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%).
