Primary intraosseous carcinoma (PIOC) is a rare odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw having no initial connection with the oral mucosa, and probably developing from residues of the odontogenic epithelium. PIOC appears more common in male than female, especially at posterior portion of the mandible. Radiographic features of PIOC show irregular patterns of bone destruction with ill defined margins. It could be sometimes misdiagnosed as the cyst or benign tumor because it shows well defined margins. If it couldn't be done appropriate treatment initially, PIOC shows extremely aggressive involvement, extensive local destruction and spreads to the overlying soft tissue. Therefore accurate diagnosis in early state is necessary. The diagnosis criteria proposed for PIOC are : (1) absence of ulcer formation, except when caused by other factors, (2) histologic evidence of squamous cell carcinoma without a cystic component or other odontogenic tumor cell, and (3) absence of another primary tumor on chest radiograph obtained at the time of diagnosis and during a follow-up period of more than 6 month(Suei et al., 1994).

Purpose: To research about maxillofacial traumatic injuries of children in aspects of gender difference, various incidence rates between age, trauma type, cause, monthly and daily incidence rate, type of tooth damage, gingival damage, soft tissue damage, and type of facial bone fracture. Materials and methods: Study group consisted of children under 15 years of age who visited Dental Hospital, School of Dentistry, Kyung Hee University from 2004/7/1 to 2007/6/30 with chief complaint of oral and maxillofacial traumatic injuries. 1,559 cases of traumatic injuries were studied from 1,556 (1,004 male, 552 female) children. Conclusion: 1. There were slightly more boys than girls, giving a male-to-female ratio of 1.82:1.0. The 1-3 year old boys and girls had the highest number of traumatic injuries. 2. Of the 1,556 patients, 68.63% had soft tissue injuries, 50.22% had periodontal injuries, 29.89% had teeth injuries, and 3.85% had maxillofacial bone fractures. 3. Falling down was the most common cause of injury in both sexes. 4. The months with the highest incidence rates were in order May (12.12%), June (11.74%), and October (11.13%). Most of the injuries occurred on weekends. 5. The most common tooth injury was uncomplicated crown fracture, and the most common periodontal injury was subluxation. The majority of traumatizes teeth were the upper central incisors. 6. The most common soft tissue injury was intraoral lacerations. 7. Mandibular fractures were most frequent in facial bone fractures; symphysis, condylar head, and angle fractures were most frequent in mandibular fractures; maxillary and nasal bone fractures were most frequent in midfacial bone fractures.

법랑질 형성부전증은 전치부 개교합과 같은 골격적인 문제를 자주 동반하며, 이러한 경우 구강악안면외과, 보철과, 보존과, 교정과 의사들이 함께 치료하여야 한다. 본 증례는 법랑질의 약화와 치아 우식증 등의 이유로 일반적인 교정치료를 시행할 수 없어 보철적 방법으로 치료하였다. 보존적, 보철적 방법을 이용하여 술전 교정과 같은 안정된 교합을 형성하였다. 악교정 수술을 시행하고 SAS 등을 이용하여 악간고정을 시행하여 양호한 결과를 얻을 수 있었다. Amelogenesis imperfecta (AI) is a hereditary disease that affects enamel formation. The patients with AI have esthetic and functional problems due to damage of multiple teeth. So most AI patients resolve these problem through the conservative and prosthodontic treatments. In our case, It was difficult to obtain good results in means of conservative and prosthodontic treatments, because the AI patient had skeletal Class III malocclusion. Moreover, because of vertical dimension loss due to severe dental caries and maxillofacial skeletal disharmony, the ordinary prosthodontic treatment was troublesome. So we planned orthognathic surgery to resolve these problems. After the endodontic treatment, temporary restoration was delivered for stable post-operative occlusion. Then orthognathic surgery was done, and final restoration was delivered in stable period. We obtained satisfactory results in esthetic and functional aspects through multidisciplinary management(conservative treatment, prosthodontics and orthognathic surgery).

청소년의 품행장애와 반항성 장애에서 보이는 우울증상과 연관된 특성

Objectives:Externalized behavioral problems are prevalent in adolescents, due to the difficulties associated with this developmental stage. Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD), as well as other psychiatric disorders, such as major depressive disorder, result in the manifestation of many behavioral problems during adolescence. Methods:For this report, we analyzed a sample of 31 adolescents, each of whom had presented with CD or ODD at Chosun University Hospital between 2002 and 2010. We separated subjects into depressed and non-depressed groups according to their Beck Depression Inventory scores (BDI<10, non-depressed ; BDI≥10, depressed). Then we analyzed for neuropsychological differences between the depressed and non-depressed groups. Results:In our sample, adolescents in the depressed group showed less of a stealing (deceitfulness and/or theft) behavioral pattern and presented with more anxiety symptoms, lower self-esteem, and greater sensitivity in interpersonal relationships, as compared to the non-depressed group. Conclusion:When adolescents exhibit disruptive behavior, clinicians should consider the underlying causes of the behavior.
