The Compex HD is intended to be used by a dentist or health care provider to warm and dispense dental composite materials contained in a compule or PLT (Pre Loaded Tip) to 155 degrees F (68 degrees C).
The Compex HD uses a heating device to elevate the temperature of dental composite material contained in a compule (PLT) to allow it to flow and be easily extruded. It utilizes a plastic housing in the shape of a traditional dispensing qun. The housing contains a heater element(s) and/or an electrically conductive plastic compule that itself acts as a heater when a current is applied. A control circuit board assembly and rechargeable lithium lon battery are used to apply power to the heater. A separate wall plug-in USB power supply is used to charge the battery. The unit will not function with the USB power supply connected to the unit.
The provided text describes the Compex HD device, a composite warmer for dental materials, and compares it to a predicate device, the Calset. It focuses on non-clinical performance data to demonstrate substantial equivalence, rather than a detailed AI algorithm performance study. Therefore, some of the requested information, particularly related to AI-specific metrics like human reader improvement with AI assistance, MRMC studies, or training set details, is not applicable to this device.
Here's a breakdown of the available information based on your request:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Heats dental composite materials to approximately 155°F (68°C). | The Compex HD heats the composite to an approximate temperature of 155°F (68°C). |
| Dispenses dental composite materials from a compule or PLT. | The Compex HD is designed to warm and dispense dental composite materials contained in a compule or PLT. |
| Compliance with general safety and essential performance standards. | Successfully passed ANSI/AAMI/IEC 60601-1 (general requirements for basic safety and essential performance) and ANSI/AAMI/IEC 60601-1-2 (electromagnetic disturbances). |
| Compliance with specific temperature accuracy for composite warming. | Both the Compex HD and the predicate Calset heat the composite to a temperature of approximately 155°F (68°C). |
| Material flow improvement after heating. | The heated composite exhibits improved flow and is dispensed more easily. |
| Elimination of additional temperature settings for anesthetic carpules/whitening bleach. | The Compex HD is not designed to warm anesthetic solutions or whitening bleach and does not have the 98°F (37°C) or 130°F (54°C) temperature settings found in the predicate. The physical design is incompatible with these materials. |
| Ease and safety of dispensing. | The process of dispensing composite is similar to the predicate, requiring fewer steps and less time with the Compex HD. The unit is considered as safe and effective as the predicate. |
2. Sample Size Used for the Test Set and Data Provenance
The document refers to a "test set" in the context of comparing the Compex HD and Calset devices.
- Sample Size: The number of compules/PLTs tested is not explicitly stated. It mentions "testing was performed on both devices using thermocouples inserted into composite filled compules."
- Data Provenance: The tests were conducted internally by the manufacturer, AdDent, Inc. The data is retrospective, as it's part of the 510(k) submission. No country of origin for the data is specified beyond the company's location in Danbury, Connecticut, USA.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
- Not Applicable. This device is a warming and dispensing tool, not an AI diagnostic or decision support system that requires expert interpretation for ground truth. The performance evaluation relies on physical measurements (temperature, flow, safety standards compliance) rather than expert consensus on diagnostic accuracy.
4. Adjudication Method for the Test Set
- Not Applicable. As the performance evaluation involves objective physical measurements and adherence to engineering standards, there is no need for an adjudication method typically used for subjective diagnostic interpretations.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
- Not Applicable. This device is not an AI-powered system, and no MRMC study or assessment of human reader improvement with AI assistance was conducted or is relevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Not Applicable. This device does not involve an algorithm for standalone performance evaluation in the context of AI. Its performance is evaluated mechanically and thermally.
7. The Type of Ground Truth Used
- The "ground truth" for the performance evaluation primarily consists of:
- Direct Physical Measurements: Thermocouple readings to verify the composite temperature reached 155°F (68°C).
- Engineering Standards Compliance: Successful adherence to international safety and EMC standards (ANSI/AAMI/IEC 60601-1 and ANSI/AAMI/IEC 60601-1-2).
- Qualitative Assessment: Observation of improved flow of heated composite and ease of dispensing.
8. The Sample Size for the Training Set
- Not Applicable. This device is not an AI/machine learning device, so there is no "training set" in the conventional sense.
9. How the Ground Truth for the Training Set Was Established
- Not Applicable. As there is no training set for an AI algorithm, no ground truth was established for it.

Description of the Device:
Background: The traditional method of dispensing dental composite contained in a PLT (Pre-Loaded Tip) or compule is to use a mechanical composite dispensing device. The compule is loaded into the tip of the dispenser and hand applied mechanical force is used to extrude the material to the prepared dental cavity. Dispensing these materials at room temperature can be difficult due to their viscous nature. The Compex HD heats the composite material contained in the compule prior to use. The heated composite exhibits improved flow and is dispensed more easily. Composite materials are used to repair or restore teeth in the general population, but are not an integrated part of this device. In addition, research shows that pre-heating composite prior to light curing also improves depth of cure, shortens time of cure along with many other improved physical properties.
General Description: The Compex HD uses a heating device to elevate the temperature of dental composite material contained in a compule (PLT) to allow it to flow and be easily extruded. It utilizes a plastic housing in the shape of a traditional dispensing qun. The housing contains a heater element(s) and/or an electrically conductive plastic compule that itself acts as a heater when a current is applied. A control circuit board assembly and rechargeable lithium lon battery are used to apply power to the heater. A separate wall plug-in USB power supply is used to charge the battery. The unit will not function with the USB power supply connected to the unit.

- With the table top Calset predicate device, the compule containing the composite material (PLT) is loaded in a standard handheld composite dispenser which is then inserted into a pre-heated tray (holster) that sits on top of the Calset heater base. Once the compule reaches the desired application temperature of 155°F (68°C) in approximately three minutes, the dispenser with loaded compule is removed from the heated tray (holster) and the heated composite material is dispensed to the patient.
{5}------------------------------------------------
With the Compex HD unit, the heater is integrated into the front of the dispenser. This is in the form of a heating element, or alternatively the compule itself is made from electrically conductive plastic and acts a heating element. The compule (PLT) containing the composite material is loaded in the front of the unit. The heater is activated by a push button switch on the control panel. Once the unit reaches operating temperature of approximately 155°F (68°C), a LED light changes color to indicate that the material is ready to be dispensed directly to the patient. See figure 1.

Technical Characteristics of the Compex HD compared to the Predicate Device:
Discussion: The Compex HD unit performs the same function as the predicate Calset device - to warm composite materials to 155°F (68°C) prior to dispensing the material used to repair the patient's teeth. In both applications the heated composite becomes less viscous and flows more easily, and therefore is dispensed more easily with less physical effort and more control. The Calset must be used with a separate mechanical dispenser such as the CoMax (product code KXR Applicator, Resin, Exempt), also made by AdDent, Inc. The Compex HD dispenses material directly. In one version of the Compex HD the compule containing composite is warmed by being in close proximity to one or more PTC (Positive Temperature Coefficient) electrical heating elements. In another version of the Compex HD the compule itself is molded from electrically conductive plastic that itself becomes a heater when a current is applied to the compule. Unlike the Calset, the Compex HD is not designed to warm or dispense anesthetic solution or whitening bleach, and as a result does not require the other two temperature settings of 98°F (37°C), and 130°F (54°C).
{7}------------------------------------------------
Non-Clinical performance data: To demonstrate that the Compex HD and Calset predicate device are substantially equivalent, testing was performed on both devices using thermocouples inserted into composite filled compules to determine the temperature of the composite during heating. The test results demonstrate that both devices heat the composite to a temperature of approximately 155°F (68°C). Refer to Appendix B Product Tests, Test Report # 131 and Test Report # 165 for test results.
In addition, both the Calset predicate unit and the Compex HD have been tested and successfully passed the following international standards (refer to Appendix C Product Safety and EMC Test Reports:
- . American National Standard/International Standard ANSI/AAMI/IEC 60601-1, "Medical Electrical Equipment - Part 1: General Requirements for Basic Safety and Essential Performance (Third Edition, Amendment 1 2012)."
- . American National Standard/International Standard ANSI/AAMI/IEC 60601-1-2. "Medical Electrical Equipment, Part 1-2: General Requirements for Basic Safety and Essential Performance – Collateral Standard: Electromagnetic Disturbances - Requirements and Tests, 4th Ed. (2014)."
Clinical performance data: Not Applicable.
Performance data summary: The non-clinical test results demonstrate that the Compex HD and predicate Calset essentially perform the same function – to heat dental composite material contained in a compule (PLT) to approximately 155°F (68°C).
In addition, the process of dispensing the composite material is similar in that the Calset is used with a separate handheld dispenser to hold the compule while it is being heated and then dispensed while the Compex HD has this feature incorporated into a single device.
Since there is no difference in the temperature of the applied composite material and the process of dispensing the composite is similar, requiring fewer steps and less time with the Compex HD, the unit is as safe and effective as the predicate Calset device,
Elimination of the additional temperature settings of 98°F (37°C), and 130°F (54°C) as featured on the predicate Calset device presents no additional safety hazard. The Compex HD unit is not intended to heat anesthetic carpules or whitening bleach and the physical design of the Compex HD is incompatible with these materials. Use of the 130°F (54°C) temperature setting with composite materials is no longer common.
In addition the safety of the Compex HD is demonstrated by successfully passing the required safety and EMC standards referenced above in Non-clinical performance data.
