内容記述 |
We have investigated the transition of the third molar, or wisdom teeth, of undergraduates students at our college during the academic year, 1985-1986. These data were compaed to previous reports compiled from 1977 to 1984. 1) The four wisdom teeth were symbolically represented in sixteen combinations; Cases where all four teeth erupted ( ) or where no teeth erupted ( ) were common, while cases of only one tooth erupting in each jaw ( )were rare. 2) There appears to be no relationship between a tooth's eruption and its visibility on x-ray film. On the average, one tooth seen on the x-ray film will erupt. 3) According to the data from 1977-1984, 4.4% of all erupted teeth had incomplete root apices, compared with 3% for the 1985-1986 sample. However, of completely impacted teeth, the percentages increased from 24% to 46%, respectively. 4) The inclination of the wisdom teeth examined was mostly vertical in the maxilla, while it was mesial or horizontal in the madible. This inclination was similar to that in previous reports. 5) The percentage of the wisdom teeth restored was higher than that of the previous reports. The number of teeth restored by resin filling, were 16. In contrast, none were seen in previous reports. 6) The percentage of unerupted teeth other than wisdom teeth was 1.1% which is less than the 3.7% in previous reports. Completely impacted teeth other than wisdom teeth were 9 out of 266 people studied. This number in less than that in the previous reports, which was 21 in 1287 people, but the percentage is higher. 7) The percentage of extracted wisdom teeth was 22.0% (135 out of 613), which was almost similar to the percentage of 19.7% (613 out of 3110) shown in the previous reports, If is important to note that 130 wisdom teeth out of 135 were extracted without anti-inflammatory treatment during dental clinical training. 8) The percentage of extracted wisdom teeth with vertical inclination was 64.5% (404 out of 626). This percentage is similar to that of 63.7% (1981 out of 3110) shown in previous reports. |
