This correction is being published to correct the Tables. In Tables 2-4, corrections are underlined.

In Table 2, there was an overlap of 2 individuals included in “others”, which ranged from 12 (8.6%) to 10 (7.1%). In Table 3, 20 other oral cancer patients and 30 other patients with tumors in the head and neck did not present osteoradionecrosis (ORN), and they were added to a total of 139 patients. In Table 4, the incidence of ORN according to each antineoplastic treatment modality in 139 patients, was 10/60 (60.0%) radiotherapy (RT), 6/32 (18.8%) RT+chemotherapy (CT)+surgery, 4/30 (13.3%) RT+surgery, and 4/67 (5.9%) RT+CT. The changes in all tables did not change the order of incidence of the factors; thus, the changes clarify the mathematical doubts of readers without invalidating our study.

The authors apologize for any inconvenience this may have caused.
