Resin Bulkfill Dual-Cured of Proximal Restoration. Clinical Trial
Condition: Dental Restoration; Dental Caries
MeSH terms: Dental Caries
Study type: Interventional

Summary: 
      Objective: To evaluate the immediate clinical performance using FDI criteria in occlusal and
      proximal lesions restored with dual polymerization bulkfill composite resin.

      Materials and methods: Experimental, clinical, controlled, randomized, double-blind study.
      For the evaluation of Fill-up! (FU) will be clinically compared to the control groups of a
      conventional Tetric N-Ceram (TB) RBK and Filtek z350 (z350) conventional composite resin. The
      adhesive process will be carried out under absolute isolation, of selective etching of 37%
      orthophosphoric acid enamel before applying the respective adhesive according to the
      trademark of the composite resins. The evaluation will be to 30 days, 6, 12, 18 and 24 months
      using the modified FDI criteria of postoperative sensitivity, marginal staining, color,
      marginal adaptation and anatomy, being 1: Excellent, 2: Good, 3: Fair, 4: unsatisfactory and
      5: unacceptable. The non-parametric Kruskal Wallis test and Friedman (95% significance) used
      to compare the criteria.
    

Detailed description: 
      Prior to the removal of carious lesions, the tooth will be first anesthetized. The lesion
      areas will be prepared with a diamond rotary instrument (801G.FG.016, Jota AG Rotary
      Instruments - Switzerland) at high speed and under refrigeration with abundant water. Only
      damaged tissue conservatively removed. The corresponding measurements it recorded with a
      millimeter probe (Hu Friedy®, North Carolina, Chicago, USA). Prior to the insertion of the
      material, the sectional matrix system and the palodent type matrix system and with a wooden
      wedge will be used. The manufacturer's instructions for each brand of composite resin will be
      followed. It conditioned with 37% phosphoric acid only in enamel, wash for twice as long and
      dried. The corresponding adhesive will be used f Single Bond Universal adhesive (3M-Espe, ST.
      Paul, MN, USA) applied for the z350 group, Tetric N-Bond Universal adhesive (Ivoclar Vivadent
      AG, Schaan, Liechtenstein) for TB group and One Coat adhesive (Còltene, Whaladent Inc.) for
      FBK group. In the case of the FBK group, a final layer of Brilliant EverGlow composite resin
      (Còltene, Whaladent inc) will be added. Figure 3 Photopolymerization procedures performed
      using an LED light source with a minimum power of 1,100 mW / cm2 (Bluephase Style, Ivoclar
      Vivadent, AG, Schaan, Liechtenstein). The centric and eccentric occlusal contacts were
      verified and adjusted. For the finishing and polishing of both protocols, flexible discs (3M
      ESPE, St. Paul, USA) and the Enhance system (Dentsply, Petrópolis, RJ, Brazil) were used.
