  • 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.

  • In the fracture operation of pan facial fracture, there are many cases where the shape and position of the occlusal and oral structures are abnormally changed because the index for repositioning to the original position is insufficient. And trismus and gag reflex in patients with pan facial fractures increase the difficulty of dental treatment, and the difference in the position of the jaw bone makes it difficult to restore aesthetically and functionally. In this case, digital workflows for minimal intraoral work could be selected to reduce patient discomfort and the difficulty of dental treatment. This case is using a digital workflow from implant planning to final prosthesis production in a patient with acquired skeletal grade III, trismus, and gag reflex due to pan facial fracture 15 years ago. In this case report, the use of digital workflow in a patient who has difficulty in dental treatment was able to minimize patient discomfort and obtain esthetic and functionally appropriate results.
