Inflammatory internal root resorption is a resorptive pathological process that progressively des-troys intra-radicular dentin and dentinal tubules. With a multifactorial etiology, it is diagnosed through radiographic examinations, and it is crucial to initiate endodontic treatment as soon as possible to halt damage to dental structures and prevent their weakening. Recent technological advances have led to the development of numerous dental materials, such as bioceramic cements, which are indicated for the treatment of this pathology. The objective of this study is to demonstrate the treatment of internal root resorption in tooth 13 using a bioceramic cement through a clinical case report. The use of repair cements, such as bioceramics, combined with early diagnosis and appropriate treatment, has shown to be effective in cases of internal resorption, reducing the risk of dental structure weakening and enabling the retention of the tooth in the oral cavity.
