What Researchers Did
Researchers retrospectively evaluated a prophylactic hyperbaric oxygen therapy (HBOT) protocol and its outcomes in adults undergoing dental extractions after head and neck radiotherapy.
What They Found
Among 121 individuals, osteoradionecrosis (ORN) occurred in 9.1% and delayed healing in 3.3%. Fifteen individuals (12.4%) could not complete the HBOT protocol. ORN was significantly associated with age (P=0.006) and alcohol consumption was a significant predictor.
What This Means for Canadian Patients
For Canadian patients undergoing dental procedures after head and neck radiotherapy, prophylactic hyperbaric oxygen therapy may reduce the risk of osteoradionecrosis. Patients who are younger males or consume alcohol might still face a higher risk of ORN despite prophylaxis.
Canadian Relevance
This study was conducted in Australia and does not have a direct Canadian connection.
Study Limitations
As a retrospective study, it is subject to limitations such as potential selection bias and reliance on existing medical records.
