Abstract :
Multiple Idiopathic External Apical Root Resorption (MIERR) is a rare, aggressive dental condition of unknown origin that occurs spontaneously in otherwise healthy individuals without any identifiable systemic or local causes. It is characterized by progressive resorption of the apical portions of multiple tooth roots, often detected incidentally on radiographs. Clinically, affected teeth usually remain asymptomatic and vital until advanced stages, when significant root loss may compromise tooth stability. The etiology remains unclear, with proposed mechanisms involving genetic predisposition, immune dysregulation, or unrecognized local factors. Diagnosis is primarily radiographic, requiring careful exclusion of known causes of root resorption such as trauma, orthodontic treatment, or periapical pathology. Management focuses on regular monitoring, conservative intervention, and maintaining oral function for as long as possible, though severe cases may necessitate tooth extraction. Further research is needed to elucidate the pathogenesis and develop effective preventive or therapeutic strategies for MIERR.
