Maxillary canine

Y = 65.251–0.8843x (R2 = 96.1)

Y = 65.511–0.8936x (R2 = 95.3)

Maxillary second premolar

Y = 63.137–0.8472x (R2=97.4)

Y = 63.874–0.8637x (R2 = 97.3)

Mandibular canine

Y = 64.768–0.8815x (R2 = 94.7)

Y = 64.683–0.8846x (R2 = 93.1)

Mandibular first premolar

Y = 63.51–0.8795x (R2 = 90.8)

Y = 64.247–0.8959x (R2 = 89.4)

  1. Y indicates estimated age while X represents CPCI. R2 indicates regression coefficients
