The objective of this in vitro study was to evaluate the efficacy of a Ca(OH)2 removal before and after early coronal flaring using different types of instruments. 100 plastic blocks with 30degrees artificial curved canals were used in this study and randomly divided into a control group and 4 experimental groups(GG, OS, GT, PT Group) 20 teeth each. The canals were instrumented, and Ca(OH)2 was temporary filled into the each canal. Irrigation was performed with Max-i-Probe 25-, 30-gauge probes before and after recapitulation. The results of this study were as follows: 1. There were no significant difference among the groups in size of irrigating needle(p<0.05). 2. There was a significant difference between before and after recapitulation regardless size of irrigating needle(p<0.05). 3. Before recapitulation, there was a significant difference between 25- and 30-gauge needle in all groups(p<0.05). 4. After recapitulation, there was a significant difference between 25- and 30-gauge needle in the control group(p<0.05). But there were no significant difference among the experimental groups. It is concluded that the effectiveness of canal irrigation was decided to the depth of irrigating needle into the canal. The effect of canal irrigation tend to facilitate by the early coronal flaring. The recapitulation was the most effective during canal irrigation regardless the size of irrigating needle. Therefore, the recapitulation is a mandatory way to facilitate the effectiveness of canal irrigation during canal enlargement.

The authors analysed the findings of discograms in the 1355 levels of 900 herniated lumbar disc cases during May 1984 to January 1987. Prior to intradiscal injection of Chymopapain in the treatment of lumbar disc herniation, Conray contrast medium was injected. The discographic patterns were devided in five types:I) contained, II) degenerative, III) annular bulging, IV) subligamentous leak, and V) epidural leak type. Among the 5 types, annular bulging type was most common(38.7%). Discography was useful in the determination of a needle placement, intradiscal pathology, and Chymopapain injection or not.

A case is presented of tension pneumothorax during internal jugular catheterization. Pneu- mothorax is one of complications of internal jugular catheterization but is very rare. If it occurs after anesthetic induction, discontinuence of N2O is very important in order not to inerease the size of pneumotborax. And if general safety measures are observed such as uae of fine locator needle, confinement of needle depth and cannulation in end-expiratory phase, the occurrence rate of pneumothorax during the procedure could be much lessened.
