Influence of three different resin adhesive systems on the bonding effect of fiber post
Objective To evaluate the influence of total acid-etching adhesive system,self acid-etching adhesive system,and self-adhesive resin on the bonding effect for fiber post.Methods From October 2021 to March 2022,82 patients(a total of 122 upper and lower anterior teeth)who underwent anterior teeth fiber post repair in the oral outpatient department of Taizhou Polytechnic College were selected as the research objects.The patients were divided into total acid-etching group(28 cases,40 teeth),self acid-etching group(26 cases,40 teeth)and self-adhesive group(28 cases,42 teeth)according to different resin adhesive systems.The total acid-etching group was received Tetric-N Bond total acid-etching resin adhesive for fiber post bonding,the self acid-etching group was received All-Bond Universal self acid-etching resin adhesive for fiber post bonding,and the self-adhesive group was received Relyx Unicem self-adhesive resin for fiber post bonding.After fiber post bonding,all-ceramic crown restoration was performed.The stability rate of fiber post core and the Pink Esthetic Score(PES)and White Esthetic Score(WES)of all-ceramic crown restorations were compared among the three groups.Results After 6,12 and 18 months of bonding,there was no significant difference in the stability rate of fiber post core between and within the three groups(P>0.05).After 18 months of bonding,there were no significant differences in PES and WES scores among the three groups of all-ceramic crown restorations(P>0.05).Conclusion The bonding effect of the three resin adhesive systems on the fiber post is comparable in the short term,and the long-term effect needs further observation.
