The crowns and roots of primary molars at their cervical portions are more slender mesiodistally. This statement is __________.

• A. True
• B. False
• C. Only true for molars
• D. Only false for molars

Answer: (A)

The statement is accurate because the anatomical structure of primary molars shows a distinct tapering at their cervical portions, giving them a more slender appearance mesiodistally compared to permanent molars. This feature is important in pediatric dentistry as it relates to the function and aesthetics of primary teeth.

Primary molars are designed to accommodate the developmental processes of children, including the potential for future eruptions of permanent teeth. The slenderness enhances their role in guiding the eruption of succeeding permanent teeth and contributes to appropriate spacing in the dental arch. Additionally, this understanding is critical when considering treatment options, such as space maintainers or restorations, as it affects how these teeth anchor within the soft tissues of the surrounding gums and jaw.

This anatomical characteristic helps to differentiate primary molars from permanent molars, emphasizing the importance of recognizing these differences in pediatric dental practice. Therefore, the answer is true, as it accurately describes the morphology of primary molars in this specific context.
