The Endocator® is the first and only chairside device that detects residual contamination invisible to microscopes and radiographs, delivering an adjunctive canal score in 10 seconds. * 1, 2, 3
Know if the root canal is clean
Residual debris is known to contribute to root canal failure. The Endocator® is able to detect trace amounts of root canal contamination from bacteria, nerve tissue, blood, saliva, and apical fluid.
The 0 -100 Endoscore is based on a soon to be published 1000 patient study from the Sibar Institute of Dental Studies including feedback from practicing Endodontists.
How it works:
The Endocator® detects cellular debris by measuring the amount of Adenosine Triphosphate (ATP) and other biomarkers present in the endodontic sample. ATP is present in all living cells and can be used to determine the amount of cellular debris within the canal.
When the sample is added and mixed in the Endocator® Test Swab, the reaction to ATP creates bioluminescence that is detected by the Endocator®. High Endocators means that there are still high levels of debris (e.g. remanent bacteria and/or pulp tissue) in the sample and that additional cleaning is suggested to better debride the canal system.
Ease of use:
Simply rinse the root canal with 1 ml of sterile water and aspirate the water that remains in the canal. Inject the sample into the test swab and activate by fully inserting the swab and shaking. Insert the tester into the Endocator® device, the Endoscore will be displayed in 10 seconds.
With Endocator® now you can achieve:
- Rapid reliable assessment – Utilizes bioluminescence technology to detect residual contamination invisible to microscopes and radiographs, offering an objective, quantitative score of cleanliness
- Increased efficiency – Optimize your disinfection protocol with measurable verification of a thoroughly clean canal
- Improved confidence – Provides visible evidence of canal cleanliness, to reduce the likelihood of retreatments

Frequently Asked Questions
Because this technology is so new there are not any CDT codes for ATP testing. Some of the providers have used code D0415 (microorganism culturing) or D3999 (unspecified endo). It is up to the discretion of the provider to set the fee scale for the test.
Under laboratory conditions the chairside ATP testing can detect the presence of as few as 10 bacteria. In a root canal setting our test can detect ATP well before the presence of a single culturable bacteria. The Endocator® detects ATP from cultural bacteria, unculturable bacteria, nerve tissue, blood, saliva, and apical fluid so it is a much more complete evaluation tool of root canal cleanliness than simple bacterial culturing.
The Endocator® is truly cutting edge technology and research is pending and will be added to the website after publication. Previous attempts to quantify ATP present in root canals was promising but required complicated laboratory techniques, took several minutes to run, and never became popular. Research about success rates of root canals with bacteria, and retreating root canals that are found to have bacteria can be found on pubmed.
One year if placed in the refrigerator and one month at room temperature.
Higher scores 70-100 mean that the root canal has lots of ATP present. This ATP could be from bacteria, nerve, tissue, blood, or saliva. A low scores 0-30 means that the root canal is clean and has low levels of ATP. If you have high levels of ATP it is up to your best clinical judgement as to what do next, but additional rinses, activation, time, and possibly increasing the final file sizes are all possible strategies to bring down ATP levels.
The tooth can be tested anytime to check for ATP levels but at the very least it is a good idea to check for ATP levels just before finishing the root canal or before sealing a tooth with calcium hydroxide in case a second visit is necessary. For research purposes ATP testing is also a great tool to compare various activation methods (sonic vs. Ultrasonic vs laser vs gentlewave).
Blood contamination inside of the root canal will give you high ATP readings. Apical bleeding should be controlled prior to ATP testing.
