New approaches in restorative materials were focused on the development of self-adhesive, dual-cured restorative materials that can be placed in bulk to simplify the placement of posterior restorations and have caries-protecting properties. The self-cure option leads to better depth of cure and these materials also have bioactive characteristics such as leaching remineralizing ions.Although several The only clinical trial published on the clinical performance of CN was in the restoration of non-carious cervical lesions by comparing it with a RMGIC.In the present study, CN showed similar retention rate with the RC in 1-year follow-up. However, the marginal adaptation scores of CN significantly worsened after 6 months and RC showed statistically higher alpha scores than CN. On the other hand, the bravo scores of both groups were similar after one year.After removing caries lesions in the proximal surfaces, the environment becomes less cariogenic, affecting the neighboring tooth as well. The ion-leaching restorative material can help to reduce bacterial growth and promote the formation of fluorohydroxyapatite in proximal caries lesions.Posterior RCs are desired by patients for esthetic reasons and preferred by the dentists for their advantages such as the superior protection of hard tissues with a conservative cavity preparation and cheaper price compared to porcelain restorations. Bulk-fill RCs have been used very often recently for their short application time and ensured deep polymerization.The introduction of alkasite-based restorative material was connected with the hope of replacing amalgam. Therefore, CN could be a more reliable restorative material in minimal intervention oral care based adhesive systems. To improve its mechanical properties, several attempts are still underway. Recently, a manageable self-mixing capsule has been developed for reassessment of the material properties; however, opportunities for improvement are still existing.This study has some limitations that must be considered. Firstly, the short evaluation period. This study is a preliminary report and the evaluation period is not long enough. However, no clinical data on this material has been available to date. Therefore, studies examining the restoration of Class II cavities with longer follow-ups are needed. Secondly, this study included individuals with healthy periodontal tissues and, thus, studies with different participants should be performed in the future.Lastly, in this study, cotton rolls were used for isolation to imitate clinical conditions.
