Effect of Superoxidized Water and Sodium Hypochlorite, Associated or Not with EDTA, on Organic and Inorganic Components of Bovine Root Dentin

摘要: Abstract Introduction This study aimed to evaluate the effects of Sterilox (Sx), a superoxidized water, 5% and 2% sodium hypochlorite (5NaOCl 2NaOCl), 17% EDTA (E) on organic inorganic components bovine dentin. Methods Eighty incisors were randomly divided into 8 groups ( n = 10): 5NaOCl, 5NaOCl + E, 2NaOCl, 2NaOCl Sx, Sx E alone, distilled water (H 2 O). Root canal instrumentation was performed by using corresponding irrigant. The apical 15 mm longitudinally sectioned fragments, one for light microscopy analysis in slides stained with picrosirius red (organic component) other scanning electron (inorganic component). Scores data obtained submitted Kruskal-Wallis test, followed multiple comparisons test P Results chemical solution had greater effect component dentin area depth than 2NaOCl. solutions caused greatest change collagenous matrix near root lumen. showed similar behavior associated or not promoting more superficial disorganization collagen smaller area. Demineralization observed all which used. However, areas erosion open dentinal tubules detected only when it combined NaOCl. Conclusions Five percent NaOCl promoted most extensive damage dentin, EDTA, could be seen. Considering these specific aspects, milder
