The greatest efforts in the dental management of head and neck cancer patients treated with HNRT are focused on ORN prevention. 1, 2, 3 However, the management of ORN is a difficult task, requiring multidisciplinary specialized care. Alternatively, total necrotic bone removal surgery, in combination with systemic antibiotics, with complete wound closure is still considered the treatment of choice for ORN. Currently, there is no universal protocol for its treatment, which can be based on conservative approaches, such as local irrigation with chlorhexidine, non-surgical debridement, ultrasound therapy, hyperbaric oxygen therapy, pentoxifylline associated with a tocopherol regimen, and lowlevel laser and photodynamic therapy. 1, 2Īfter its onset, ORN has no cure, but it can be controlled.

It frequently affects the maxillary and mandibular bones, especially in the first 3 years after HNRT, with an incidence of 5%.
