This study compared the dentin adhesion to composite resin according to air-dry, blot dry, application of rewetting agent on air-dry or blot dry dentin surface by microleakag test and SEM observation. For microleakage test, class V cavity preparations with dentinal margins were prepared on both buccal and lingual surfaces of 40 extracted human molars. For SEM observation, occlusal dentin of 20 extracted human molars were exposed. After etched the dentin, prepared teeth were randomly divided into four groups; D group: air dry for 10-15 sec., B group: blot dry with moist cotton pellet, D-R group: air dry and rewet with Aqua-Prep F for 20 sec., B-R group: blot dry and rewet with Aqua-Prep F for 20 sec. Treated cavities and surfaces were filled or constructed using One-Step adhesives and Aelitefil composite resins. Specimens were stored in distilled water for 24 hours. For microleakage test, the specimens were thermocycled and soaked into 2% methylene blue. The specimens were sectioned longitudinally and evaluated for microleakage under steromicroscope. The data were statistically analysed by Kruskal-Wallis Test, Mann-Whitney and Wilcoxon signed ranked tests. For SEM observation, the specimens were bisectioned mesiodiatally. After decalcified and deproteinized, specimens were observed under SEM. The results of this study were as follows; 1. The microleakges on dentinal margin were the highest in D group compared with B group, D-R group, and B-R group(p<0.05). But there was no significant difference between B group, D-R group and B-R group. 2. D group showed gap and a few resin tags between dentin and composite resin. 3. B group, D-R group, and B-R groups showed close adaptation between dentin and composite resin. It showed that resin rags in B group were numerous and long, in D-R group were few and short, in B-R group were numerous and short or long. 4. Adhesive layer showed in D-R group (10 microm) and B-R group (3 microm) In conclusion, use of rewetting agent to dry dentin was efficient to dentin adhesion, also it did not provide reverse effect on blot dry dentin.

BACKGROUND: Generalized aggressive periodontitis (GAP) is a destructive periodontal disease that can develop in young age. Only a few cases of full mouth rehabilitation, using dental implants, have been reported in a patient with aggressive periodontitis. CASE DESCRIPTION: This clinical report describes the treatment procedures and results of full mouth rehabilitation in a patient with aggressive periodontitis. After all teeth were extracted, 6 implants were placed in the maxilla and mandible, respectively. Fixed detachable implant prostheses were made. The patient was satisfied with the final results. She was followed for 10 months postloading. CLINICAL IMPLICATION: For a long-term success, continuous maintenance care is critical, as the contributing factors of the disease (such as immune factors or periodontal pathogens) may not be controlled adequately.

Nineteen patients with lichen striatus were investigated by clinical data, clinical photographs and histopathologic study by the pattern analysis method of Ackermsn. Results were as follows '. 1. The male to female ratio was 1: 1.1, and average age was 7.8 years. Seven- teen patients (about 90%) visited hospitals during summer season. 2. Nine cases showed superficial perivascular dermatitis, 9 cases interface dermatitis (vacuolar type : 7, lichenoid type, 2), 1 case nodular dermatitis and 2 rases interface dermatitis with nodular dermatitis. 3. In the epidermis, 9 cases showed variable nurnber of dyskeratotic cells. One case showed finding of perforating lichen striatus. 4. Two cases showed inflammation around acrosyringium, 4 cases around hair follicle, 6 cases around eccrine sweat gland and 1 case showed perineural inflamrnation. Summarizing above results, histopathology of lichen striatus characteristically shows superficial perivascular dermatitis, interface dermatitis, and infiltration of inflammatory cells around the sweat gland, which helps to diagnose the disease.

This study was made to evaluate the effect of oral atenolol, a cardioselective beta-adrenergic blocking agent without intrinsic sympathomimetic activity, on left ventricular function in patient with essential hypertension. Atenolol, 100mg/day, was given to 11 hypertensive patients for 4 weeks, and its effects on arterial pressure, pulse rate, left ventricular dimensions and ejection phase indices of myocardial performance were examined by echocardiography. Echocardiographic studies were performed before treatment and after 4 weeks of atenolol therapy. Arterial pressure fell form 145/90 mmHg to 138/84mmHg after 4 weeks. Pulse rate fell significantly from 69/min to 58/min(p<0.05). Left ventricular end-diastolic and end-systolic dimensions and mean rate of circumferential fiber shortening(mVcf) did not change significantly. Ejection fraction increased significantly from 0.66 to 0.72(p=0.01). This results indicate that atenolol in the resting state has no depressant effect on left ventricular function in patients with essential hypertension.

PURPOSE: To investigate the clinical characteristics of retinopathy associated with systemic lupus erythematosus (SLE) and its risk factors. METHODS: Medical records of patients who were diagnosed with SLE were reviewed retrospectively. The presence of retinal hemorrhage, vasculitis and a cotton wool patch were regarded as lupus retinopathy, but concomitant diabetic retinopathy and hypertensive retinopathy were excluded from the study. The correlation between the development of lupus retinopathy and the presence of positive autoantibodies was also investigated. RESULTS: Ocular morbidity was found in 173 of 260 (66%) SLE patients. Retinopathy was detected in 52 eyes of 33 patients (12%), which included 36 eyes of 21 patients (63%) with classic retinopathy and 11 eyes of 10 patients (30%) with vaso-occlusive retinopathy. The presence of classic retinopathy coincided with the flare-up of lupus activity and completely resolved without visual impairment. However, vaso-occlusive retinopathy was not related with lupus activity, and resulted in significant visual impairments of 20/200 or less in six eyes of five patients. The disease activity of lupus assessed by the maximum SLE disease activity index was higher in patients with retinopathy (p<0.05), and the prevalence of antiphospholipid antibody was higher in patients with vaso-occlusive retinopathy than in patients with classic retinopathy (66.7% vs. 37.5%, p<0.05). CONCLUSIONS: Vaso-occlusive retinopathy in SLE can result in permanent visual impairment. Patients with high SLE activity or positive anti-phospholipid antibodies have a high possibility of developing SLE retinopathy and should be referred for ophthalmologic examination.
