Abstract:
The chelators are solutions that feature free radicals at the end of their molecules that bind to calcium ions of the molecular complex which are intertwined, securing them with coordinated union called chelation. Chelation is a chemical physical phenomenon by which certain calcium ions are captured from complexes that are part without constitute a chemical union with the chelating substance, but rather a combination. The aim of this study was to evaluate the influence of the solutions chelators: EDTA, citric acid and teraclean on adhesive strength of pins fiberglass to root dentin. Were selected forty human lower premolars, accessed the channel, odontometry and preparation of the third cervical with Gates-Glidden drills. The specimens were included in acrylic resin, then instrumented with Universal Protaper rotational system and irrigated with 2.5% sodium hypochlorite. Later, the bodies of proof were randomly divided into 4 groups (n:10), using as final irrigation, chelating solutions: G1:17% EDTA, G2: citric acid 10%, G3: Tetraclean and G4: saline solution. The channels were dried, closed and specimens stored for 30 days in distilled water (kept at 36.5° C and 100% relative humidity). The disfilling has been performed to stay 4mm material plug in the apical region. Fiberglass pins, previously selected, were cemented with ED Primer adhesive system and resin cement Panavia F then the samples were stored for 24 hours at 37° C. The specimens were subjected to tensile test (Emic DL2000) with constant speed of 1 mm/min with 2000 Kgf. The results were submitted to Biostat Program 4.0, descriptive analysis and ANOVA test (p = 0.7428). There was no statistically significant diferences (p > 0.05) between the studied grupos. It was concluded that the type of chelation solution used in irrigation end did not influence retention micromechanics of fiberglass.
