A Study on etiologic factors for tooth extraction and extraction age of patients visiting a university hospital dental clinic in suwon

Our study focused on etiologic factors for tooth extraction and extraction age for patients in medical clinics of suwon area. 3,357 teeth were selected for this study extracted between January,1,2010 to December,31,2012. The etiologic factors for teeth extraction retrospectively classified to KCD, and the results were as follows. 1. Periodontal diseases 37.5%, dental caries 29.0%, pericoronitis and impacted teeth 21.5%, radicular cyst 5.5%, fracture of teeth 3.4%, and the orthers 3.1%. 2. According to the age, pericononitis and impacted teeth was most prevalent before fifth decade and the most prevalent after that was periodontal diseases. Extraction caused by dental caries was commonly the second most prevalent in all age groups. 3. According to sex, extraction by periodontal diseases was prevalent in male(39.6%), and that by dental caries was prevalent in female(30.7%). 4. In comparison of upper and lower jaw, both jaws were prevailed by periodontal diseases. and the extraction by radicular cyst was prevalent in lower jaw(7.9%) in contracst to upper jaw(3.4%). 5. According to tooth type, all extracted teeth was caused by periodontal diseases except upper and lower 3rd molar. Among them, the most frequent tooth type was lower second molar(8.2%) and the least frequent tooth type was lower canine(2.2%). 6. Male was earlier(46.1years) than female(48.8years) in consideration of extraction age. The earlest extracted tooth was lower first molar(52.1years) and the latest extracted one was lower canine(68.1years) except wisdom teeth. Conclusively, typical causes of tooth extraction were periodontal diseases and dental caries. in which the former was prevalent in male, and the latter in female. All the teeth was extracted by periodontal diseases except wisdom teeth. Extraction caused by radicular cyst was more prevalent in lower than in upper.
