Clinical comparison of sealant and bonding systems in the restoration of fractured anterior teeth.
This study compared the clinical performance of the ultraviolet light-initiated fissure sealant and composite system (Nuva-Seal/Nuva-Fil) with a chemically activated system (Adaptic Bonding Agent/Adaptic). A total of 63 fractured permanent anterior teeth involving only enamel and dentin were restored. All teeth were isolated with rubber dams, and the acid etch technique was used. The degree of success was determined from an assessment of retention, marginal integrity, marginal staining, and color change. The restorations were evaluated at 3, 6, 12, 18, and 24 months postoperatively. Of the restorations, 93% were retained in both groups of patients after two years. Varying degrees of marginal problems (lack of marginal integrity or marginal staining) were directly attributable to the extension of the bonding medium and the composite in relation to the conditioned enamel and to each other. Repolishing of the margins should be considered at the time of the recall appointments to improve the quality of restoration.
