Congenital hereditary disease is in devided into Infantile type and Adult type, Adult type is hidden for many years and keeps normal renal function till middle age. Cyst is stimultaneously made in both sides and becomes lowered in renal function in 30's to 40's. Infantile type is generally born with the big kidneys, renal failure, undergrowth of intrahepatic bile duct. Both infantile and childhood type have ureteral dilatation and portal hypertension In infantile type, it is mostly developed into renal failure, but generally faces death as a result of hepatic disease. The reason of death is that an abnormal condition of recessive autosome affects the liver and kidneys. While the incidence of infantile type is rare as $0.017{\sim}0.07%$ and it is autosomal recessive heredity, Adult type can rarely exist in infantile period. Though it exists in middle period, 50% of patients can live for 2-4 years after the first symptom incidence and 25% can less than 2 years. It is hard to cure completely in medicine and surgery. Three difficulties in familial incidence are comparative decrease of the donor who have no affection on renal transplantation. For another consideration it is to show the family history for several generations. We, the Med. Dept. of Dae Han Kyouk Life Insurance Co. Ltd., used the ultrasonic apparatus in diagnosing the one case of adult type bilateral polycystic kidney and then doubted the family history. As a result of inspecting the family we experienced bilateral polycystic kidney from 3 persons out of 4 who can be inspected. The results are as follows: 1) We could confirm the polycystic kidney from 3 persons out of 4(75%). 2) Then when they came for check up, chief complaint was the pain in all 3 cases(100%). 3) Accompanying disease was hypertension in 2 cases(67%). 4) In early disease incidence, we couldn't observe the specific change in pathological opinion. 5) All 3 cases are not accompanied with cystic lesion in liver, spleen, pancreas.

We have reviewed 157 cases of coarctation of aorta in the age of infancy and children from March 1973 to december 1994. Patients were 9) males and 64 females, and their age ranged from one month to fifteen years (23.8 $\pm$ 41.6months) with 113 infant cases. In the infantile age, congestive heart failure was the most common chief complaint (781113), and above that age, asymptom was most common (15/44). Isolated coarctation was present in 31 patients, and 9 patients had additional atrial septal defect (group I), 73 patients had associated ventricular septal defect (group II), and 44 patients had associated complex intracardiac lesions(group III). Aortic arch hypoplasia was present in 17 patients. , The operations perf'ormed were subclavian flap angioplasty in 71 patients, resection and anastomosis in 32 patients, patch aortoplasty in 26 patients, resd extended end-!o-end anastomosis in 27 patients, and direct angioplasty with resection of web in 1 patient. The early mortality was 17.2% (27/157) and re-coarctation rate was 18.0% (281157). The most common complication was respiratory problem in infants and postoperative hypertension in children.

Likely to be the most common oral cancer, squamous cell carcinoma(SCC) of the tongue accounts for about 20% of all oral and pharyngeal cancers. SCC of the tongue frequently arises in the lateral border, and if it metastasize, it occurs on submandibular gland and neck lymph nodes. Location of the primary lesions and neck lymph node metastasis affect the prognosis and decrease survival rate of patients with carcinoma of the tongue. The authors experienced the patient with contralateral neck lymph node metastasis of SCC of the tongue. The patient came to our department with chief complaint of elevated lesion on left lateral border of the tongue. The mass was diagnosed as $T_2N_0M_0$, Stage II invasive SCC of oral tongue. Computed tomography(CT) & magnetic resonance imaging(MRI) which were taken before the operation showed no significant finding of metastasis. Surgical mass removal and preventive neck dissection on the left side were done. While follow up PET/CT, contralateral neck lymph node metastasis(right side, level II) was detected, and re-operation(Rt. side RND) was done. There are few studies concerning the contralateral neck lymph node metastasis related with SCC of the tongue. The purpose of this report is to introduce the uncommon case of contralateral neck lymph node metastasis occurred in the $T_2$-stage of SCC of the tongue treated by surgical resection.

Cerebral palsy(CP) is one of the most common motor disease, due to brain injury during fetal and neonatal development which results in neuromotor paralysis and associated neuromuscular symptoms. Features of CP include motor disability due to the lack of muscle control, often accompanied by sensory disorders, mental retardation, speech disorders, hearing loss, epilepsy, behavior disorders, etc. There are increasing chances of treatment of dental patients with cerebral palsy, as the occurrence of CP is increasing with the decrease in infant mortality and an increase in immature birth and premature birth and also, there is a trend to pursue of higher quality of life. Reports on the relationship between CP and maxillofacial deformity are uncommon, but it is well known that the unbalance and discontrol of the facial muscles, lip, tongue and the jaws leads to malocclusion and temporomandibular joint disorders, and statistics show that class 2 relationship of the jaws and open bite is frequently reported. However, it is difficult to perform maxillofacial deformity treatment, which consists of orthodontic treatment, maxillofacial surgery and muscle adaptation training, due to difficulties in communication and problems of muscle adaptation caused by difficulties in motor control which leads to a high recurrence rate. This case report is to trearment of maxillofacial deformity in CP patient. A 26 year old female patient came to the department with the chief complaint of prognathism of the mandible and facial asymmetry. According to the past medical history, she was diagnosed as cerebral palsy 1 week after birth, classified as GMFC, classII accompanied with left side torticollis. The patient's intelligence was moderate, and there were no serious problems in communication. For two years time, the patient underwent lingual frenectomy, pre-operation orthodontic treatment and then bimaxillary orthognathic surgery to treat mandibular prognathism and facial asymmetry followed by rehabilitatory exercise of facial muscle. After 6 months of follow up, there was a good result. This is to report to the typical signs and symptoms of DFD in CP patient and the limitation of the usual method of the treatment of DFD in CP patient with literature review.

Traumatic bone cyst is a nonodontogenic cyst without epithelial-linig which contains fluid in it's cavity, and it is limited by bone walls with no evidence of infection. Traumatic bone cyst is asymptomatic and appears more frequently in the second decade. Gender distribution is approximately equal, although males are affected slightly often than females. Radiographically the lesion shows a well demarcated radiolucent lesion of variable size and the lesion may have scalloped margins. The adjacent teeth to traumatic bone cyst remains vital. Traumatic bone cyst is usually treated by surgical exploration and currettage of the lesion. In the first case of this case report, the patient was refered from the local dental clinic for the radiolucent area under the left mandibular first molar. From the panorama radiograph at the first visit, the radiolucent area of the left mandible showed a well defined scalloped margin and identified as traumatic bone cyst. In the second case, the patient have visited for the chief complaint of swelling and abcess of right maxillary second premolar. In the radiographic check up with panorama radiograph, the radiolucent lesion with well demarcated scalloped margin was found in the right mandible body, and identified as traumatic bone cyst. In the first case, overinstrumentation was done through the mesial root canal to irrigate the lesion. In the second case, not any treatment was done, and watched the progression of the lesion. And in both cases, after two month, the radiolucency and the size of the lesion has decreased to show healing in progress.

Although most cases of tension-type headache(TTH) are myogenic headache, in some cases, arthralgia appears, such as the disorder of the temporamandibular joint. This study is designed to compare the clinical patterns of arthralgia to those of myalgia, when both symptoms are co-existing. Among 167 patients who visit our clinic during a certain period, whose chief complaint was TTH, 18 patients were the arthralgia group, 50 patients were the myalgia group, and 99 patients who have both arthralgia and myalgia were the arthromyalgia group. Three groups were asked to answer the questionnaires about their age, gender, and oral parafunction such as bruxism or clenching. Then we gathered statistics on the data from the accomplished questionnaires. 1. There was statistical significance in age among the three groups(p=0.02). 2. There was no statistical significance in sex and oral parafunction among the three groups. 3. There was statistical significance the myalgia group was older than the arthromyalgia group(p<0.03). The results of the study show that as patients become older, TTH with myalgia happens more frequently than TTH with arthralgia and myalgia does.

Excessive occlusal wear results in unacceptable damage to the occluding surfaces, and can cause pulpal injury, occlusal disharmony, impaired function, and aesthetic deformity. Patients with severely worn dentition need to be classified as several categories relative to the vertical dimension of occlusion (VDO) and the interocclusal distance for the prosthetic space. When treating patients classified as those who have excessive wear without loss of occlusal vertical dimension but with limited space, we could consider treating them at an increased vertical dimension of occlusion. Treatments at an increased vertical dimension of occlusion may provide stability, given that the amount of its increase was minimal, and a perfected occlusion was achieved after enough stabilization period. A 50-year-old male visited the department of Prosthodontics in Yonsei University Dental Hospital with the chief complaint of worn teeth on lower anterior area. Reconstruction at an increased vertical dimension of occlusion was planned. After the compatibility of the new vertical dimension of occlusion had been confirmed under interim fixed restorations, definitive fixed restorations composed of full-contour monolithic zirconia prostheses were placed. This case presents that a satisfactory clinical result was achieved by restoring the worn dentition at an increased vertical dimension of occlusion with an improvement in esthetics and function.

Esthetics is important in restoring maxillary anterior area. Alveolar bone resorption and loss of interdental papilla may be minimized by immediate implantation. Previous studies showed successful results with the immediate implantation in healthy extraction socket, while many of these studies objected the immediate implantation into extraction sites with periapical lesions. Recent studies, however, reported successful results of the immediate implantation into extraction sites with periapical lesions with careful debridement of extraction sockets and general medication of antibiotics prior to implantation. A 73-year-old female visited the department of Prosthodontics in ${\bigcirc}{\bigcirc}$ University Dental Hospital with the chief complaint of fallen post-core and crown on left maxillary incisor. Although the incisor was with vertical root fracture and periapical lesion, the immediate implantation following the extraction of tooth was planned. Thorough socket debridement, irrigation with chlorhexidine, and tetracycline soaking were followed by immediate implantation. The general medication of antibiotics (Moxicle Tab.$^{(R)}$, 375 mg) was prescribed before and after the surgery. Immediate provisional restoration was delivered two days after the surgery, and the definitive metal-ceramic restoration was placed about six months later after reproducing the emergence profile from the provisional restoration. This case presents satisfying result esthetically and functionally upto two years after the placement of prosthesis with the harmonious gingival line and no loss of marginal bone.

Complete denture prosthodontics includes replacement of natural teeth and associated maxillary and mandibular structures for full edentulous patients. The final objectives of prosthodontic treatment include esthetic and functional rehabilitation. Because the esthetic demand of senior patients has increased esthetic requirement should not be overlooked in denture treatment. In complete denture treatment, attempts have been made to reproduce tooth wear, arrangement, recession of cervical gingiva, staining, improved gingival shade and so on. This 61 year old female patient came to the Department of Prosthodontics with the chief complaint that dentures made 5 years ago in a local clinic were broken and did not fit well. The patient put more emphasis on fabrication of natural and esthetic dentures than recovery of masticatory function. Remake of maxillary complete denture and mandibular implant retained overdenture was planned. In order to create esthetic and natural contour, Aesthetic Color Set Easy system$^{(R)}$ (Candulor dental GmbH, Wangen, Germany) was used to make complete dentures reproducing various gingival shades. Patient's esthetic satisfaction was high. When complete denture prosthodontics treatment involves appropriate expression of individual characteristics in addition to proper selection of esthetic materials, treatment will give satisfaction to both dentist and patient.

Trauma from occlusion(TFO) is injury to the periodontal tissue as a result of occlusal forces. Mobility is a common clinical sign of occlusal trauma. In acute occlusal trauma, this may be accomanied by pain, tenderness to percussion, thermal sensitivity, and pathologic tooth migration. Chronic occlusal trauma may be marked by excessive wear and gingival recession. Radiographic finding include a widened periodontal ligament space, radiolucence and condensation of the alveolar bone and root resorption. TFO is related to the pathogenesis of periodontal disease. It can cause increased tooth mobility TFO itself does not initate or aggravate marginal gingivitis or initiate periodontal pockets. Active trauma can accelerate bone loss, pocket formation and gingival recession depending on the presence of local irritants and inflammation. Gingival recession associated with occlusal forces includes traumatic crescent, McCall's festoon and Stillman's cleft. TFO plays a minor role in the pathogenesis of early to moderate periodontitis. A 5-year-old male visited Yonsei University Pedodontics clinic with a chief complaint about gingival recession. Mobility, excessive wear, gingival recession were detected by clinical exam on the both mandibular deciduous ca nine. On the radiographic view, vertical alveolar bone loss was observed on both mandibular deciduous canine.
