Mesenchymal Stem Cells in Socket Healing and MRONJ

Area of Science:

• Oral biology
• Regenerative medicine
• Cell biology

Background:

• Tooth socket healing involves inflammatory, proliferative, and remodeling phases.
• Mesenchymal stem/progenitor cells (MSCs), particularly from periodontal ligament and bone lining cells, are crucial for healing.
• Medication-related osteonecrosis of the jaw (MRONJ) impairs socket healing by suppressing MSC activity.

Purpose of the Study:

• To review the biological processes of tooth socket healing.
• To elucidate the role of MSCs in socket healing.
• To explore MRONJ mechanisms and their link to impaired healing.

Main Methods:

• Literature review of current research on socket healing and MSCs.
• Analysis of cellular and molecular mechanisms involved in healing and MRONJ.
• Discussion of advancements in cell lineage tracing techniques.

Main Results:

• MSCs from various tissues contribute to socket healing, though their precise roles require further clarification.
• MRONJ conditions negatively impact MSCs, leading to apoptosis and delayed healing.
• Understanding MSC contributions is key to managing MRONJ complications.

Conclusions:

• Further research using advanced techniques is needed to fully understand MSC roles in socket healing.
• Enhanced knowledge of MSCs and MRONJ mechanisms can lead to improved therapeutic strategies.
• Optimizing socket healing and managing MRONJ are critical for successful dental procedures.
