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.

Chemotherapy or radiotherapy used for the treatment of pediatric cancer may have many adverse effects on the oral cavity. Oral mucositis, reduced salivary flow, oral infection, hypodontia, microdontia, arrested root development, and enamel hypoplasia are common oral complications. The aim of this study is to evaluate the effects of cancer therapy on dental caries activities. The children who had been treated for neuroblastoma in the department of pediatrics, Samsung Medical Center, were included and healthy children served as controls. The salivary flow rate, salivary buffering capacity, and Streptococcus mutans counts of both groups were evaluated using Dentocult$^{(R)}$ SM and Dentobuff$^{(R)}$ Strip. The dental caries activity related to the age at the start of treatment and the time elapsed since treatment completion were also evaluated. As a result, neuroblastoma patients had significantly lower salivary flow rate than the controls, while there were no significant differences between two groups as for salivary buffering capacity and Streptococcus mutans counts. The dental caries activities related to the age at the start of treatment and the time elapsed since treatment completion were not significantly different.

The purpose of this study was to analyze the traumatized primary teeth and investigate the occurrence, types, area, cause, place of trauma to primary teeth and seasonal variation in a hospital population, and to evaluate the interval between injury and treatment. A total 411 children with 745 traumatized teeth participated in this study from 1998 to 2000. The results were as follows : 1. There were slightly more boys than girls giving a male-to-girl ratio of 1.74:1.0. The 1-2, 2-3 year old boys and girls had the highest number of traumatic injuries to their primary dentition. 2. The most common injury was concussion. 3. The majority of traumatized teeth are the upper primary central incisors. 4. Falling down was the most common cause of injury in both sexes. The most of the injuries occurred inside home. 5. 46% of the children visited the dental office within 24 hours after traumatic injury. 6. The most common month was October(12.7%), and June(12.2%), May(11.7%) were followed.

Self-injurious behavior is often showed in mental retardation, especially in autism. Self-injurious behavior has been regarded as a symptom cluster rather than a disease but it is an emergent clinical situation that can directly affect mortality. This case is about a refractory autistic patient who showed a self-injurious behavior of hitting the head repetitively. He was hospitalized and was treated by pharmacotherapy and behavior therapy and for this reason this clinical experience is reported with literature review. The patient is a 7-year old boy who was ward admitted from 1999 April 20 till July 10 into OO hospital OO ward because of self-injurious behavior. During the 12 weeks he had admission treatment. As for the pharmacotherapy, haloperidol was dosed up from 0.5mg to 1.0mg from the 4th week and combination drug therapy was done during the admission with naltrexone 25-50mg. As for the behavioral therapy, Differential Reinforcement of Other behavior was used and regular play therapy was done. To remove the physical restraint, headgear and hard sleeve was used. Currently, OPD follow up treatment is being done and haloperidol 0.5mg and naltrexone 50mg is maintained. The patient’s mother is educated and play therapy is done an hour daily at home. When the patient was released form the hospital, self-injurious behavior was decreased more than the moderate state and remission state is still being maintained at the outpatient clinic.

The hemangioma, a benign proliferation of blood vessel, is the most common tumor of infancy and childhood. In many instances, the lesion probably represents a hamartoma or malformation rather than a true neoplasm. In the oral cavity, common sites are lips, followed by tongue, buccal mucosa and palate. Clinical characteristics appear as a flat or raised reddish-blue lesion and are generally solitary. They are classified on the basis of their histological appearance into capillary, mixed, cavernous or a sclerosing variety. A 6-year-old male of this case was referred to the Department of Pediatric Dentistry, Chonnam National University with a chief complaint of swelling lesion on gingiva. The strawberry appearance mass was detected by clinical examination on attached gingiva at the upper left primary lateral incisor and canine. Surgical excision and biopsy were carried out for histological examination and the lesion was diagnosed with a capillary hemangioma. The risk of recurrence after this therapy is rare, and there is no malignant transformation. Despite their benign origins and behaviour, hemangiomas in the region of oral cavity are always clinically important to the dental profession because of bleeding tendency.

Purpose: The aim of this study was to evaluate the clinical characteristics of children diagnosed as cryopyrin-associated periodic syndrome (CAPS) in Korea. Methods: Diagnosis was made based on clinical features and confirmed by a mutation in the cold-induced autoinflammatory syndrome 1 (CIAS1) gene. Especially, osteocartilaginous overgrowth in the patella or distal femur was so characteristic that its presence warranted a diagnosis of chronic infantile neurologic cutaneous and articular/NOMID. Results: We observed the clinical features of 9 Korean CAPS patients. All the patients suffered from an urticarial rash with recurrent fever. Among the 9 patients, 6 presented with rash and 4 with fever on the 1st or 2nd days of birth. Eight patients showed myalgia, and 7 patients showed arthralgia in the joints, and 6 patients showed radiologic findings of arthropathy including cupping of the metaphysis, excessive growth of the epiphysis, osteopenia or overgrowth of the cartilage. Four patients showed brain atrophy, enlarged ventricles or leptomeningeal enhancement on magnetic resonance imaging. Intellectual disability was observed in 1 patient. Five patients had eye involvement as conjunctivitis, uveitis, chorioretinitis, avascular area or papillary edema, and 3 patients showed progressive hearing loss. All 9 patients showed increased C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Conclusions: All the patients carried a mutation on exon 3 of the CIAS1 gene. After the anakinra (interleukin-1 receptor antagonist) therapy, the fever and rash immediately disappeared, and CRP and ESR were improved.

Objective: This study was conducted to comprehensively analyze domestic and international literature on the oral sensorimotor intervention approaches and evaluation/non-instrumental assessment methods for children with cerebral palsy with feeding disorders. Methods: One hundred and seventy-six papers published from January 2009 to December 2018 were screened. Forty-seven papers were selected based on the abstract and title, and five papers were selected through a secondary search. Results: The PEDro scale of the selected papers was high with an average of 7 points, and the therapeutic intervention period was found to be between 2 and 6 months, providing therapeutic interventions once to 5 times a week, at least 15 minutes to 1 hour a day. The treatment approach was used with impairment-based intervention and adaptive-based intervention, and the assessment method was divided into clinical evaluation and non-instrumental assessments. Conclusion: Through this systematic review, we found that there are a variety of oral sensorimotor interventions for children with cerebral palsy with feeding disorders. This study provides support for planning oral sensorimotor intervention programs for occupational therapy in clinical practice for children with cerebral palsy.

This study was aimed to evaluate orofacial morphologies on the cases of developmental disorders of maxillary first molars. Panoramic radiographs, lateral cephalographs, and clinical photos of 2983 children who attended the Pediatric Dental Clinic of Pusan National University Dental Hospital from 2006 to August 2017 were assessed retrospectively. 34 patients were selected whose maxillary first molars were missed or developmentally delayed unilaterally or bilaterally. Demirjian's method was used for estimating dental age, then which was compared to chronologic age of children. Parameters expressing skeletal and dentoalveolar disharmony were checked and compared with control. Additionally, occlusion relationship was evaluated. Maxillary dental age was significantly delayed compared to chronologic age. Several parameters which show skeletal open-bite tendency and skeletal class III malocclusion with maxillary retrusion were statistically significant. Anterior crossbite and edge-bite were expected in most of these cases, but compensation by occlusion and soft tissue was also verified which might mask skeletal class III tendency. Congenital missed or developmentally delayed maxillary first molars might be related with declined growth of maxilla. If developmental disorders of maxillary first molars were verified during clinical examination, careful monitoring of orofacial growth was necessary during puberty and timed orthopedic and orthodontic intervention were considered.

This study aimed to evaluate skeletodental characteristics of patient with maxillary lateral incisor agenesis (MLIA) in mixed dentition. It involved the children in early mixed dentition who visited Pusan National University dental hospital for orthodontic purposed and had intact primary canines. 38 children with MLIA and 38 controls with the same chronological age satisfying the inclusion criteria were selected. The craniofacial structures and dental arch dimensions of the MLIA were evaluated using model & cephalometric analysis and compared to controls. The rate of unilateral MLIA was high in male and the rate of bilateral MLIA was high in female. In model analysis, the width / length ratio of maxillary anterior portion of the MLIA group were higher and arch perimeter of the maxilla of the MLIA group were smaller than those of the control group (p = 0.003, 0.04). Cephalometric analysis showed that there were no significant differences in terms of skeletal, dental analysis. In soft tissue profile, nasolabial angle was larger in MLIAs than in controls (p = 0.039). Considering these skeletodental characteristics of MLIA, early diagnosis and proper management is highly recommended to minimize the possibility of functional defect.

Introduction : Oral motor function is basic function of sensory exploration, feeding, and communication, that develops from the fetal stage to childhood. Problems with oral motor function result in difficulty within handling food in the oral cavity, decreased swallowing and feeding skills, difficulty with communication, and problems with oral hygiene. To treat these symptoms, oral motor therapy is provided for normalizing sensory adaptation in the oral cavity, and increasing postural control, oral movement and oral motor function. Discussion : The oral motor facilitation technique (OMFT) was developed for increasing general and integrated oral motor function based on the following: 1) understanding orofacial muscular physiology; 2) a comprehensive approach to sensory·adaptation·behavior·cognition; 3) sensorimotor stimulation by a manual approach; 4) motor control and motor learning theory. The OMFT is a new evidence-based treatment protocol, for children and adults with neuromuscular and oral motor problems. Conclusion : The goal of this article is to provide a theoretical background for OMFT development and the basic concept for the clinical application of OMFT. We hope that this article will help oral motor therapy experts to provide effective therapy in a more professional way.
