Background:
Eruption sequestrum (ES) is an uncommon condition characterized by irregular calcified tissues on the occlusal surfaces of erupting permanent molars, primarily in children. Despite its rarity, ES has been linked to potential complications, including gingivitis, occlusal trauma, and delayed tooth eruption.
Case Presentation:
This paper reports a multiquadrant ES case affecting the first molars of bilateral maxillary and mandibular arches in a 6-year-old pediatric patient. Intraoral examination revealed small, pale-yellow calcified tissues on the distal occlusal surfaces of the erupting first molars. Periapical radiographic evaluation revealed distinct radiopaque masses on the occlusal surfaces of the molars. Histopathologic examination identified the masses as nonviable compact bone tissue surrounded by chronic inflammation.
Conclusions:
This report enhances the understanding of tooth eruption disorders by documenting quadrant-wide ES, which ultimately provides insights into its diagnosis and treatment in pediatric patients.
