What is the most favorable eruption sequence of the primary dentition?

The most favorable eruption sequence of the primary dentition, which is often indicated as ABCDE, aligns with the typical order in which primary teeth erupt. This sequence reflects the anatomical development and timing of tooth eruption, which is generally established by both genetic programming and developmental growth patterns in children.

In this sequence, the central incisors (A) are followed by the lateral incisors (B), the first molars (C), the canines (D), and finally the second molars (E). This order is considered ideal not only because it allows for optimal spacing and alignment of the teeth but also because it supports the proper development of oral and facial structures. Each stage of eruption plays a critical role in preparing the dental arch for future permanent teeth, ensuring that there is adequate space for their eruption in alignment with jaw growth.

This eruption pattern is widely recognized in pediatric dentistry as part of normal dental development, and understanding this sequence helps practitioners monitor and guide the growth of a child's dentition effectively. Other sequences, such as those represented in the remaining options, do not reflect the standard order of eruption seen in clinical practice, which can lead to potential misalignments and spacing issues in the bite and overall dental health.
