ADAPTATION-ADHESION TO THE PULPAR WALL OF ADHESIVES THROUGT DIFFERENT PROMOTERS TO ADHESION, REMINERALIZED AGENTS AND BACTERIZED AGENTS.

The aim of this work was to evaluate the adaptation-adhesion of a self etching adhesive in deep dentin submitted to different treatment. 20 third human molars were employed that were cut transversally in occlusal crown portion until deep dentin was exposed. The teeth were cut longitudinally in bucco-lingual sence and mesio-distal sence for to obtain 4/4 teeth submitted to different treatment conforming 8 groups: Group 1 conditioning with Phosphoric acid to 34.5% + Futurabond NR as self etching agent (SEA); Group 2: Acid Fluoride Phosphate at 1.23% + SEA; Group 3: Clorhexidine at 2% + SEA; Group 4: Hypochlorite-sodium at 5.25% + SEA; Group 5: MI Paste + SEA; Group 6: Phosphoric acid + Hypochlorite-sodium + SEA; Group 7: Hypochlorite-sodium + Clorhexidine + SEA; Group 8: Hypochlorite-sodium + MI Paste + SEA. The materials were applied following the manufacturers’ instructions. In each surface were applied a layer ± 1mm to composite resin Amaris (VOCO) was applied which was photopolimerized for 40 seconds with LED united. Each 1/4 tooth was cut longitudinally in bucco-lingual sence in seriated form and were polished with rotatory discs. For the processing with Confocal Laser Scanning Microscope (Zeiss CL5 Pascal), the cuts were immersed in Rhodamine B at 1% for 24 hours employing for their evaluation and quantification standarized technique and stacks. Some randomized samples were processed to be observed with SEM to emission field. The values obtained were submitted to variance statistical analysis and Bonferroni test. It was determined that the adaptation-adhesion was: a) Deficient with Clorhexidine, with phosphoric acid + Hypochlorite-sodium and Hypochlorite-sodium + Clorhexidine; b) Intermediated with the application of Acidulated Fluoride Phosphate and with MI Paste; c) Highest with Hypochlorite-sodium and Hypochlorite-sodium + MI Paste. Under the conditions created in this work, the adhesion promoters, the remineralized agents and bacterized agents would act modifiying the adaptation-adhesion degree of the adhesive agents
