Geographical diversity in root canal anatomy of primary molars and its clinical implications: A systematic review and meta-analysis.

Background: Anatomical variability in primary molars across geographic regions presents significant challenges in pediatric endodontics. Regional differences in root canal morphology complicate diagnosis and treatment planning, emphasizing the need for population-specific insights.

Objective: This review synthesizes evidence on geographical variations in root canal anatomy, focusing on population-specific characteristics and their clinical relevance.
