Anatomical Differences Between Primary and Permanent Teeth

Abstract

The human dentition undergoes significant changes as a child grows into adulthood, transitioning from primary (temporary) teeth to permanent (adult) teeth. These two sets of teeth not only differ in function but also in their structural and morphological characteristics. Understanding the anatomical distinctions between primary and permanent teeth is crucial for dental professionals, as it influences treatment planning, diagnostics, and the prevention of dental issues. This article explores the key anatomical differences between these two sets of teeth, including size, shape, root structure, enamel thickness, eruption patterns, and their clinical implications.
