A Novel Approach to Monitoring Graft Neovascularization in the Human Gingiva

Overview

This study introduces a protocol for measuring microcirculation in human oral mucosa using laser speckle contrast imaging (LSCI). It highlights the monitoring of wound healing after vestibuloplasty combined with a xenogenic collagen graft through a clinical case.

Key Study Components

Area of Science

• Neuroscience
• Clinical Imaging
• Oral Biology

Background

• Microcirculation is crucial for understanding wound healing processes.
• LSCI is a non-invasive technique that assesses blood perfusion.
• The technique offers good repeatability and reproducibility.
• It can monitor changes in gingival microcirculation over time.

Purpose of Study

• To establish a protocol for measuring microcirculation in oral mucosa.
• To demonstrate the application of LSCI in clinical settings.
• To track wound healing in patients undergoing vestibuloplasty.

Methods Used

• Laser speckle contrast imaging setup and calibration.
• Patient positioning in a dental chair for optimal imaging.
• Use of a cuff and vacuum pillow for patient comfort.
• Monitoring of blood perfusion in a surgical site up to six square centimeters.

Main Results

• Successful measurement of microcirculation in the oral mucosa.
• Effective tracking of wound healing post-surgery.
• Demonstrated non-invasive nature of LSCI in clinical practice.
• Provided insights into individual disease progression.

Conclusions

• LSCI is a valuable tool for monitoring oral mucosal microcirculation.
• The protocol can enhance clinical assessments of wound healing.
• Further studies may expand its application in other areas of oral health.
