Resumen
The effect of Candida albicans biofilms and methyl methacrylate (MMA) pretreatment on the bond strength between soft denture liners and polymethyl methacrylate (PMMA) resin was analyzed. Specimens were prepared and randomly divided with respect to PMMA pretreatment, soft liner type (silicone-based or PMMA-based), and presence or absence of a C. albicans biofilm. Samples were composed of a soft denture liner bonded between two PMMA bars. Specimens (n = 10) were incubated to produce a C. albicans biofilm or stored in sterile PBS for 12 days. The tensile bond strength test was performed and failure type was determined using a stereomicroscope. Surface roughness (SR) and scanning electron microscopy (SEM) analysis were performed on denture liners (n = 8). Highest bond strength was observed in samples containing a silicone-based soft liner and stored in PBS, regardless of pretreatment (p < 0.01). Silicone-based specimens mostly underwent adhesive failures, while samples containing PMMA-based liners predominantly underwent cohesive failures. The silicone-based specimens SR decreased after 12 days of biofilm accumulation or PBS storage, while the SR of PMMAbased soft liners increased (p < 0.01). The PMMA-based soft liners surfaces presented sharp valleys and depressions, while silicone-based specimens surfaces exhibited more gentle features. In vitro exposure to C. albicans biofilms reduced the adhesion of denture liners to PMMA resin, and MMA pretreatment is recommended during relining procedures. 28 1 61 66 Pisani, M.X., Malheiros-Segundo, A.L., Balbino, K.L., Souza, R.F., Paranhos, H.F., Silva, C.H., Oral health related quality of life of edentulous patients after denture relining with a silicone-based soft liner (2012) Gerodontology., 29 (2), pp. 474-480. , Jun Mutluay, M.M., Oguz, S., Fløystrand, F., Saxegaard, E., Dogan, A., Bek, B., A prospective study on the clinical performance of polysiloxane soft liners: one-year results (2008) Dent Mater J., 27 (3), pp. 440-447. , May Monsenego, P., Presence of microorganisms on the fitting denture complete surface: study 'in vivo' (2000) J Oral Rehabil., 27 (8), pp. 708-713. , Aug Uludamar, A., Özyesil, A.G., Ozkan, Y.K., Clinical and microbiological efficacy of three different treatment methods in the management of denture stomatitis (2011) Gerodontology., 28 (2), pp. 104-110. , Jun Rinastiti, M., Özcan, M., Siswomihardjo, W., Busscher, H.J., van der Mei, H.C., Effect of biofilm on the repair bond strengths of composites (2010) J Dent Res., 89 (12), pp. 1476-1481. , Dec Leles, C.R., Machado, A.L., Vergani, C.E., Giampaolo, E.T., Pavarina, A.C., Bonding strength between a hard chairside reline resin and a denture base material as influenced by surface treatment (2001) J Oral Rehabil., 28 (12), pp. 1153-1157. , Dec Saraç, Y.S., Basoglu, T., Ceylan, G.K., Saraç, D., Yapici, O., Effect of denture base surface pretreatment on microleakage of a siliconebased resilient liner (2004) J Prosthet Dent., 92 (3), pp. 283-287. , Sep Sarac, D., Sarac, Y.S., Basoglu, T., Yapici, O., Yuzbasioglu, E., The evaluation of microleakage and bond strength of a siliconebased resilient liner following denture base surface pretreatment (2006) J Prosthet Dent., 95 (2), pp. 143-151. , Feb Tugut, F., Akin, H., Mutaf, B., Akin, G.E., Ozdemir, A.K., Strength of the bond between a silicone lining material and denture resin after Er:YAG laser treatments with different pulse durations and levels of energy (2012) Lasers Med Sci., 27 (2), pp. 281-285. , Mar Al-Athel, M., Jagger, R., Jagger, D., Effect of ageing on the bond strength of a permanent denture soft lining material (2002) J Oral Rehabil., 29 (10), pp. 992-996. , Oct Takahashi, J.M., Consani, R.L., Henriques, G.E., Nóbilo, M.A., Mesquita, M.F., Effect of accelerated aging on permanent deformation and tensile bond strength of autopolymerizing soft denture liners (2011) J Prosthodont., 20 (3), pp. 200-204. , Apr Senna, P.M., Silva, W.J., Faot, F., Del Bel Cury, A.A., Microwave disinfection: cumulative effect of different power levels on physical properties of denture base resins (2011) J Prosthodont., 20 (8), pp. 606-612. , Dec Minami, H., Suzuki, S., Ohashi, H., Kurashige, H., Tanaka, T., Effect of surface treatment on the bonding of an autopolymerizing soft denture liner to a denture base resin (2004) Int J Prosthodont., 17 (3), pp. 297-301. , May-Jun Maeda, T., Hong, G., Sadamori, S., Hamada, T., Akagawa, Y., Durability of peel bond of resilient denture liners to acrylic denture base resin (2012) J Prosthodont Res., 56 (2), pp. 136-141. , Apr Gonçalves, L.M., Del Bel Cury, A.A., Sartoratto, A., Garcia Rehder, V.L., Silva, W.J., Effects of undecylenic acid released from denture liner on Candida biofilms (2012) J Dent Res., 91 (10), pp. 985-989. , Oct Pinto, J.R., Mesquita, M.F., Henriques, G.E., Nóbilo, M.A.A., Effect of thermocycling on bond strength and elasticity of 4 long-term soft denture liners (2002) J Prosthet Dent., 88 (5), pp. 516-521. , Nov Mutluay, M.M., Ruyter, I.E., Evaluation of bond strength of soft relining materials to denture base polymers (2007) Dent Mater., 23 (11), pp. 1373-1381. , Nov Rached, R.N., Del Bel Cury, A.A., Heat-cured acrylic resin repaired with microwave-cured one: bond strength and surface texture (2001) J Oral Rehabil., 28 (4), pp. 370-375. , Apr Akin, H., Tugut, F., Guney, U., Kirmali, O., Akar, T., Tensile bond strength of silicone-based soft denture liner to two chemically different denture base resins after various surface treatments (2013) Lasers Med Sci., 28 (1), pp. 119-123. , Jan Bulad, K., Taylor, R.L., Verran, J., McCord, J.F., Colonization and penetration of denture soft lining materials by Candida albicans (2004) Dent Mater., 20 (2), pp. 167-175. , Feb Rodger, G., Taylor, R.L., Pearson, G.J., Verran, J., In vitro colonization of an experimental silicone by Candida albicans (2010) J Biomed Mater Res B Appl Biomater., 92 (1), pp. 226-235. , Jan Nikawa, H., Jin, C., Hamada, T., Makihira, S., Kumagai, H., Murata, H., Interactions between thermal cycled resilient denture lining materials, salivary and serum pellicles and Candida albicans in vitro.
