Purpose: To evaluate the effect of silvernanopartilce treated implants on the bone formation and osseointegration. Methods: Silvernanoparticle was produced using an anodic oxidation method. The size of silvernanoparticle ranged from 3.5 nm to 5.9 nm. To check the effect of the capability of osseointegration of silvernanoparticle coated Implant, 32 implants (16 piece of Implant treated with nanoparticle, and 16 piece of Implant was not treated for control) were placed at both the tibia of 8 New Zealand white rabbits. After 4 weeks, 4 rabbits were sacrificed and the removal torque was measured for comparison of the osseointagration ability. Further, 4 rabbits were sacrificed and sliced samples were made. H&E stain was done for microscopic finding. Results: The removal torque of the experimental group was
N/cm, and the control group was
N/cm. It was statistically significant (P<0.001). Microscopic finding also shows extinguish results in silvernanoparticle treated implants. Bone formation rate of the experimental group was 43.94% and the control group was 7.58%. It was observed to be statistically significant (P=0.017). Bone to implant contact rate of the experimental group was 58.09%, and the control group was 19.43%. It was found with statistical significance (P<0.001). Conclusion: The silvernanopartilce treated implant shows a better capability of bone regeneration and osseointegration than the non-treated one. Technology to produce smaller particles would make silver more useful and safer.

Purpose: Vascular endothelial growth factor (VEGF) plays a key role in tumor angiogenesis and lymphangiogenesis including induction of endothelial cell proliferation, migration and capillary tube formation. E7080 (S1164, Selleck chemical, Houston, TX, USA) is a muti-targeted kinase inhibitor, which targets VEGF receptor-2, 3 (VEGFR-2, 3) and inhibits survival and proliferation of tumor cell. The purpose of this study was to determine the anti-tumor effect of E7080 on oral squamous cell carcinoma. Methods: An oral squamous cell carcinoma cell line, SCC-9 was used in this study. E7080 was applied to SCC-9 cells by 3 different concentrations (1, 5, 10
). Control means no application of E7080. The cellular growth was evaluated by real-time cell electronic sensing and MTT assay. The signal transduction was evaluated by Western blotting. Results: In experimental group, SCC-9 cell proliferation was decreased and the VEGFR-3 downstream pathways were inhibited compared with control. Furthermore, increasing the concentration of E7080, the ability of E7080 to disturbance of SCC-9 cell proliferation was increased. Conclusion: Proliferation of SCC-9 cells was inhibited by E7080, which was through by inhibition of VEGFR-3 downstream pathway. In vivo study with E7080 will be required to provide therapeutic benefits in oral squamous cell carcinoma.

Purpose: The purpose of the study is to evaluate the effectiveness of anterior segmental osteotomy (ASO) in bimaxillary protrusion (BP) patients by comparison between the mandibular soft and hard tissue changes from orthodontic treatment and ASO. Methods: All 44 patients were diagnosed with BP in Kyung-Hee Medical Center. Orthodontic treatment with teeth extractions were underwent by 23 patients (Group A) and 21 patients underwent ASO (Group B). Mandibular soft and hard tissue changes were measured and evaluated, which were based on the vertical and horizontal reference line in lateral cephalometric radiographs. Statistical significance between the changes and correlation between each measurement were analyzed. Results: The amount of B point movement was lesser than that of the lower incisal tip (LIT) retraction, and LIT was tilted lingually in group A. The posterior movement discrepancy between LIT and B point was insignificant, and the inclination of lower incisor was not changed in group B. The soft tissues, including the lower lip, showed a posterior movement and reduction in the depth of mento-labial groove. According to the correlation analysis, the movement of the lower incisor was significantly related to the movement of the lower lip in group A, and the movement of the lower incisor was significantly related to that of the movement of lower lip, B point and Pog in group B. Conclusion: The orthodontic treatment in BP patients results in posterior tilting movement of the lower incisor, but ASO results in the bodily movement of the lower incisor. Consequently, ASO is more effective in BP cases because it ensures the controlled movement of the lower incisors.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 4, 2012, Pages 252~259
Purpose: This study evaluated the postoperative stability of counter clockwise rotation of the mandibular plane in anterior openbite patients, who have had one jaw surgery performed. Methods: This study includes patients with skeletal class III malocclusion accompanied by anterior openbite among the patients who have had BSSRO performed, resulting in counter clockwise rotation of the mandibule. We excluded the patients with genioplasty and segmental surgery, and included 23 patients who underwent BSSRO. Results: We found no statistical significance between the amount of counter clockwise rotation in the mandible in the Pearson correlation test. Also, there was no significant difference between Group 1 (<
) and Group 2 (>
). Conclusion: This study evaluated the amount of horizontal relapse, and the degree of relapse. Stable results were obtained. Although there was no statistical significance between the degree of openbite and the amount of horizontal relapse, the group with a greater amount of openbite had a greater amount of relapse.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 4, 2012, Pages 260~266
Purpose: The purpose of this study is to identify the changes of a physiologic nature and the sedative parameters associated with dexmedetomidine and pethidine, in patients undergoing plate and screw removal surgery, after orthognathic surgery. Methods: Twenty-three patients were sedated with dexmedetomidine and pethidine during plate and screw removal, after orthognathic surgery. An initial loading dose of dexmedetomidine (
infused over 10 minutes) was followed by a maintenance dose (
). Systolic blood pressure, diastolic blood pressure, mean arterial pressure, oxygen saturation, and heart rate were monitored. Perioperative amnesia and anxiety were recorded. Results: Significant changes were found in the blood pressure and heart rate (Freidman test, P<0.05), but not in oxygen saturation (Freidman test, P>0.05). Amnesia during local injection was observed in eight patients (34.8%). Compared with the preoperative anxiety score, the intraoperative anxiety score was decreased. Conclusion: In this study, we found cardiovascular and respiratory stability in intravenous sedation using dexmedetomidine with pethidine, in plate and screw removal, after orthognathic surgery. Furthemore, intravenous sedation using dexmedetomidine with pethidine shows adequate analgesic and sedative effects.

Lipoma is the most common benign neoplasm of the body with rare occurrence in the oral cavity. It represents 1~4% of benign neoplasms of the mouth, which affect the buccal mucosa, floor of the mouth, tongue and lips. We report a case of lipoma in the labial vestibule with extraoral swelling, which could easily be misdiagnosed as an odontogenic abscess. Excisional biopsy in this case revealed well-circumscribed masses, surrounded by a thin fibrous capsule and composed of sheets of mature adipocytes, arranged in a "chicken wire" configuration. After a computed tomography scan, excisoinal biopsy was done, and there were no recurrence after 5-month follow-up period.

Squamous cell papillomas are one of the most common lesions of the oral mucosa with a mucosa of the hard and soft palate, including the uvula, palate, tongue and lips. As an oral lesion, it raises concerns because of its clinical appearance, which may mimic exophytic carcinoma. Its pathogenesis is related to the human papilloma virus (HPV), but there is controversy regarding its viral origin. Many considered its pathogenesis as being from the HPV. But recent literature suggests that the presence of HPV may be merely an incidental finding unrelated to the development of a squamous papilloma. We accidentally found a patient not related to the HPV of oral squamous papilloma on the tongue, and we will report this case with literature review.

The development of multiple primary tumors is a problem leading to the treatment of patients diagnosed with gingival squamous cell carcinoma (SCC). The occurrence of multiple primary cancers in patients with SCC of the head and neck is uncommon. Thyroid carcinomas have been found incidentally in the cervical lymph nodes after histopathologic examination. A 72-year-old male with SCC of the lower gingiva at the clinical stage T2N0M0 was treated with partial mandibulectomy and selective neck dissection. Histopathologic examination showed the foci of papillary thyroid carcinoma metastasis. The patient subsequently underwent total thyroidectomy. We report a case of papillary thyroid carcinoma associated with SCC of the oral gingiva along with a review of literatures.

From the standpoint of general guidelines of a dentist, the following conditions should be considered before replanting a permanent tooth. The avulsed tooth should be without advanced periodontal disease. The alveolar socket should be reasonably intact in order to provide a seat for the avulsed tooth. The extra-alveolar period should be considered, i.e. periods exceeding. 2 hours are usually associated with marked root resorption. But, the above mentioned regulations are often difficult to keep in the actual situation of the medical emergency room, owing it to the delay of primary medical care in multiple trauma patients. The successful cases have been reported with minimal root resorption in the long-term periods, in spite of extra-alveolar periods of several hours and combined alveolar bone fracture. This is a case report regarding the effect of endodontic drainage in delayed replantation after a prolonged extra-alveolar period of the avulsed teeth with alveolar bone fracture.

The lateral upper arm flap (LUAF) was initially described by in 1982 by Song et al. as a simple skin flap, addressing the availability of cutaneous nerves for anastomoses. Katsaros et al., reported the use of a lateral upper arm skin flap, but also considered using it as a composite graft. The LUAF for the oral and maxillofacial reconstruction has several advantages over other flaps, such as constant anatomy, good color match and texture, thin design and plasticity. There is no functional limitation in the donor arm, such as strength and extension, and donor defects can be closed primarily with a linear scar, even when a flap of up to 8 cm in width is taken. For a better understanding of LUAF as a routine reconstructive option in moderate defect of maxillofacial region, the constant anatomical findings must be learned and memorized by young doctors during the specialized training course for the Korean national board of oral and maxillofacial surgery. This article review the anatomical basis of LUAF with Korean language.
