Epinephrine absorption from retraction cord: a study in dogs.
Pharmacology and Therapeutics in Dentistry
|January 1, 1978
Summary
This study revisits epinephrine absorption from dental retraction cords used in fixed prosthodontics. Conflicting evidence suggests experimental models may influence absorption findings, necessitating further research.
Area of Science:
- Dentistry
- Prosthodontics
- Pharmacology
Background:
- Gingival retraction cords containing epinephrine are commonly used in fixed prosthodontic procedures.
- There is conflicting evidence regarding the extent of epinephrine absorption from these cords into the bloodstream.
Purpose of the Study:
- To re-evaluate the absorption of epinephrine from gingival retraction cord during fixed prosthodontic impression procedures.
- To identify potential reasons for discrepancies in existing research findings.
Main Methods:
- This report critically analyzes existing studies and experimental models.
- It does not present new experimental data but reviews previous findings.
Main Results:
- Conflicting evidence on epinephrine absorption persists.
- The variability in results is likely attributable to differences in experimental methodologies.
Conclusions:
- The question of epinephrine absorption requires further investigation.
- Future studies should focus on refining experimental models to yield more consistent results.
