Objectives: To evaluate and compare the clinical outcome of the treatment of gingival recession associated with non-carious cervical lesions by a coronally advanced flap with glass ionomer restoration (CAF+R) versus coronally advanced flap (CAF) alone. Methodology: 40 sites from selected subjects having bilateral Miller’s class-I or II gingival recession associated with non-carious cervical lesion (NCCL), were grouped as Site-A (treated with CAF+R) and Site-B (treated with CAF). The clinical parameters assessed at baseline, 1 month, 3 months and 6 months post-operatively were: relative gingival recession, height of the non-carious cervical lesion on the root surface, keratinised tissue width and root coverage. Results: Data obtained was analysed using paired and unpaired t test and repeated measures ANOVA. On intergroup comparison, mean change in relative gingival recession and height of the NCCL on the root surface, from baseline to 1 month, baseline to 3 months and baseline to 6 months was greater at site-A as compared to site-B. However, these differences were statistically nonsignificant (p>0.05). The change in keratinised tissue width from baseline to 6 months was greater at site-B as compared to site-A, but this difference was statistically nonsignificant (p=0.514). The mean root coverage at site-A (84.91 ± 4.58%) as compared to site-B (90.72 ± 2.58%) was statistically significant (p<0.001). Conclusion: Coronally advanced flap with glass ionomer restoration was as effective as coronally advanced flap alone for the treatment of gingival recession associated with NCCLs.
