What Researchers Did
Researchers conducted a systematic review to evaluate the efficacy of pre- and postirradiation hyperbaric oxygen therapy in preventing osteoradionecrosis after tooth extraction in previously irradiated patients.
What They Found
Out of 696 retrieved citations, 14 publications (1 randomized clinical trial, 8 cohort-controlled studies, and 5 observational studies) met the inclusion criteria. The analysis revealed insufficient evidence to definitively conclude that hyperbaric oxygen therapy prevents osteoradionecrosis after tooth extraction in irradiated patients.
What This Means for Canadian Patients
Canadian patients undergoing tooth extraction after radiation therapy should be aware that current evidence does not definitively support hyperbaric oxygen therapy for preventing osteoradionecrosis. Decisions regarding this therapy should be made in consultation with their healthcare providers, considering individual circumstances.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
Limitations included small sample sizes in most studies, lack of specific inclusion/exclusion criteria, variations in hyperbaric oxygen protocols and radiation dosages, and limited reporting on key procedural details.
