Methods: Prospective Descriptive study, all sectors of dental practice in northern Jordan were included in the sample, from the four northern governorates of Jordan. A questionnaire was distributed to randomly selected dentists and collected during first two weeks of June 2004. Results: Data were collected from 49 dentists, at the end of the study period 853 teeth were extracted from 512 patients. Caries was the most frequent cause for extraction (34.8%), followed by periodontal diseases (30.6%) and orthodontics (9.8%). In the age group under 50, dental caries was the main reason for extraction. However, in the age group over 50; periodontal diseases became the principal reason for extractions. Statistical analysis indicated that there was significant relationship between extractions due to periodontal diseases with tooth brushing also with occupation. Extractions due to orthodontic reasons were significantly related to females. Extractions for patients in various occupations showed important variations. Conclusions: Although no statistical relation was found between all causes of extraction and social factors but still there is a link between social and economical factors and different causes of extractions. KEYWORDS Extraction, Periodontal disease, Orthodontics, Socio-Demographic. INTRODUCTION There are different reasons for dental extractions which In Jordan, two studies were conducted by Haddad vary geographically and many studies to determine these and Ta’ani;6,7 Ta’ani found the peak of extraction was reasons (table 1) were conducted in different countries, between 31-40 years 72.3%, while Haddad found the including France, England and Wales, Scotland, Norway, peak was 41.8% between 21-30 years. Antigua, and Jordan.1-10 In Jordan, Haddad found that periodontal diseases were the major cause accounting Periodontal diseases appeared to be a leading cause for (33.4%) of extractions, followed by caries (27.6%),6 of dental extraction in elderly people.1-10 This is due while Ta’ani found that caries was the major cause to periodontitis, which is a chronic disease affected by accounting for 56.4% of all extractions.7 many causative and aggravating factors, which act throughout life.11,12 The studies which are shown in table 1 confirmed that extraction due to dental caries is significantly related Extraction for orthodontic reasons has been performed to age, but did not measure the effect of social and for decades in daily dental practice, these extractions are economical factors.1-10 However, in other studies tooth performed either to gain space or to prevent malocclusion.13 loss was found to be affected by social, economical, or other factors.
