What Researchers Did
Researchers conducted a randomized controlled trial to evaluate if hyperbaric oxygen therapy prevents osteoradionecrosis after dental procedures in patients with prior head and neck radiation.
What They Found
Out of 100 patients analyzed, the incidence of osteoradionecrosis at 6 months was 6.4% in the hyperbaric oxygen group and 5.7% in the control group. This difference was not statistically significant (odds ratio, 1.13; P = 1), although patients receiving hyperbaric oxygen reported fewer acute symptoms.
What This Means for Canadian Patients
Canadian patients undergoing dental procedures after head and neck radiation therapy should be aware that hyperbaric oxygen therapy may not prevent osteoradionecrosis. Current evidence suggests that this treatment does not significantly reduce the risk of this serious complication.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is the analysis of only 100 out of 144 randomized patients for the primary endpoint, potentially impacting statistical power.
