The aim of this study was to examine the reasons for dental extraction and to determine the pattern of tooth loss in patients seeking care at the oral surgery teaching clinics in the Faculty of Dentistry of the University of Jordan, Amman, Jordan, over a 3-year period. Data pertaining to the dental extractions of 2435 patients were analyzed. The results showed that 63.8% of the teeth included in this study were extracted because of dental caries, 22.9% because of periodontal disease, and 11.0% for prosthetic reasons. Pericoronitis, orthodontic treatment, trauma, and eruption problems accounted for 2.4% of the reported extractions. The upper premolars were the teeth most commonly extracted, and the lower first and second molars were the teeth most commonly extracted because of dental caries. The logistic regression test revealed that extraction because of dental caries occurred mostly in the group aged 21 to 30 years (P<.001). Periodontal disease was not likely the cause of extraction in patients younger than 40 years. Mandibular incisors were the teeth least likely extracted because of dental caries (P<.001), but they were the teeth most commonly extracted because of periodontal disease (P<.001). Extraction for orthodontic reasons mostly involved the premolars (P<.05) and occurred in patients 20 years of age or younger (P<.001). Men were less likely to lose teeth because of caries and periodontal disease (P<.05 and P<.001, respectively) and were more likely to lose teeth for prosthetic reasons and trauma. The information gained from this study is useful to shift oral health planning toward emphasizing the importance of maintaining natural dentition and preventing dental disease.
