Clinical evaluation of Cention–N and nano hybrid composite resin as a restoration of non-carious cervical lesion

Introduction: Non carious cervical lesion, (NCCL) is the loss of tooth structure at the cemento enamel junction, or CEJ level that is unrelated to dental caries. These lesions can affect plaque retention, tooth sensitivity, structural integrity, caries incidence, and pulpal vitality. Objectives: To compare clinical effectiveness of Cention–N and Nanohybrid composite resin as a restoration of non-carious cervical lesion for gross fracture, marginal integrity & surface texture. Materials and Methods: Total 24 patients having two class V non-carious cervical lesion in the same arch, approximately of same size and shape were selected. Entire study was carried out by two operators. Both teeth were restored, finished and polished by one operator with Cention–N and Tetric N Ceram (Ivoclar – Vivadent) respectively. Evaluation for marginal integrity & surface texture was done by second operator on the same day of restoration. (USPHS, Ryge criteria for direct clinical evaluation). Follow up was done for gross fracture, marginal integrity & surface texture after 1 week, 1 month, 3 month & 6 month. All the data were collected according to USPHS, Ryge Criteria. Statistical analysis was done by chi square test. Results: Cention–N is as effective as Tetric-N-Ceram for gross fracture and marginal integrity till 6 months. But Cention–N showed inferior surface characteristics than Tetric-N-Ceram after 1 week. Conclusion: Cention – N is as effective as Tetric N Ceram for gross fracture and marginal integrity but Cention – N has an inferior surface characteristics than Tetric N Ceram.
