Nowadays, it is considered as a frequent and alarming problem for the dental preservation. Objective: to describe a clinical case of external radicular reabsorption. Clinical case: a thirty-eight-year-old, black, female patient with a history of adenohypophysis microadenoma and rheumatoid arthritis that was under treatment with 0, 5 milliliters of methotrexate administered intramuscularly once a week. The patient came to the stomatological consultation for a routine examination. Occlusal interferences, extensive fillings and edentate gaps without rehabilitation were detected in the clinical examination. External radicular reabsorption in different dental groups and calcification of the apical third in bicuspid area were seen in the X-rays. Besides, it was seen that the bone kept good osseous density as well as the cortical. The patient was asymptomatic. She said suffering from bruxism and onychophagia. When she was a child she underwent orthodontic treatment with a removable appliance because of vestibular version and tongue thrust habit. Conclusions: a combination of internal and external causal factors that brought on the appearance of external reabsorption in all the dental groups was observed. The presence of rheumatoid arthritis, adenohypophysis microadenoma and the use of methotrexate had a vital importance.
