Purpose: In the present study, we present clinical and radiological grounds as well as principles of tooth extraction based on tooth extraction cases in the Department of Periodontology at Wonkwang University Dental Hospital. Materials and Methods: This study was conducted on 323 patients who visited the Department of Periodontology at Wonkwang University Dental Hospital and underwent tooth extraction. Their medical records and radiographs were surveyed, along with smoking habits, systemic diseases, medication/tooth mobility, and probing depth. Crossover analysis was performed to examine the interrelationship between smoking and its causes. Results: A total of 620 teeth was extracted. The proportion of smokers in patients who underwent tooth extraction due to periodontal problems was higher. However, there was no statistically significant difference (p>0.05) between periodontal problems and other problems. A total of 383 (61.77%) showed periodontal problems: “floating state” or loss of attachment in entire roots (radiolucent images with average width of about 2.65 mm surrounding roots), which was a typical example of extraction with periodontal problems (193, 50.39%). A total of 106 (17.10%) showed prosthodontic problems: 55 (51.89%) showed crown loss, and average length of retained roots was 9.98 mm as measured on radiographs. A total of 97 (15,65%) had conservative or endodontic problems: deep caries, shifted beyond cemento enamel junction (CEJ) to root area (boundary of root apex of caries were presented above the average of 3.92 mm from CEJ toward root apex). A total of 34 (5.48%) cases had orthodontic and other problems. Conclusion: For proper prognosis of individual teeth, generalized judgment based on collected patient information, and treatment philosophy of clinicians will be required.
