Abstract
서울大學校 齒科大學 放射線學 敎室에 保管된 全顎 X-線 film중 判讀可能한 515名 X-線
film을 觀察한 結果 다음과 같은 知見을 얻었다.
1. 第 3 大臼齒를 除外한 14,420個의 齒牙 중 缺損齒 174, 埋伏齒 16, 蝕齒 161, 充塡 및
金冠裝着齒 1,162個였다.
2. 第 3 大臼齒의 埋伏率은 約 18.7%이고 缺損率은 33.4%였다.
3. 齒根端 部位의 觀察을 要하는 齒牙는 178例(1.2%)였고 이 중 根端病巢가 確認된 例는
119個 (0.8%)로 나타났다.
4. 根端病巢의 存在와 크기는 根管治療의 正確度와 密接한 關係가 있는 것으로 나타났고
上下顎 第1 大臼齒에 가장 많은 根端病巢가 분포(41%) 되었으며, 上下顎 견치가 가장 낮은
頻度(1.7%)를 보였다.
#초록#
The author examined 515 full mouth roentgenograms stored in the Dept. of Oral
Radiology, College of Dentistry, Seoul National University. For evaluating the efficiency
of the routine full mouth roentgenogram, each of abnormal conditions such as impacted
teeth, missing, caries, crown, filling and apical lesions was observed.
The results obtained were as follows ;
1. Among 14,420 teeth examined, missing teeth were 174, impacted 16, caries 161 and
treated 1,162.
2. The incidence of impacted third molar was close to 18.7 percent and the incidence
of missing third molar was about 33.4 percent.
3. Among carious and treated teeth, 178 teeth (1.2%) were needed observation of root
apex. And of these teeth, 119 teeth (0.8%) were observed with apical lesion.
4. There is a considerable relation between the incidence or size of apical lesion and
the accuracy of endodontical treat.
5. Among the teeth with apical lesion, upper and lower first molars were most
frequent (about 41%), upper and lower canine were rare (about 1.7%).
