Fluoride release potential of bioactive orthodontic adhesive systems

AIM: The aim of this study was to assess the fluoride release potential of bioactive orthodontic adhesive systems of different chemical composition. MATERIALS AND METHODS: Test specimens were three commercial bioactive fluoride- containing adhesives: light-cure Transbond Plus (3M Unitek, USA), Light Bond Paste With Fluoride (LBF) (Reliance Orthodontic Products Inc., USA) and the dual-cure Geristore® adhesive with Tenure® primer (DenMat, USA), and one control non- bioactive adhesive Transbond XT (3M Unitek, USA). The Bluephase Style curing unit (Ivoclar Vivadent, Liechtenstein) was used for illuminating ten specimens of each adhesive system at 1100 mW/cm2 for 10 and 20 seconds in a simulation of the clinical bonding procedure under a metal premolar bracket, totaling 80 samples. Microhardness was assessed by the Vickers method on Leica VMHT MOT (Walter Uhl, Germany) before and after four weeks of immersion in artificial saliva of pH 4.8 at 37°C in a simulation of intraoral conditions in presence of mature dental plaque biofilm. The amount of fluoride release was monitored by a fluoride ion selective electrode on Expandable Ion Analyzer EA 940 (Orion Research, USA). Analysis of variance, the Student-Neuman-Keuls post-hoc test and Pearson correlation were used for statistical analysis. RESULTS: Fluoride release after four weeks is related to both adhesive system type and curing time (p<0.05) and decreases in the following order: Transbond Plus10 > Transbond Plus20 > Geristore-Tenure®10 > Geristore-Tenure®20 > LBF10. > LBF20. Amount of decrease of microhardness in four-weeks of immersion in artificial saliva is related to increased release of fluorides (r=0.651 ; p<0.001). Transbond Plus has got significantly superior white spot lesions preventive potential due to twice higher fluoride ions release in comparison with other bioactive adhesives Geristore-Tenure® and LBF. Microhardness of bioactive Transbond Plus decreases on average for 40%, while its non-bioactive control adhesive system changes its microhardness for only 5%. CONCLUSION: Transbond Plus has superior remineralisation potential in comparison with other tested commercially available bioactive orthodontic adhesives, but its high microhardness changes raises concerns of bond strength properties.
