[Restorations with composite resin and hybrid materials clinical].
The aim of this study was to analyze the in vivo interface biomaterials--dental hard structures associated techniques applied in the cavities of class II after 3 years.


METHODS
The study was longitudinal clinical type. They restored a total of 90 teeth of class II. Cavity preparation was done by mechanical treatment. Cavity preparation was done by mechanical treatment. Filling cavities was performed using as a substitute enamel composite resin (CR) Filtek Supreme (3MESPE) giomer (G) Beautiful (Shofu) and as a substitute dentinar resin modified glass ionomer (RMGI) Vitremer (3MESPE) and compomer flow (C flow) Dyract Flow (Dentsply De Trey) restorations were divided into 4 groups depending on materials used. Group 1--CR-RMGI-24 restoration, Group 2--G-RMGI 23-restoration, Group 3--G-Cflow 21-restoration, Group 4--CR-C flow 22-restoration. Evaluation was done with restorations: modified Rydge criteria. Statistical data processing was performed with SPSS 10.00, 13.00 setting a threshold of p = 0.05 signified statistical.


RESULTS
Analysis of color criteria that there are significant differences in terms of 24 months for restorations made with composite resin for p = 0.05 (R = 0.368). The 12-month evaluation of marginal coloration was in favor of the restorations made with resin composite Filtek Supreme (3MESPE) score A in 95.65% (44) p = 0037.


CONCLUSIONS
Restorations success depends largely on the nature of the material, the dental composition adjacent wall restoration and by possibility can prevent marginal leakage.
