Purpose : This research evaluates the effect of the use of absorbable membrane barrier with deproteinized bovine bone (Bio-
, Switzerland) on bone healing in surgically created critical-sized defects in rat calvaria. Materials and Methods : Two standardized transosseous circular calvarial defects (5 mm in diameter) are made in each calvarium of 30 rats. These rats are divided into negative control group(n=15), positive control group(n=15) and two experimental groups(n=15). In the negative control group, defects are only filled with blood clots. In the positive control group, defects are filled with autogenous bone obtained from calvarium; in the experimental group 1, defects are filled with deproteinized bovine bone; and in the experimental group 2, defects are filled with deproteinized bovine bone with absorbable membrane. At the postoperative 1 week, 3 weeks. and 6 weeks, clinical. histologic and histomorphometric evaluations of the defects are performed. Results : 1. The grafted bone without membrane in the calvarial bone defect was scattered but, the grafted bone with membrane was stable. 2.
membrane was absorbed beginning at 3 weeks, and was absorbed considerably at 6 weeks while maintaining the structural form of the membrane. 3. The use of membrane blocked soft tissue invasion. 4. In histomorphometric analysis. it showed the greatest amount of new bone formation in the positive control group. The amount of new bone formation was greater in the experimental group 2 than experimental group 1. At 6 weeks. the amount of new bone formation was greater in the positive control group than experimental group l(p<0.005). Conclusion : These results suggest that membrane increase the stability of grafted bone and protects from soft tissue invasion, and the use of the membrane may promote new bone formation in deproteinized bovine bone graft area.

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.

Objective : The objective of this study was to compare the surgical techniques for the correction of congenital cleft palate. Techniques and approaches : Four-hundred-sixity patients operated between 1993 and 2008 were included in this study. The collected data were age, sex, operating time, admission days, and complications. The comparison between techniques were done by independent t-test. Results: The majority (86.9 %) of patients were received the operation later than 1.5 years old. The distribution of each surgical technique was 43.8 % by Bardach palatoplasty, 11.9 % by Furlow palatoplasty, 1.8 % by Veau palatoplasty, and 42.4 % by the new technique developed by us. Postoperative complication such as wound dehiscence, formation of oro-nasal fistulas in the soft and hard palates were shown in 23.0 % of Bardach technique, 44.2 % of Furlow technique, and 37.5 % of Veau technique. However, only 5.4 % of patients were shown complications in our technique (P<0.001). The operation time was recorded 70 minutes under new technique while the others were 110 minutes (P<0.001). The clinical treatment at hospital was required 7.4 days for our technique and 11.3-15.5 days for the other methods. Conclusion : The surgical treatment of congenital cleft palate in Mongolia was conducted later than proper timing for surgery. As the results were indicated, our new technique should be considered for the correction of cleft palate in old aged patients.

Objectives: This study was performed to evaluate course of the inferior alveolar canal in the mandibular ramus and to find safety zone when ramal bone is harvested. Patients and Methods: From January, 2009 to February, 2009, the 20 patients who visited in the Department of Oral and Maxillofacial Surgery, Sanbon Dental Hospital. Wonkwang University and the Conebeam CT was taken of various chief complaints, were selected. The patients who had left and right mandibular first molar and incisor missing, jaw fracture and bone pathology were excluded. The R point was defined as the point which occlusal plane was crossed to the mandibular anterior ramus(external oblique ridge). In the cross-sectional coronal and axial views, the inferior alveolar canal position to the R point, buccal bone width(BW), alveolar crest distance(ACD), distance from alveolar crest to occlusal plane(COD) and inferior alveolar canal to sagittal plane(CS) were measured and horizontal distance(HD), vertical distance(VD) and nearest distance(ND) were measured. Results: The inferior alveolar canal is located
from the R point. Horizontal distance from the R point were
, vertical distance from the R point were
and nearest distance from the R point were
. The course of the inferior alveolar canal was positioned within
. The distance from external buccal bone to the inferior alveolar canal was increased from the R point anteriorly. Conclusions: It is considered that the mandibular ramus from the R point to 10 mm anteriorly can be harvested safely at ramal bone grafting.

Purpose : On outpatient facilities, our sedation protocol focuses on the intermittent bolus injections of midazolam intravenously, according to patient's and operator's needs during the dental treatment. This multicenter retrospective study was aimed to prove the efficiency and safety of our sedation protocol. Patients and Methods : In three centers using the same outpatient sedation protocol for dental treatment (Division of Oral and Maxillofacial Surgery/Department of Dentistry in Hanyang University Medical Center, S-plant Dental Hospital. and Grand Oral and Maxillofacial Surgery), total 937 patients had various dental treatments under intravenous conscious sedations with independent patient monitoring from March 2006 to March 2009. By reviewing charts, we analyzed the results of sedation and dental treatment, retrospectively. Results : Our sedation protocol had no severe postoperative complications requiring admission. while showing good compatibility with almost all dental treatments, with acceptable satisfaction of both patients and operators. Conclusion : We assure that our sedation protocol can be used efficiently and safely on routine outpatient basis. We also hope that this study will provide the concrete concepts to common dental practitioners, who desire to perform sedation for dental treatment.

Purpose : This study was designed to evaluate the clinical aspect of cysts which arised in the oral and maxillofacial region. Patients and Methods : We reviewed clinical record, radiograph, histopathologic and operative report of 155 patients who had been diagnosed as cysts and treated at the department of oral and maxillofacial surgery in Chonnam National University Hospital from January 2003 to December 2008. Gender, age, classifiaction, anatomic distribution, clinical sign and symptoms, treatment, complications and recurrence rate were studied. Results : 1. Among 155 patients, the male patients(64.5%) were more than the female(35.5%). 2. The average age ofthe patients was 37.2 years(ranging from 5 to 79 years). 3. In pathologic classification, radicular cyst and dentigerous cyst were most common cysts, irrespective of 73 cases(48.3%) and 35 cases(23.2%). 4. The frequently involved cystic regions were followed as mandibular molars(38.1%), and maxillary incisors(30.2%). 5. The frequent sequence of clinical symptoms was edema(29.9%), no symptom(18.9%), tenderness(13.9%), pain(11.5%) and abscess(9.4%). 6. The most prevalent treatment was the combination operation, such as cyst enucleation with extraction or endodontic treatment of the causative tooth(76.8%) 7. Among 155 cases, 2 cases that were treated using enucleation method were recurred(1.3%).

Odontogenic keratocyst (OKC) is a epithelial developmental cyst which were first described by Phillipsen in 1956. The frequency of OKC has been reported to vary from 3% to 11% of odontogenic cysts. The most characteristic clinical aspect of OKC is the high frequency of recurrence. The mechanism of recurrence is thought to be related to residues of cyst epithelium and an intrinsic growth potential following excision. And since the lining of the OKC is thin and friable, removal of the cyst in one piece may sometimes be difficult. Complete removal of the cyst lining without leaving behind remnants attached to the soft tissue or bone is necessary to avoid recurrence. Therapeutic approaches vary in different studies from marsupialization and enucleation, which may be combined with adjuvant therapy such as cryotherapy or Carnoy's solution, to marginal or radical resection. The recurrent rate varies from approximately 20% to 62%. And OKC in the angle-ramus region of the mandible had a higher tendency to recur, because of the difficulty in accessing and removing OKC from the ramus. By employing a sagittal splitting of the mandible a good surgical access was provided and cyst could be removed completely. We present an illustrative case of a small, lobulated OKC that involved ramus on mandible, and a review of the contemporary literature.

Pemphigus vulgaris is a chronic autoimmune intraepithelial blistering disease with oral mucosal manifestations that very often precede the skin lesions. The vesicles or bullae are produced by an acantholytic process, detachment of differentiating keratinocytes from one another in the epithelial stratum spino sum or spinous cell layer. The pathogenesis of this disease is initially manifested by IgG(mainly) binding to desmosome(desmoglein 3 or 1) in the intercellular spaces of epithelium. This autoantibody binding caused the release of a plasminogen activator(a proteolytic enzyme) from keratinocytes. This ultimately results in cell to cell separation. The mainstay therapy of pemphigus vulgaris is systemic corticosteroids and immunosuppressive agents to eliminate the pathogenic autoantibodies from circulation. A 41-year old woman presented with a 1.5 year history of oral ulceration. There were no lesions on the skin or other mucosal sites. Histology and immunostaining were consistent with pemphigus vulgaris. Control of oral ulceration and normal oral function were achieved after systemic corticosteroids and immunosuppressive agents were instituted.

Odontogenic myxoma, a rare tumour that occurs in the jaws, locally invasive, destructive tumors that do not metastasize to lymph nodes. Large odontogenic myxoma on mandible is treated by mandibulectomy, defected mandible is reconstructed by bone graft. Reconstructed mandible is difficult to reconstruct dentition using implant because of deficiency of bone amount. So it is necessary to additional bone graft. But a poor aspect of soft tissue lead to unsatisfactory result. Because of distraction osteogenesis is possible to reconstruction of an amount of bone and soft tissue, that is advantage to reconstruction of alveolar bone on reconstructed mandible. We report with review of literatures the 25 years old male patient who had odontogenic myxoma in left mandible, was undergone mandibulectomy and successfully implant installation and prosthetic restoration after distraction osteogenesis(Track
, KLS Martin, Germany) on the reconstructed mandible with a free iliac bone graft, and we have conservative and successful result.

Basal cell nevus syndrome is a rare inherited disorder characterized by mulitple cutaneous basal cell carcinoma, pits of the palms and soles, cysts of the jaws, skeletal abnormalities and ectopic calcifications. Currently there are new lines of investigation based on biomolecular studies, which aim at identifying the molecules responsible for these cysts and thus early allowing an early diagnosis of these patients. We report a case of a 9-year-old boy with the various manifestation of basal cell nevus syndrome, which are multiple odontogenic keratocysts, pits of the soles, bifid ribs, ectopic calcification, macrocephaly, and hypertelorism, etc. Total five odontogenic keratocysts were found. For the reduction of the size of the odon-togenic keratocysts, following preoperative marsupialization, there were surgically enucleated. And the impacted upper right lateral incisor and canine are tracted orthodontically.

The peripheral ossifying fibroma(POF) is a relatively common, non-neoplastic gingival growth that is classified as a reactive hyperplastic inflammatory lesion. The clinical appearance of POF is generally a small, well-circumscribed, focal mass with a sessile or pedunculated base. The pathogenesis of this lesion is uncertain. POFs are believed to arise from cells of the periodontal ligament as hyperplastic growth of tissue that is unique to the gingival mucosa. Approximately 60% of POFs occur in the maxilla, and 55%-60% of all cases occur in the incisor-canine area. Most lesions are less than 2 cm in size. To our knowledge, huge POF of approximately 8 cm in size in the lower posterior edentulous ridge has not been previously described in the English literature. We report an unusually huge POF overlying the lower posterior edentulous ridge mucosa, along with long-term follow up result.

Cleidocranial dysplasia(CCD) is a rare syndrome usually caused by an autosomal dominant gene or no apparent genetic cause. The skull is large and short with marked bossing of the frontal bone. Closure on the fontanelles and sutures is delayed. The clavicle may be unilaterally or bilaterally aplastic. Oral manifestations include multiple impacted permanent teeth, prolonged retention of primary teeth and multiple supernumerary teeth. There are many difficulties in the early diagnosis of CCD because a majority of the craniofacial abnormalities becomes obvious only during adolescence. Late diagnosis produce occlusional & psychological problem. Therefore early detection and treatment of CCD can reduce the period and the extent of orthodontic and surgical interventions. We experienced CCD patient with multiple supernumerary teeth and will report it with the literature review.
