Interest in orthodontic treatment has increased. Consequently, the percentage of the orthodontic treatment in pediatric dentistry has also increased. Given this background, the purpose of this study was to analyze the characteristics and the trends of pediatric orthodontic patients of Chonnam National University Dental hospital. A total of 670 patients (349 male, 321 female) diagnosed with orthodontic problems during the period from January 1st, 2004 to December 31st, 2014, were analyzed. The number of pediatric orthodontic patients was high in January, February, July and August. When it comes to age, the percentage of the patients who were eighty-years old accounted for the largest age group with 19.6%, followed by seven-year, nine-year, ten-year, eleven-year, and six-year old age groups. Skeletal class 1 accounted for 48.1% of the total cases, followed by class 2 (28.7%) and class 3 (23.3%). Mesofacial type accounted for 65% of the total cases, followed by dolichofacial type (19.3%) and brachyfacial type (15.8%). The period of the first phase orthodontic treatment was steadily shortened from 30.4 months in 2004 to 11.5 months in 2013. The result of this study is expected to provide information of the pediatric orthodontic patients.
