The data that has been obtained is then processed by statistical analysis with SPSS for Windows, with an inclusion level of p <0.05.
 Results: This study showed that the London Atlas was better and more accurate than the Schour-Massler Atlas with a lower mean error and there was no significant difference between the London Atlas dental age estimation and chronological age with p value = 0.426 in the left region and p = 0.429 in the right region (p>0.05).
