Background: In the clinical setting, restoring cervical margins proves challenging as these areas are prone to issues such as microleakage, cavo-surface stains, and postoperative sensitivity.Activa Bioactive Restorative represents a promising advancement in dental restorative materials, designed to replicate the natural properties of tooth structure. Despite its potential, concerns persist regarding the susceptibility of this material to microleakage, a phenomenon that can lead to secondary caries. Microleakage is a crucial parameter to assess the sealing ability of dental materials, impacting the longevity and effectiveness of restorations. This study addresses the need for a comprehensive understanding of microleakage associated with Activa Bioactive Restorative and explores the potential improvement through the application of a bonding agent. Aim: The aim of this study is to assess and compare microleakage in non-carious cervical lesions that have been restored using Activa Bioactive Restorative, both with and without the application of a bonding agent. Methodology: Fifty class V cavities were created in extracted teeth and then randomly allocated into two groups. In Group 1 (n=25), Activa Bioactive was applied without a bonding agent, whereas in Group 2 (n=25), Activa Bioactive Restorative was used along with a bonding agent.After the curing phase, all samples were subjected to both thermocycling and repeated loading cycles.The application of 2% Rhodamine B dye was conducted for staining, followed by an assessment of dye penetration in the specimens. Results: Statistical analysis, utilizing the unpaired t-test, provided results that indicated significant differences between the two groups. Activa Bioactive Restorative in combination with a bonding agent demonstrated reduced microleakage compared to the group without the bonding agent. In addition, further investigation is warranted regarding implications of restorative dental procedures to more general health concerns, possible associations between restorative dental procedures and temporomandibular disorders (TMD) and tinnitus. Conclusion: In the context of non-carious cervical lesions, Activa Bioactive Restorative, when used in conjunction with a bonding agent, exhibited superior performance by minimizing microleakage. This finding emphasizes the potential benefits of incorporating a bonding agent in the restoration of such lesions.
