“…Moreover, the proper restorative techniques and the adequate marginal seal of the restorations prevented the bacterial penetration. The antibacterial and remineralizing ability of Activa Bioactive and Riva Light Cure liners had a crucial role in caries prevention, as well both lining materials showed high bond strength to dentin and resin composite which might prevent secondary caries and microleakage as reported by a previous laboratory study 50 . This finding was in agreement with a clinical trial 56 which stated that both Activa Bioactive and RMGI scored 100% success after 1 year regarding the recurrence of decay.…”

“…This could be attributed to the active ionic resin matrix and shock absorbing rubberized fillers in Activa Bioactive liner which bond chemically to tooth structure and provide sealing against bacterial leakage and thus, reducing sensitivity. Moreover, Activa Bioactive has the ability to release and recharge calcium, phosphate, and fluoride ions provoking the mineral apatite formation and remineralization 50 . This was supported by Hirani et al 51 who reported that there was no postoperative hypersensitivity related to Activa Bioactive material.…”

To evaluate the impact of using ion-releasing liners on the 3-year clinical performance of posterior resin composite restorations after selective caries excavation with polymer burs. 20 patients were enrolled in this trial. Each patient had two deep carious lesions, one on each side of the mouth. After selective caries removal using polymer bur (PolyBur P1, Komet, Brasseler GmbH Co. KG, Lemgo, Germany), cavities were lined with bioactive ionic resin composite (Activa Bioactive Base/Liner, Pulpdent, Watertown, MA, USA) or resin-modified glass ionomer liner (Riva Light Cure, SDI, Bayswater, Victoria, Australia). All cavities were then restored with nanofilled resin composite (Filtek Z350XT, 3M Oral Care, St. Paul, MN, USA). All the tested materials were placed according to the manufacturers’ instructions. Clinical evaluation was accomplished using World Dental Federation (FDI) criteria at baseline and after 6 months, 1, 2, and 3 years. Data were analyzed using Mann–whitney U and Friedman tests (p < 0.05). The success rates were 100% for all resin composite restorations either lined with ion-releasing resin composite or resin-modified glass ionomer liner. Mann–whitney U test revealed that there were no statistically significant differences between both ion-releasing lining material groups for all criteria during the follow-up periods (p > 0.05). Resin composite restorations showed acceptable clinical performance over 3 years either lined with bioactive ionic or resin-modified glass ionomer liners after selective caries excavation preserving pulp vitality. After the 3-year follow-up period, Activa Bioactive and Riva Light Cure liners were clinically effective and they exhibited with the overlying composite restorations successful clinical performance.Trial registration number: NCT05470959. Date of registration: 22/7/2022. Retrospectively registered.

“…There are few reports in the literature about the mechanical properties of these newly launched materials [ 24 , 25 , 26 , 29 , 30 ]. In addition, previous studies reported the effect of treatment with CHX and SDF on the bonding of resin composite to dentin [ 16 , 20 , 31 , 32 , 33 ].…”

Treating dentin surfaces with antibacterial agents prior to bonding bioactive restorations might affect their mechanical properties. In this study, we evaluated the effect of silver diamine fluoride (SDF) and chlorhexidine (CHX) on the shear bond strength (SBS) of bioactive restorative materials. Dentin discs were treated with SDF for 60 s or CHX for 20 s and bonded with four restorative materials, namely Activa Bioactive Restorative (AB), Beautifil II (BF), Fuji II LC (FJ), and Surefil One (SO). Control discs were bonded without treatment (n = 10). SBS was determined using a universal testing machine, and a scanning electron microscope (SEM) was used for the evaluation of the failure mode and the cross-sectional examination of adhesive interfaces. The SBS of each material between different treatments and of the different materials within each treatment were compared via a Kruskal–Wallis test. The SBS of AB and BF was significantly higher than that of FJ and SO in the control and CHX groups (p < 0.01). In the latter, SBS was higher in FJ than SO (p < 0.01). SO had a higher value with SDF compared to CHX (p = 0.01). The SBS of SDF-treated FJ was higher than that of the control (p < 0.01). SEM showed a more homogenous and improved interface of FJ and SO with SDF. Neither CHX nor SDF compromised the dentin bonding of bioactive restorative materials.
