| Abstract |
|
The purpose of this study was to investigate the principal reasons for primary teeth extractions and the tooth type extracted in children. 1159 patients were selected in this study. Dental records and radiographs were reviewed and age, gender, medical history, type of tooth extracted and the reasons for extraction were collected. The data were statistically analyzed using Chi-square test. Total 2078 primary teeth were extracted. Central incisors(34.1%) were most frequently extracted. Extractions due to physiological mobility(77.5%) were the most frequent followed by caries(13.8%), orthodontic(3.9%), trauma(1.7%). Reason for the extraction was different according to age (p = 0.000), but there was no difference according to gender (p = 0.109). While extractions due to physiological mobility predominated overall, reason for extraction was different according to the tooth type. There was no previous treatment in 54.6% of primary teeth extracted due to caries. Excluded physiological mobility, caries are the most common reason for extraction of primary teeth. The importance of preventive care should be emphasized in order to preserve primary teeth and improve children's oral health. |
