치아 수복 후 나타날 수 있는 술 후 동통과 치수 병변의 주원인은 수복재 자체의 독성보다는 박테리아의 침투에 의한 것으로 알려져 있으며, 와동내 항균제 처리는 잔존 박테리아를 제거하여 제 증상을 완화하는데 효과적이지만, 상아질면이나 상아세관에 잔유물을 남겨 상아질 결합제와 치질간의 긴밀한 결합을 방해하여, 미세누출을 증가시키고, 결합강도를 약화시킬 수 있다고 알려져 있다. 2% 클로르헥시딘 도포가 접착성 수복물과 치질과의 결합강도 및 미세누출에 미치는 영향을 평가하기 위하여, 건전한 소의 전치 상아질을 노출시키고 와동을 형성한 후, 클로르헥시딘을 도포하고 복합레진, 컴포머 그리고 글라스아이오노머를 각 제조사의 지시에 따라 각각 충전하고, 100회 열순환 처리 후 전단 결합 강도와 미세누출 양상을 비교 평가하였다. 상아질 전단 결합 강도와 수복재 변연 미세누출 양상에서 실험군과 대조군간에 통계학적 유의차를 보이지 않았다. Bacterialmicroleakage around restorations is considered the principal cause of pulpal inflammation associated with restorations. The rationale for using cavity disinefectant is based on its antimicrobial properties but the cavity disinfectant may leave debris on dentin surfaces. The purpose of this study was to evaluate the effect of 2% chlorhexidine on shear bond strength and microleakage of adhesive restoration. 45 sound bovine teeth were used for the shear bond strength test and 30 for the micorleakage. For the experimental groups, 2% chlorhexidine was applied before the restorations, and was not for the control groups. The result from the this study can be summarized as follows; 1. No significant difference could be found in shear bond strength of each group. 2. No significant difference could be found in microleakage of each group.

The purpose of this study was to evaluate the detectability of various radiographic techniques for mandibular condylar lesions. Erowive lesion, osteophyte and flattening were formed on the artificial mandibular condyle, and panoramic, transcranial, transorbital radiography, lateral and frontal tomography were taken. The results were as follows; 1. The detectability for erosive lesions was superior in the order of frontal tomography(96%), lateral tomo-graphy (78%),transorbital(59%), transcranial(56%) and panoramic(48%)radiography. 2. The location of erosive lesion that showed the highest detectability was the medial third in panoramic, the lateral third in transcranial, the central portion of anteroposterior direction in transorbital, the central portion of mediolateral direction and the posterior third in lateral tomography. Frontal tomography disclosed all erosive lesions except one anterolateral lesion. 3. The detectability of osteophyte was 100% in lateral tomography, 78% in transcranial and 56% in panoramic radiography. 4. For flattening, lateral tomography showed the flattened condyle, but both panoramic and transcranial views showed only decreased bone density without the change of condylar shape.

Objectives : The purpose of this study was to investigate the stress coping strategies and psychological charactehstics, such as combined psychopathology and tendency of symptom interpretation, in patients with somatization disorder. Methods : Thirty patients meeting the criteria of DSM-IV somatization disorder were compared with thirty controls. We evaluated the subjects using Symptom Checklist-90-Revised (SCL-90-R), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and The Ways of Stress Coping Questionnaire (SCQ). Independent t-test and Pearson correlation analysis were used. Results : From the results of SCL-90-R subscales, the scores of somatization, obsession-compulsion, depression, anxiety, and psychoticism were significantly higher in patients with somatization disorder than nonnal controls. Somatization disorder patients had greater amplification of physical sensation in SSAS and significantly higher score in physical interpretation of SIQ compared with psychological or environmental interpretation, In the SCQ of somatization disorder patients, we observed generallylower levels of total coping scores than the control group and significant positive correlation between passive coping style of SCQ and psychological interpretation of SIQ. Conclusion : These results show that patients with somatization disorder have various psychopathology, greater amplification of physical sensation, physical interpretation tendency of symptoms, and insufficient copying strategy.

For the purpose of determining the reference value of erythrocyte pyrimidine 5'-nucleotidase(P5N) activity as a biological indicator to lead exposure, this study was conducted on the total of 225 healthy men who had not been exposed to lead occupationally, in July, 1994. The parameters selected in this study were age, hemoglobin, hematocrit, number of red blood cell, mean corpuscular hemoglobin(MCH), mean corpuscular hemoglobin concentration(MCHC), blood lead, and erythrocyte P5N activity. The blood lead concentrations were measured using a flameless atomic absorption spectrophotometer, and erythrocyte P5N activities by Sakai's simple method using a HPLC(1986). The results were obtained as follows ; 1. The distribution of blood lead concentrations revealed log-normal distribution, and geometric mean and standard deviation of blood lead were 4.09 ㎍/dl and 1.55㎍/dl, respectively. 2. The erythrocyte P5N activity showed normal distribution, and the mean and standard deviation of the erythrocyte P5N activity were 12.34 μmole uridine/h/g Hb, respectively. 3. All of the selected variables including blood lead concentration did not affect the erythrocyte P5N activity. Although the erythrocyte P5N activities were negatively associated with blood lead level, the correlation coefficient was not statistically significant. 4. From the result of this study, 8.7 μmole uridine/h/g Hb was obtained as a reference value of erythrocyte pyrimidine 5'-nucleotidase activity for the healthy adult male who had not been exposed to lead occupationally.

Lymphangiomas are uncommon benign congenital tumors. Most occur in the head and neck and most lesions present by the age of 2 years. We present our experience with four patients who have iymphangiomas of the head and neck with tongue involvement. First case is a 7-year-old male who has the cystic iymphangioma of left submandibular area. Second a 22-year-old female has a lesion involving the border outright tongue. Third case is the iymphangioma which occurs in the right upper lip of a 6-year old male. The last patient is a 28-year old male who fell down and whose right face was swollen up. He had undergone an operation and been treated with steroid before. The characteristic appearances of imaging methods were described and all lesions best depicted on T2-weighted images. Our experience indicates that MRI is useful in the diagnosis and treatment planning of iymphangioma. (Korean J Oral Maxillofac Radiol 2000; 30: 87-91)
