The purpose of this study was to investigate parental knowledge and attitude and practices relating to infant oral health care and to promote their motivations to their children's oral health care. Authors interviewed 350 persons in Ilwon-Dong and whose children were between 0 to 36 months old and acquired questionnaire from them. The questionnaire constituted of questions about general knowledge of tooth eruption, methods of oral hygiene care, and opinions about preventive dental visit. The collected data were analysed and compared with other researches. The important results obtained from this study were : 1. Females and highly educated persons had more dental knowledge than males and poorly educated persons. But age and economic status did not affect their level of dental knowledge. 2. Fifty nine percents of respondents thought that tooth began to be formed before birth. 3. Seventy six percents of respondents thought that infant oral health care should begin before tooth eruption, but actually only 63% started oral hygiene care before age one. 4. Seventy percents of respondents used gauze for infant oral care. 5. Fifty seven percents of respondents still gave bottles to their children after they reached age one or more and 55% of respondents never heard of nursing caries. 6. Ninety percents of respondents agreed that carious deciduous teeth need restorations, and 31% of respondents thought that age two is the appropriate time for the first dental visit. 7. Forty seven percents of parents did not think that dental caries is an infectious disease. 8. Only Thirty three percents of parents visited dental clinics for examination and prevention during pregnancy and only 11% of expecting parents were offered dental health care education in pediatric or obstetrician clincs. 9. Information about oral health care was mostly given from baby megazines. 10. Overall parental knowledge about infant oral health care was not sufficient to maintain appropriate dental care for infants.

Regional odontodysplasia is a relatively rare condition in which both enamel and dentin are hypoplastic and hypocalcified. The result is localized arrest in tooth development. The etiology of regional odontodysplasia is uncertain, but, disturbance in vascular supply, somatic mutation, latent virus infection, trauma, hyperpyrexia, irradiation, nutrition, metabolic disorders and hereditary transmission are supported to be etiologic factors. Females are more often affected than males. (1.4 : 1). The maxillary arch is more often affected than the mandibular arch with the maxillary left quadrant being the most commonly involved. Affected teeth are hypoplastic, typically discolored yellow or yellowish brown, smaller in size and display a variety of surface marking including pitting and grooving. Radiographically, the teeth affected have been described to have a "ghost like" appearance or "fuzzy" appearance. Pulp calcification and denticles may be present within the pulp chambers of the affected teeth. In it's case, a 2 years old male visited for a treatment of uneruption of lower right teeth. Partial eruption of lower right deciduous central incisor and unerupted deciduous lateral incisor, deciduous canine and deciduous first molar showed severly delayed eruption state. On radiographic appearance, "Ghost like appearance", shortened root and opened apexes on lower right region were observed. It was suspected regional odontodysplasia with clinical and radiographic condition.

Since founded in 1959, it's well known that the KAPD has pioneered in the researches and clinical aspects of pediatric dentistry in Korea. It's official journal, the Journal of the KAPD, was first published in 1974 and has pressed total 956 articles up to now(March, 2001). In this study, all the articles pressed in this journal have been surveyed, focussing in their main theme, their chronological and thematic distribution. The thematic classification was made with the reference of the previous studies and renowned textbooks in pediatric dentistry. And we obtained the results as follows: 1. The researches on dental materials and dental equipments have shown continuous increase throughout the period. 2. The researches on dental caries, caries prevention and systemic disorders have occupied relatively high proportion consistently. 3. The researches on malocclusions and cysts/minor surgery have shown increasing tendency in the second period, but are decreasing in the third period. 4. The researches on craniofacial growth/development, tooth development/eruption, developmental disorders of teeth, management of eruption space have shown decreasing tendency. 5. The researches on behavioral research, oral habits, occlusion of primary-mixed dentition have shown very low proportion, reaching no more than 1% throughout the period.

The dentigerous cysts originate through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium, or between this epithelium and the tooth crown. Next to the radicular cyst, they are the second most common type of odontogenic cyst. They occur over a wide age range with a peak frequency in the 2nd to 3rd decade. A substantial majority involve the mandibular third molars, followed in order of frequency by the maxillary permanent canines, mandibular second premolars, and maxillary third molars. With regard to the treatment of these cysts, the marsupialization procedure with obturator is recommended during the age when the eruptive force of the teeth is still strong. It can be effective when preservation of the displaced teeth is desirable. We treated the dentigerous cyst by marsupialization with obturator and guided the eruption of involved teeth to normal position. And we got the results as follows : 1. Severely dislocated teeth associated with dentigerous cyst erupted into proper position. 2. The enamel hypoplasia and the root deformity were observed some cases. 3. The bone expansion and defect were healed without infection and recurrence.

Extracting mandibular incisors for orthodontic treatment may adversely affect the occlusion. However, when properly used, extraction of mandibular inciors is a selection for the correction of the malocclusion. Generally, treatment for crowding needs to select between nonextraction and four premolar extraction. Approaches for crowded mandibular incisors include distal movement of posterior teeth, lateral movement of canines, labial movement of incisors, interproximal enamel reduction, removal of premolars, removal of one or two incisors, and various combinations of the above. Extraction of incisors is used in case of crowding, anterior tooth size discrepancy, absent of maxillary lateral incisors, and ectopic eruption. But severe overjet. overbite, and space are the contraindication of it. A patient had severe crowding on upper anterior teeth, impacted upper left lateral incisor, palatal ectopic eruption of upper right incisor and severe crowding on lower anterior teeth. Lower lateral incisors are extracted for space availability and facial esthetics. We report the case of orthodontic treatment of upper and lower anterior crowding through extraction of lateral incisor.

Infraclusion may be defined as teeth that stop their relative occlusal movement in the dental arches during or after the period of active eruption and then remain under the occlusal plane. Delayed exfoliation, malocclusion, increased susceptibility to dental caries and periodontal disease of both the neighboring teeth and retained molar, and dislocation of the successor are the consequencces of infraclusion of primary molars. Therefore, early diagnosis and appropriate treatments are necessary. The therapeutic approach of the infracluded teeth varied from preservation to extraction. The teeth with simple infraclusion without any signs of interference with occlusal and jaw development may be examined periodically with follow-up check and radiographically. However, if the infracluded tooth interferes with normal eruption of successor or shows any sign of delayed resorption, or the tipping of adjacent teeth or supraeruption of opposing teeth is expected, the teeth inflicted should be extracted and appropriate measures should be provided in order to maintain the normal development of occlusion and dentition. The adjacent teeth which have been collapsed over a infracluded deciduous teeth can disturb the arch length perimeter. In such cases, surgical approach might be necessary, although it would be difficult when teeth are severly leaned. However, an easier surgical access have been obtained by space regaining procedures, in young patients whose arch length has been shortened due to the infracluded teeth.

Oculo-cerebro-renal syndrome, known as Lowe syndrome, is an X-linked gene disorder characterized by congenital cataracts, brain abnormalities and renal dysfunction. Tooth crowding, taurodontism, delayed eruption in the permanent dentition and over-retained primary teeth with ectopic eruption of the permanent teeth have been reported as dental findings. Because of the high incidence of poor cooperation, patients with Lowe syndrome have difficulties in maintaining good oral hygiene, which may require dental treatment. We present a case of dental treatment for the uncooperative child with Lowe syndrome under general anesthesia. A 4-year-old, 11.2 kg boy with Lowe syndrome visited Seoul National University Dental Hospital for gingival swelling. The patient had multiple caries requiring dental treatment. Because of his past history of malignant hyperthermia during inhalation induction, anesthesia was induced and maintained with total intravenous anesthesia (TIVA) after medical consultation. Dental restorative treatments were successfully performed and no complications were observed during and after the procedure. Safe and effective dental management of the patients with Lowe syndrome could be performed with the help of general anesthesia and careful monitoring.

The use of stainless steel crowns are indicated for restoration of primary or permanent molars with proximal dental caries, extensive dental caries, or previous pulp treatment with increased danger of tooth fracture. Stainless steel crowns were introduced by Humphrey in 1950. For their improved durability, longevity, and success rate, they have been strongly considered for restoring extensive and multi-surfaced dental caries of molars in pediatric dentistry. However, they also have shortcomings, such as possibility of pulpal exposure or damaging proximal surface of adjacent teeth. In addition, when oversized stainless steel crowns are used, eruption of the adjacent permanent teeth may be disturbed by their prominent margin. As a means to compensate the shortcomings of stainless steel crowns, use of orthodontics bands may be considered. It is an alternative restoration method, where an orthodontic band is placed on a tooth first and cavity is restored with filling material, such as composite resin, glass ionomer, or amalgam. The use of an orthodontic band is indicated for molar restoration with cervical dental caries, extensive dental caries, enamel hypoplasia, or previous pulp treatment. Because it requires shorter chair time compared to stainless steel crown, its application is very useful for children with poor behavior. However, restoration using an orthodontic band requires good oral hygiene after its application. This case report illustrates the conservative restoration of primary molars and permanent molars with extensive dental caries using orthodontic bands.

The first dental visit is recommended at the time of the eruption of the first tooth and no later than 12 months of age. However, even before the age of 1, children can visit the dental hospital for various reasons. The purpose of this study was to analyze the reasons for the dental visit of infant. From January 2006 to December 2015, medical records of infants who visited the Department of Pediatric Dentistry of Kyung Hee University were analyzed. The total number of patients was 419 (238 males and 181 females). The reasons for the dental visits were trauma (47.5%), natal/neonatal tooth (19.8%), dental caries (8.1%), teething problem (4.3%), abnormal frenum (3.6%), soft tissue swelling (3.6%), Bohn's nodule (3.3%), cleft lip and palate (2.9%), gingival neoplasm (1.9%), tongue ulceration (1.7%), oral examination (1.4%), enamel hypoplasia (1.2%) and abnormal temporomandibular joint sound (0.7%). According to this study, there were various oral diseases that could occur in infants. Since infants are usually cared by caregivers, pediatricians, and obstetricians, education of oral diseases of infants is needed to manage the oral symptoms properly.
Background and Objectives There was no clinical data except literary study on mutual correlation with autistic disorder in Western medical diagnosis and five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) in Oriental medical diagnosis. This study was performed to investigate the correlation of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) to the children with autistic disorder and to set the time table for clinical diagnosis of developmental retardation by making a comparative study of normal developmental children so we can treat the children with autistic disorder in good time. Method We made the comparative study of interview sheets recorded by parents of total 163 children who were diagnosed as autistic disorder who visited HaeMa Oriental Medical Clinic with interview sheets recorded by parents of generally accepted normal developmental children(263) and then we took statistics. Results : 1. There was significant correlation with speech and walking among five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) in autistic disorder statistically and clinically in comparison with normal children. 2. There wasn't significant correlation with growth time of tooth among five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) on diagnosis of autistic disorder in comparison with normal children. 3. There was significant correlation with retardation of times going to toilet by oneself (it does not consist in five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲).) in both of autistic disorder. Conclusion Autistic disorder was significantly correlated with the faculty of speech(語遲), retardation in walking out(行遲) of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲). We need to concrete the index of diagnosis, because it is so difficult to measure times and register retardation in tooth eruption(齒遲), retardation in hair-growing(髮遲), debility of neck and nape(頭項軟), flaccidity of extremities(手軟) and flaccidity of muscle(肌肉軟). And we can also use times going to toilet by oneself as one of diagnostic criteria because of its significant correlation. It is required to make early diagnosis of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) using these criteria, and to treat them early by oriental medicine.
