Marginal adaptation and post-operative sensitivity in non-carious cervical lesions using a universal adhesive in a Nigerian population

BACKGROUND: Problems such as microleakage and post-operative sensitivity may arise in the composite restoration of non-carious cervical lesions (NCCLs). This study assessed marginal adaptation and post-operative sensitivity in restored non-carious cervical lesions using a universal adhesive with different application techniques.MATERIALS AND METHODS: An interventional study included sixty teeth that met the selection criteria. Total-etch and selective-etch were the two application techniques used. Marginal adaptation and post-operative sensitivity were evaluated immediately post-op as a baseline, then at 3, 6, and 12 months using FDI Criteria. Data collected was analyzed using SPSS with statistical significance at p≤ 0.05.RESULTS: The majority of participants belonged to the 41-50 years age group. The NCCLs were present more in the maxillary teeth at 43(71.7%). Regarding marginal adaptation, out of the 60 restorations, seven restorations showed small marginal fractures at the 12- month period in both techniques. Restorations in the selective-etch technique group had 100% scores of 1 (no hypersensitivity) in postoperative sensitivity throughout the evaluation periods, whereas there was a score of 2 for minor hypersensitivity of restoration in the totaletch technique.CONCLUSION: The assessment of marginal adaptation and post-operative sensitivity in restored teeth with NCCLs using a universal adhesive with selective etch and total-etch techniques showed good clinical performance over a one-year evaluation.
