A total of 580 patients, who visited and received an orthodontic diagnosis in the Department of Pediatric Dentistry, Seoul National University Dental Hospital from 2017 to 2019, were investigated in this study. The aim of this study was to evaluate skeletal patterns of pediatric orthodontic patients determined with lateral cephalometric analysis and to analyze the relationship between skeletal pattern and probable associated clinical features. Also, the modality of orthodontic treatment for each skeletal classification was investigated to aid in therapeutic decisions.<br/>Patients aged 7 year accounted for the largest age group; 54.2% of patients showed a skeletal class I pattern, 22.2% showed a skeletal class II pattern, and 23.6% showed a skeletal class III pattern. Bi-maxillary retrusion for skeletal class I, retruded mandible with normal positioning of the maxilla for skeletal class II, and retrusion of the maxilla with protrusion of the mandible for skeletal class III were the largest subgroups by skeletal pattern. Brachyfacial type accounted for 55.0% of patients, followed by 31.9% of mesofacial type and 13.1% of dolichofacial type. The prevalence of anterior crossbite in the study was 43.3%, higher than that in previous studies.

The aim of this study was to provide pathological information of pediatric oral lesions by retrospectively analyzing oral biopsy results from pediatric patients at the Seoul National University Dental Hospital. Biopsy results of all oral lesions from pediatric patients, aged 0 - 16 years, were collected from the files of the Department of Oral Pathology, Seoul National University Dental Hospital from January 2000 to April 2020. The patients were divided into 3 age groups: 0 - 5, 6 - 11 and 12 - 16 years. All oral lesions were classified into three main categories: inflammatory and reactive, tumor or tumor-like and cystic lesions. Among the total of 2928 biopsy specimens, tumor or tumor-like lesions(35.66%) were the most common, followed by inflammatory and reactive lesions(34.29%) and cystic lesions(30.05%). Regardless of the categories used in this study, odontoma was the most frequently found lesion, mucocele and dentigerous cyst being the next common. This study was the first retrospective review of pediatric oral pathology in Korea, and the results from this study may assist in providing informative insight into the pediatric oral pathology for pediatric dentists.

The purpose of this study was to analyze the effectiveness of newly developed dental dual-energy (DE) cone-beam computed tomography (CBCT) to compare both the voxel values in hard bone tissue of DE-CBCT and multidetector computed tomography (MDCT) images, collected in a clinical trial conducted at Seoul National University Dental Hospital. A software implemented as a scripted module of a three-dimensional (3D) slicer was developed to register the volume data from the MDCT space to DE-CBCT, locate the same 3D regions of interest (ROIs) in each image space, and extract the statistics of the ROIs. The mean values were paired and used as representative values of the ROIs. A scatter plot with the line of equality and Bland–Altman (BA) plot of difference for a pair of measured means were used for statistical analysis. Of the ROI pairs, 96% were within ±15% from the identity line, and more than 95% of the measured ROI pairs were within the limits of agreement of the 95% confidence intervals (CIs), with the CI of the limits in BA plots. The newly developed dental DE-CBCT showed a level of voxel value accuracy similar to that of MDCT.
