The three child patients aged 3 to 5 years were worn by anterior space maintainer which are fixed type after missing of anterior teeth due to nursing caries, and were taken periodic follow check up. The results are : 1. At missing of anterior teeth, fixed space maintainer can be used. 2. Increased esthetic satisfaction and positive change of social behavior can be observed by these child patients. 3. Some phonations can be changed definitely after wearing the fixed space maintainer.

It is rare to find multiple supernumerary teeth in individuals with no other associated diseases or syndromes. 'Non-Syndrome multiple supernumerary teeth' reviewed by Yusof(1990) have more frequency of occurrence in the mandibular region. Especially, mandibular premolar region appears to be the site of predilection for no n-syndrome multiple supernumerary teeth. Also, these may develop after most permanent teeth have erupted, thus their effect upon the occlusion is limited. In this case, the patient had 20 supernumerary teeth without other associated diseases or syndromes. All of the supernumerary teeth were impacted, and thirteen of them were found in the premolar region. In the radiographic and clinical finding, other specific complication resulted from the supernumerary teeth weren't observed.

As one of the developmental disturbance in shape of teeth, a twinning has very rare frequency in permanent teeth. Because it is possible to diagnose the twinning by use of the radiograph, it is very important to detect this anomaly early by careful examining the radiographs. The twinning produces several orthodontic problem such as crowding, protrusion, ectopic eruption of adjacent teeth. Therefore it is necessary, in proper time, the extraction and orthodontic treatment should perform.

This study was to examine the developmental dental abnormalities in childhood cancer survivors. Risk factors were assessed for 125 children with radiographic data through a retrospective analysis of medical records and panoramic images. 68.0% of childhood cancer survivors exhibited at least one dental abnormality. The types of abnormalities varied depending on the age at cancer diagnosis and treatment intensity, ranging from microdontia (43.2%), to abnormal root development (39.2%) and tooth agenesis (33.6%). Logistic regression analysis demonstrated that a young age at diagnosis (under 3 years), the use of heavy metal agents, a history of hematopoietic stem cell transplantation (HSCT), and combination treatment of chemotherapy, radiation therapy, and HSCT were associated with a significantly higher risk for overall dental abnormalities. The increased risk ratios were 6.00, 3.06, 3.22, and 7.87, respectively (p < 0.05). The results of this study will predict dental abnormality in permanent dentition according to the diagnosis age and treatment method of childhood cancer.

Dens invaginatus is a developmental variation resulting from invasination of the tooth crown of root before calcification. Teeth most affected are maxillary lateral incisors. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. Root canal therapy may present severe problems because of the complex anatomy of the teeth. So, the early diagnosis of such malformation is crucial and a preventive approach has been recommended. This report describes three cases of dens invaginatus treatment.

Despite preventative efforts, aspiration and ingestion of foreign bodies during clinical dental procedures occasionally occur. Careful clinical and radiographic examination and prompt emergency management can prevent potentially serious consequences. In this report, we describe a case of accidental foreign body ingestion and discuss prevention and management of dental instrument aspiration and ingestion.

The purpose of this study is to establish the concept of the evidence-based pediatric dentistry and to investigate the application methods of it. The definition of the evidence-based pediatric dentistry was suggested as 'the integration of the best scientific research evidence with the professional expertise of pediatric dentist and the value of pediatric patients and their caregivers in dental practice for the child and adolescent'. The methods of practising evidence-based pediatric dentistry were investigated, the recent conclusions of the evidence-based pediatric dentistry were summarized by topics, the research methods of systemic review and clinical practice guidlines were analyzed, and the individual research methods as randomized controlled trials were investigated. The author proposed increasing the understanding and consensus of the necessity of evidence-based pediatric dentistry, education about the evidence-based pediatric dentistry, computerization of all published articles of Korean pediatrtic dentistry, continuing research and popularization of systemic research and clinical practice guidlines, production of Korea's own evidences of pediatric dentistry, and the improvement of soical environment of pediatric practice.

In the Pediatric Dentalc profession the occurrence rate intrusion of young permanent teeth is rather low, and the treatment method varies from one another. Intrusion of the teeth bring complications to the pulp and periodontal ligament, and thus the possibility of endodontic treatment increases. For the formation of calcific barriers, calcium hydroxide is used in young permanent teeth and this makes the final canal filling possible. In this case report, we will show two cases of young permanent teeth intrusion and the treatment methods to help assess the recognition of treatment for young permanent teeth intrusion.

Laser is getting more attention from increasing numbers of dental clinicians by its own several unique characteristics : precision, hemostasis, and bactericidal capacity. It also provides patients with several advantages of minimal tissue damage. faster healing with less postoperative pain and minimal use of local anesthetics. Labial or lingual frenectomies were performed successfully in three pediatric patients using Nd-YAG laser. When compared to the conventional scalpel method, less local anesthetics were needed and the bleeding control was so excellent that any suture was not necessary. The operation sites were completely healed without any infection or complication and discomfort from swelling or pain was not noted in all cases throughout the healing process.

This study describes the treatment of an immature permanent tooth with periapical lesion which was treated with regenerative approach using platelet rich plasma (PRP). The root canal of immature human permanent tooth with periapical lesion was gently debrided of necrotic tissue and disinfected with 2.5% NaOCl, and then medicated with triple antibiotic paste comprised of ciprofloxacin, metronidazole, and tetracycline. When the tooth was asymptomatic, PRP and mineral trioxide aggregate (MTA) were placed into the root canal. Six months after PRP treatment, radiographical examination revealed resolution of the radiolucency and progressive thickening of the root wall and apical closure. Our findings suggest that PRP can be used for the treatment of immature permanent teeth with periapical lesion, as part of a regenerative endodontic treatment procedure.
