Torus Palatinus Osteonecrosis Related to Bisphosphonate: A Case Report

INTRODUCTION: Osteonecrosis of the palate is a rare condition which is even rarer when occurring on a torus palatinus and associated with bisphosphonate (BP). CASE PRESENTATION: We report an uncommon case of osteonecrosis of a torus palatinus. Our patient was a 67-year-old white female who presented with a painful intraoral ulcer associated with necrotic bone tissue of her torus palatinus, due to the chronic use of alendronate. CONCLUSION: We point out the possible causative relationship of BPs and osteonecrosis on torus growth. It is very important to know that torus palatinus and the use of BPs are risk factors for osteonecrosis of the maxilla.
