A micro-computed tomography examination of primary double teeth from the Muslim necropolis of Macael Viejo (13th-16th centuries; Almeria, Spain)

A child aged 5±1 years with abnormally developed mandibular incisors was discovered during the analysis of a skeletal assemblage from the late medieval/early modern necropolis of Macael Viejo (c. 13th–16th, Almería, Spain). The mandibular right deciduous incisors (81 and 82) were found to have developed a rare abnormality – a fused crown and single root. The identification, descriptions, and differential diagnoses of the anomaly were performed using morphological analyses and radiographic means. This article aims to present a case of fusion of two adjacent primary teeth displayed by a non-adult and analyse the applications and the potential of microcomputed tomography (Micro-CT) in the analysis of tooth crown and root canal morphology in dental anomalies.
