Summary
For avulsed teeth, proper storage is crucial for saving the tooth. Milk is the most practical and effective storage medium for periodontal ligament cells when immediate replantation isn't possible.
Area of Science:
- Dentistry
- Dental Trauma Management
- Biomaterials
Background:
- Avulsed teeth require prompt management of pulp and periodontal ligament (PDL) cells for optimal prognosis.
- Inappropriate storage media can lead to PDL cell necrosis, increasing risks of ankylosis and replacement resorption.
- Choosing the correct storage medium is critical for successful avulsed tooth treatment.
Purpose of the Study:
- To review the literature on transport media for avulsed teeth.
- To evaluate the efficacy and practicality of various storage solutions for avulsed teeth.
- To identify the optimal storage medium for preserving PDL cell viability.
Main Methods:
- Literature review of PubMed/MEDLINE up to February 2010.
- Analysis of common storage media for avulsed teeth.
- Evaluation of media features, problems, and cell viability.
Main Results:
- HBSS, ViaSpan, and Eagle's medium show potential for PDL cell viability but have practical limitations (cost, availability).
- Milk is convenient, inexpensive, and readily available.
- Milk effectively maintains PDL cell viability after tooth avulsion.
Conclusions:
- Milk is the preferred storage medium for avulsed teeth when immediate replantation is not feasible.
- Practical considerations strongly favor milk over specialized media for emergency dental trauma care.
- Proper storage significantly improves the survival rate of avulsed teeth.
