were many patients on May and December in the monthly frequency, and the most frequent age group was from 0 to 9 years. In the trauma group, male (68.6%) was predominant, and soft tissue injuries and primary closures were the most frequent type of injury and treatment. In jaw fractures, traffic accidents were the most cause and the weakest site was mandibular symphysis area, and mandibular angle, condyle, and body area were next in order. In the acute toothache group, the cause was dental pulpitis mostly and treatment for that was drug administration mainly. Buccal space abscess in infection group had the largest incidence (24.5%), and common treatments were incision and drainage and medications. In the hemorrhage group, a major cause was postoperative bleeding (60.3%) and hemostasis was obtained by pressure dressing, curettage and suture. For the TMJ disorder group, the peak incidence (63.8%) was shown in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medication such as analgesics and sedatives. In the other group, the various specific symptoms were complained due to acute sialadenitis, trigeminal neuralgia, acute stomatitis, chemical burn, terminal stage neuritis of head and neck cancer, and foreign body aspiration. In conclusion, for the rapid and proper care of the emergency dental diseases, well-trained education should be presented to the intern and resident course of oral and maxillofacial surgery. And it is demanded that oral and maxillofacial surgeons must be prepared in knowledge and skill for such emergency care.

  • Objectives : Osteoporosis is a systemic skeletal disease that decreases bone density and increases the risk of fractures. Bisphosphonates and SERMs are mainly used to treat osteoporosis, but, long-term use increases the risk of side effects such as jaw bone necrosis and breast cancer. Therefore, it is necessary to develop a therapeutic agent for a natural product with few side effects. Water extract of Lonicerae Japonicae Flos (wLF) was mainly found to have anti-cancer and anti-inflammatory effects. However, the effect of wLF on osteoporosis has not been elucidated. Therefore, this experiment investigated the effect of wLF on osteoclasts, osteoblasts and osteoporosis models. Methods : In order to study the effect of wLF on osteoporosis, the OVX-induced rat model was used for in vivo study. After 8 weeks, we measured body weight, uterine weight, liver weight, femur weight, bone density, trabecular area and tibia ash weight. To determine the effect of wLF on osteoclast differentiation, we measured the number of TRAP-positive cells and TRAP activity. To examine the effect of wLF on the expression of osteoblast-related genes, we measured the mRNA expression of alkaline phosphatase (ALP, Alpl) and osteocalcin (OCN, Bglap2). Results : In vivo experiment, wLF inhibited the reduction of femur weight, trabecular area, bone density and tibia ash weight. In vitro experiment, wLF had no significant effect on osteoclast differentiation. However, wLF increased the mRNA expression of Alpl and Bglap2 in MC3T3-E1 cell. Conclusions : This result suggested that wLF may be used for the treatment and prevention of postmenopausal osteoporosis.

  • 다발성 안면 골절의 경우 골절 부위를 원위치로 정복하기 위한 지표가 부족하기에 골절편의 정복 후 교합과 구강 구조의 형태 및 위치가 비정상적으로 변화된 결과를 보이는 경우가 많이 나타난다. 그리고 다발성 안면 골절환자에서 나타난 개구제한과 구역반사는 치과치료의 난이도를 높이고, 외상으로 인한 악골의 위치차이가 심미적, 기능적 회복을 어렵게 한다. 이러한 경우 환자의 불편감과 치과치료의 난이도를 줄이기 위해 최소한의 구내작업을 위한 디지털 워크플로우를 선택할 수 있다. 본 증례는 15년전 발생한 다발성 안면골절로 인한 후천적인 골격성 III급 및 개구제한, 구역반사를 가진 환자에서 상악 전치부 무치악 상태를 임플란트 계획부터 최종 보철물의 제작까지 디지털 워크플로우를 이용하여 수복한 증례이다. 이러한 치과치료의 어려움이 있는 환자에서 디지털 워크플로우의 사용이 환자의 불편감을 최소로 하고 심미적, 기능적으로 적절한 결과를 얻었기에 이를 보고하는 바이다.
