Abstract
The direct restoration technique is the most used to treat the sequelae of dental caries. With the constant evolution of dental materials, emerged in the dental market Cention n (Ivoclar Vivadent), material belonging to the group of alkasite materials. This material has as proposal a higher mechanical resistance than the composite resin, with the similar color to the tooth and with good marginal sealing power. The present study aimed to compare the marginal infiltration of enamel in restorations using Cention n (Ivoclar Vivadent) with and without the use of adhesive and composite resin. Twenty one cavities were performed on the buccal surface of seven bovine incisor teeth. The cavities were divided into three groups: Group I - restoration with Cention n (Ivoclar Vivadent) without adhesive; Group II - restoration with Cention n (Ivoclar Vivadent) with adhesive; and Group III - adhesive system and vittra APS (FGM) resin. The collected data were submitted to the Anova statistical test in which the comparison between Groups I and II, II and III, and I and III was performed. In none of the cases a significant difference was found (p <0.05). Despite the limitations of an in vitro study, the results suggest that the marginal sealing of composite resin and alkasite do not differ significantly from each other.
