Background: During dental procedures using oxygen supplementation, a highly saturated oxygen environment is potentially created due to oxygen pooling in the oral cavity. High oxygen concentrations pose a serious threat due their link to increase flame ignition and prolonged flame. It is crucial to obtain a better understanding of the effects of supplemental oxygen during dental procedures and oxygen concentration levels in the oral cavity to prevent future surgical fires.
Objective: To utilize an intraoral laboratory-based model to measure oxygen concentrations over time when delivering supplemental oxygen at 3 L/min.
Design: Oxygen concentrations were recorded during lab-based procedures simulating oxygen supplementation of 3L/min to an oral cavity with the introduction of the high-speed dental suction tip, the Yankauer suction tip, and the standard fixed tip saliva ejector when introduced at specified times.
Hypothesis: For test conditions in which supplemental oxygen is supplied per trial, FiO2 measured in the oral cavity will reach levels >21%. We also hypothesize that oxygen pooling, if found, will be diminished equally with the introduction of the high-speed dental suction tip, the Yankauer suction tip, and the standard fixed tip saliva ejector when introduced at the specified times in the test protocol.
Conclusions: The conclusions from this research will allow dental providers in a surgical setting to limit the pooling of oxygen in the oral cavity during procedures, in order to help eliminate the potential for surgical fires.
