    • Can an LED-laser hybrid light help to decrease hydrogen peroxide concentration while maintaining effectiveness ... 
      Martín, J.; Ovies, N.; Cisternas, P.; Fernández Godoy, Eduardo; Oliveira, Osmir; De Andrade, M.; Moncada, G.; Vildósola, P. (Institute of Physics Publishing, 2015)
      The aim of this study was to compare the bleaching efficacy of 35% hydrogen peroxide and 15% hydrogen peroxide with nitrogen-doped titanium dioxide catalysed by an LED-laser hybrid light. We studied 70 patients randomized ...
    • Comparison of effectiveness and sensitivity using two in-office bleaching protocols for a 6% hydrogen ... 
      Vildósola Grez, Patricio; Vera, F.; Ramirez, J.; Rencoret, J.; Pretel, H.; Oliveira, Osmir; Tonetto, M.; Martin, J.; Fernandez, E. (Indiana University School of Dentistry, 2017)
      Objective: The aim of this blinded and randomized clinical trial was to compare two application protocols (one 36-minute application vs three 12-minute applications). We then assessed the effectiveness of the bleaching ...
    • Dentin hypersensitivity after teeth bleaching with in-office systems. Randomized clinical trial 
      Martin, Javier; Fernández Godoy, Eduardo; Bahamondes, Valeria; Werner, Andrea; Elphick, Klaus; Oliveira, Osmir; Moncada, Gustavo (2013)
      PURPOSE: To comparatively and prospectively compare in a randomized clinical trial, dentin hypersensitivity after treatment with three in-office bleaching systems, based on hydrogen peroxide at different concentrations, ...
    • Does the Use of a ''walking bleaching'' technique increase bone resorption markers? 
      Bersezio Miranda, Cristian; Vildósola Grez, Patricio; Sáez, M.; Sánchez, F.; Vernal Astudillo, Rolando; Oliveira, Osmir; Jorquera, G.; Basualdo, J.; Loguercio, A.; Fernández Godoy, Eduardo (Indiana University School of Dentistry, 2018)
      Objective: This randomized clinical trial evaluated the effect of 35% hydrogen peroxide in comparison with 37% carbamide peroxide in a nonvital bleaching technique of ‘‘walking bleaching’’ (four sessions of treatment) ...
    • Effectiveness of 6% hydrogen peroxide concentration for tooth bleaching - A double-blind, randomized clinical trial 
      Martín, J.; Vildósola, P.; Bersezio Miranda, Cristian; Herrera, A.; Bortolatto, J.; Saad, J.; Oliveira, Osmir; Fernández Godoy, Eduardo (Elsevier Ltd, 2015)
      Objective The aim of this clinical randomized double-blind split-mouth study was to assess the effectiveness of a 6% hydrogen peroxide with nitrogen-doped titanium dioxide light activated bleaching agent. Method 31 patients ...
    • Long-term performance of refurbished amalgam restorations: 10-year follow-up 
      Moncada, Gustavo; Fernández Godoy, Eduardo; Mena, Katherine; Vildósola Grez, Patricio; Estay, Juan; Oliveira, Osmir; Martin, Javier; Mjör, Ivar; Gordan, Valeria (Quintessence Publishing Co., Ltd, 2016)
      Purpose: This prospective, blinded clinical trial assessed the performance of amalgam restorations that were refurbished, replaced, or not treated. Materials and methods: Twenty-three patients were included, ages 18-80 ...
    • Longevity, esthetic perception, and psychosocial impact of teeth bleaching by low (6%) hydrogen peroxide ... 
      Fernández Godoy, Eduardo; Bersezio Miranda, Cristian; Bottner, J.; Avalos, F.; Godoy, I.; Inda, D.; Vildósola, P.; Saad, J.; Oliveira, Osmir; Martín, J. (Indiana University School of Dentistry, 2017)
      OBJECTIVE: The aim was to evaluate the color longevity after nine months of in-office bleaching with gel (6% hydrogen peroxide), to compare this to a control concentration of 35% in a split-mouth study model, and to assess ...
