Gingivitis resolution followed by optical coherence tomography and fluorescence imaging: A case study.

Area of Science:

• Biomedical Optics
• Oral Medicine
• Periodontology

Background:

• Gingivitis is a common oral condition that can progress to periodontitis if untreated.
• Monitoring the resolution of gingivitis is crucial for effective treatment and prevention of periodontal disease.

Purpose of the Study:

• To investigate the utility of optical coherence tomography (OCT) and light-induced autofluorescence (LIAF) in monitoring gingivitis resolution.
• To characterize the microvascular and structural changes during gingivitis resolution using advanced imaging techniques.

Main Methods:

• A case study involving a 10-day monitoring period of gingivitis resolution.
• Utilized optical coherence tomography (OCT) for structural imaging and functional angiography to assess vascular changes.
• Employed light-induced autofluorescence (LIAF) to detect mature plaque.

Main Results:

• OCT successfully captured dynamic changes during gingivitis resolution, including angiogenesis in acute inflammatory regions.
• LIAF identified red-fluorescent signals indicative of mature plaque at inflamed sites.
• Gingival thickness decreased by an average of 140 ± 26 μm; angiogenesis-related vessels reduced exponentially.

Conclusions:

• OCT and LIAF are effective tools for visualizing and quantifying changes during gingivitis resolution.
• The study demonstrated angiogenesis in acute gingivitis and its subsequent reduction upon inflammation resolution.
• These imaging modalities offer valuable insights into the microvascular dynamics of periodontal inflammation.
