ABSTRACT
This study was performed to apply the submentovertex cephalometric radiograph to mandibular condylar fractures. Because the left and right structures are not overlaped in the submentovertex radiograph, the dimension and position of mandibular condyle can be clearly identified in this view. The subjects consisted of 40 normal adult patients, twenty healthy males and females with no medical and dental histories. Specific angular and linear measurements were made from each submentovertex radiograph and computerized statistic analysis was carried out. The results were as follows. 1. There was no sexual difference in the angular measurements such as intercondylar angle, angle between condylar axis and mandibular line, and angle between condylar axis and TPA. Though no sexual difference was seen in the linear measurements related to the position of the condyle such as L-TSA, L-TPA, and MSP-Pog, measurements related to the dimension of the condyle such as condylar thickness, condylar width, L-MSP, L-Cpp, MSP-Cpp, and L-Pog were lager in male than female. 2. Statistically, significant difference between right and left values was seen only in the value of condylar width and L-Cpp(p<0.05). But the correlation coefficient of the condylar width between right and left side was very high that it could be thought very useful to compare the left and right side value clinically. 3. In the correlation analysis between left and right side condylar width, L-Cpp, and L-Pog were showed high relation. On the other hand the value of L-TSA was showed low relation. The other measurements were showed relatively high relation. 4. The difference between the maximum and minimum value of each measurement was considerable that the individual variation of measurement was relatively high.
