Familial, Nonsyndromic, Generalized Radiculomegaly Affecting Both Dentitions: The First Reported Case.

Aim and background: Radiculomegaly is a rare anomaly characterized by the abnormal elongation of tooth roots. Its etiology is poorly understood and is often diagnosed accidentally during routine dental or radiographic evaluations. The condition may pose challenges while carrying out root canal treatment, extraction, or orthodontic tooth movement.

Case description: This article highlights the first ever reported case of familial, nonsyndromic, generalized radiculomegaly affecting the primary and permanent dentitions in a 13-year-old male who had visited the Department of Pedodontics and Preventive Dentistry for a dental checkup. Clinical examination revealed a delay in eruption since his dentition was inconsistent with his age. An orthopantomograph showed the presence of primary and permanent teeth with longer roots than usual.

Conclusion: A diagnosis of radiculomegaly was made from full-mouth CBCT tooth measurements that confirmed longer roots. Orthopantomographs of his sibling and father revealed similar findings.

Clinical significance: Radiculomegaly is a rare condition. It is generally asymptomatic; however, it may cause difficulties during endodontic treatment. Therefore, early diagnosis is beneficial.
