Multiple myeloma is malignant neoplasm of plasma cells. Mandible lesions are rarely the first symptoms of multiple myeloma. While sensory dysfunction and pain are the main symptoms of traumatic trigeminal neuropathy, the same oral symptoms can appear in cases of multiple myeloma with developed mandible lesions. In addition, if the radiological osteoporosis or lytic lesion is seen in older patients, further examination is required to find the cause of the symptoms. In this paper, we present a case that was tentatively diagnosed as traumatic trigeminal neuropathy after left third molar extraction, but later confirmed as multiple myeloma.

This study was to evaluate the nature of traumatic injuries on anterior teeth of 530 patients and the prognosis of stabilized cases of 102 patients, including possible 18-follow up cases among them, treated at Dental Hospital, Yonsei Medical Center from Mar. 1983 to Feb. 1988. The obtained results were as follows. 1. The peak of monthly distribution of trauma to the anteriors was June and was the lowest in November. The ratio of male to female was 2.6 : 1. The most common incidence of the trauma to the anteriors was seen in the 3rd decades. The most chiefly involved teeth were central incisors in both upper and lower jaws. The causes of trauma were as followed in descending order by first blows, traffic accidents, falls, slip downs, and sports. The types of traumatic injuries of anterior teeth consisted of periodontal tissue injuries(55.9%), the injuries to the hard dental tissues and pulp(31.3%), and alveolar bone injuries(12.8%). 2. 35.1% stabilized anteriors were treated with root canal therapy. The success rate of stabilization was 95.3%, and 92.3% in replantation of avulsed teeth. 3. External root resorption, internal root resorption with calcification of pulp chamber or root canal, ankylosis of root, and other periapical pathosis were seen in follow-up radiographic findings. 4. Success rate of stabilization of the traumatized anteriors after 3 years showed 71.4% average.

Objectives : The purpose of this study was to investigate the maxillofacial injuries of the sports players' and analyzing the concerned factor. Methods : The subject in this study were 290 sports players' enrolled in Jeolla region. SPSS statistics program(Version 12.0) was used to analyzed the collectde data, Chi-square test and percentage were used as the analysis technique. Results : 1. It was found that 63.8% of all respondents ever experienced trauma in sport activities and 28.6% experienced maxillofacial trauma. 2. In terms of traumatic causality, it was found that most of our respondents attributed the biggest cause of maxillofacial trauma to 'sport activities.' 3. However, it was found that only 12.1% of all respondents gave correct answers to question items about good medical treatment for traumatic odontoptosis. 4. It was found that less than half of all respondents ever faced information on maxillofacial trauma. Conclusions : This finding suggests that it is required to build up current orientation programs about maxillofacial trauma for our sport players. The maxillofacial trauma of sport players' is a important factor that degenerate the quality of the oral health and bring about the change of life style.

Prader-Willi syndrome (PWS) is a rare genetic disorder reported rarely in dentistry. Dental practitioners should know the features of PWS because affected patients have a variety of dental symptoms. The current report describes a case of PWS. An 18-year-old male patient presented with traumatic injuries. Initial emergency treatments were performed under sedation, and further treatments were conducted under general anesthesia. After adequate healing, periodic follow-up and dietary management according to the patient's age and nutritional phase were recommended. Dental management of PWS patients consists of active preventive measures in addition to dietary consultation according to age and nutritional phase.

Background: Dental evaluation and protection are important for preventing traumatic dental injuries when patients are under general anesthesia. The objective of the present study was to develop a questionnaire based on dentition-related risk factors that could serve as a valuable tool for dental evaluation and documentation. Methods: We developed a questionnaire for dental evaluation before administration of general anesthesia, investigated the association between patient-and-dentist responses and mouthguard fabrication, and assessed response agreement between 100 patients. Results: Protective mouthguards were fabricated for 27 patients who were identified as having a high risk of dental injury. There was a strong association between dentists' responses and mouthguard fabrication, depending on the general oral health status, use of ceramic prosthesis, presence of masticatory pain related to periodontal diseases, gingival edema, and implants (P < 0.05). Response agreement between patients and dentists for items related to dental pain, loss of dental pulp vitality, root canal therapy, dental trauma, aesthetic prosthesis, tooth mobility, and implant prosthesis was high (Cohen's kappa coefficient κ ≥ 0.6). Conclusions: A high agreement was observed between patient-dentist responses and a strong association with mouthguard fabrication for items pertaining to ceramic prosthesis, masticatory pain, and dental implants. Patients with a "yes" response to these items are recommended to undergo a dental evaluation and use a dental protective device while under general anesthesia.

Traumatic injuries to an immature permanent tooth may result in cessation of dentin deposition and root maturation. Endodontic treatment is often complicated in premature tooth with an uncertain prognosis. This article describes successful treatment of two traumatized maxillary central incisors with complicated crown fracture three months after trauma. The radiographic examination showed immature roots in maxillary central incisors of a 9-year-old boy with a radiolucent lesion adjacent to the right central incisor. Apexogenesis was performed for the left central incisor and revascularization treatment was considered for the right one. In 18-month clinical and radiographic follow-up both teeth were asymptomatic, roots continued to develop, and periapical radiolucency of the right central incisor healed. Considering the root development of these contralateral teeth it can be concluded that revascularization is an appropriate treatment method in immature necrotic teeth.

In an attempt to regain function and aesthetics in the craniofacial region, different biomaterials, including titanium, hydroxyapatite, biodegradable polymers and composites, have been widely used as a result of the loss of craniofacial bone. Although these materials presented favorable success rates, osseointegration and antibacterial properties are often hard to achieve. Although bone-implant interactions are highly dependent on the implant's surface characteristics, infections following traumatic craniofacial injuries are common. As such, poor osseointegration and infections are two of the many causes of implant failure. Further, as increasingly complex dental repairs are attempted, the likelihood of infection in these implants has also been on the rise. For these reasons, the treatment of craniofacial bone defects and dental repairs for long-term success remains a challenge. Various approaches to reduce the rate of infection and improve osseointegration have been investigated. Furthermore, recent and planned tissue engineering developments are aimed at improving the implants' physical and biological properties by improving their surfaces in order to develop craniofacial bone substitutes that will restore, maintain and improve tissue function. In this review, the commonly used biomaterials for craniofacial bone restoration and dental repair, as well as surface modification techniques, antibacterial surfaces and coatings are discussed.
