LUCAVECHI-ALCAYAGA, Tania; SUAREZ-CLUA, Mª Cruz  e  BARBERIA-LEACHE, Elena. Study of prevalence and causes of tooth extractions in a Spanish infant population. RCOE [online]. 2004, vol.9, n.1, pp.65-72. ISSN 1138-123X.

Introduction. There are many studies available examining the reasons for tooth extractions in adults, but little information exists on extractions in infant populations. This study examines the frequency and distribution of tooth extractions and the reasons for them in a specific sample. Materials and methods. Files of patients from 0-15 years of age were studied regarding to age, gender, the extracted tooth or teeth and the reason for the extraction. Results. Of the 1,062 files studied, 40.5% had a history of extractions. Of the total number of extractions performed, 89.5% were related to temporary teeth and 10.5%, to permanent teeth. The age range in which the largest number of extractions were performed was between 6 and 9 years of age (45.91%). The most frequent motive was for orthodontic reasons (44.75%). The upper first temporary molars were the most frequently extracted teeth. Conclusion. Orthodontic reasons and caries are the most frequent causes for recommending extractions in this population. The central incisors and the first and second molars are the most frequently extracted teeth, with considerable differences between the different age groups.
