Abstract
Fused teeth represent an uncommon developmental anomaly in which adjacent tooth buds unite to form a single enlarged structure, often leading to spacing discrepancies, malocclusion, esthetic concerns, and a frequent absence of permanent successors. Although more prevalent in the primary dentition, bilateral involvement is exceedingly rare and poses additional diagnostic and treatment challenges. This report describes three pediatric cases of mandibular primary tooth fusion associated with hypodontia of the successor incisors, confirmed radiographically. These cases underscore the importance of early clinical and radiographic evaluation, multidisciplinary management, and long-term follow-up to minimize complications and support optimal dental development.
