Abstract
Introduction: Despite these excellent properties, GIC(Glass ionomer cements ) also possesses several undesirable characteristics such as long setting time, difficulties in manipulation and insertion, high costs, and potential of discoloration. In order to overcome these limitations, various alternative formulations have been developed. Aim: To compare and evaluate the root reinforcement potential of four different intraorifice barriers: resin-modified glass ionomer cement (RMGIC), and Glass ionomer cements,(GIC) Materials and Methods: The treatment records of patients who had undergone treatment in Saveetha Dental College between 2019 to 2021 were assessed for this study. The extracted data was tabulated in a spreadsheet (Excel 2017: Microsoft Office) and analysed using SPSS 19.0 version software (SPSS, Inc., Chicago). Descriptive statistics and chi-square tests were performed with the level of significance at 5% (P<0.05). Conclusion: Future development of the conventional bleaching agents by the addition of radical scavengers such as thiocarbamide or using sodium per carbonate is promising in terms of minimal penetration of hydrogen into the periodontal space.
