Why it matters for dental
Endodontists and restorative dentists now have peer-reviewed data showing that saliva contamination during retrograde filling can compromise MTA seal integrity, while Geristore maintains its seal regardless—directly affecting case selection and isolation protocols for apical surgery.
Key points
- Study compared Geristore vs. MTA as root-end fillings under dry vs. saliva-contaminated conditions.
- MTA sealing ability significantly decreased in saliva-contaminated environment; Geristore seal remained stable.
- Results suggest Geristore may be preferable when ideal isolation is difficult during periapical surgery.
- Published as a controlled laboratory study; findings apply to both specialists and general dentists performing apicoectomies.
