The purpose of this study was to establish the co-relation between the Dental age & the Chronological age of children in their mixed dentition period for Pakistani Sample. OPG & Dental casts of a total of 50 children were assessed. Selected children had the following characteristics: Age 6-12 years, no sagital, vertical or transverse skeletal discrepancy, no supernumerary or congenitally missing teeth. The mean age of the sample was 10.28 years. 48% were females and 52% were males. The results are as follows, Co-relation between the Dental age and the Chronological age is r=0.802 and r2=0.64. Co-relation between the Dental age and the Chronological age in boys is r=0.83 and r2=0.69. Co-relation between the Dental age and the Chronological age in girls is r=0.77and r2=0.59. Results showed that co-relation is not strong enough. In other words teeth erupt with considerable degree of variability from the Chronological age standards.
