The aim of this study was to analyze the dental caries of chilren's deciduous teeth in relation to their mothers' socioeconomic factors and their oral health beliefs to increase the effect on children's oral health. One hundred seventy four children and their mothers were selected for the study. The children were 5 and 6 years old in children house in Kun-san, Korea. Research was conducted by oral examination, their mothers' socioeconomic factors and dental health belief model. The finding of analysis can be summaried as follows; In regard to the caries in deciduous teeth status, the five-year-old boy children's dft index was 3.39 and that of the girls of the same age was 2.76. The dft index of the boys of six was 3.86 and that of the girls of the same age was 3.27. The five-year-old boy children had the highest df rate(81.8%), and their dt rate was more than their ft rate. But for the six-year-old girl children, ft rate was higher than dt rate. For the five years old, the boy children's ft rate was significantly higher than that of the girls(p<0.05). Concerning the caries in deciduous teeth states by socioeconomic factors, their oral health status was significantly different according to mother employment and householder age. The df rate of the preschoolers with working mothers(84.7%) was significantly higher than that of those with nonworking mothers(66.7%)(p<0.05). The dft index of the group whose households were over forty was highest with 4.07, followed by the children of the households aged 35 to 39 with 3.83, those of the households aged 25 to 29 with 3.33, and those of the households aged 30 to 34 with 2.15. The difference between the groups was significant(p<0.05). As to the difference of maternal dental health beliefs by maternal socioeconomic factors, households educational background and whether to live with parents or parents-in-law under the same roof made a significant difference to maternal oral health beliefs. The mothers whose households were college graduates or better-educated were stronger in oral health susceptibility and seriousness(p<0.01, p<0.05). The salience was recognized more by those who lived with parents or parents-in-law than by the others who didn't(p<0.05). The dft index of the preschoolers was related to maternal dental health beliefs. That was lower when their mothers perceived dental health benefit better.

Moyamoya disease is a disorder in which certain arteries in the brain are constricted. Blood flow can be blocked by the constriction and blood clots. The patients frequently experience transient ischemic attacks (TIA), cerebral hemorrhage, or may not experience any symptoms at all. It is reported that they have a higher risk of recurrent stroke and a distinct underlying pathophysiology. A 3-year-8-month old boy with moyamoya disease experienced cerebral infarctions five times, and he underwent a cerebrovascular anastomosis surgery four years ago. He showed swallow disturbance, general delayed development, hemiplegia, and strabismus. Also he had hypocalcified teeth with or without multiple caries lesions in all dentitions. Dental treatment under general anesthesia using sevoflurane was performed due to his lack of cooperation. Moyamoya disease is associated with various medical conditions requiring a thoughtful deliberation and a careful examination before and during dental treatment. Pain and anxiety control during dental treatment is important because hyperventilation induced by crying has been seen to trigger TIA. Both isoflurane and sevoflurane are commonly used in patients with MMD, but dynamic autoregulation is better preserved during sevoflurane than isoflurane anesthesia. So sevoflurance general anesthesia may be recommendable to manage dental patients having multiple caries with moyamoya disease.

Hydrocephalus is characterized by accumulation of cerebrospinal fluid in the ventricles of the brain causing progressive ventricular dilatation. Accumulation of cerebrospinal fluid typically causes increased pressure inside the skull, this may result in headaches, vomiting, nausea, seizures, sleepiness and mental impairment. Patients with hydrocephalus may have dental manifestations such as changes in the occlusion and greater accumulation of plaque. The prevalence of dental caries is high due to the difficulty of oral care. The purpose of this case report is to describe the dental care for an uncooperative child with hydrocephalus under general anesthesia.

Glanzmann's thrombasthenia (GT) is a rare, autosomal recessive inherited congenital disorder, characterized by impaired blood coagulation due to platelet dysfunction. It was first reported by the pediatrician Glanzmann in 1918. GT affects both males and females, and it is more common in regions of the Middle East, India, and France, where intermarriage is common. It has an incidence of about 1 in 1,000,000 people. In South Korea, according to the Division of Rare Diseases, Korea Centers for Disease Control and Prevention, around 200 cases have been reported in 2018. Clinical symptoms include petechia, ecchymosis, epistaxis, and gingival bleeding. The spontaneous loss of deciduous teeth can result in excessive bleeding with that blood transfusion should be considered. Preventing hemorrhages and hemostasis are most important factors in dental treatment. Local bleeding can be controlled by compression, but platelet transfusion can be required by prolonged bleeding. Pediatric dentists can minimize the gingival bleeding by control of the oral hygiene to prevent gingivitis and dental caries. The importance of oral hygiene and periodic recall check-up should be emphasized. During dental treatment, the examination and the treatment plan of patient should be modified to prevention of hemorrhages carefully. A 6-year-old girl with GT was referred for the treatment of dental caries, and resin restoration was performed under nitrous oxide inhalation sedation. After treatment, compression was required for the bleeding control.

Due to increasing demand for aesthetics, zirconia crowns have become a popular choice for treating primary molars. However, there is limited literature available comparing the survival rates of zirconia crowns with those of other restorative materials. The objective of this study was to compare the 36-month survival rates of zirconia crowns and stainless steel crowns for proximal caries, as well as to analyze failure types associated with each crown type. Electronic medical records and radiographs of 1,061 primary molars from 498 patients treated with 2 types of prefabricated crowns at Chosun University Dental Hospital and 2 private dental clinics between 2017 and 2019 were collected and analyzed. The survival rate of zirconia crowns was found to be lower compared to that of stainless steel crowns. Regarding the groups without pulp treatment, the survival rate of stainless steel crowns was significantly higher than that of zirconia crowns. However, in the groups that received pulp therapy, no significant difference in the survival rates was observed between the two preformed crowns. Notably, abnormal root resorption or periapical lesions were identified as the primary cause of restorative failure in stainless steel crowns, whereas loss of restoration was the predominant cause in zirconia crowns. This study holds valuable implications for clinicians when selecting preformed crowns for primary molars.

An infraoccluded tooth is a tooth that has failed to erupt to be in line with adjacent teeth in the vertical plane of occlusion. Multiple complications can occur as a result of an infraoccluded tooth. Tipping of neighboring teeth, loss of space opposing teeth elongation, increased susceptibility to dental caries and abnormal eruption path, impaction and rotation of permanent successor are the consequences of infraocclusion of primary molar. Therefore, early diagnosis and treatment is the key to prevent the complications. Treatment options can be periodic follow-up, temporary restoration or extraction of the infraoccluded tooth depending on the presence of the successor, the extent of infraocclusion and the extent of tilting of the neighboring teeth. The infraoccluded primary molars with permanent successors present tend to exfoliate normally. However, failure to do periodic check up of the infraoccluded teeth may lead to serious complications. In these cases, surgical extractions are often necessary after space regaining and space maintainers should be placed until the eruption of the permanent successors are completed.

Talon cusp is cusp-like structure that develops additionally in crown of anterior tooth. And it is one of dental anomalies. Talon cusp can cause various diagnostic, functional, aesthetic problems depending on the size and configuration of cusp. there is a tendency for caries to occur in the developmental grooves, and advanced attrition, periodontal problems, irritation the tongue and temporomandibular pain, occlusal interference and displacement of affected tooth may result. Therefore, early diagnosis and appropriate treatment of each case is important so that it minimize local problems, such as caries, periodontal diseases, and malocclusion. These cases which are in permanent and primary anterior teeth are about gradual reduction forming reparative dentine and complete reduction of talon cusp and root canal therapy which is an alternative and effective form of treatment when gradual reduction of talon cusp may not be possible.

The purpose of this study is to evaluate the intravenous (IV) sedation technique with midazolam and ketamine for uncooperative dental child patients. Three child patients between the ages of 4.4 years and 5.6 years who required sedation for dental treatment were given midazolam and ketamine. Initial dosage was combined of $0.03{\sim}0.06mg/kg$ midazolam and 1.0mg/kg ketamine. Additional dosages of ketamine (0.33mg/kg) were given as needed to maintain deep sedation. Pulse rate, respiratory rate, blood pressure, oxygen saturation, adverse reactions, postoperative recovery and behavior were monitored with saturation pulse oximetry, ECG, NIBP and Cardiocap. In conclusion, the combination of midazolam and ketamine is efficacious in deep sedation for painful dental treatment. However, a significant drop in oxygen saturation was observed as a common adverse side effect. Therefore advanced airway management proficiency is required in order to achieve a successful IV sedation.

Shortened dental arch (SDA) as a treatment goal is the concept that stable occlusion and enough masticatory force can be achieved by restoration to the second premolars when the situation is not favorable. SDA could be applied both natural teeth and implant supported fixed prostheses. This case dealt with a patient who has grade 2 intellectual disability and a lot of missing teeth. Because of intellectual disability, patient cooperation during treatment could not be expected. Therefore every treatment should be done under general anesthesia. In addition to that, ridge resorption around molar area was severe and there were maxillary sinus pneumatization and maxillary sinusitis which increased failure probability. SDA concept was adopted to reduce risk factor and minimize general anesthesia. After the treatment, functional and esthetic improvement was achieved and oral hygiene was fortified by periodic recall check and education.
