The LOOP™ is a source of illumination for curing photo-activated dental restorative materials and adhesives.
LOOP™ is a high-performance LED (Light Emitting Diode) light source for polymerization of dental materials used by trained dental professionals. It is suitable for use with a broad range of light-cured dental materials including materials for restoratives such as light-cured and dual-cure cements, composites, bonding agents/adhesives, bases, liners, fissure sealants, temporaries, as well as luting materials for brackets and indirect restorations such as ceramic inlays. LOOP™ consists of a wireless handpiece and a charging base with an integrated calibration station. The device is a medical electrical device in accordance with IEC 60601-1-2. LOOP™ features a patented coaxial feedback sensing system that measures the actual irradiance, which is the light power striking the targeted tooth. The feedback data allows LOOPTM to make corrective adjustments to the LED power output hundreds of times per second. This continual corrected "closed loop" operation ensures that the targeted surface of the restorative dental material receives the intended irradiance independent of operator-induced distance variations.
This document is a 510(k) premarket notification for a dental device, the LOOP™ LED Curing Light System. It does not contain the detailed information necessary to fully answer your request regarding acceptance criteria and study proving the device meets those criteria, specifically concerning AI/ML capabilities, human expert adjudication, or large-scale clinical performance studies.
The provided text primarily focuses on demonstrating substantial equivalence to a predicate device based on technical specifications, intended use, and general safety and performance testing. It does not describe an AI/ML-driven device or studies that would typically involve acceptance criteria related to algorithmic performance metrics (e.g., sensitivity, specificity, AUC), human reader studies, or expert ground truth establishment for such a device.
Here's why the document doesn't provide the requested information:
- Device Type: The LOOP™ LED Curing Light System is a physical dental curing light. It is described as having a "patented coaxial feedback sensing system that measures the actual irradiance" and makes "corrective adjustments to the LED power output." This describes a control system, not an AI/ML algorithm that makes diagnoses, predictions, or image interpretations.
- Performance Data: The "Performance Data" section lists various engineering, electrical safety, biocompatibility, and software verification/validation tests. These are standard tests for medical devices, particularly electronic hardware. It explicitly states, "No animal or clinical studies were conducted." This confirms that no clinical performance study, particularly one involving human readers or comparative effectiveness, was performed or submitted.
- Lack of AI/ML Specifics: There is no mention of algorithms, machine learning models, training data, test data, ground truth establishment by experts, or any of the typical components of an AI/ML device submission. The "Software Verification and Validation Testing" section refers to software as a "moderate" level of concern due to potential minor injury from failure, which is standard for embedded software in medical devices, not for AI/ML functionality.
Therefore, I cannot populate the requested table or answer the specific questions about AI/ML study design, expert involvement, and performance metrics because this information is not present in the provided document.
The document describes a different type of device and a different type of substantial equivalence demonstration. If you are looking for information on AI/ML device approvals, this specific document does not provide such details.
