Caries Around Restorations and Marginal Adaptation of ion-Releasing Materials vs Resin Composite: a Systematic Review and Meta-Analysis of Randomized Clinical Trials

Objectives: This systematic review was aimed to evaluate the incidence of caries around restorations and marginal adaptation in different categories of ion-releasing materials restorations in comparison with resin composite.
Methods: Electronic search within the following databases (Medline via Pubmed, Scopus) with no date or language restriction was conducted until May 21st. Grey literature was searched using, OGrey and, IADR abstracts from 2010-2020. Randomized clinical trials that compared ion-releasing materials vs resin composite were included. Random-effects meta-analysis with risk difference and 95% CI was used. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. The risk of bias was evaluated using the (ROB.2) tool.

[
Results: Twenty-two studies met the inclusion criteria and 10 studies were included in the meta-analysis, with subgroups based on 3 follow-up periods (1 year, 18 months-2 years, and 3 years). Fifteen studies had a high risk of bias, 3 studies showed an unclear risk of bias, and 3 presented with a low risk of bias. The overall quality of evidence for secondary caries and marginal adaptation outcome measures was low. The results of the meta-analysis demonstrated no significant difference (p > 0.05) in secondary caries incidence and marginal adaptation between ion-releasing materials and resin composite. The overall number of events was low in both groups.
Conclusions: 1. Within the limitation of this work, this systematic review and meta-analysis revealed that secondary caries incidence is not dependent on the ion-releasing capability of the restorative material.
2. Development of secondary caries is more likely influenced by patient and operator factors.
3. Short-term follow-ups are a common denominator among the available body of evidence. Longer follow-ups are recommended to accurately detect the performance of different restorative materials after prolonged clinical service
4. Several new ion-releasing materials lack high-quality clinical reporting and need further investigations.
