Handling time of self-etching adhesives vs. etch and rinse adhesives

Introduction: The aim of this study was to test handling time necessary to complete restoration using several different adhesive systems, etch and rinse and self-etching in terms of manipulation time in paediatric dentistry clinical practice. Material and Methods: Tested self-etching adhesive systems were AdheSe (Ivoclar/Vivadent, Lot G2718), Clearfil SE Bond (Kuraray Dental, Lot 4194), Clearfil S3 Bond (Kuraray Dental, Lot 41120), Adhese One Vivapen (Ivoclar/Vivadent, Lot K10655), Unifil Bond (GC, Lot 0406021), Futura Bond NR (Voco, Lot 581031) and Adper Prompt-L-Pop (3M Espe, Lot 223261). Etch and rinse tested systems were Single Bond (3M Espe, Lot 6FN) and Excite (Ivoclar/ Vivadent, Lot J14884). Restorations were made with composite Tetric (Ivoclar/Vivadent, Lot E 46159) according to manufacturers instructions as cylinders of the material. Each cylinder was adhered to enamel with the tested adhesive system. Time necessary to complete each restoration was measured. Statistical analysis was performed using Anova and Tukey HSD test. Results: The score measured produced statistical significance and confirmed difference among tested adhesives (p<0, 01). Significantly better time was measured for Prompt-L-Pop (78, 7 s), AdheSe One Vivapen (82, 7 s) and Clearfil S3 (92, 4 s) than Excite (115, 8 s) and Single Bond (116, 7 s). All other tested self-etching systems did not produce statistically significant difference compared to tested etch and rinse systems. Conclusion: Handling properties of the “all in one” self etching systems are less time consuming because of the easier manipulation and faster application and thus easier to use in paediatric dentistry clinical practice
