Tooth discoloration induced by endodontic sealers
Oral Surgery, Oral Medicine, and Oral Pathology
|January 1, 1986
Summary
Tooth discoloration after endodontic therapy is common. This study found that various endodontic sealers cause measurable tooth staining, with Riebler's paste being the most severe and Diaket the mildest.
Area of Science:
- Dentistry
- Endodontics
- Dental Materials Science
Background:
- Tooth discoloration is a frequent complication following endodontic therapy.
- Key causative agents include blood, necrotic pulp tissue, and endodontic filling materials.
Purpose of the Study:
- To evaluate and compare the in vitro tooth-staining potentials of commonly used endodontic sealers.
- To quantify the degree of discoloration induced by different sealers over time.
Main Methods:
- Extracted premolars were used for in vitro color assessment.
- Pulp cavities were filled with eight different endodontic sealers: Zinc oxide eugenol cement, Grossman's cement, AH26, Diaket, N2, Riebler's paste, Tubliseal, and Endomethasone.
- Tooth color was visually assessed on external surfaces before sealer application and at regular intervals up to 6 months.
Main Results:
- All tested endodontic materials induced measurable tooth discoloration within three weeks.
- Riebler's paste resulted in the most significant tooth discoloration.
- Diaket exhibited the mildest staining effect, with other materials showing intermediate levels of discoloration.
Conclusions:
- The choice of endodontic sealer can significantly impact tooth color post-treatment.
- Riebler's paste and Diaket represent the extremes of the staining potential among the evaluated materials.
