Summary
Propolis effectively preserves avulsed teeth for reimplantation, with a 6-hour storage period showing better results than 60 minutes. This natural substance aids in maintaining cellular viability for successful tooth repair.
Area of Science:
- Dental Traumatology
- Biomaterials Science
- Regenerative Dentistry
Background:
- Avulsed tooth reimplantation requires preserving cellular viability to repair the periodontal ligament and prevent root resorption.
- Propolis, a natural resinous substance, exhibits properties that can maintain cellular viability.
Purpose of the Study:
- To evaluate propolis as a storage medium for avulsed teeth.
- To determine the optimal storage duration of avulsed teeth in propolis.
Main Methods:
- Sixty rat incisors were divided into five groups: storage in propolis (60 min and 6 h), milk (6 h), dry (60 min), and immediate reimplantation.
- Root canals were filled with calcium hydroxide paste before reimplantation.
- Microscopic and morphometric analyses were performed after 15 and 60 days.
Main Results:
- Propolis storage for 6 hours (Group II) showed comparable results to milk storage (Group III).
- Dry storage (Group IV) led to a higher occurrence of replacement resorption compared to other groups.
- Storage in propolis for 60 minutes (Group I) resulted in less periodontal ligament-like connective tissue and cementum compared to other groups.
Conclusions:
- Propolis is a viable storage medium for avulsed teeth.
- A 6-hour storage period in propolis is more effective than a 60-minute period for preserving tooth viability and promoting successful reimplantation outcomes.
