PREPaRation with RECiPRoC® Tried and tested – Millions of treatments have been performed with RECiPRoC® since its introduction in 2011. one file endo, the innovative concept for root canal preparation is growing worldwide. Renowned scientists have put the RECiPRoC® system to the test and have come to the following conclusion:

RECiPRoC® is safe, efficient and time saving.

Dr. Bjørn Besserman-svendsen, Frederiksberg Copenhagen, Denmark

“My experience with RECiPRoC® has been nothing short of amazing. this presents a paradigm shift in the way mechanical root canal preparation can be achieved to provide every practitioner a markedly better opportunity to produce consistent, predic- table results. RECiPRoC® provides the safest and easiest method for shaping the canals compared to any system. if this doesn’t get you more excited about endodontics nothing will!“

Compared to another single file system, the RECiPRoC® instrument showed a significantly higher resistance to cyclic fatigue (time period until fracture: RECiPRoC® 130.8 seconds versus single file system 97.8 seconds).4

HOw saFE Is RECIPROC®?

Canal shaping

Resistance to fracture

one reason for instrument fracture is cyclic fatigue which is caused by the repeated tension and compression of the instrument, for example in a canal curvature.

the RECiPRoC® instrument maintains the original root canal curvature well.2

the RECiPRoC® R25 in reciprocation has a signi- ficantly higher resistance to cyclic fatigue than in continuous rotation.3

the RECiPRoC® instrument causes significantly less microcracks compared to another single and multiple file system.6

microcracks

numerous tests show that endodontic procedures may cause undesirable mechanical damages in dentine.5

Extrusion

after preparation with RECiPRoC®, the degree of inflammation (e.g. Substance P values) in the perio- dontal ligament is almost identical to that of a healthy, untreated tooth.7

no significant inflammatory reaction in the apical region due to the extrusion of debris during preparation with RECiPRoC®.8

RECiPRoC® cleans the root canal system significantly more thoroughly, especially in the apical region, com- pared with other systems.9

RECiPRoC®’s ability to signi- ficantly reduce the amount of bacteria in oval canals is equivalent to that of a multiple file system.10
