The author used chloride kinin injection to kill three to year old adult male dogs and proceeded to dissect skin tissue and subcutaneous tissue in order to get madibular specimen which was sectioned later, Group one was invested in 50cm depth humid soil, group two was invested in 50cm depth sand, and group three was left immersed In water outside the room. After constant period in water of time had passed, teeth was extracted from each mandibular specimen of each group and were fixed in 10% formalin solution immediately, followed by sectioning the teeth into vertical, sagittal to occlusal, incisal plane to 200um thickness and vertical, parallel line of 1mm2 site to occlusal plane, center of cervical area, dentinal tubule of dentin which is between pulp and enamel was marked in order to measure the synersis and degree of imbibition of dentinal tubule to achieve following conclusions. The results were as follows ; 1. After the extraction, degree of imbibition of adult dog's dentin in soil and sand was rapidly increased in few hours and increased up to 20 hours but later slowly decreased. 2. Maximum imbibition of adult dog's dentin in water was reached in approximately 5 days and the maximum imbibition was reached after more than 20 hours from the investment. 3. The time to reach the maximum imbibition were each different but approximately it was about 3.4∼3.5%. 4. When comparing the gravity curve of teeth to time after death, estimation of morbid time showed that the specimen invested in soil demonstated the most standard tendency curve. When all the conclusions are summerized, it is able to assume the time after death by calulating the degree of imbibition of dentin from different circumstances at the time of death. Using this information, changes after death of hard tissue of human being such as physical, chemical methods and classified researches and experiments on relations to time after death should be done.

Many reports have been published in which bite mark have played a decisive role in identification connected with crime all over the world. Also in Korea, cases involving bite marks have increased considerably since first reports of bite wound 1969. Although all bite mark evidence should be examined only by a highly trained forensic dental expert, there is a very real possibility that bite mark evidence may be initially found or treated by non expert in present Korean postmortem investigation system. For this reason, author have tried to comment here some essential considerations for dealing with bite mark evidence.

醫師의 主意義務의 問題點

The problem of doctor's due care in medical practice is the essential point in judging medical accidents, and is based on the medical intelligence & treatment level and doctor's discretion, all of which, are introduced objectively and ideally from care as good manager point of view. At the same time, modification of Orlaubtos Risoiko according to the legal basis and practical concretization of local facility conditions, specialty, uniqueness, and urgency are carried out before deciding whether the doctor's due care in medical practice is disobeyed. If, his violation is noticed, the possibility of lightening doctor's due care in medical practice according to the present situations of the doctor, disease, as well as medicare, could be considered. Nevertheless, it is demanded that all the medical family members keep the basic ideas of care as good managers in mind, and logically face their work with the will to repay patients for their trust.

A Korean Airliner, KAL 858 was exploded over Thailand on November 29, 1987. The suspect with the forged Japanese passport was dead by biting an ample of cyanide gas contained in the filter tip of a cigarette. Forensic odontological examinations including bite mark, dental age estimation and dental characteristics were performed. From these examinations, it could be assumed that (1) he had specific difference in dental treatment which suggested a North Korean by comparison of the fisherman arrested under the North Korea, (2) the filter of cigarette was positioned between the suspect's dentition, (3) he was approximately 70 years old by dental age estimation at time of death. This paper indicates that forensic odontological examination can support personal identification and the circumstances of death in international case where disguised identity plays a part.

Neuropeptide Y(NPY) was first isolated from porcine brain. This discovery has lead some workers to study the distribution of this peptide in the central nervous system of various mammals. In this study the distribution pattern of neuropeptide Y-immunoreactive neurons was examined in the hippocampal complex of Striped field mouse in Korea(Apodemus agrarius coreae) Experimental animals were anesthesized with thiopental sodium and perfused with 4% paraformaldehyde through the left ventricle and the ascending aorta. The brains were removed and transferred 10%, 20% and 30% sucrose solution. Sections were cut on a cryostat into 40㎛-thick. The tissue was immunostained with free-floating and avidin-biotm complex(ABC) method. The results obtained in this study were summarized as followings. 1. The most of NPY-IR neurons in hippocampus proper were found in the polymorphic layer and a few was found in the pyramidal layer. 2. The process run vertically in the deep polymorphic layer and run parallel to corpus callosum in superficial polymorphic layer. 3. The shapes of neurons in hippocampus proper were varied of polymorphic, oval or round, and the nerve fibers were found in the molecular laver and the hippocampal fissure. 4. The highest density in number of NPY-IR neurons on dentate gyrus were found in hilar area of dentate gyrus. 5. The most of NPY-IR nerve fibers were found in molecular cell layer.

The last stage of plstmortem changes in a carpse is skeletalization. After that stage the skeleton is degraded and actually loses its outline form. This article summarizes the last stages of postmortem stages that is skeletalization and deagadation of the skeleton, and reviews the plstmortem changes of tooth structures which show the final remmants of human body.

법의해부에서 보는 안면부 및 치아 손상

Traumatic injuries to the teeth and the alveolar process are all too frequent childhood and not uncommon adult injury. A traumatically injured tooth is a distressing accident for the patient, and often the final dental restoration leaves much to be desired in appearance as well as in function. Review of a long series of accident cases established that on the basis of frequency the patient's age must be considered a predisposing cause. The greatest incidence appears to be in children from 7 to 11 years of age. At this period in the development of the anterior teeth the crowns are especially vulnerable because of the large pulp chambers. Also at this "toothy age" these teeth frequently crupt in positions of isolated prominence in the arch, and they may be exposed to trauma.
