Geristore by DenMat (Figure 1) is a time-tested material that has received numerous accolades from the dentists who use it. Some have even called Geristore a staple in their practices, thanks to the material’s high degree of biocompatibility and abundant indications for use.
That’s because Geristore is a self-adhesive, fluoride-releasing, resin-modified glass ionomer that offers ideal strength, a modulus of elasticity, self-adhesion, and low water sorption. This translates to a material that not only adapts in any clinical situation but will also stand the test of time.
Geristore’s unique dual-cure, hydrophilic, Bis-GMA formulation makes it ideal for many clinical situations. Furthermore, independent research has shown that it is exceptionally biocompatible with connective tissue. It self adheres to enamel, dentin, composite, semiprecious metal, porcelain, and gingiva. It also resists microleakage and has an ideal coefficient of thermal expansion and polymerization shrinkage.
Geristore’s dual-syringe, auto-mix delivery system includes intraoral tips, allowing the material to be extruded directly into the prep. It can be light or self cured, with a working time ranging between 90 and 120 seconds. The dual-cure formula ensures integrity in difficult-to-reach areas of the mouth.

CLINICAL CASE EXAMPLE
The patient presents with carious lesions at the subgingival margins of teeth Nos. 20 and 21. After a thorough cleaning, the authors prepare the tooth surfaces via caries removal (Figure 2). The tooth surfaces are then prepared with DenMat’s Etch ‘N’ Seal, followed by application of DenMat’s Tenure MPB (equal parts A/B mixed) (Figure 3). Four to 6 coats are applied to each tooth. This step, while optional, is suggested to ensure maximal bond strength. Next, the authors prepare the auto-mix syringe and firmly apply the intraoral tip. Geristore is then applied to teeth Nos. 20 and 21 (Figure 4). The authors then light cured the material and finished it using a 12- or 30-fluted bur. Finally, DenMat’s Gloss-N-Seal, a light-cured surface sealant, is applied to the restored area to protect it from wear, marginal staining, and breakdown (Figure 5). The finished result (Figure 6) will deliver for years to come, thanks to Geristore’s unique material properties.
