Gingival Health Around Cervical Carious Lesions Restored with Calcium Silicate-based Cement (Biodentine™) Compared with Glass-ionomer Cement: A Randomized Clinical Trial

Abstract

The study aims to assess the gingival health around cervical lesions restored with calcium silicate-based cement (Biodentine™) compared to treatment with glass-ionomer cement (GIC). A total of 28 healthy subjects with carious lesions on the cervical third of the buccal surfaces of posterior teeth (class V-Black's classification) have participated and were distributed over two equal groups. The participants in each group received one type of the tested cements: Biodentine™ or GIC. The oral hygiene and the gingival health of the restored teeth were evaluated clinically at 1, 3, and 6 month intervals. Comparing clinical parameters of gingival and periodontal tissues adjacent to cervical restorations indicated significant differences. Plaque index (PI) and gingival index (GI) were higher in the Biodentine™ group at 1, 3, and 6 months of evaluation with a significant difference (p < 0.05), a rise in pocket depth has been noticed at 3 and 6 months (p < 005). Gingival recession (GR) did not show any difference between groups (p > 0.05). Moreover, bleeding on probing (BOP) values were higher for Biodentine™ restorations compared with GIC with a significant difference (p < 0.05). Cervical restorations of Biodentine™ were associated with more plaque accumulation with a higher degree of gingival inflammation in comparison with GIC.
