This study was designed to compare the effect of polishing on surface roughness of composite resin. We used Z100(3M) composite resin and placed the composite resin in the hole (4mm thick and 4mm in diameter) of vinyl plate and polymerized it under manufacturer's instructions. Samples were divided into 5 groups by polishing methods. Group 1 was control: resin was polymerized under glass plate, Group 2: resin was polymerized without any polishing procedure, Group 3: resin was polymerized with a polishing procedure of abrasive disc, Group 4: bonding agent was applyed in thin layer an polymerized on the polished polymerized resin surface, Group 5: resin was polymerized under transparent celluloid strip. The surface roughness of each specimen was measured with Sufacoder SEF-30D (Kosaka lab. Ltd) under 0.08mm cut off, 0.05mm/s stylus speed, x40 horizontal magnification, x5000 vertical magnification. The results were as follows : 1. Group 1 showed the most smooth surface in this study. 2. Group 3 showed more rough surface than Group 2. Considering the surface roughness, it would be better to make the shape completely before polymerize the resin. To finish and polish after the polymerization of resin makes less smooth surface. 3. When we use the transparent celluloid strip, minimum finishing procedures are recommended. Any polishing procedure could not recover the smooth resin surface of celluloid strip. 4. Application and polymerization of the thin layer of bonding agent on the polished surface showed the minimum surface smoothing effect.

A 20-year-old man with chronic renal failure had a whitish smooth plaque on his tongue. Due to his long standing illness, he had poor oral hygiene. Histopathologic examination showed marked epithelial thickening with parakeratosis and intracellular edema in the prickle cell layer. PAS staining revealed increased amounts of PAS-positive materials in the pale epithelial cells. His tongue lesion persisted during his hospital course.

We experienced a case of a primary aortoduodenal fistula, which was successfully diagnosed and repaired. This diagnosis must be considered in cases of gastrointestinal bleeding with an abdominal aortic aneurysm. If the correct diagnosis can be made promptly, surgical repair of the fistula is possible.
