The dentists often encouter a child who can not be treated with traditional behavior management technique. Mentally or physically handicapped child could receive proper dental care under general anesthesia. General anesthesia for dental care can be done in an outpatient surgery or inpatient surgery depending on the patient. In outpatient surgery, the patient is admitted and discharged the same day. Postoperative care and discharge procedure are abbreviated. Advantages of outpatient surgery are much less emotional disturbance of patients, reduced risk of nosocomial infection and less cost of treatment. A case of a physically handicapped patient treated under general anesthesia at Day Surgery Center is presented and the procedure and patient selection of outpatient surgery as well as its limitation is reviewed in this paper.

Plasma Arc Curing(PAC) units operate at relatively high intensity and claimed to result in optimum properties of composite resin in a short curing time, so the interest of pediatric dentists about PAC units have been increased recently. But PAC units used for polymerizing restorative resins produce heat during operation. The purpose of this study was to evaluate temperature transmission through dentin of various depths using two types of PAC units(Flipo, Q-Lux plasma 100). The results from the present study can be summarized as follows : 1. When PAC be used continuously, temperature on tip was increased as curing times, and Q-Lux showed greater temperature rising(p<0.001). 2. Compared temperature transmission as dentin depth, temperature rising rate was decreased as dentin thickened(0.5, 1.0, 1.5, 2.0mm)(p<0.05). 3. Compared temperature transmission as resin depth, temperature rising rate was also decreased as resin thickened(1.0, 2.0mm)(p<0.05).

Objective: The study aimed to assess the prevalence of dental malocclusion, orthodontic parameters, and parafunctional habits in children with developmental dyslexia (DD). Methods: Forty pediatric patients (67.5% boys and 32.5% girls, mean age: 11.02 ± 2.53 years, range: 6-15 years) with DD were compared with 40 age- and sex-matched healthy participants for prevalence of dental malocclusion, orthodontic parameters, and parafunctional habits. Dental examinations were performed by an orthodontist. Results: Pediatric patients with DD exhibited a significantly higher prevalence of Angle Class III malocclusion (22.5% vs. 5.0%, P = 0.024), deep bite (27.5% vs. 7.5%, P = 0.019), midline deviation (55.0% vs. 7.5%, P < 0.0001), midline diastemas (32.5% vs. 7.5%, P = 0.010), wear facets (92.5% vs. 15.0%, P < 0.0001), self-reported nocturnal teeth grinding (82.5% vs. 7.5%, P < 0.0001), nail biting (35.0% vs. 0.0%, P < 0.0001), and atypical swallowing (85.0% vs. 17.5%, P < 0.0001) compared to that in healthy controls. Conclusions: Pediatric patients with DD showed a higher prevalence of Class III malocclusion, greater orthodontic vertical and transverse discrepancies, and incidence of parafunctional activities. Clinicians and dentists should be aware of the vulnerability of children with dyslexia for exhibiting malocclusion and encourage early assessment and multidisciplinary intervention.

Background: Dentists make various efforts to reduce patients' anxiety and fear associated with dental treatment. Dental sedation is an advanced method that dentists can perform to reduce patients' anxiety and fear and provide effective dental treatment. However, dental sedation is different from general dental treatment and requires separate learning, and if done incorrectly, can lead to serious complications. Therefore, sedation is performed by a limited number of dentists who have received specific training. This study aimed to investigate the proportion of dentists who practice sedation and the main sedatives they use in the context of the Republic of Korea. Methods: We used the customized health information data provided by the Korean National Health Insurance. We investigated the number of dental hospitals or clinics that claimed insurance for eight main sedatives commonly used in dental sedation from January, 2007 to September, 2019 at the Health Insurance Review and Assessment Service. We also identified the changes in the number of dental medical institutions by region and year and analyzed the number and proportion of dental medical institutions prescribing each sedative. Results: In 2007, 302 dental hospitals prescribed sedatives, and the number increased to 613 in 2019. In 2007, approximately 2.18% of the total 13,796 dental institutions prescribed sedatives, increasing to 3.31% in 2019. In 2007, 168 institutions (55.6%) prescribed N₂O alone, and in 2019, 510 institutions (83.1%) made claims for it. In 2007, 76 (25.1%) hospitals made claims for chloral hydrate, but the number gradually decreased, with only 29 hospitals (4.7%) prescribing it in 2019. Hospitals that prescribed a combination of N₂O, chloral hydrate, and hydroxyzine increased from 27 (8.9%) in 2007 to 51 (9%) in 2017 but decreased to 38 (6.1%) in 2019. The use of a combination of N₂O and midazolam increased from 20 hospitals (6.6%) in 2007 to 51 hospitals (8.3%) in 2019. Conclusion: While there is a critical limitation to the investigation of dental hospitals performing sedation using insurance claims data, namely exclusion of dental clinics providing non-insured treatments, we found that in 2019, approximately 3.31% of the dental clinics were practicing sedation and that N₂O was the most commonly prescribed sedative.

The incidence of childhood cancer is greatest in the first year of life. Early diagnosis and advances in medicine have significantly improved outcomes of treatment resulting in higher survival rate; however, this progress comes at the expense of a higher incidence of adverse side effects because of more aggressive antineoplastic treatment strategies. The oral cavity, a trauma-prone environment, is extremely sensitive to toxicities from antineoplastic agents. Oral health care specialists, including pediatric and hospital dentists can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment, and assisting and/or managing oral complications from cancer therapy. This article covers the considerations in the dental management of pediatric patients undergoing cancer treatment, specifically chemotherapy, radiotherapy, and hematopoietic stem cell transplantation.

The purpose of this survey was to investigate parental recognition and preference on pediatric dentist and their behavior management technique. The subjects were the parents of new children visiting the Department of Pediatric Dentistry, Pusan National University Hospital for 6 months. The questionnaire was performed over 2 times : at 1st visit and 1 month after that. The parental preference about pediatric dentist - one's sex, color of gown and glass-wearing - and about behavior management technique - parental separation, oral sedation, voice control and physical restraints-were asked through the questionaire and obtained the results were as fellows: 1. The preference on sex of dentists was not shown. 2. The parents recognized not so close relation between glass-wearing and children's anxiety level, but on color of gown, showed various opinions. 3. Most parents opposed to the separation from their children in operatory. 4. For the behavior management technique, parents accepted generally. 5. There was no significant difference between the first and second survey.

Achondroplasia is one of the most common types of dwarfism and is inherited as an autosomal dominant trait. Clinical features of achondroplasia include disproportionate short stature with normal trunk length, shortening of the extremities, bowing of the lower extremities, short stubby trident hands, spinal stenosis and lumbar lordosis. Characteristic craniofacial features include macrocephaly, prominent forehead, depressed nasal bridge, maxillary hypoplasia, otolaryngeal system dysfunction, and foramen magnum stenosis. These characteristics may lead to number of complications including hydrocephalus, apnea, upper-airway obstruction, otitis media, sinusitis and dental malocclusion. Apart from these features, the affected children have good general health and normal intelligence. Dentists should be aware of the clinical characteristics of achondroplasia and the complications that may arise as a result of this disorder. This case report is to present dental treatment of a patient with achondroplasia under general anesthesia and discuss special considerations.

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.

Pediatric dentists often meet children with abnormal in number of tooth. Presence of supernumerary teeth is frequent cause of malocclusion. Etiology for supernumerary teeth is not yet clearly defined, but it is thought to be caused by excessive proliferation of dental lamina by hereditary and environmental factors. Supernumerary teeth occur in the maxilla nine times more frequently than in the mandible. Most common supernumerary tooth is the mesiodens in the maxilla, and some are observed in the maxillary molar and mandibular premolar. It occurs rarely in the mandibular incisor region with the incidence of 1-2% among all supernumerary teeth. A six-year old boy visited the department of the pediatric dentistry, Yonsei University Dental Hospital, with the chief complaint of crowded supernumerary teeth on the mandibular incisor region. Clinical and radiographic examinations revealed six permanent mandibular incisors similar in size, shape, and length. Further investigation using computed tomography(CT) was proceeded on the mandible to measure and compare morphologic features and positions of the six incisors. Then, we decided to remove two incisors which were already erupted. Periodic check-up was followed to monitor the dental development and spontaneous positional enhancement of the remaining four incisors in the mandible.

The purpose of this study was to evaluate the ability of Q-ray view (All-in-one Bio, Seoul, Korea) in detection of proximal caries in primary molars with sound marginal ridges. Thirty two children aged 3-9 years (average $5.6{\pm}1.3$ years old) were chosen, and two examiners evaluated 100 proximal surfaces of primary molars with sound marginal ridges. The teeth were examined with; (a) visual examination, (b) Q-ray view, (c) DIAGNOdent (KaVo, Biberach, Germany) and (d) digital periapical radiography. Kappa statistic was used to assess the agreement between each examination method and the degree of caries progression. The kappa values for enamel caries were 0.15 (visual examination), 0.10 (Q-ray view), 0.25 (DIAGNOdent) and 0.68 (digital periapical radiography). The kappa values for dentinal caries were 0.34 (visual examination), 0.56 (Q-ray view), 0.44 (DIAGNOdent) and 0.70 (digital periapical radiography). Although Q-ray view showed low diagnostic ability in detection of enamel caries, it was effective in detection of hidden proximal caries extended into dentin. Q-ray view would be a useful and simple device which could aid pediatric dentists in detection of hidden proximal caries in primary molars especially when examining uncooperative children or disabled persons.
