Forensic odontology in individual identification has been progressing rapidly and its significance has been increasing. But not all individual identification can be done single method solely. Therefore, understanding the advantage and disadvantage of each method is necessary to achieve forensic individual identification properly in each case for it to be applied promptly, economically and precisely. Now We have identified almost 20 case in Busan and Kyeong Nam area in 2008, 2009 and we would like to report some of cases. Finally We will consider role of forensic odontology.

N/A Background : Mohs micrographic surgery (MMS) achieves higher cure rates for cutaneous squamous cell and basal cell carcunomas than any other therapeutic modality. For a unifocal tumor, a 100% cure rate after MMS should theoretically be possible, however for primary basal cell carcinoma, 98-99% 5-year disease-free rates have been achieved. Objective : Our purpose was to investigate the pitfalls in microsscopic Interpretation of frozen sections in Mohs micrographic surgery for basal cell carcinoma which decrease the cure rate after surgery. Methods : From March 1991 to February 1998, fifty-nine patients were diagnosed with basal cell carcinoma at our department. All the tumors were removed with Mohs micrographic surgery and frozen section specimens were stained with hematoxylin-eosin. The microscopic evaluation was done by Mohs surgeon and pathologist. Results : We can summarize the matters that demand special attention during microscopic Interpretation of frozen sections in Mohs surgery as two groups. First, as false negative interpretation, there are 1) small nests of tumor scattered within areas of heavy inflammation 2) tumor present along the hair follicle, 3) tumor present along a cut edge, 4) empty space in a tissue section, 5) hair follicle-like structure of the tumor, 6) gland-like structure of the tumor, and 7) infiltrative BCC-like inflammatory cells. Second, as a false positive interpretation, there are 1) foreign body reactions or scar containing trapped pilosevaceous structures, 2) horizontal and tangential cuts through the pilosevaceous apparatus, 3) some epidermal neoplasms including solar lentigines, seborrheic leratoses, and acantholytic actinic keratoses, and 4) contamination of the tumor tissue. Conclusion : With careful attention to the examples which can affect the interpretation as mentioned above, it may be possible to detect complete removal of tumor mass and achieve higher cure rate. We could achieve a 100% of cure rate for primary basal cell carcinoma and 95% of cure rate for recurrent basal cell carcinoma after Mohs Micrigraphic surgery in our hospital from March 1991 to February 1998.

Fibrin 밀봉제가 흡수성 coral의 골침투, 혈관재생 및 물리적 특성에 미치는 영향

Autogenous bone graft used for the contouring and reconstruction of craniofacial bone defect has many advantages over the alloplastic material implantations. However, there are several problems associated to the autogenous bone grafting: obtaining the donor site is the most problematic; transplanted bone may be absorbed at the recipient site; and the molding to fit to the recipient site is difficult. Therefore, research in alloplastic materials is inevitable. The current research is focused on two types of hydroxyapatite, calcium phosphate and calcium carbonate. The calcium phosphate is known to show a limited osteogenesis. However, Coral(Biocoral, Inoteb B.P., Saint Gonnery, France) composed of calcium carbonate is known to be more effective in osteogenesis. Fibrin sealant(Duplojet system, Immuno AG. Vienna, Austria), a tissue glue, is known to increase tissue affinity, proliferation of fibroblast and vessel ingrowth. It is also known to have osteoinductive effect. We believe that fibrin sealant improves the effect of coral by increasing bone graft substitution, enhancement of plasticity and stability of the granular material. Therefore, we have undertaken an experimental investigation as following; Using high speed burr, three 10 mm in diameter skull defects were made on 24 New Zealand white rabbits. The defects were treated with implantations, which are divided into three samples: A) Control in which on coral or fibrin sealant, B) Coral 50 mg with fibrin sealant 0.3 cc, C) Coral 50 mg with saline 0.3 cc. The specimens of its skull were collected at 3, 7, 14, 28, 42 and 56 days postoperatively. The operative sites were carefully examined grossly, microscopially and radiologically. The experimental results are as followings: At 56 days post operation date, control group showed a thin layer of only fibrous connective tissue and minimal immature bone filling the defect. Coral with saline given group showed a thick layer of connective tissue and granule of coral, accompanied by partial new bone formation, mostly composed of woven bone, in the middle of the defect. In the group that were given coral with fibrin sealant, a thick layer of fibrous connective tissue and granules of coral, accompanied by more increased new bone formation in the middle of the defect were observed. Another difference from the Group B is a formed new bone replaced by lamellar bone. We concluded that by using coral and fibrin sealant together, contouring and reconstruction of bone defected areas were enhanced. It was difficult to prove directly that fibrin has osteoinductive effect. However, the plasticity and stability, the fibrin sealant gives to coral enhances the osteogenesis. Our study provides evidence that coral used with fibrin sealant will significantly improve the result of the craniofacial bone surgery.
