한국인 영구치 발거의 7가지 병인 분석

Abstract

This study aimed to analyze the etiologic factors of permanent teeth extraction in Koreans. Using the data from the electronic medical record (EMR) in the past 10 years, the study targeted 25182 adults whose teeth were diagnosed as hopeless and needing extraction. Oral diseases that cause the extraction of permanent teeth were classified into seven categories. The relationship between oral diseases and permanent tooth extraction was analyzed. Male patients had a higher tendency to need the extraction of permanent teeth than female patients. In male patients, the three major etiology for extracting permanent teeth were periodontal disease (34.4%), dental caries (27.7%), and impacted teeth (21.8%). In younger patients aged 21-30 years, impacted tooth (58.0%) and dental caries (40.3%) were the main cause for extraction, whereas in older patients 51-60 years of age, periodontal disease (28.0%) was the main cause. Upper third molars (76.7%) and lower third molar (63.2%) were extracted mainly due to dental caries. Lower second molars (26.1%) and upper third molars (22.9%) were the most affected teeth by periodontal disease. The study showed that extractions from periodontal disease occur at a higher rate than extractions from dental caries. During the 10 years that the study tracked, periodontal disease and dental caries showed a slight decrease in occurrence.
