Abstract
The purpose of this research, which was executed with 200 patients whose chief complaint was the extraction of the mandibular third molar, was to examine the effect that eruption state of the mandibular third molar has on the growth of pericoronitis. The conclusion about distribution of left and right mandibular third molar, angulation, impaction degree, anterior border of mandibular ramus and the interval from mandibular second molar to mandibular third molar was drawn by chi-square test. 1. There was correlation between pericoronitis and position of the mandibular third molar according to age. 2. In angulation of mandibular third molar, mandibular third molar most likely to be afflicted with pericoronitis is mesioangular. 3. The impaction degree between mandibular third molar and the growth of pericoronitis was given in the order of Level a, Level c and Level b. 4. In the anterior border of mandibular ramus with mandibular third molar, pericoronitis was easily generated in the order of Class II, Class I and Class III. 5. The shorter the interval from distal cementoenamel junction of mandibular second molar to mesial cementoenamel junction of third molar became, the more easily pericoronitis was generated.
본 연구는 하악 제3대구치의 맹출 양상이 치관주위염의 발생에 미치는 영향을 조사하고자 양산시에 소재한 N치과병원에 하악 제3대구치 발거를 주소로 내원한 환자 200명을 대상으로 조사연구를 실시하였다. 하악 제3대구치의 좌 우측 분포도, 경사도, 매복정도, 하악지 전연에서의 위치, 하악 제2대구치와 제3대구치 사이의 거리는
