What’s your Endoscore?
The Endocator® is the first and only chairside device that enhances root canal treatment by delivering an adjunctive canal cleanliness score in 10 seconds.* 1,2,3
Endocator® works by detecting trace amounts of adenosine triphosphate (ATP) and other biomarkers inside of a root canal. Low levels of ATP correlate to low levels of cellular debris within the root canal.

Compact and Easy-to-UseThe Endocator® is cordless, compact, and easy-to-use, making it the perfect chairside tool to help assess the cleanliness of your root canal treatments.
Endocator® Features & Benefits
Confirm your root canal is clean in 10 seconds
Know if the root canal is clean
Residual debris is known to contribute to root canal failure. Endocator® is able to detect trace amounts of root canal contamination from bacteria, nerve tissue, blood, saliva, and apical fluid.
Made for root canals
Our patented system for adjunctive root canal testing uses a proprietary equipment and chemistry formulations that have been specifically engineered for endodontic use.
Sensitive & accurate
Research has shown that root canal ATP testing correlates to remanent debris levels present in the root canal. Endocator® detects when root canals are still contaminated with debris and when root canals are clean and ready to be filled.
Easy & fast
Simply rinse the canals with sterile water, then aspirate and inject a sample into the Endocator test swab, activate the tester by pushing down on the top button and get a reading in 10 seconds.

The Science Behind Endocator®
How does Endocator® work?
The Endocator® utilizes bioluminescence technology to detect residual contamination invisible to microscopes and radiographs, offering an objective, quantitative score of cleanliness.
High Endocator® readings 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.

Endocator® Research
Endocator® Studies
- In vitro study using the Endocator® to show the efficacy of sonic activation from the EndoActivator (Nagesh 2025)
- Editorial in Journal of Conservative Dentistry and Endodontics about Endocator® being a paradigm shift in Endodontics (Singh 2024)
- Preprint evaluation of Endocator® to quantitatively evaluate root canal cleanliness (Gambarini 2024)
- Publication correlating Endoscore ATP levels to BMP bacterial Endotoxin levels (Nagesh 2024)
Root canals with bacteria fail more
- Failure rate of root canals that culture positive to bacteria have a five times higher failure rate (32% failed) than teeth that cultured negative to bacteria (6% failed). (https://pubmed.ncbi.nlm.nih.gov/9477818/)
- Failure rate of root canals that require retreatment is three times higher (56% failed) for teeth that culture positive to bacteria compared to teeth that culture negative to bacteria (20% failed). (https://pubmed.ncbi.nlm.nih.gov/17889679/)
Success of ATP and other chairside tests
- An in vivo JOE article in 2015 showed that ATP testing is an effective way of determining when a tooth will culture negative. (https://www.researchgate.net/publication/270826984_Rapid_Method_for_the_Detection_of_Root_Canal_Bacteria_in_Endodontic_Therapy)
- Chairside test showed that teeth that had high levels of bacterial markers had a 4.5 times higher failure rate (80% failed) then teeth that had a low level of bacterial markers (10% failed) (https://pubmed.ncbi.nlm.nih.gov/32635158/)
One visit endo and root fractures
- One Visit Endo- Endocator® can be used to determine when a tooth is clean. Studies have shown that the success rates of one visit root canals are the same as two visit root canals and that the number of bacteria present at the time of obturation is a much more accurate way to predict success (https://pubmed.ncbi.nlm.nih.gov/22892729/)
- Conservative Endodontics- Making a root canal too big can lead to root fractures. An estimated 17% of failed root canals are found to have root fractures. With Endocator® you can be confident that the tooth is clean without having to make excessively large preparations. (https://pubmed.ncbi.nlm.nih.gov/28730236/)

About the Inventor
Randolph Cross DDS
Dr. Randolph Cross graduated Magna Cum with a Molecular Biology and Biochemistry degree and worked in the biotech field before going to dental school then endodontic residency. When completing his root canals Dr. Cross tested various methods to determine when root canals were clean. After looking at several technologies Dr. Cross developed a biomarker formula based on the science of detecting ATP inside of a root canal. Dr. Cross is currently a practicing Endodontist and uses ATP testing on virtually all of his root canals.
