Resumen
This study investigated the effect of the incorporation of an iodonium salt in experimental composites, on the bond strength of metallic brackets bonded to bovine teeth. Two hundred and seventy bovine teeth were embedded in self-curing acrylic resin and divided into 18 groups (n=15), according to the experimental composite with an iodonium salt at molar concentrations 0 (control), 0.5, or 1%; the light-activation times (8, 20 and 40 s); and the storage times (10 min or 24 h). Metallic brackets were fixed on the tooth surface using experimental composites. Photoactivation was performed with a quartz-tungsten-halogen light-curing unit curing unit for 8, 20 and 40 s. The specimens were stored in distilled water at 37 °C for 10 min or 24 h and submitted to bond strength test at 0.5 mm/min. The data were subjected to three-way ANOVA and Tukey’s test (α=0.05). The Adhesive Remnant Index (ARI) was used to classify the failure modes. The shear bond strengths (MPa) at 10 min for light-activation times of 8, 20 and 40 s were: G1 - 4.6, 6.9 and 7.1; G2 - 8.1, 9.2 and 9.9; G3 - 9.1, 10.4 and 10.7; and at 24 h were: G1 - 10.9, 11.1 and 11.7; G2 - 11.8, 12.7 and 14.2; G3 - 12.1, 14.4 and 15.8. There was a predominance of ARI score 3 for groups with 10 min storage time, and ARI score 2 for groups with 24 h storage time. In conclusion, the addition of iodonium salt (C05 and C1) to the experimental composite may increase the bond strength of brackets to bovine enamel using reduced light exposure times. 25 3 237 240 Romano, F.L., Correr, A.B., Correr-Sobrinho, L., Magnani, M.B., Ruellas, A.C., Clinical evaluation of the failure rates of metallic brackets (2012) J Appl Oral Sci, 20, pp. 228-234 Costa, A.R., Correr, A.B., Puppin-Rontani, R.M., Vedovello, S.A., Valdrighi, H.C., Correr-Sobrinho, L., Effects of thermocycling and light source on the bond strength of metallic brackets to bovine teeth (2011) Braz Dent J, 22, pp. 486-489 Correr, A.B., Costa, A.R., Lucato, A.S., Vedovello, S.A., Valdrighi, H.C., Vedovello Filho, M., Correr-Sobrinho, L., Effect of activation mode on shear bond strength of metallic brackets (2013) Braz Dent J, 24, pp. 513-516 Sfondrini, M.F., Cacciafesta, V., Scribante, A., Klersy, C., Plasma arc versus halogen light curing of orthodontic brackets: A 12-month clinical study of bond failures (2004) Am J Orthod Dentofacial Orthop, 125, pp. 342-347 Staudt, C.B., Krejci, I., Mavropoulos, A., Bracket bond strength dependence on light power density (2006) J Dent, 34, pp. 498-502 Rueggeberg, F., Contemporary issues in photocuring (1999) Compend Contin Educ Dent Suppl, 25, pp. 4-15 Stansbury, J.W., Curing dental resins and composites by photopolymerization (2000) J Esthetic Dent, 12, pp. 300-308 Sfondrini, M.F., Cacciafesta, V., Pistorio, A., Sfondrini, G., Effects of conventional and high-intensity light-curing on enamel shear bond strength of composite resin and resin-modified glass-ionomer (2001) Am J Orthod Dentofacial Orthop, 119, pp. 30-35 Costa, A.R., Vedovello-Filho, M., Correr, A.B., Vedovello, S.A.S., Puppin-Rontani, R.M., Ogliari, F.A., Bonding orthodontics brackets to enamel using experimental composites with an iodonium salt (2014) Eur J Orthod, 36, pp. 297-302 Oesterle, L.J., Newman, S.M., Shellhart, W.C., Rapid curing of bonding composite with a xenon plasma arc light (2001) Am J Orthod Dentofacial Orthop, 119, pp. 610-616 Staudt, C.B., Mavropoulos, A., Bouillaguet, S., Kiliaridis, S., Krejci, I., Lightcuring time reduction with a new high-power halogen lamp (2005) Am J Orthod Dentofacial Orthop, 128, pp. 749-754 Gonçalves, P.R., Moraes, R.R., Costa, A.R., Correr, A.B., Nouer, P.R., Sinhoreti, M.A., Effect of etching time and light source on the bond strength of metallic brackets to ceramic (2011) Braz Dent J, 22, pp. 245-248 Talbot, T.Q., Blankenau, R.J., Zobitz, M.E., Weaver, A.L., Lohse, C.M., Rebellato, J., Effect of argon laser irradiation on shear bond strength of orthodontic brackets: An in vitro study (2000) Am J Orthod Dentofacial Orthop, 118, pp. 274-279 Klocke, A., Korbmacher, H.M., Huck, L.G., Kahl-Nieke, B., Plasma arc curing lights for orthodontic bonding (2002) Am J Orthod Dentofacial Orthop, 122, pp. 643-648 Ogliari, F.A., Ely, C., Petzhold, C.L., Demarco, F.F., Piva, E., Onium salt improves the polymerization kinetics in an experimental dental adhesive resin (2007) J Dent, 35, pp. 583-587 Odian, G., Introduction Principles of Polymerization, 4Th Edition, p. 2004. , John Wiley & Sons, Inc.: Hoboken, USA Bishara, S.E., Von Wald, L., Olsen, M.E., Laffoon, J.F., Effect of time on the shear bond strength of glass ionomer and composite orthodontic adhesives (1999) Am J Orthod Dentofacial Orthop, 116, pp. 616-620 Oliveira, A.S., Barwaldt, C.K., Bublitz, L.S., Moraes, R.R., Impact of bracket displacement or rotation during bonding and time of removal of excess adhesive on the bracket-enamel bond strength (2014) J Orthod, 41, pp. 124-127 Gonçalves, L.S., Moraes, R.R., Ogliari, F.A., Boaro, L., Braga, R.R., Consani, S., Improved polymerization efficiency of methacrylate-based cements containing an iodonium salt (2013) Dent Mater, 29, pp. 1251-1255 Artun, J., Bergland, S., Clinical trials with crystal growth conditioning as an alternative to acid-etch enamel pretreatment (1984) Am J Orthod, 85, pp. 333-340 Kim, D., Stansbury, J.W., Kinetic pathway investigations of three component photoinitiator systems for visible-light activated free radical polymerizations (2009) J Polymer Science Part A: Polymer Chemistry, 47, pp. 887-898 Padon, K.S., Scranton, A.B., A mechanistic investigation of a three component radical photoinitiator system comprising methylene blue, n-methyldiethanolamine, and diphenyliodonium chloride (2000) Journal of Polymer Science Part A: Polymer Chemistry, 38, pp. 2057-2066 Leung, R.L., Fan, P.L., Johnston, W.M., Post-irradiation polymerization of visible light-activated composite resin (1983) J Dent Res, 62, pp. 363-365 Burtscher, P., Stability of radicals in cured composite materials (1993) Dent Mater, 9, pp. 218-221 Mohamad, D., Young, R.J., Mann, A.B., Watts, D.C., Postpolymerization of dental resin composite evaluated with nanoindentation and micro-raman spectroscopy (2007) Arch Orofacial Scienc, 2, pp. 26-31
