Abstract

Aim:

The aim of vital pulp therapy is to preserve the vitality of the pulp by placing biocompatible material over exposed or nearly exposed pulp tissue. The shear bond strength (SBS) between the liner material and the final restoration significantly influences the success of this approach. This systematic review and meta-analysis were conducted to compare and evaluate the SBS of composite and glass-incorporated restorations with calcium silicate-based cement as the liner.

Materials and Methods:

A thorough literature search was performed across multiple electronic databases, including PubMed, Scopus, EBSCOhost, Google Scholar, and Sicelo, using a combination of Medical Subject Headings terms and relevant keywords. Only in vitro studies published in English up to March 2025 were considered. The review focused on studies assessing the SBS of restorations (composite and glass-based) using calcium silicate-based liners such as mineral trioxide aggregate, Biodentine, TheraCal LC (Light Cure), and calcium-enriched mixture (CEM) cement. Risk of bias was evaluated using the Quality Assessment Tool For In Vitro Studies (QUIN) tool. Eligible studies were subjected to quantitative synthesis through meta-analysis.

Results:

Sixteen studies were selected based on eligibility criteria. Among these, 15 exhibited medium risk of bias, while one showed a low risk. All 16 studies were incorporated into the meta-analysis. The majority of the included studies demonstrated that composite restorations exhibited superior SBS compared to glass-incorporated.

Conclusion:

Current evidence suggests that composite restorations paired with calcium silicate-based liners provide a higher SBS compared to glass ionomer-containing restorations. Among these, Biodentine stands out as the most effective liner, thanks to its chemical and physical properties that improve bonding performance.
