Esophageal atresia is the abnormal development of the esophagus that connects the mouth to the stomach. This birth defect results in the incomplete connection of the esophagus to the stomach causing an inability to swallow properly and breathing difficulties. Surgery is the only treatment for esophageal atresia. Patients undergone an esophageal reconstruction usually suffer from gastroesophageal reflex. A 5-year old boy with congenital esophageal atresia and Sciwitar syndrome visited Seoul National University Dental Hospital because generalized excessive loss of tooth structure. The patient had history of multiple operations for reconstruct esophagus. He had little food intake experience thought oral and had difficulty to swallowing. The patient was generalized severe erosive and decayed state. For patient, the dental procedure under general anesthesia was scheduled due to the multiple caries with erosion and poor cooperation. Under general anesthesia, pulpectomy and restoration as well as extraction was performed. Gastroesophageal reflex is potentially serious condition, with various extraesophageal adverse effects such as dental erosion. To prevent progression of dental caries, dietary counselling and oral hygiene instruction should be reinforced. Also, restorations to erosive teeth will maintain esthetics and function and preserve pulp vitality.

Patients who lost posterior teeth due to periodontitis or dental caries have collapsed vertical dimension, unstable occlusion and change of the mandibular position. In particular, patients in orthognathic surgery, clinician should re-establish the pre-operative stable position of mandibular condyle in articular fossa and favorable vertical dimension for high post-operative stability of mandible. Therefore, interdisciplinary approach and co-operation, including prosthetics, orthodontics, oral and maxillofacial surgeon, from diagnosis and treatment plan is important to get a good outcome. This case report was patients who had collapsed occlusal plane due to severe dental caries on maxillary molars with skeletal Class III malocclusion. Before orthognathic surgery, resetting of maxillary occlusal plane with temporary removable denture was performed. Then successful multidisciplinary approach was done and lead to acceptable clinical outcome.

치경부에 발생된 병소 부위(cervical lesion)는 "우식성 병소(caries lesion)"와 "비우식성 병소(non-caries lesion)"로 분류할 수 있다. 우식성 병소는 구강 내 세균들의 활동에 기인하여 발생된 병소로서 경조직 손상 부위의 수복과 함께 우식이 재발하지 않도록 체계적으로 대응하는 것이 필요하다. 비우식성 병소는 산성 물질, 저작력 및 이물질에 의한 마모 작용과 같은 다양한 원인에 의해 발생될 수 있으며, 수복 치료에 앞서 병소에 발생 원인을 규명하는 것이 중요하다. 먼저 병소 유발 원인에 대한 분석과 이에 대한 적절한 조치를 취한 후에 수복 치료를 시행하는 것이 바람직하다. 심미적인 요구가 높은 치경부 병소의 수복을 위하여 사용될 수 있는 재료는 "불소를 방출하는 재료"와 "불소를 방출하지 않는 재료"로 나뉘어지는데, 세균의 활동에 의해 형성된 우식성 병소의 수복에는 불소를 방출하는 재료를 사용하는 것이 추천된다. 우수한 심미성과 보다 강력한 유지력이 요구되는 경우에는 복합 레진계 수복 재료들을 사용하여 수복하게 되는데, 이 경우에는 "접착 술식(bonding procedure)"이 중요한 역할을 수행하게 된다. "접착 술식"은 수복물의 일차적인 유지 뿐 아니라 지각과민을 해소하고 2차 우식을 방지하며, 궁극적으로 수복물의 수명을 좌우하는 결정적인 역할을 수행한다. 자연 치아를 최대한 보존하고자 하는 "최소침습(minimum intervention)" 개념에 바탕을 두고 세심하게 형성된 와동에 각각의 증례에 최적화된 수복 재료를 선택하여 수복치료를 시행한다면 보다 심미적이고 환자가 편안한 치경부 수복물을 완성할 수 있을 것이다.

Prader-will syndrome (PWS) is a genetic disorder displayed with short stature and behavioral problems. The major manifestation is hyperphagia and obesity but there is no known effective drug that can solve this problem. This article presents a case report of a 3-year 9-month old girl affected with PWS syndrome treated under general anesthesia due to lack of cooperation and multiple caries. The dentist should work as a member of the multidisciplinary medical team. Careful long term follow up is required to prevent dental caries and periodontal diseases as well as maintain good oral hygiene. A strict diet control should also be encouraged.

Treacher Collins syndrome(TCS) is a rare, incurable condition occurring in approximately 1 of 25,000 to 50,000 births. It may occur as a spontaneous mutation out of genetically normal parents or it may be manifested as an autosomal dominant pattern. TCS is characterized by facial deformities such as, underdevelopment of the maxilla, mandible and zygoma, malocclusion, bilateral deformities of auricles, antimongoloid slant of the palpebral fissures. The syndrome is often associated with cleft lip and palate, ear malformations and hearing loss, short stature, and anomalies of the heart and skeleton. Respiratory difficulty associated with air way obstruction may also be observed, and there is considerable difficulty in airway management during general anesthesia. It is necessary that dentists provide safe dental treatments and guidelines to TCS patients by providing adequate understanding about the characteristics of the syndrome and proper ways of managements. The purpose of this study is to report the dental and medical characteristics of the patient who visited the Department of Pediatric Dentistry, Yonsei University for multiple dental caries treatment and to review the literatures of TCS.

Lowe syndrome is X-linked gene disorder, characterized by cataracts, renal dysfunction and brain abnormalities. Oral healthcare of young patients with Lowe syndrome could be easily neglected due to the uncooperative behavior or other systemic condition of the child. We are presenting a case of successful treatment under general anesthesia with uncooperative child with Lowe syndrome. A 3-year old boy with Lowe syndrome visited Seoul National University Dental Hospital for multiple caries. He had been suffering from congenital cataract, medullary nephrocalcinosis and hypotonia. Multiple caries were observed from clinical and radiographic examination. Concerning behavior management problem and possibility of aspiration due to hypotonia, dental treatment under general anesthesia was planned. Left upper primary first molar was extracted to prevent further infection. Other teeth were treated with Stainless steel crown or composite resin restoration based upon the extent and the severity of dental caries. Under general anesthesia, dental procedure was carried out successfully and safely. Considering uncooperative behavior and other medical conditions of the patient, general anesthesia could be effective. Home oral care and periodic visit to dental clinic should be emphasized to the caregiver of patient with Lowe syndrome, considering the susceptibility of dental caries and other oral manifestation.

Pediatric dentistry is differentiated from other fields of dentistry in that it provides comprehensive dental care for children and adolescents. In early days, pediatric dentistry used to be confined to the caries treatment and extraction of primary teeth However, the practice spectrum of pediatric dentistry has broadened to the orthodontic, surgical, esthetic and preventive treatments A survey that contained questions about practice patterns were mailed to 50 pediatric dentists, and 21 surveys were returned. Results were as follows: 1. The average number of patients per week was 82.4, and the average number of treated teeth per patient was 2.35. 2. Preventive treatments comprised 15.7%, restorative treatments 55.7%, endodontic treatments 15.6%, surgical treatments 10.5%, and orthodontic treatments 2.4%. 3. In restorative treatments, amalgam restoration comprised 3.8%, glass ionomer 5.5%, composite resin 63.0%, and stainless steel crown 27.7%.

Tooth impaction is defined as a failure of tooth eruption resulting from the physical obstacles in the eruption path or the abnormal position of the tooth germ. Impaction of mandibular second molar is relatively rare, and it may incite pathologic conditions such as dental caries, periodontitis, or root resorption of adjacent first molar. Thus, early diagnosis and treatment is recommended. In the first case, a 10-year-old male patient, was treated by brass wire to separate the bilaterally impacted mandibular second molars. In the second case, a 12-year-old female patient, was treated with Humphrey appliance for impacted mandibular left second molar, which was detected during a periodical dental examination. In the third case, a 17-year-old female patient with impacted mandibular right second molar, was treated by uprighting spring with mini-implant anchorage around premolar area. In the last case, an 18-year-old male patient, was treated with mini-implant placed on the ramus of mandible connected to the orthodontic buttons bonded on impacted mandibular left second molar by elastic thread.

Pierre Robin syndrome (PRS) is characterized by the triad of congenital mandibular hypoplasia, glossoptosis and cleft palate. Infant PRS patients are frequently suffering from upper airway obstruction, gastroesophageal reflux and growth retardation caused by above mentioned problems. We report a dental caries treatment of 3-year old girl with Pierre Robin syndrome with multiple caries. The cause of multiple caries was mainly presumed as patient's eating habit caused by her general condition. She had some feeding problems and had history of gastric tube. She was still using milk bottle and took more than an hour to finish a meal. The treatment was performed under general anesthesia considering patient's condition; mild autism, poor cooperation and respiratory problem due to micrognathia. Severely affected upper incisors were treated with pulp treatment and restored with zirconia crown for esthetic purpose. Lower incisors were treated with pulp treatment and restored with composite resin. Upper right first primary molar was restored with stainless steel crown and other primary molars were treated with composite resin. There were no postoperative complications. According to her parents, the patient's compliance to oral hygiene management was greatly improved after the treatment since she was very pleased with the esthetic result and highly motivated by her looks. The treatment without sedation or general anesthesia would be possible once the airway is improved as the mandible grows.
