Objective : Trauma has been a controversial issue although it has been considered to be a major factor for the temporomandibular disorder(TMD). We evaluated the relationship between macrotrauma or microtrauma and TMD. Methods : This study was performed in patients with TMD undergoing treatment at SNUBH from October 2006 to January 2007. Sixty one male patients and 166 female patients(total 227) were included and the average age was 34 years(ranging from 14 to 85 years). We investigated the possible etiologic factors, diagnosis and treatment with the review of medical records and radiography. Chronic pain, depression, somatic score(including pain item), somatic score(excluding pain item) were evaluated on the basis of diagnostic index from the Research Diagnostic Criteria on TMD. Results : Eighteen patients(7.9%) out of 227 patients suffered from TMD as a result of macrotrauma. Ninety four(41.4%) patients had microtrauma and six patients(2.6%) had both macro- and microtrauma(etiologic factor). The main symptoms included pain. joint noise and mouth opening limitation while the other symptoms were headache and tinnitus. The patients had suffered from TMD for average 41 weeks (ranging from 1 to 480 weeks). 116 patients took splint as a major treatment. As a prognosis, 19 patients(8.4%) recovered completely. 26(11.0%) had improvement and 181(80%) had persistent symptoms. 1 patient(0.4%) underwent an arthroplasty. Diagnostic index from RDC chart showed that macrotrauma was the highest score(except depression score) among the other etiologic factors. Conclusion : This study showed that macro- and microtrauma can be considered to be the major etiologic factors of TMD, which also affect the chronic, depression and somatic discomfort.

Purpose: The purpose of this study was to evaluate the histological healing process of 3 different types of xenogenic tooth bone graft material and xenogenic bone graft material. Methods: Three types of human tooth bone graft material (chips, crowns, and roots) and BioOss (Geistlich Pharma AG, Wolhausen, Switzerland) was filled at the preformed 4 round-shaped calvarial bone defects of beagle dogs. The beagles were sacrificed at 2, 4, 8, and 12 weeks, respectively, for radiological and histological evaluation. Results: Increased strength and radiopacity were detected in all graft material groups in time-dependent manner. New bone was formed and matured surrounding the graft material histologically. Also, a new bone was directly integrated with graft material. Conclusion: It was expected that newly developed tooth bone graft material would show good bone healing capacity if it was used as a graft material for the restoration of bony defect.

목 적: 본 연구의 목적은 폐쇄성수면무호흡증으로 하악 전방이동장치 치료를 시행한 환자들에게 하악전방이동장치의 유용성을 확인하고, 하악전방이동창치 치료시 하악의 전방이동량이 미치는 영향을 평가하고자 하였다. 방 법: 2007년 1월부터 2009년 2월까지 코골이 및 수면무호흡을 주소로 분당서울대학교병원에 내원하여 야간수면다원검사를 통해 폐쇄성수면무호흡증으로 진단받은 환자 중에서, 치료법으로 하악전방이동장치를 선택한 총 86명의 환자를 후향적으로 평가하였다. 임상기록과 수면다원검사를 포함한 모든 환자의 자료를 검토 및 분석하였다. 결 과: 총 86명의 환자 중 65명(75.6%)에게서 성공적인 결과를 얻었다. 경과관찰 기간 중에 28명의 환자에게서 경미한 전치부와 턱관절의 불편감이 보고되었으며, 특히 하악의 전방이동량에 따른 불편감은 7.0 mm 이상의 환자에게서 두드러지게 보고되었다. 하악의 전방이동량과 임상 결과와는 직접적인 관련은 없었다. 결 론: 중증도와 상관없이 하악전방이동장치는 폐쇄성 수면무호흡증 환자의 효과적인 치료방법의 하나로 선택될 수 있다. 잠재적인 치과적인 부작용을 방지하기 위하여 하악전방이동장치의 치료시에 하악의 전방이동량을 우선적으로 고려하여야 할 것이다. Objectives: The purposes of this study were to estimate the effect of mandibular advancement device (MAD) and to evaluate the influence of the advancement amount of mandible in the application of MAD for obstructive sleep apnea (OSA) patients. Methods: From the patients who were diagnosed as OSA by polysomnographic study at Seoul National University Bundang Hospital from January 2007 to February 2009, the patients who chose MAD as treatment option were included in this study. All the patients’ data including clinical records and polysomnographic studies (both pre- and post-treatment) were reviewed and analyzed. Results: Successful results were obtained in 65 patients of 86 patients (75.6%). In the follow-up period, mild discomfort of anterior teeth or temporomandibular joint (TMJ) were described in 28 patients, especially in the cases the amount of mandibular advancement were more than 7.0 mm. There was no direct relationship between the amount of mandibular advancement and clinical outcome. Conclusion: MAD was effective treatment option for the OSA patients regardless of severity. For the prevention of potential dental complications, the amount of mandibular advancement should be considered at the time of MAD treatment.

Background: The purpose of this study was to compare the availability of propofol and fentanyl (P + F) with diazepam and morphine (D + M) for intravenous conscious sedation during third molar surgery. Methods: Forty patients without systemic disease were operated under IV conscious sedation administered by either of the two techniques. Monitoring consisted of continuous observation of pulse rate, blood pressure, oxygen saturation, and the respiratory rate and were recorded every 15 minutes. Cooperation score was measured 5 and 15 minutes after induction of IV sedation. Following the operation, the surgeon and patients completed questionnaires including pain visual analog scale, amnesia, and side effects. Results: The P + F group was significantly more cooperative than the D + M group. The side effects of D + M group included pain on injection, nausea/vomiting and abdominal pain. The side effects of P + F group included talkativeness, nausea/vomiting, temporary apnea, pain on injection and vertigo. Conclusions: In this study, there were following benefits in the P + F group; more cooperative status and less pain perception. But respiratory depression developed in some patients.

This study evaluated the use of endoscopy to examine jaw cysts during the operation. Fifteen jaw cysts were explored with a endoscope immediately before and after enucleation. Endoscopic findings were evaluated and recorded with video tape. Before enucleation, there were many white fibrous floating materials within the cystic cavity. Cystic lining showed smooth and regular appearance with capillary network. However, there were some fibrous scar tissues and irregular architecture in preoperative infection. After enucleation, there were white shiny bony surfaces with fresh vascular network. In some cases, floating fibrous tissues remained after removal.

김영균,김현태,이도훈,최윤정,정훈,Kim, Young-Kyun,Kim, Hyoun-Tae,Lee, Do-Hoon,Choi, Yoon-Jung,Chung, Hoon 대한구강악안면외과학회 2001 대한구강악안면외과학회지 Vol.27 No.4

The purpose of this study is to validate the potential etiologic factors for temporomandibular disorder(TMD). TMJ arthroscopic examination was performed in upper joint compartment of 32 joints from 20 patients with mandibular fractures. Synovial fluid was collected from the upper joint space during pumping manipulation with normal saline. Cytologic smearing and histomorphologic exam of synovial fluid were performed in 15 joints. Prostaglandin $E_2(PGE_2)$ concentration was measured in 11 joints. Leukotriene $B_4(LTB_4)$ concentration was measured in 8 joints. There were several arthroscopic variables such as ecchymosis, fibrillation, and adhesion. Histomorphologic exam showed a variety of findings such as bloody smears, cellular cluster, degenerated cells and cartilage, undifferentiated crystal. Mean $PGE_2$ concentrations were 316.5 pg/ml. Mean LTB4 concentrations were 45.9pg/ml. This study demonstrated a variety of findings on inflammatory and degenerative changes of TMJ. Because acute trauma such as mandibular fracture is a major etiologic factor in cartilage degradation and biochemical and intraarticular pathology, clinicians must identify and address TMJ signs and symptoms during follow-up periods in the long term.

The purpose of this study is to evaluate whether the ashed tooth powder is utilized as an alternative material of the implant. For this purpose the author performed the experimental study to investigate the tissue response of sintered toothash and its histocompatibility. Bony defects to expose the body of marrow, $1{\times}1cm$ in size, were created in the right and left mandibular body of mature dog, and then the ashed tooth powders were filled in right side and the blood clot was filled in the left side as an control. The dogs were sacrificed at 4th, 7th, and 16th week after implantation and histologic examination was performed. The results of this study were obtained as follows : 1. Any inflammatory response was not noted after implanting of the ashed tooth powder during the whole experimental period. 2. At 4th week, ashed tooth powders were surrounded by mature connective tissue. And we could observe hydroxyapatite crystal structure within the ashed tooth powder. 3. At 7th week, we could observe that macrophage phagocyted the small granules of ashed tooth powders. 4. At 16th week, the union with host bone by growth of new trabeculae was observed. And there were remnants of ashed tooth power within some of new trabeculae.
