No
The device description and performance studies focus on the chemical composition and dissolving properties of a solvent, with no mention of AI or ML.
No
The device is a solvent used to dissolve root canal sealers during retreatment, not to treat a disease or condition itself.
No
The device is a solvent used to soften root canal sealers during retreatment, which is a therapeutic function, not a diagnostic one.
No
The device description clearly states the device is a solvent composed of chemical substances (ethyl acetate, amyl acetate, and thymol), indicating it is a chemical product, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "Root canal sealers solvent when canal retreatment is required." This describes a product used within the body (in the root canal) to dissolve materials.
- Device Description: The description confirms it's a solvent used for endodontic cements in the context of endodontic retreatment. It acts directly on materials within the tooth.
- Lack of IVD Characteristics: An IVD is a medical device used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. This device does not perform any such tests on biological samples.
Therefore, ENDOSOLV is a therapeutic device used in a dental procedure, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Two studies were performed in accordance to ISO 6876:2012 by Septodont in order to compare the effectiveness of ENDOSOLV (new device, K172839/S001) in comparison with ENDOSOLV E (predicate device, K980633) and ENDOSOLV R, considered positive control. The literature review revealed the effectiveness of those solvents in their intended indication: soften respectively eugenate-based and phenolic resin based root canal sealer when an endodontic retreatment is necessary. Purified water is then used as negative control in both assays. Moreover, a sealer was also used as negative control: Acroseal, it is an epoxy-resin based root canal sealer and neither of the solvents is indicated to soften this material. The first assay permits to conclude that ENDOSOL V (new device, K172839/S001) is as effective as ENDOSOLV E (predicate device, K980633) to dissolve eugenate based root canal sealer. Because of the successful results obtained with the new formulation that were comparable to ENDOSOLV E (predicate device, K980633), the intended performance of dissolving eugenate based root canal filling material is confirmed.
Moreover, the second study permits to demonstrate the performance of ENDOSOLV (new device. K172839/S001) to dissolve resin based root canal filling material. This study showed ENDOSOLV (new device, K172839/S001) results comparable to those obtained with ENDOSOLV R (only approved for sale in EU; indication: soften phenolic resin based root canal sealer; voluntary withdrawal of device from EU and Canada for precautionary reasons in order to avoid any risk of exposure of formamide to pregnant patients), confirming the intended performance of ENDOSOLV (new device, K172839/S001) to dissolve resin based root canal filling material.

IV. Device Description
ENDOSOLV (new device, K172839/S001) is a solvent used for eugenate-type or phenolic resin-based endodontic cements in the context of endodontic retreatment. This solvent is able to soften conventional zinc oxide eugenol cements and phenolic resin type

sealers in the context of endodontic retreatment. It is indicated for use as a root canal sealer solvent when canal retreatment is required.
Despite being highly successful, some endodontic treatments do not respond to initial therapy for different reasons and, hence, retreatment, also called canalar desobturation, becomes necessary. Many techniques are available for endodontic retreatment including the use of a solvent.
ENDOSOLV (new device, K172839/S001) composition consists of ethyl acetate, amyl acetate and thymol. Ethyl acetate and amyl acetate are the two main components of the formulation that are effective in dissolving zinc oxide-eugenol-based and resin based filling material.
V. Indication for Use
ENDOSOLV (new device. K172839/S001): Root canal sealers solvent when canal retreatment is required.
ENDOSOLV E (predicate device, K980633): Root canal filling remover for zinc-oxide eugenol-based materials.
The Indication for Use statement for ENDOSOLV (new device. K172839/S001) is not identical to the predicate devices; however, the differences do not alter the intended therapeutic use nor do they affect the safety and effectiveness of the device in comparison to the predicate device.
ENDOSOLV (new device. K172839/S001) in comparison to ENDOSOLV E (predicate device. K980633) does not limit the intended use of the root canal filling remover to zincoxide eugenol based material. ENDOSOLV (new device. K172839/S001) widens the intended use scope of the product to 'root canal sealers solvent when canal retreatment is required. This new indication for use includes both the conventional zinc oxide eugenol cement and resin type sealers in context of endodontic retreatment.
VI Comparison of Technological Characteristics with the Predicate Device
Ethyl acetate and amyl acetate are the two main components of the formulation in ENDOSOLV (new device, K172839/S001) that are effective in dissolving zinc oxideeugenol-based and resin based filling materials.
The predicative devices ENDOSOLV E (reference device, K780003) and ENDOSOLV E (predicate device, K980633) the only difference between the two devices was the removal of solvent, trichloroethane replaced by tetrachloroethylene in ENDOSOLV E (predicate device, K980633). The formula was changed because trichloroethane is banned in France.
Next, the ENDOSOLV (new device, K172839/S001) in relation to ENDOSOLV E (predicate device, K980633) the major difference is the ingredient tetrachloroethylene
005_510(k) Summary Page 2 of 4

which has been replaced by Ethyl Acetate. The reason for the change is Tetrachloroethylene is due to concerns of toxicity. In addition, overall formulation quantities has been modified minimally between the predicate devices and new device. ENDOSOLV (new device, K172839/S001) has been adjusted to account for the substitutional change in solvent from tetrachloroethylene to Ethyl Acetate.

Performance Testing
Two studies were performed in accordance to ISO 6876:2012 by Septodont in order to compare the effectiveness of ENDOSOLV (new device, K172839/S001) in comparison with ENDOSOLV E (predicate device, K980633) and ENDOSOLV R, considered positive control. The literature review revealed the effectiveness of those solvents in their intended indication: soften respectively eugenate-based and phenolic resin based root canal sealer when an endodontic retreatment is necessary (Gambrel et al., 2005;Canakci et al., 2015;Ramzi et al., 2010;Saglam et al., 2013). Purified water is then used as negative control in both assays. Moreover, a sealer was also used as negative control: Acroseal, it is an epoxy-resin based root canal sealer and neither of the solvents is indicated to soften this material. The first assay permits to conclude that ENDOSOL V (new device, K172839/S001) is as effective as ENDOSOLV E (predicate device, K980633) to dissolve eugenate based root canal sealer. Because of the successful results obtained with the new formulation that were comparable to ENDOSOLV E (predicate device, K980633), the intended performance of dissolving eugenate based root canal filling material is confirmed. Please see Table 1 for Summary of Results.
Moreover, the second study permits to demonstrate the performance of ENDOSOLV (new device. K172839/S001) to dissolve resin based root canal filling material. This study showed ENDOSOLV (new device, K172839/S001) results comparable to those

Substantial Equivalence
ENDOSOLV (new device, K172839/S001) in relation to ENDOSOLV E (predicate device, K980633) the major difference is the ingredient tetrachloroethylene which has been replaced by Ethyl Acetate. The reason for the change is Tetrachloroethylene has concerns of toxicity. In addition, overall formulation quantities has been modified minimally between the predicate device and new device. This is due to ENDOSOL V (new device, K172839/S001) has been adjusted to account for the substitutional change in solvent from tetrachloroethylene to Ethyl Acetate.
