Muscular dystrophy (MD) is a heterogeneous group of inherited neuromuscular disorders, characterized by progressive muscle weakness. Severity of the disease ranges from mild to severe, and the disease is mostly caused by mutations in a number of genes. These genetic mutations cause lack of proteins which are essential for muscle cell stability. Muscle fibers are gradually replaced by fat and fibrous tissue. The muscles of the head and neck are affected in several types of MD that manifest as altered craniofacial morphology and dental malocclusion. A 3-year-10-month old, 15.0 kg boy with MD presented to Seoul National University Dental Hospital, Seoul, South Korea because of extensive carious teeth. A number of dental caries in primary dentition were identified during clinical oral examination. Due to dental anxiety and underlying systemic disease, general anesthesia was considered. General anesthesia was induced and maintained with intravenous anesthetics, propofol and remifentanil. Caries treatments - resin restoration, pulpectomy, zirconia crown restoration, stainless steel crown restoration - were performed. Under general anesthesia, successful dental procedure was done. Total intravenous anesthesia (TIVA) was performed instead of inhalation anesthesia in order to avoid risk of complications such as malignant hyperthermia and life-threatening rhabdomyolysis. With decreasing muscle function, plaque control becomes more difficult and leads to gingivitis. Especially, the open-mouth posture worsens gingivitis and can leads to malocclusions and problems in swallowing. Regular and periodic dental care is essential for maintaining oral health for patients with MD.

To achieve the dental health of children and adolescents which is the objective of the pediatric dentistry, the role of the public service should be increased. The basis of the public service is established by many laws of which the Dental Health Law is most important. The percentages of primary schools that had the school dental health clinic, that implemented the fluoride rinsing program, and that implemented the group toothbrushing after lunch were 7.2%, 57.5%, and 46.9%, respectively, and the percentages of primary school children that received the dental health education and that received the fissure sealing were 48.0% and 12.4%, respectively(2006). About 42% of infants and preschool children from 0 to 6 years received preventive dental care in the last one year, at the nursery or kindergarten(18%) or at the health center(1%)(2005). The percentage of the health centers that implemented water fluoridation was 11.3%, and the percentage of the population who drank the fluoridated water was 5.7%(2006). It was suggested that the school dental health administration should be unified, that dental health teachers should be employed, and that the comprehensive dental health care should be supplied to all the children and adolescents through the circuit school dentists and the school dental hospitals in the long term. Also, the dentist in charge system for the children and adolescent was suggested.

배경: 협조가 불가능하거나 진정법 하 치과치료가 여의치 않을 경우 전신마취 하 치료를 계획하게 된다. 하지만 전신마취 하 치료시 기관내 삽관이 여의치 않은 경우를 종종 경험하게 된다. 이와같은 경우 기관지경을 이용한 기관내 삽관을 시행한다. 기관지 내시경을 환자의 성문에 근접하게 전진시킬 경우 기관지 내시경 하 시야확보가 용이한 점을 감안 시 비공 - 성대간 거리를 예측하는 것은 매우 유용할 것으로 생각된다. 또한 비공 - 성대간 거리를 추정하게 되면 맹목적 비강내 기관내 삽관을 하는데도 도움이 된다. 방법: 본 연구는 전신마취하 치과치료가 예정되어 있는 62명의 소아환자들을 대상으로 하여 신체변수와 비공 - 성대거리와의 관계를 확인해보고자 하였다. 선형회귀분석을 시행하여 다음과 같은 결론을 도출하였다. 결과: 소아환자들에 있어 비공 - 성대간 거리는 환아의 신장, 체중, 연령 등과 상관관계를 나타내었다. 비공 - 성대간 거리와 상관관계를 보인 변수들 중 에서 신장과의 상관계수가 가장 높았다. 선형회귀분석을 통해 비공 - 성대간 거리를 예측하는 다음과 같은 회귀식을 구하였다. 비공 - 성대간 거리 = (4.8 + 신장(cm)) ${\times}$ 0.07 고찰: 본 연구에서 구해진 회귀식을 이용하여 기도유지가 어려운 소아의 기도유지 하는데 큰 도움이 될 것으로 생각된다.

Prader-Willi Syndrome (PWS) is a rare neurologic disorder with a prevalence 1/10,000-30,000. The cause of PWS is an abnormalities of chromosome 15q11.2-q13 which is an imprinting gene. Obesity and hyperphagia are characteristic features on a PWS adult. On the other hand, the birth weight, height and body mass index (BMI) of PWS infants are 15-20% lower than those of normal babies and there is a failure to thrive until 24-month-old. Most of PWS patients are treated under general anesthesia and conscious sedation. This case is a treatment of severe caries in a PWS 46 month-old child without general anesthesia and conscious sedation. He came to the Department of Pediatric Dentistry, Kyung Hee University Dental Hospital at Gangdong, Seoul, Korea with a trauma history. He had a medical history with heart surgery and needed to take antibiotics prophylaxis. The luxated left upper primary tooth were removed and caries treatment were done as an outpatient without general anesthesia, conscious sedation.

Objectives : The purpose of this study was to examine relationships between bone age and body composition to make efficient clinical reviews on children's growth. Methods : 157 of children in age of 3 years to 16 years old were participated in this study(88 of boys and 69 of girls). They visited the department of pediatrics, OO university oriental hospital and were measured their body composition and bone age. Results : 1. An age and bone age, height, weight, and body mass index were positively correlated, and also a bone age and height, weight, and body mass index were positively correlated. 2. The level of soft lean mass, body fat mass, and MPH were increased in boys in higher height percentile. Children's predicted adult height was higher in children in higher height percentile. 3. The level of body fat mass was increased as weight percentile increased. Bone age, MPH was increased as weight percentile increased, especially in case of boys. In girl's case, the level of soft lean mass, their predicted adult height, the difference between children's bone age and their actual age was increased as weight percentile increased. Conclusions : Measuring bone age and body composition is the effective way to estimate children's growth and development in future.

Purpose : This study was to examine the relations of perception of physique with self-esteem, sociality and problematic behaviors in children. Methods: Four hundred sixty five (231 boys and 234 girls) children were divided into three groups according to their height or body mass index according to the physical growth standard table had been presented in 2007 by the Korean Pediatric Society. The group 1, 2, and 3 was short, borderline and normal or obese, overweight and normal, respectively. Their perception and satisfaction of height and weight were investigated, and their self esteem and behavior styles were examined with Self-Esteem Inventory (SEI) and Korean Child Behavior Checklist (K-CBCL). We compared the numbers of appropriate perception, satisfaction, self-esteem and problematic behaviors in each group, and analyzed the relationship among perception of physique, self-esteem, sociality, and behavioral characteristics. The collected data were analyzed with chi-square test, ANOVA and Pearson correlation coefficient used with SPSS (ver. 12.0). Results : There were significant mismatches among their real physique perception and satisfaction (P<0.05). There were no significant differences of their self-esteem, sociality, and problematic behaviors according to their actual height and weight. There were significant differences of their self-esteem according to their perception or satisfaction of their height and weight (P<0.01). Conclusion : The children who considered themselves have short stature or obesity had problematic behaviors or low self-esteem. Therefore, children should be educated to have the appropriate perception of their own body image.

The purpose of the present study was to investigate the relationship between obesity and dental caries in children and adolescents. This study was analyzed by searching the following words in Google Scholar (https://scholar.google.co.kr), Kiss (kiss.kstudy.com), KCI (www.kci.go.kr), and RISS (riss.kr): "pediatric," "juvenile," "obesity," and "dental caries." A total of 19 Korean and 10 foreign studies out of 107 studies were selected after excluding the studies based on the exclusion criteria. When evaluating the relationship between childhood and adolescent obesity and dental caries, 16 out of 29 articles (55.2%) indicated a significant relationship, and 2 (6.9%) indicated different results based on sex, while 13 articles (44.8%) showed no significant relationship between obesity and dental caries. Among the significant studies, a total of 10 (34.5%) showed that the number of dental caries increased according to an increase in obesity, i.e., from normal to overweight to obese. A total of 5 studies (17.2%) reported that the number of dental caries increased in underweight individuals compared to those of normal weight, or decreased according to an increase in obesity, while 1 study (3.4%) indicated that the number of dental caries increased in both the underweight and obese groups compared to the normal weight group. Therefore, studies on the relationship between dental caries and the degree of obesity in children and adolescents have not shown a certain trend.

Recently, the use an electric apparatus has brought into concerns about health risks from exposure to electromagnetic fields. During the last 2 decades, a number of epidemiological studies have explored the association between childhood leukaemia and residential exposure to power-frequency electromagnetic fields. Several studies have suggested that there is a small excess leukaemia risk with magnetic field exposure above 2 mG. A number of governmental and international organizations have developed exposure gudelines. The most rigid regulation with exposure levels for the elementary school and hospital has been enacted by Switzerland. Although there is no convincing supportive laboratory evidence, and the absence of a plausible biological mechanism of disease causation limits, governments are increasingly called on to adopt precautionary approaches to regulating electromagnetic field exposures. The government would need to establish the policy for electromagnetic fields and continually to be concerned about possible health risks from exposure to electromagnetic fields.

Dentinogenesis imperfecta is a hereditary disorder that causes abnormal dentin formation and tooth morphology. Affected teeth show very thin dentin and large pulp chamber. Immediately after their eruption, the teeth tend to be destroyed rapidly. Early dental intervention is recommended to improve the feeding capacity and quality of life for the child, to maintain vertical dimension, and to promote healthy and functional dentition. This case report describes a treatment for a 4-year-2-month-old girl whose primary and permanent dentition were affected by Dentinogenesis Imperfecta. Shell teeth were observed in the entire primary dentition. The pulp of most teeth was exposed and the patient complained of pain. Most paternal family members were transferred to the Dentinogenesis Imperfecta. She needed an extensive dental treatment, but her compliance could not be expected because she was very young and anxious. So we decided to treat her under general anesthesia. All molar teeth are restored with Stainless Steel crown. Maxillary anterior teeth were extracted and mandibular anterior teeth are restored with composite resin. The patient's pain disappeared and masticatory function was restored.
