What Researchers Did
Researchers conducted an in-vitro study to investigate if hyperbaric environments or increased oxygen partial pressure correlate with the corrosion of three types of dental alloys used in divers.
What They Found
No correlation was found between increased ion solubility, as a measure of corrosion, and increased ambient pressure for the three tested alloys. However, the reduced-gold-content alloy released zinc ions at twice the weekly recommended dose, and the palladium-based alloy showed only slight increases in gallium and silver ion solubility under hyperbaric conditions.
What This Means for Canadian Patients
Canadian patients who are divers with dental restorations can be reassured that hyperbaric conditions likely do not significantly increase the corrosion risk for these specific alloys. This suggests that current dental materials may be suitable for individuals engaging in diving activities.
Canadian Relevance
There is no direct Canadian connection mentioned in this study.
Study Limitations
A limitation of this study is its limited sample size.
