Age and sex related change in tooth enamel thickness of maxillary incisors measured by cone beam computed tomography

An inverse association between enamel thickness and chronological age at all measurements above the CEJ (Cemento-enamel junction)was observed.

In contrast, there was an increase in IFP (Facial and palatal enamel thickness at the incisal edge ) , palatal, and IPED ( Incisal enamel pulpal distance ) enamel thickness with age.

Also, significant differences were found in enamel thickness between males and females, the enamel being thicker in females in relation to facial enamel thickness, enamel palatal thickness above CEJ and IET (Mid incisor enamel thickness)

While for IEPD (Incisal enamel pulpal distance) , the enamel thickness was greater in males compared to females.
