(TC35) Evaluating Optimal Disinfection Prior to Obturation: A Review of the Endocator Device

In endodontics, treatment success relies on proper chemo-mechanical preparation, effective root canal debridement and thorough disinfection. Studies have shown a link between remaining biofilm and persistent infections resulting in continued postoperative symptoms or failure of the NSRCT [1,2].

Recently, Adenosine TriPhosphate (ATP), present in all viable cells, microbial and host, has been used to determine the potential cellular load by measuring the ATP level at any time during the NSRCT. The Endocator is an innovative device that can be used during the NSRCT to provide an objective, chairside cursory measurement of ATP levels generated by viable cells within the canal system at the time of sampling. This can be used to infer the latent microbial/host cell content prior to completion of the NSRCT. The Endocator uses a sample of canal fluids and generates a score from 0 to 100 which correlates to the relative ATP levels of the sample at the time the sample was taken. With this information the clinician is able to evaluate the relative thoroughness of disinfection and potentially enhance the outcome of NSRCT.
