One of the characteristics that can predict the cariostatic effect of dental pit and fissure sealants is wear resistance of the material, and those for the expectation of the retention rate is the bond strength to enamel. Although the Bis-GMA resin based sealants are widely used, their mechanical properties are lower than those of composite filling resins because of lower cross-linking of the material. After incorporation of filler to the resin sealant, almost all the mechanical properties are improved except tensile strength. Incorporation of filler also results in higher abrasion resistance, and easy discrimination of the sealant. However there are a few reports on the mechanical properties and bond strength of sealant after incorporation of various amount of filler to the same resin for sealant. The purpose of this study was to determine the bond characteristics to enamel and the biaxial fracture strength of dental pit and fissure sealants after incorporation of various amount of glass fillers to the same unfilled resin sealant. Light cured pit and fissure sealants(CO and TM) were used as controls. Glass filler was incorporated in the chemically cures resin sealant(HP) with the ratio of 10, 30 and 50 wt.%, and was used as experimental groups, Two types of fillers, silane-coated and not coated, were used. For bonding test, flat enamel surface was made on sound premolar tooth by grinding with #600 silicone carbide paper. This surface was ached with 37% phosphoric acid for 30 second, and sealant filled gelatin capsule(3㎜ diameter) was attached to this surface. After immersion in 37% distilled water for 24 hours, shear bond properties were measured with a universal testing machine(Zwick 020, Germany) with the cross-head speed of 1㎜/min. From the lid-deflection calve obtained, shear bond strength, displacement at bond failure and elastic modules ratio was calculated. For biaxial fracture strength test, diameter of 10㎜ and thickness of 2㎜ specimens were made with the same materials as in bonding test. After immersion in 37℃ distilled water for 24 hours, biaxial fracture properties were measured with a universal testing machine(Zwick 020, Germany) with the cross-head speed of 0.5㎜/min. From this experiment, the following results were obtained. 1. The shear bond strength of unfilled HP to enamel surface was 13.870㎫, and those after filler incorporation were 18.956-19.684㎫. 2. The shear bond strength to enamel surface increased significantly after incorporation of filler with the ratio of 10, 30 and 50 wt.%(p<0.05), and the incorporation ratio did not influence on the shear bond strength(p>0.05). Silane treatment of the filler did not influenced on the shear bond strength(p>0.05). 3. The biaxial fracture strength of TM was 170.69㎫, and this was significantly higher than that of unfilled HP(p<0.05). Incorporation of the filler with the ratio of 10, 30 and 50 wt.% resulted in significantly lower biaxial fracture strength compared with that of unfilled HP(p<0.05). 4. In HP with the incorporation of filler 10 or 30 wt.% group, the biaxial fracture strength of silane coated and not-coated filler group was significantly different(p<0.05).

Several methods for the management of intractable pain for various conditions including malignant disorders, herpes zoster, and low back pain and/or sciatica in 80 patients were described and analyzed. Neurolytic blodks of celiac plexus were given to the patienta suffering from intra-abdominal pain from malignant origin or chronic pancreatitis. Herpes zoster was treated mainly by chemical sympathectomy via paravertebral route and occassionaly corticosteroid was administered epidurally with the local anesthetic, bupivacaine. All the patients with low back pain and/or sciatica were given epidural corticosteroid one to three times. Other peripheral verve blocks and regional corticosteroid therapy were given to the rest of the patients. Fair to excellent result was obtained in 71% of the patients but the response was poor in the remaining 28% of the patients. It seems that the earlier the patients were referred to the pain clinic, the better the results were.

Lidocaie으로 試圖한 脊椎麻醉의 臨床經驗 : 2170 症例 2170 cases

This study was primarily undertaken to assess the value of lidocaine as a spinal analgesic for lower abdominal surgery because of the many advantages of it. However, lidocaine has been little used for spinal analgesia in spite of the fact that the use of it has been well publicized by T. Gordh, Barbara W. Adams and Otto C. Phillips. This is the 1st attempt to use lidocaine in Korea for a spinal analgesia. Since 1974, 2170 cases of spinal analgesia using premixed lidocaine solution(5% lidocaine+5% dextrose) were recorded by the Dong San Medical Center, describing the merits, storage of premixed solution, caramerization when autoclaving and the disadvantage of premixed lidocaine solution. According to the previous reports by Phillips and Adams, lidocaine spinal anesthesia was used mostly for vaginal delivery, prostatectomy, and perineal procedure. The dose of lidocaine ranged from 40㎎ or less to 100㎎, However, in this study, most lower abdominal surgery and lower extremity procedures were performed under lidocaine spinal anesthesia in doses ranging between 100 to 200㎎. Also, high and total sipnal anesthesia was induced using large doses of 5% lidocaine of 300㎎ to 750㎎ for upper abdominal operations such as cholecystectomy, gastrectomy, mastectomy, and tonsillectomy. The duration was about an hour for cesarean section when 75㎎ of lidocaine was used, about one and a half hours was utilized for ordinary lower abdominal surgery when 100㎎ to 200㎎ of lidocaine was used. As a result of this study, we can summarize as follows: 1. The lidocaine that is an amide derivative is an excellent substitute for pontocaine which is an ester compound to obtained good analgesia for lower abdominal surgery. 2. The premixed solution (5% lidocaine+5% dextrose) can be stored at room temperature safely for many years without decomposition of the mixture or affecting the anesthesia effect. 3. 5% concentration of lidocaine was adequate and convenient clinically. Please note that a 5% dextrose solution was most suitable in this premixed hyperbaric solution (S.G. 1021) to prevent caramelization during autoclaving. 4. At the onset of action, lidocaine was rapid, therefore patients were able to feel the effect almost instantaneously at injection time. 5. No anesthetic failures from lidocaine were observed and the onset of action was clear and well marked. This was in contrast to the failures observed when using pontocaine occasionally. 6. Large doese of lidocaine were used but no signs of lidocaine toxicity were observed, other than a physiological change from high spinal anesthesia. 7. The lidocaine appeared to have the one disadvantage of poor fixation behaviour, and therefore, there was an increased possibility of hypotension in comparison with pontocaine. These hypotensions can be easily prevented by the intravenous injection of ephedrine. 8. The postspinal complications in Korean patients were closely observed, and deliberate high and total spinal anesthesia were studied in this article. Details will be prepared and reported at a later date. 9. The premixed 5% lidocaine with 5% dextrose was prepared by Dong San Hospital pharmacy.

Various post-spinal complications have been well reported for a century since spinal anesthesia first started in 1885. However, we have no statistics on postspinal complications observed in Koreans. During the five year period from 1974 to 1979, 5318 cases of spinal analgesia, mainly using a premixed 5 percent lidocaine solution with 5% dextrose, were recorded at Dong San Medical Center. This study was primarily undertaken to observe various postspinal complications in Koreans. As a result of this, we can summarize as follows: 1) The mean age of these cases was 43 years. 2) The main anesthetic was the premixed 5 percent lidocaine solution with 5 percent dextrose. 3) The needles for the lumbar puncture were mainly 22 gauge Whitacre pencil point needle. 4) The overall incidence of headache was 3.4 percent. The details as to postspinal headache and treatment were published previously. 5) Backache was subdivided into three different groups: localized pain(3.88%), diffuse pain(2.47%) and radiating pain(0.17%). The overall incidence was 2.7 percent. 6) The incidence of voiding difficulty was 2.7%. 7) The Rare neurological sequelae were not observed in our series and the other complications are noted in table 5. 8) The results are compared with the Dripps and Phillips series in table 2.
