Aim: Toassessbymicro-computedtomography(mCT)thequalityoffillingsincanalsshapedwith Reciproc considering the effects of filling technique and post insertion.
Methodology: The canals of 60 single-rooted teeth were instrumented with Reciproc R40 and randomly assigned to four groups (n = 15): G1, single point; G2, as G1 + DT Light Post; G3, continuous wave of condensation; G4, as G3 + DT Light Post. The filling voids were quantified by mCT. Data were statistically analysed by non-parametric test ( p < 0.05).
Results: Filling greater than 96% of the entire canal volume was observed in all groups. The volume of internal voids was greater in G3 than in G4 ( p < 0.005).
