Table 3. Calculation of dental age (DA) using newly developed models in Boys and Girls, separately.

Model Formula
Boys
31-37 (Seven- teeth) DA= 4.396 + Sum of coefficients assigned to the stages of teeth in the model
31 33 34 35 36 37 (Six- teeth) DA= 4.544 + Sum of coefficients assigned to the stages of teeth in the model
31 33 34 36 37 (Five- teeth) DA= 4.664 + Sum of coefficients assigned to the stages of teeth in the model
31 33 34 37 (Four- teeth) DA= 5.451 + Sum of coefficients assigned to the stages of teeth in the model
33 34 37 (Three- teeth) DA= 6.069 + Sum of coefficients assigned to the stages of teeth in the model
34 37 (Two- teeth) DA= 5.370 + Sum of coefficients assigned to the stages of teeth in the model
34 (One- tooth) DA= 5.828 + Sum of coefficients assigned to the stages of teeth in the model
Girls
31-37 (Seven- teeth) DA= 5.095 + Sum of coefficients assigned to the stages of teeth in the model
32 33 34 35 36 37 (Six- teeth) DA= 5.077 + Sum of coefficients assigned to the stages of teeth in the model
32 33 34 36 37 (Five- teeth) DA= 5.079 + Sum of coefficients assigned to the stages of teeth in the model
32 33 34 37 (Four- teeth) DA= 5.122 + Sum of coefficients assigned to the stages of teeth in the model
32 34 37 (Three- teeth) DA= 5.350 + Sum of coefficients assigned to the stages of teeth in the model
34 37 (Two- teeth) DA= 5.350 + Sum of coefficients assigned to the stages of teeth in the model
37 (One- tooth) DA= 5.771 + Sum of coefficients assigned to the stages of teeth in the model
