Oral Mucosa Capillaroscopy: A Narrative Review

Area of Science:

• Oral Medicine
• Medical Imaging
• Microcirculation Research

Background:

• Oral diseases and lesions can alter the oral cavity's microvasculature.
• Current methods for observing these changes often rely on biopsy samples.
• There is a need for in-vivo techniques to characterize microvascular changes in oral tissues.

Purpose of the Study:

• To review the literature on capillaroscopy for imaging oral mucosa microvasculature.
• To explore its applications and diagnostic/prognostic significance in various oral conditions.
• To highlight the need for further research, especially in oral oncology.

Main Methods:

• Literature review of capillaroscopy techniques.
• Analysis of preliminary studies on oral mucosa microvasculature imaging.
• Examination of diagnostic and prognostic implications in oral diseases.

Main Results:

• Capillaroscopy, using polarized light and magnification, shows promise for enhanced oral mucosa microvasculature imaging.
• Preliminary studies indicate potential for capillaroscopy in visualizing microvascular alterations.
• Limited literature currently exists, particularly concerning its diagnostic and prognostic value.

Conclusions:

• Capillaroscopy is a promising technique for in-vivo imaging of oral microvasculature.
• Further research is essential to establish its clinical utility, especially in diagnosing and predicting outcomes for potentially malignant oral disorders and cancers.
• Oral capillaroscopy holds potential significance in the field of oral oncology.
