Abstract
|
|
|
Objectives: The object of this study was to determine the reasons for tooth extractions of permanent teeth in Korea.
Methods: 2009 National patient samples (NPS) data were obtained for patients from the Health Insurance Review and Assessment (HIRA). We conducted a frequency analysis of the reasons for 93,176 permanent teeth extraction.
Results: Overall, periodontal disease was the most frequent reason for tooth extraction (54.9%), followed by dental caries (38.4%). The males lost more teeth, due to periodontal disease than the females. In the below 30 age groups, caries was the main reason for tooth extraction. However, periodontal disease was remarkably increasing in those aged that were 30 year old and over.
Conclusions: Most of the permanent teeth are extracted, due to caries and periodontal disease. Furthermore, there has been no efficient way of prevention for periodontal disease in public health activities, which targeted the population of the middle age group. Such method might be required.
