No
The description focuses on the physical properties, manufacturing process, and sterilization of the dental files. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML. The submission is primarily for a change in sterilization status and labeling.
No
The device is used to file, shape, and remove tissue from root canals, which are procedures for treating a disease rather than therapeutically treating the ailment itself.
No
Explanation: The device is described as being used to file and shape root canals and remove necrotic tissue, which are therapeutic and procedural actions, not diagnostic ones.
No
The device description clearly describes physical instruments made of stainless steel with plastic handles and silicone stops, used for shaping root canals. It is a hardware device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "file and shape root canals and to remove necrotic tissue." This is a direct intervention on the patient's anatomy, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details a physical instrument used for mechanical manipulation within the root canal. It doesn't mention any reagents, assays, or analysis of biological samples.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing information for diagnosis, monitoring, or screening
This device is clearly a surgical/dental instrument used for a therapeutic procedure within the root canal.
N/A
Intended Use / Indications for Use
Used to file and shape root canals and to remove necrotic tissue as a means to create a funnel-shaped cavity.

Device Description
FlexoFile® files and instruments are manufactured for DENTSPLY Caulk by DENTSPLY Maillefer®. They are pre-1976 medical devices and are exempt from premarket notification. However, this 510(k) submission is necessary because DENTSPLY Caulk plans to market these devices as Sterile and to revise the labeling to reflect this change. There are no changes to the composition, manufacturing process, or sterilization process.
STERILE FLEXOFILE® FILES AND INSTRUMENTS are precision instruments twisted from a single shaft of stainless steel for maximum fracture resistance. They feature preinserted silicone stops for convenience and safety. They reduce the chance of apical transportation and breakage from binding in the canal. They feature non-slip plastic handles for a firmer grip, as well as ISO color coding for easy identification.
After stenlization, these files and instruments presented the same resistance in torsion and shear stress as non-sterilized instruments. No significant change in color or mechanical behavior of the plastic handles was evident following gamma irradiation.

INTENDED USE: STERILE FLEXOFILE® FILES AND INSTRUMENTS are used to file and shape root canals and to remove necrotic tissue as a means to create a funnel-shaped cavity.
TECHNOLOGICAL CHARACTERISTICS: As noted above, there are no changes in the composition, manufacturing or sterilization of these files and instruments.
These files and instruments were subjected to sterilization by gamma irradiation from a Cobalt 60 source. The validation method used was AAMI Method 1.
The device package is a compartmentalized container with six (6) individually separated cells. The package includes a heat-sealed non-tearing perforated thermal adhesive strip. This strip allows for a single cell to be opened per file as required by the dentist, while all other file cells remain sealed and sterile.
We believe that the fact that the new device is identical to the predicate device, along with the sterilization data presented, supports the safety and effectiveness of STERILE FLEXOFILE® FILES AND INSTRUMENTS for the intended uses.
