The purpose of this study was to investigate the causes of food impaction and to explore solutions as well. For this study, 39 patients with food impaction wee selected. 77 contact areas in these patients were investigated mobility, tightness of contact area, gingival index, plaque index, attachment loss, alveolar bone loss, proximal caries, marginal ridge distance and occlusal relationships. The results were as follows ; 1. Teeth without distal support were found to be the most frequent site of food impaction (41.6%). Food impaction was found to be more frequent in the upper teeth (66.2%) than the lower teeth (33.8%). 2. Food impaction was found in tight contact cases (71.4%). Alveolar bone loss was not found in the early stage of food impaction (83.1%) 3. The distance between the marginal ridges of food impaction sites (mean=0.48mm) was shorter than that of the control group. (mean=0.77mm) (p<0.001) 4. In 18.2% of t he cases, proximal carries were found at the food impaction site. 5. Food impaction affected patient's occlusion with the following frequencies ; cusp to marginal ridge relationship (72.7%), cusp to fossa relationship (3.9%) and stepped relationship (23.4%).

A retrospective study was made of the previous medical records of 32 infants with congenital syphilis borne from mothers with untreated syphilis at Severence Hospital, Yonsei University College of Medicine during the years 1,972 through 19g3, These infants had a VDRL titer higher than 1: 8 with reactive FTA-ABS test and were also subjected to radiologic examinations. Radiologic changes and clinical features were analyzed, The following results were obtained: Of the total of 32 infants with congenital syphilis under 5 months of age, those under 1 month of age, were the most common group numbering a total of twelve. Of 32 infants with congenital syphilis, twenty-nine(91%) showed skeletal changes upon radiologic examination, Among them the different sites of bone involvernent revealed that the femur(92%) was the most commonly affected bone, followed by the humerus(88%), tibia(81%,), fibula(80%), ulna(72%), radius (68%). Among the same 29 infants a study of the presence of various abnormal bone changes showed that periostitis was the most common, being involved in 83%, the others being metaphysitis and periostitis(72%), metaphysitis(66%). 3. Among the clinicaI features presented in the 32 infants with congenital syphilis, hepatomegaly was the most common(63%,), followed by erythema with desquamation(47%), pneumonia(38%), maulopapules(34%).

Five volunteers received patch tests with 5% sodium lauryl sulfate (SIS) in solutions of differing pH. The irritant effect was monitored by visual scoring as well as by a laser Doppler vlelocimeter, evaporimeter, cutometer, and colorimeter. The non-invasive methods used in this study with the exception of the cutometer were effective in the evaluation of skin irritation. No significant differences in the skin responses to SIS in different pH solutions were found either clinically or by the non-invasive methods used for quantification. It was concluded that the pH of SIS is not a major factor in the degree of skin irritation produced by SIS.

The purpose of this study was to compare the wear characteristics of Type III Gold Alloy (Degular C; Degussa AG), VMK 95 (Vita Zahnfabrik), Vitadur Alpha (Vita Zahnfabrik), IPS Empress (Ivoclar-Vivadent) and Targis (Ivoclar-Vivadent). Ten samples of each material were abraded against enamel of extracted incisors for 160,000 cycles on the wear machine. The depth of wear scars on enamel was analized with profilometer (Alpha-step 200; Tencor). And the wear of material specimen was determined with micrometer (PB-1B; Mitutoyo Co. Japan). The results obtained were as follows : 1. Type III gold alloy (2.47micrometer) and Targis (5.89micrometer) caused less wear of enamel specimens compared to VMK 95 (75.59micrometer), IPS Empress (78.60micrometer) and Vitadur Alpha (78.89micrometer) (p<0.05). 2. The wear of material specimen when opposing enamel was the lowest in type III gold alloy (3.0micrometer), followed by Targis (69.8micrometer), IPS Empress (148.4micrometer). VMK 95 (298.0micrometer) and Vitadur Alpha (300.8micrometer) exhibited the most severe wear against enamel (p<0.05).
