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%).

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 heat-pressed technique(IPS-Empress, Ivoclar) has been described to construct single unit crown, inlay/onlay and veneers using a partially pre-cerammed and pre-colored glass-leucite ingot that has the greateast strength by the combination of heat-pressed procedure through the small-diameter sprue and heat treatment procedure. The purpose of this study was to evaluate the flexure strength of a heat-pressed ceramic material(IPS-Empress) without simulated firing treatments according to pontic designs. Two groups of 9 disks(1.4mm thick, 14mm in diameter) each using two types of sprues with different diameters(phi2.8, phi1.8) and numbers were prepared. The specimens were mounted in the testing jig. The flexural strengths were determined, by means of the bi-axial bending test, by loading the center of disk to failure using a universal testing machine(Zwick 145141, Zwick, Germany) at a cross-head speed of 1.0 mm/min. The means flexural strength value of one group using a sprue with phi2.8 was 140.4+/-8.0 Mpa. That of the other group using two sprues with phi1.8 was 151.8+/-10.3 Mpa. After analysis, results showed that there was a statistical difference between groups(t=2.33m p<0.05). No clnical implications were drawn from these data because of absence of simulated firing treatment.
