This novel system allowed for a consistent and repeatable assessment of the gingival microvasculature. However, there was some evidence of possible pressure artefacts in those cases where the measurements of separation between vessels exceeded 150 μm.

There is an association between the presence of vascular microhemorrhage and branched dilated microvessels in the tissues lining the clinically healthy GC. Loss of ECG might be part of the inflammatory process in these tissues.

In vivo spectroscopic hemoglobin optical density ratios in oral mucosal microvessels show a qualitatively consistent result within the expected in vitro parameters.
