[Apical leakage in root canal fillings performed with two types of cement following application of Nd: YAG laser or EDTA solution in the root canal walls].


Marginal apical leakage was evaluated in root canal filling performed with two sorts of cements after applying Nd:YAG laser or an EDTA solution in the root canal walls. Sixty-two human lower premolars had their canals instrumented through mechanical technique. Afterwards the external root surfaces were impermeabilized, except for the foramen. The roots were… (More)
