Inside Cover: A noninvasive imaging and measurement using optical coherence tomography angiography for the assessment of gingiva: An in vivo study (J. Biophotonics 12/2018)

Oral diseases are traditionally assessed and scored via indices such as gingival index, plaque index, etc. This procedure is lengthy, invasive (physical probing), and may cause pain/bleeding during the assessment. The assessment may also be subjective to the clinicians in different regions of the world. Detailed assessment using bio‐marker such as gingival crevicular fluid (GCF) is available as a scientific tool for quantification of gingival disease. However, GCF still has the same issues regarding time, invasiveness, and cost. In this paper, we propose a non‐invasive imaging technique, called optical coherence tomography (angiography). This new imaging technique can quantify micrometer‐size blood vessels and features in the gingiva (rete ridges, connective tissues, etc.) that may be used as standard assessment for gingiva diseases.
