What is the Best Root Surface Treatment for Avulsed Teeth?

Area of Science:

• Dental Traumatology
• Regenerative Dentistry
• Biomaterials Science

Background:

• Dental avulsion is a severe traumatic injury with significant risks to tooth survival.
• Effective management necessitates preserving pulp and periodontal ligament (PDL) cells.
• Current temporary storage media for avulsed teeth are not ideal, requiring further research.

Purpose of the Study:

• To review current management protocols for avulsed teeth, focusing on PDL and pulp cell viability.
• To evaluate various root surface treatments for delayed replantation to prevent root resorption.
• To highlight the potential of basic fibroblast growth factor (bFGF) in tooth structure regeneration.

Main Methods:

• Literature review of studies on dental avulsion management.
• Analysis of factors influencing avulsed tooth prognosis (extra-alveolar time, storage media, PDL status).
• Examination of root surface treatments including fluorides, steroids, alendronate, EMD, and bFGF.

Main Results:

• No single ideal storage medium for avulsed teeth currently exists.
• Various root surface treatments are explored to mitigate risks associated with delayed replantation.
• Basic fibroblast growth factor (bFGF) demonstrates significant potential for regenerating natural tooth structures and tissues.

Conclusions:

• Continued research is needed for optimal temporary storage solutions for avulsed teeth.
• bFGF presents a promising avenue for enhancing regenerative therapies in dentistry.
• Understanding bFGF mechanisms can drive innovation in tooth structure regeneration technologies.
