No
The description focuses on electrical impedance measurement and calculation, with no mention of AI or ML terms or functionalities.
Yes
The device is used to enlarge the root canal, which is a treatment indication.
Yes
The device description explicitly states that the DP-RCM module "has a root canal measurement capability" and that the device "can be used to measure the length of the canal." Measuring the length of a root canal for treatment planning is a diagnostic function.
No
The device description explicitly states it is composed of hardware modules (DP-RCM module and DP-TR module) and describes physical functions like measuring electrical impedance and acting as a motorized handpiece, indicating it is not software-only.
Based on the provided information, the DENTA PORT is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In vitro diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- DENTA PORT Function: The DENTA PORT directly interacts with the patient's root canal in vivo (within the living body) to measure length and enlarge the canal. It uses electrical impedance measurements within the root canal itself, not on a specimen taken from the body.
Therefore, the DENTA PORT is a medical device used for a dental procedure, but it does not fit the definition of an in vitro diagnostic device.

Device Description
The DENTA PORT is composed of a canal measurement base module (the DP-RCM module) and a canal enlargement module (the DP-TR module).
The DP-RCM module can be used alone and has a root canal measurement capability. It can be used to measure the length of the canal. The root canal length can be measured in a simple and safe way by measuring electrical impedance (400, 8000 Hz) between the electrode (root canal file) located inside of the opened root canal and an oral mucous electrode, calculating the ratio of two impedance values, and thereby indicating the position of the file tip inside the root canal. This allows the dentist to safely and efficiently perform canal enlargements of root canals. The DENTA PORT requires no adjustments or calibrations and can be used whether the canal is dry or filled with strong electrolytes such as blood, hydraulic saline, etc. The size of the file has almost no effect on the measurement. Since the position of the file tip and the meter reading are directly related, root canal enlargement can easily be performed while continuously monitoring the length of the canal electrically. The meter is an easy-to-read liquid crystal display. The position of the file tip is easily determined by the changes in the monitor's audible signals. The unit is powered by commonly available "AA" batteries. Low power consumption enhances long battery life. The file holder and contrary electrode can be autoclaved.
The DP-TR module can be used only when it is connected to the DP-RCM module. When connected, it can be used to enlarge canals while monitoring the position of the file tip inside the canal. It can be used to measure the length of the canal, and it can be used as a low speed motorized handpiece. The DP-TR module connected to the DP-RCM module has the same functions as the DP-RCM module alone, such as root canal measurement, plus it has a dental micromotor and can be used with root canal files. With the accompanying root canal files, the DP-TR enables the mechanical preparation of dental root canals and the removal of gutta-percha points. During the mechanical preparation of the dental root canal, the device measures electrical impedance (400, 8000 Hz) between the file electrode connected to the root canal and an oral mucous electrode by calculating the ratio of two impedance values and indicating the position of the file tip inside the root canal. The device also uses this information for motor movement. This allows the dentist to safely and efficiently perform the mechanical preparation of root canals and the mechanical removal of guttapercha points. The DP-TR module has the following features: Auto Start / Stop, Auto Apical Reverse, Auto Torque Reverse, Two types of motors are available, The position of the file tip is monitored and displayed while the canal is being enlarged, In manual mode, the motor rotates even when the file is outside the root canal. When the files are inside the root canal, the device switches to automatic mode, A foot switch is available. When it is turned on, the motor rotates even when the file is outside the root canal. When the file is inside the root canal, the device switches to automatic mode, Auto slow down is available. When auto slow down is set, the motor rotation speed is reduced automatically when the tip of the file comes near the apex, Files are easy to replace by the push chuck, The volume of the audible signals can be adjusted or turned off, The contra head, file holder, and contrary electrode can be autoclaved as long as the temperature does not exceed 135°C, Only nickel-titanium files can be used with the DP-TR module for mechanical preparation of inside the root canal, A rechargeable battery is used for power supply.

Intended Use
The DENTA PORT is a dental root canal measurement and treatment device that can measure the length of the root canal and enlarge the canal while monitoring the position of the file tip inside the canal.
Technological Characteristics and Substantial Equivalence
The DENTA PORT is composed of a canal measurement base module (the DP-RCM module) and a canal enlargement module (the DP-TR module).
The DP-RCM module can be used alone and has a root canal measurement capability. It can be used to measure the length of the canal.
The DP-TR module can be used only when it is connected to the DP-RCM module. When connected, it can be used to enlarge canals while monitoring the position of the file tip inside the canal. It can be used to measure the length of the canal, and it can be used as a low speed motorized handpiece.
The DP-RCM base module
The root canal length can be measured in a simple and safe way by measuring electrical impedance (400, 8000 Hz) between the electrode (root canal file) located inside of the opened root canal and an oral mucous electrode, calculating the ratio of two impedance values, and thereby indicating the position of the file tip inside the root canal.

The DENTA PORT is substantially equivalent to the Tri Auto ZX (K#970339) because both devices have similar general intended uses, technological characteristics, and operating principles.
The principal differences in the technological characteristics between the DENTA PORT and the Tri Auto ZX are: (1) the DENTA PORT is composed of two modules; (2) the motor of the DENTA PORT has tubing and the Tri Auto ZX does not; (3) the free running speeds are different; (4) the DENTA PORT has two types of motors while the Tri Auto ZX has one; (5) the DENTA PORT has an auto slow down feature; (6) the DENTA PORT uses an LCD while the Tri Auto ZX uses an LED display; and (7) the DENTA PORT has a foot switch.
These differences do not raise any new issues of safety or effectiveness. As such, the DENTA PORT raises no new issues of safety or effectiveness.
