Treatment of Gingival Recession Associated with Non-Carious Cervical Lesions Using Resin Modified Glass Ionomer Cement with Connective Tissue Graft a Randomized Controlled Clinical Trial

Introduction: Gingival recession (GR) is a common aesthetic problem associated with the cervical wear of the tooth structure and dentin hypersensitivity. Recently, periodontal-restorative approaches have been proposed for the management of GR associated with non-carious cervical lesions (NCCLs), which has proven effective. The present study aimed to evaluate this method.  Methods: In total, 30 subjects with isolated Millers class I GR associated with NCCL in the maxillary canines and premolars were randomly assigned to group A (CTG) and group B (R+CTG). Clinical parameters, including the probing pocket depth (PPD), relative GR (RGR), keratinized tissue width (KTW), keratinized tissue thickness (KTT), relative clinical attachment level (CAL), cervical lesion height (CLH), and dentin hypersensitivity (DH), were recorded at baseline (BL) and after one and six months. In addition, maximum root coverage (MRC) was evaluated after six months.  Results: In both groups, a statistically significant reduction was observed in the PPD, RGR, and CLH after six months (P=0.001). On the other hand, a significant increase was observed in the KTW, KTT, and CAL in both groups (P=0.001). Moreover, the visual analogue pain scores indicated a significant reduction in both groups, while the reduction was considered more significant in group B (P˂0.05) compared to group A. In groups A and B, 69.24% and 61.54% of the sites showed MRC, respectively. Conclusion: According to the results, both groups achieved comparable root coverage, while the presence of restoration led to a greater reduction in dentin hypersensitivity.
