Dentoalveolar trauma and minor trauma as precipitating factors for medication-related osteonecrosis of the jaw (ONJ): a retrospective study of 149 consecutive patients from the Copenhagen ONJ Cohort

This study documented that dentoalveolar trauma precipitated ONJ in the majority of cases. However, even minor trauma, such as intubation and impression tray lesions, precipitated ONJ in a few cases (1%). Besides the occurrence of fistula to the skin and a difference in the male-to-female ratio, we found no significant difference between the spontaneous and trauma groups.
