Effect of calcium hypochlorite and sodium thiosulfate on the bond strength to pulp chamber dentin: A laboratory investigation

This study compared the effects of sodium hypochlorite (NaOCl) and calcium hypochlorite (Ca(OCl)2) on the bond strength to pulp chamber dentin, with and without the use of sodium thiosulfate (Na2S2O3). Fifty human molars were divided into five groups, each treated with different immersion protocols. The results showed that NaOCl had the lowest bond strength, while Ca(OCl)2 had similar bond strength to the control group treated with sodium chloride (NaCl). The use of Na2S2O3 increased the bond strength after NaOCl treatment but had no effect after Ca(OCl)2 treatment. Dentin treated with Ca(OCl)2 had a higher Ca/P ratio and showed bond strength comparable to NaCl-treated dentin.
