STACKED IMPACTED MANDIBULAR MOLARS ASSOCIATED WITH PRIMARY FAILURE OF ERUPTION: A CBCT CASE REPORT

Abstract

Tooth eruption is a complex, biologically regulated process involving coordinated interactions among the dental follicle, gubernacular cord, and dental lamina remnants which is important in a process that is essential for establishing proper occlusion and masticatory efficiency. 

OBJECTIVES: The present case report aims to describe the radiographic features of primary failure of eruption (PFE) in permanent mandibular molars using cone-beam computed tomography (CBCT). It seeks to evaluate the pattern and positioning of multiple impacted molars in the mandibular posterior region and to assess the role of retained deciduous teeth in disrupting the normal eruption pathway. It further emphasizes the importance of CBCT in accurate diagnosis and treatment planning, while highlighting the need for early detection and appropriate management to prevent complications affecting occlusion, jaw development, and overall oral function.

METHODS: This case report describes a 28-year-old female of East Indian descent who presented with a long-standing history of missing tooth in left mandibular region which was diagnosed after proper clinical examination then radiographical evaluation was done using CBCT.

RESULTS: The CBCT imaging revealed multiple impacted molars arranged in a stacked configuration over each other in the left mandibular region, providing comprehensive insight into their position, orientation, and relationship with adjacent anatomical structures. CONCLUSION: This highlights the importance of early diagnosis using 3D imaging modalities like CBCT and intervention to prevent complications affecting occlusion, jaw development, and overall oral function.
