A Critical Review of the Role of Geristore® in Contemporary Endodontics.

Abstract

Introduction: Geristore® (GS) is an advanced dual-cure resin-modified glass ionomer with favourable biological and physical properties, including biocompatibility, fluoride release, and excellent sealing ability. Originally developed for restorative purposes, its clinical versatility has nonetheless extended into endodontics. The current critical review primarily aims to evaluate the biological characteristics, endodontic applications, and possible clinical potential of GS as a biomaterial in modern endodontic practice.

Methods: A comprehensive literature search was conducted across major databases (MEDLINE, PubMed, Scopus, Cochrane, EMBASE, Google Scholar, and grey literature) without restrictions on date and/or language. Relevant peer-reviewed studies on the composition, properties, and endodontic uses of GS were identified, screened, investigated, and critically analysed.

Results: Geristore® has demonstrated promising outcomes in endodontic procedures, e.g., root-end filling, perforation repair, vital pulp therapy, retrograde vital pulp therapy, intra-orifice barrier placement and the management of external cervical resorption, Additionally, various studies have highlighted its favourable soft tissue compatibility, sealing ability (even in moist environments) as well as its acceptable mechanical properties. However, certain limitations, including reduced flexural strength and higher cytotoxicity compared to calcium silicate-based materials, such as mineral trioxide aggregate, have been reported.

Conclusion: Geristore® presents as a clinically useful alternative for specific endodontic indications where biocompatibility, sealability, and ease of handling seem critical. However, further high-quality clinical trials and comparative studies are essential to validate its long-term performance and establish its role relative to established endodontic biomaterials.
