Forensic odontology can be defined in many ways. One of definitions is simply that forensic odontology represents the overlap between the dental and the legal professions. The most important function of forensic odontology to determine of human identity from dental character. We had found 7 unidentified human bodies in Busan metro politan city, 2007 and we have identified 5 bodies among them.

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 4 cases of forensic odontology are studied. 2 cases are age identification and 2 cases is forensic confirmation.

This paper is a study of the functions required for the system to quantify the closest target weight by combining several random weights such as chips, snacks, fruits, and vegetables. The multi-head weigher is designed for high-performance applications requiring increased production rates and tight accuracy tolerances. This combination system has 12 heads considered in the form of a rectangular array of 2X6 or 3X4. Channel combination can usually occur between 1 and n, and the frequency was the highest with two or three combinations. Experimental result of a combination system for a total target weight was measured at the range from 100g to 500g by increments of 50g, and the average success rate was about 70%. The average elapsed time was about 1.7 seconds, which means it can be used for the packaging of agricultural products with a variety of items.

Polymyositis is one form of inflammatory myopathy. In some patients, this disease does not entirely respond to conventional initial therapy with glucocorticoid, methotrexate and azathioprine. Multiple options exist for treating these patients, but only intravenous immune globulin has been subjected to a randomized clinical trial. We report here on a case of polymyositis that did not respond to multiple drug therapy, but it did respond to tacrolimus. After treatment with tacrolimus, the patient`s disease has been well controlled for many years.

The study was intended to investigate how dentists in private dental clinic thought on the present claim and review of dental insurance to reflect it in future establishing dental insurance policies. 1,465 dentists who were running own dental clinic in Pusan Metropolitan City and the south part of Kyungsang province were surveyed in February, 2004. A total of 406 copies of finished questionnaire were finally retrieved and analyzed. The findings are as follows. 1. About insurance claim affairs : Most of the subject of insurance claim was by dentist himself or dental hygienist(nurse). Agency claiming was carried under 20% of total insurance claim. 2. The degree of attendance on insurance lecture : The degree of attendance on insurance lecture was relatively low. 3. Filing a protest against insurance claim : Filing a protest against insurance claim was reavealed about half-and-half for "have been" or "have not been". 4. Private clinic dentist,s opinion about the regulations affecting review of dental insurance : Private clinic dentists opinion about current guide for insurance review of dental fee was“the guidance is difficult and unfair cutback of claim fee may be carried”. 5. The affairs about health insurance review agency : About 70% of private clinic dentists have dissatisfaction on health insurance review agency. 6. Standpoint of private clinic dentists about issuance of receipt for dental fee : About 70% of private clinic dentist have an difficulty in issuance of receipt for dental fee. 7. The affairs about change insurance noncoverage treatment to insurance coverage treatment : Most of private clinic dentists hoped that insurance coverage about full mouth scaling, pit and fissure sealant, fluoride application. But they do not hoped that insurance coverage about geriatric denture, prothodontic treatment except precious metal, photopolymerization resin treatment.

The aim of this study was to evaluate bone scan(SUR) and SPECT(hot spot) in patients with TMJ osteoarthritis. 99mTc-MDP bone scan and SPECT were done in 27 patients, total 54 temporomandibular joints were examined with clinical examination, plain radiography. 42 TMJs were osteoarthritis and 12 TMJs were normal case, clinically diagnosed. We compared osteoarthritis group and control group of bone scan(SUR) and SPECT(hot spot). thus we compared before and after treatment of bone scan(SUR) and bone SPECT(hot spot) according to history, contributing factor, symptom degree, treatment, treatment period. The obtained results were as follows. 1. Bone scan(SUR) and SPECT(hot spot) activity of osteoarthritis group were higher than control group(P<0.05, P<0.01). 2. Bone scan(SUR) and SPECT(hot spot) activity were decreased after treatment at TMJ with osteoarthritis(P<0.01). 3. Bone scan(SUR) and SPECT(hot spot) activity were decreased at treatment group with splint(P<0.01, P<0.05). 4. Bone scan(SUR) and SPECT(hot spot) activity were decreased at Chronic group(P<0.01, P<0.05). 5. Bone scan(SUR) and SPECT(hot spot) activity were decreased at low noise NAS(<6) group(P<0.01,P<0.05). 6. Bone scan(SUR) and SPECT(hot spot) activity were decreased at TMD patient with parafunctional habit and without trauma history, psychosocial factor. 7. Bone scan(SUR) and SPECT(hot spot) activity were higher at before treatment required more treatment period.

The purpose of this study was to investigate whether there were any changes in taste sensitivity with recurrent aphthous ulceration. Nintyseven subjects(25 males and 72 females) were included for the study and they were categorized into 2 groups(recurrent aphthous ulceration 27 persons, control 70 persons), recurrent aphthous ulceration group was investigated in the department of Oral Medicine, College of Dentistry, Pusan National University from April, 2005 to August, 2006 and control group was investigated in the clinic at Incheon city from June, 2006 to August, 2006. The electrical taste thresholds were measured using an electrogustometer of the 4 different sites(tongue tip, tongue lateral, circumvallate papilla and soft palate) in oral cavity. The results were as follows ; 1. The electrical taste threshold showed significant lower in the RAU group. 2. The electrical taste threshold showed significant lower in female group, and showed significant lower except soft palate in male group of the RAU group. 3. The electrical taste threshold showed a tendency to increase in all site of the multiple RAU group, but there were no significant differences. 4. The electrical taste threshold showed a tendency to increase in tongue lateral of the acute RAU group, and showed a tendency to increase in tongue tip, circumvallate papilla, soft palate of the chronic RAU group. 5. After treatment, electrical taste threshold was significant increase than initial visit in the RAU group. 6. After treatment, NAS showed a tendency to decrease in the RAU group.

Temporomandibular joint arthritides is divided into osteoarthritis, osteoarthrosis and polyarthritis. Because the signs, symptoms and radiographical features of osteoarthritis and osteoarthrosis are similar without arthralgia, diffenential diagnosis is difficult. Also non-radiographically change in early Osteoarthritis leads to misdiagnose. Planar bone scan and SPECT are useful to detect bone change early. This study was carried out in order to make diagnostic criteria of planar bone scan and SPECT. Three hundred and four temporomandibular joints were examined with clinical examination, computerized tomograph, planar bone scan, and SPECT. The obtained results were as follows. 1. If temporomandibular joint simple uptake ratio of patient in twenties is over 1.397%, it's condition may be osteoarthritis. And simple uptake ratio over in thirties-fourties may mean osteoarthritis. 2. It may mean osteoarthritis of temporomandibular joint that the number of coronal and transverse SPECT frame with hot spot is over four. 3. Destructive stage may goes on, if simple uptake ratio is over 1.370% in tweenties and over 1.104% in thirties-fourties. 4. If the number of coronal SPECT frame with hot spot is over four, temporomandibular joint may be on destructive stage in tweenties, thirties-fourties. And if the number of transverse SPECT frame with hot spot is over three, it may be on destructive stage in all ages. 5. When patient complains subjective arthralgia and palpation arthralgia, bone change may be more active than each arthralgia. 6. Osteoarthritis may progress gradually worse in 4.5 anamnesis. And then it may be stable gradually and turn to osteoarthrosis.

The life changes of TMJ patients were evaluated through the Social Readjustment Rating Scale (SRRS) questionnaire. 33 recurred TMD patients and 32 new TMD patients were studied at the TMJ clinics, Department of Oral Medicine, PNUH from September 2005 to August 2006. The obtained results were as follows: 1. The life change unit(LCU) totals in the recurred TMD patients were significantly higher than those in the control subjects, during the $7{\sim}12$ months before presentation for the hospital. 2. The life change unit(LCU) totals in the recurred TMD patients were higher a little than those in the control subjects during a year before presentation for the hospital. 3. There was no significant difference in LCU totals and life events between the recurred TMD patients and the control subjects by age. 4. There was no significant difference in LCU totals and life events between the married group and unmarried group in the subjects.
