150 "K" primary school children, from 6 to 10 years old, have been examined both clinically and radiographically for proximal caries in deciduous canine and deciduous posterior teeth and permanent first molar teeth. 1. 598 proximal cavities were diagnosed 154 (25.75%) were revealed by both examinations. 39 (6.52%) appeared on clinical examination only, but 405 (67.73%) were revealed by radiographic examination only. 2. The dental caries occurance on distal surface of first deciduous molar and mesial surface of second deciduous molar were revealed much higher values in all ages. 3. There is no significant differences observed between right and left arch. 4. Proximal cavities were revealed 1.7 times more in mandible than in maxilla.

The National Health Insurance Act, the Industrial Health Act and the School Health Act require chest radiography at least once a year. In chest radiographic examination, most group examinations use indirect X-ray primarily aiming at diagnosing diseases and enhancing people's health. This study purposed to minimize radiation exposure dose by comparing it between direct and indirect chest X-ray studies. According to the result of comparing and analyzing radiation exposure dose, the average incident dose and penetrating dose were 0.929μGy and 0.179μGy respectively in direct chest X-ray and 6.807μGy and 1.337μGy in indirect chest X-ray In order to minimize radiation exposure dose at direct and indirect chest X-ray, indirect X-ray should be excluded from group examination if possible. Moreover, it is necessary to control the quality of equipment (Q/A & Q/C) systematically and to avoid using unqualified equipment in order to reduce radiation exposure dose.

A 15-year-old intact female poodle dog was referred to a local animal clinic showing signs of dyspnea. A radiographic examination revealed multiple nodules in the lung. The following day, the animal died and a necropsy examination revealed multiple nodular masses of varying sizes in the lung. Microscopically, the tumor cells were composed of round to polygonal cells resembling adipocytes with little or no collagenous stroma. Most of the cells contained clear cytoplasmic vacuoles with the nucleus at the periphery while the other cells contained varying numbers of smaller vacuoles. The immunohisto-chemical evaluation yielded a positive reaction to S-100 and vimentin. Negative results were obtained for pancytokeratin, smooth muscle actin, desmin, epithelial membrane antigen and CD68. This case was diagnosed as a well-differentiated liposarcoma.

Arteriovenous malformations are extremely rare conditions in that can result from abnormalities in the structure of blood vessels, which may be potentially fatal. A 30-year-old female patient visited our hospital with a complaint of swelling on the right maxillary posterior gingiva along with the large port-wine stain on right side of face. On clinical examination, the swelling was compressible and pulsatile. Radiographic examination revealed a lytic lesion of maxilla. Diagnostic angiography revealed a high-flow arteriovenous malformation of maxilla which was treated by selective transarterial embolization of maxillary artery using polyvinyl alcohol particles.

Subungal exostosis is a rare benign cartilaginous tumor affecting the distal phalanx. From 1995 to 1996, six subungal exostoses of the hallux were treated in the Chonnam national university hospital. The symptoms were subungal pain, mass on the distal phalanx elevating the nail or causing ulceration of the nail bed. The plain radiological examination showed a bony mass occurring on the dorsomedial or medial aspect of the distal phalanx. The diagnosis of the subungal exostosis of the hallux were suspected from clinical presentation and confirmed with radiographic examination. Histological patterns were fibrocartilaginous cap with the mature trabecular bone. Complete excision of the lesion including overlying nail bed was curative without recurrence in all cases.

A revascularization procedure was shown to be the best alternative therapy for immature teeth with necrotic pulp and apical infection. A 12 year old female with a history of trauma to her upper central incisor and a sinus tract was referred for endodontic treatment. She was an active orthodontic patient and had undergone regenerative endodontic treatment for the past 2 years. Clinical examination revealed no response to sensibility, percussion, and palpation tests. The preoperative radiograph showed an open apex and apical rarefaction. The case was diagnosed as previously treated tooth with asymptomatic apical periodontitis. Regenerative endodontic retreatment was performed, and the case was followed for 3 years. Clinical, radiographic, and cone-beam computed tomography follow-up examination revealed an asymptomatic tooth, with evidence of periapical healing and root maturation.

Male pseudohermaphrodites is one of abnormalities of phenotypic sex and have an XY chromosome constitution and testes, but the internal or external genitalia are to some degree those of a female. We surveyed one case which were referred in Veterinary Medical Teaching Hospital of Seoul National University. When patient was purchased, its phenotype was entirely female that have female external genitalia. However, from the age of 6 months, clitoris was gradually increased to Os clitoris, and patients showed male behavior. Critical clinical sign was trauma of protruded Os clitoris. In radiographic and ultrasonographic examination, he had normal vagina and urinary bladder. In chromosome examination, he had an XY chromosome constitution. This case was performed removal of Os clitoris and ovariohysterectomy.

An intact female, 2 month old, domestic short hair cat, weighing 0.82kg with a history of respiratory distress, anorexia, and depression for 3 days was referred. In laboratory examination, there were no remarkable abnormalities. Radiographic findings mainly included pleural effusion, dilation of pulmonary vessels, pulmonary edema, and ascites. Echocardiography showed dilation of four cardiac chambers, malformation of the tricuspid and mitral valve, and atrioventricular valve regurgitant jet flow. The cat was euthanized by client's request and confirmed to the tricuspid and mitral valve dysplasia by necropsy and histopathologic examination.

A castrated, 6-year-old, male Turkish Angora cat with a history of respiratory distress was referred to the hospital. Physical examination revealed a cardiac murmur, and thoracic radiographic findings revealed pleural effusion and cardiomegaly. Echocardiography showed abnormality of the tricuspid and mitral valve, and color-flow Doppler imaging revealed regurgitation between both atrium and ventricle. Based on the echocardiographic examination, tricuspid valve dysplasia concurrent with mitral valve dysplasia was diagnosed. However, the patient died a week after treatment. In necropsy, bilateral atrioventricular valve dysplasia and left ventricular hypertrophy were confirmed. This is the first report to describe a middle age Turkish angora cat having bilateral atrioventricular valve dysplasia which has high mortality and only been reported rarely in cats. This case report also describes its clinical signs, diagnostic imaging findings, treatment and discussions how the patient could live long.

A 3-year-old, captive female river cooter was presented with a 4-day history of progressive unilateral swelling of the right side of the head, lethargy, and anorexia. History, physical examination, and radiographic examination revealed an aural abscess. After administration of antibiotics and supportive care, surgical intervention was performed. Swab samples were collected from the tympanic cavity during surgery for cytology and antimicrobial susceptibility testing. Molecular analyses of 16S ribosomal RNA gene sequences identified Citrobacter spp. and Morganella morganii. The patient was treated with ciprofloxacin and meloxicam and recovered after 2 months. This report describes the successful correction of a unilateral aural abscess that responded well to surgical intervention and a properly selected antibiotic.
