Idiopathic calcinois of the scrotum which was described by Shapiro et al. in 1970 is a rare cutaneous disorder and it seems that this is tbe first case reporting in Korean literature. A 26-year old male was well until age 25 when a few, small nodule developed on the scrotal area and, thereafter, have increased in the numbers and size of the nodules progressively. The skin lessions showed multiple, yellowish, firm, round, smooth nodul ranging in size from that of the head of a pin to that of a pea. Clinica,lly they seemed to be steatoma, but histologic findings showed several islands of calcified amorphous material without: any evidence of residual cysts. He appeared to be in good general health and had an apparently normal skin except for hie scrotum.

As an optimal quality of the restorations, there should be a least amount of seating discrepancy between the casting and abutment teeth. However, high viscosity of the cementing medium and its resulting thickness ay prevent complete seating of the restoration. The use of die spacing material provides adequate internal relief for the cementing medium. The purpose of this study is to compare the thickness of three commonly used die spacing materials. Materials and Methods : Stone plates were fabricated and divided into 12 sections to be painted with die spacers. Tru-Fit, Whip-Mix and Belle de St. Claire die spacer which are commonly used in dental practice were tested in this study. Each die spacers were painted layer by layer according to the manufacturer's recommendation. The average thickness of each die spacers were measured with light microscope(x100) and compared between them. Results and Conclusions: A silver-colored Tru-Fit die spacer has the lowest value of thickness without statistical significance comparing with a gold-colored Tru-Fit die spacer and a gray layer of Whip-Mix die spacer has the highest value of thickness without any statistical significance comparing with Belle de St. Claire die spacer. Three and four layers of Tru-Fit die spacer and two layers of Whip-Mix and Belle de St. Claire die spacers seem to be in the acceptable range of thickness of 25 to 45micrometer for optimal seating of the restorations. The standard experimental design and method should be further evaluated for more consistent and objective results.

In order to compare the changes of dentofacial skeleton, teeth and soft tissue profile in Class I malocclusion patients treated with and without extraction, cephalometric radiographs were taken in 22 female patients as extraction group and 23 female as nonextraction group who were treated in the Department of Orthodontics in Chonnam National University Hospital. The results were as follows. 1. At the beginning of treatment, average age was 19.0 years in extraction group and 15.9 years in nonextraction group. Duration of treatment was 2.8 years in extraction group and 1.7 years in nonextraction group. 2. Before treatment, there were significant difference between 2 groups in the amount of protrusion and proclination in upper and lower central incisor and lower lip protrusion. After treatment, these differences were decreased. 3. In comparison before and after treatment in extraction group, upper and lower central incisor protrusion and lower lip protrusion were significantly improved. In nonextraction group, retrusion and improvement of inclination of upper and lower central incisor were not found.

We report a case of kerion celsi caused by Trichophyton verrucosum in a 4-year-old male. He presented painful, tender, indurated, boggy masses discharing pus on the vertex and occiput. Kerion celsi caued by T. verrucosum was diagnosed by the characteristic gross and microscopic findings of the colony on the Sabourauds glucose. agar. The possible source of infection was searched and wq found that he raised the cattles in his house. They had multiple, scaly, whitish plaques on the skin and T. verrucosum was identified from the hairs of the lesions. He had been treated with griseofulvin and prednisolone, and all lesions were cleared leaving partial alopecia in 2 months.
