- This study aimed to analyze the main reasons for the extraction of permanent teeth among Koreans with oral diseases. The electronic medical record data for past 10 years was used in a target population comprising of 26,795 adults diagnosed with oral disease and scheduled to undergo permanent tooth extraction. The oral diseases were classified into periodontal disease, dental caries, impacted teeth, prosthodontic treatment, orthodontic treatment, tooth fracture, trauma, and others. The relationship between these diseases and permanent tooth extraction was analyzed. Permanent teeth were extracted due to periodontal disease (34.5%), dental caries (26.6%), and tooth impactions (22.3%). Permanent teeth were extracted as the cause of dental caries (28.6%) and periodontal disease (45.9%) from patients in 26-35 and 46-55 years of age respectively. The mandibular first molars (17.2%), mandibular second molars (16.0%), maxillary first molars (14.7%), and maxillary second molars (14.3%) were extracted due to dental caries. The incidence of periodontal disease was highest in the mandibular central incisor (72.6%; p<0.05). These findings indicated that periodontal disease was the chief cause of extraction of permanent teeth among Korean adults.
