Aim: To evaluate the apical seal and the quality of root filling in canals instrumented with Reciproc in relation to canal filling technique and post insertion.
Methodology: Fluid filtration test and microtomographic scan were performed on 44 extracted teeth instrumented with Reciproc R40 and divided into four test groups (n = 10): G1, single cone; G2, as G1 + post; G3, System B; G4, as G3 + post (parametric and non-parametric tests, p < 0.05). Results: High percentages of canal filling were registered in all groups. In G3 the volume of internal voids and microleakage were greater than G4 (p < 0.05) and G1, G2 e G4 (p < 0.05), respectively.
Conclusions: Our results support the use of simplified integrated endodontic techniques of instrumentation, filling and reconstruction.
