Abstract
Age determination in children have been criticized because they rely on subjective estimations of tooth development, as seen in radiographs.
This study was undertaken to obtain the objective estimation of developing teeth.
? panoramic radiograph of 2E males and 254 females ranging from 6 to 14 years of age were studied.
? structures measured were crown height, apex width and root length
? data were statistically investigated with SPSS/PC + package. `
Th a results were as follows ;
4. With the aid of a multiple regression model, a linear relationship between some of these distances and age
was shown.
2 In the total rnaterial(6-14yr) and four-yr. intervals, linear equations are as follow
Boys
6-14 age = 683 + 145.6 44RL + 126.6 45RL + 71.1 46DRL - 161.3 46DAW
6-10 age = 1202 + 72.6 46DRL + 100.2 44RL + 75.1 45RL
8-12 age = 3818 + 75.9 45RL - 190.9 44AW
10-14 age = 4151 + 58.6 45RL - 84.0 45AW - 130.6 44AW
Girls
6-14 age = 1587 + 104.9 45RL + 113.4 44RL - 233.1 46DAW + 81.4 47DRL - 255.9 46MAW
6-10 age = 1821 + 55.8 46DRL + 672 45RL - 184.2 46MAW + 56.3 44RL
8-12 age = 2435 + 68.2 45RL + 71.3 44RL
10-14 age = 3485 + 49.9 47DRL - 51.3 45AW - 179.9 47DAW + 33.4 45RL + 39.4 44RL
(DRL, length of distal root in molars. RL, root length in premolars. DAW, width of distal apex in molars. MAW,
width of mesial apex in molars. AW, width of apex in premolars)
