The "Intended Use / Indications for Use" states that the device is "for use by dental professionals as an aid in the diagnosis and monitoring of dental caries."
No
The device description explicitly details hardware components such as electrodes, a meter, a battery, an LCD display, timer circuits, and a beeper, indicating it is a physical instrument, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are performed outside of the living body.
- Device Function: The Electronic Caries Detector works by applying an electrical current directly to the tooth within the patient's mouth. It measures the electrical properties of the tooth structure in situ.
- Sample Type: The device does not analyze a sample taken from the body. It interacts directly with the anatomical site (teeth) in the living patient.
Therefore, while it is a diagnostic device used in a clinical setting, it does not meet the definition of an In Vitro Diagnostic.

Device Description
The ECD is a portable instrument that provides an electrical current source, a meter with a digital read-out between 00 and 100, and indicator and reference electrodes to aid in the detection and monitoring of non-cavitated and cavitated caries lesions in teeth.
The ECD indicator electrode is comprised of a replaceable, single-use, stainless steel probe tip. This component is sized and dimensionally configured to achieve close contact with the tooth being examined. The tip ensures electrical contact with dentinal fluid at sites that are not readily accessible or evaluated using traditional means. The ECD indicator electrode is paired with a reference electrode to complete the necessary electrical circuit. The reference electrode is a stainless steel lip hook that rests on the patient's lower lip.
The device is powered by a 9 volt alkaline battery, regulated down to 5 volts. The unit has a 2 ½ digit LCD display, two timer circuits, and a beeper. The first timing circuit is triggered upon circuit completion. The beeper sounds for 3 seconds, the probe is then removed, and the second timer holds the display for 5 seconds. Then the display returns to zero, ready for the next measurement.

PREDICATE DEVICE IDENTIFICATION
The Electronic Caries Detector is substantially equivalent to the following predicates:
| 510(k)
Number | Predicate Device Name / Manufacturer | Primary
Predicate |
|------------------|--------------------------------------------------|----------------------|
| K090598 | CarieScan Pro - Cariescan LLC | ✓ |
| K982105 | Oral Potential Meter - Pertec of Wisconsin, Inc. | |
SUMMARY OF NON-CLINICAL AND CLINICAL TESTING
No FDA performance standards have been established for Electronic Caries Detector. The following tests were performed to demonstrate substantial equivalence, based on current industry standards:
- . Biocompatibility (per ISO 10993)
- . In vitro performance testing on extracted teeth
- In vivo performance testing on teeth before and after extraction
The results of these tests indicate that the Electronic Caries Detector is substantially equivalent to the predicate devices.
EQUIVALENCE TO PREDICATE DEVICES
Ortek believes that the Electronic Caries Detector is substantially equivalent to the predicate devices based on the information summarized here:
The subject device has similar design, technological characteristics, and uses similar or identical materials as the devices cleared in K090598 and K982105. The subject device has identical indications for use as the device cleared in K090598 and identical intended use as the devices

510(k) Summary
cleared in K090598 and K982105. The ECD uses electrical conductance similar to the device cleared in K982105. The power source of the subject device differs compared to both predicates, however, it uses a lower voltage battery (9V) than the primary predicate (110V). Performance testing of the subject device is similar to the performance of the primary predicate, however, the ECD used a comparison to biopsy whereas the primary predicate compared to visual-tactile scores of the evaluated teeth. Ortek believes that biopsy is considered the current gold standard and the performance scores are more significant compared to visual-tactile readings.
CONCLUSION
The Electronic Caries Detector is considered substantially equivalent to the predicate devices based on the testing performed, the identical indications for use, and similar technological characteristics. Based on the testing performed, including biocompatibility, performance and clinical testing, it can be concluded that the subject device does not raise new issues of safety or efficacy compared to the predicate devices.
