Discriminating bacterial types in oral and maxillofacial space infections (OMSIs) via smelling diagnosis.

Objectives: To explore the feasibility of using gas chromatography-mass spectrometry (GC-MS) in the diagnosis of bacterial types of oral and maxillofacial space infections (OMSIs).

Methods: Staphylococcus aureus was cultured to produce a full spectrum of volatile organic compounds (VOCs). These VOCs were collected and identified using VOC collectors and GC-MS.
