The purpose of this study was to evaluate the effects of thermocycling on the shear bond strength of Co-Cr alloy to denture base resin. PMMA denture base resin such as heat-cured Vertex-RS , self-cured Vertex-SC and 4-META denture base resin such as heat-cured Meta-Dent , self-cured Meta-Fast was bonded to Co-Cr alloy. Samples were divided into 3 groups : no thermocycling group as control, thermocycling between 5degrees C and 55degrees C with 15 second dwell time as group 1, thermocycling with 1 minute dwell time as group2. The shear bond strength was measured and the interface between metal and resin was observed by SEM. The results were as follows. 1. The shear bond strength decreased significantly according to thermocycling and dwell time(P<0.001). 2. The bond strength of Co-Cr alloy and 4-META denture base resin was significantly higher than that of Co-Cr alloy and PMMA denture base resin(P<0.001). 3. IN SEM, there was no gap in control group, but there was much and large gap in group 1, 2. The longer dwell times, the lower bond strength. PMMA denture base resin had more gap than 4-META denture dwell times, the lower bond strength. PMMA denture base resin had more gap than 4-META denture base resin in the interface. These results revealed that thermocycling decreased the bond strength between Co-Cr alloy and denture base resin and dwell time of thermocycling changed the effect of thermocycling. The results suggested that oral temperature change affect the bond strength of prosthesis.

Lidex' cream (Fluocinonide 0.05% in FAPG base) is a new fluorina,ted topical corticosteroid, and its clinical effect was assessed by applying topically three to four times daily to the lesions of 50 patients with a variety of inflamrnatory skin condi- tions. The results revealed excellent effect in 16 patients, moderate effect in 23 patients, slight improvement in 9 patients, and no effect in 2 patients. No unfavorable side effects were noted except blanching. The findings suggest that fluocinonide is an excelIent addition to the topical corticosteroid agents that are available for clinical use at the present time.

STATEMENT OF PROBLEM: Several domestic dental implants have been developed since dental treatment being implants are increasing and popularized. However, they have not been used in domestic market like imported goods. MATERIAL AND METHODS: This study was carried out to compare domestic and imported implants in aspect of fitness, dental implant fixture and abutment screw using scanning electron microscope. All experiments were performed under dry condition. RESULTS: 1. Only in aspect of relation of dental implant fixture and abutment screw, except only one group with point contact, good fitness was existed. 2. Home products must presevere in their efforts, so as excellent to fit.

The authors report a case of ectopic paragonimiasis in a 33 year old Korean housewife who came to the hospital because of lower abdominal discomfortness and palpable mass. Parasitic granulomas involved the ovary and posterior wall of the uterine body. This report deals with the rare occurrence of a parasitic infestation in the ovary.

A case of unilateral multicystic renal dysplasia was reported in view of rarity, and a review of literature 23-year-old female was admitted to Kyung Hee University Hospital with a complaint of urinary incontinence. An excretory urogram revealed non-visualization of the right kidney. The right ureter had opening at the 2 cm above the vaginal introitus. The resected right kidney revelaed multilobulated outer surface with multiloculated cystic struture on cut surface. The associated anomaly was uterine didelphy. The condition was treated by nephroureterectomy.
