Aim is to evaluate effectiveness between circumferential and sectional matrix systems in obtaining optimum proximal contact in class II composite restorations. Review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines and registered in PROSPERO-CRD42024556368. Electronic databases were searched from January 1990 to April 2024 for studies assessing effectiveness of circumferential and sectional matrix systems in obtaining optimum proximal contact in class II composite restorations. Quality assessment or risk of bias assessment of included studies was evaluated using Cochrane risk of bias (ROB) -2 tool for randomized controlled trials (RCT) through its domains using RevMan (review manager) software version. Six studies fulfilled the eligibility criteria and were included in qualitative synthesis. Quality assessment revealed a presence of moderate to low risk of bias. It was observed that that sectional matrix band systems were superior and provided better results as compared to circumferential matrix band systems with regards to parameters assessed. It was observed that sectional matrix band system has been found superior to circumferential matrix band system.
