Indications for Use
The Sirius Max Diode Curing Light is intended for use as a source of illumination for photo initiated curing and/or activation/ polymerization of dental restorative materials and adhesives.
Device Story
Sirius Max Diode Curing Light is a battery-operated, handheld dental device used by clinicians to polymerize restorative materials and adhesives. It utilizes a solid-state LED module to emit high-intensity light (430-490nm) for curing and a separate white light LED (400-700nm) for intraoral transillumination. The device features a microprocessor-controlled user interface with an OLED display, allowing selection of six curing modes (Normal, Softstart, Pulse, High Power, Xtra Power, Orthodontics) and nine timer settings. The handpiece is constructed of aluminum with a glass lens and is used with disposable barrier sleeves for infection control. The clinician operates the device via a membrane touch pad to trigger light output. By providing controlled radiant energy, the device enables the hardening of dental materials, facilitating restorative procedures. It is recharged via a dedicated station connected to a 5vdc power source.
Clinical Evidence
Bench testing only. Comparative performance testing against the predicate device measured light output across all modes, showing an average variation of 1.4% from settings, well within the ±20% limit per IEC 60601-2-22. Additional testing included depth of cure, conformance to ANSI/ADA Specification No. 48-2, temperature control validation, cleaning/disinfection validation, and software verification/validation.

### Device Description
The Sirius Max Diode Curing Light is shipped as a system consisting of the charging station ("charger"), the handpiece, 50 SiriusMax Barrier Sleeves, an orange protective eye shield, and screwdriver for removal of the battery. The charger allows for placement of the handpiece in a holder with electrical connection for battery charging and interface with the 5vdc power source. The handpiece is constructed of aluminum with plastic control surface and glass output lens and is non-sterile utilizing the barrier sleeves for infection control. The handpiece houses the control circuitry with microprocessor and user interface for selection of mode and curing light output providing visual indications of power settings and of the unit's status. This interface also features the unit's power ON/OFF switch as well as the button to activate the white light intraoral illumination light to aid in the visualization of dental anatomy. The unit is battery operated and contains an internal battery pack with Li batteries. The battery pack is service removable with the use of the screwdriver provide. An instruction for use is also included inside the packaging. The Instructions For Use detail the function of the device and describe the 6 different curing modes. They are Normal mode 1200mw/cm2, Softstart mode 1400mw/cm2, Pulse mode 1400mw/cm2, High Power mode 1300 mw/cm2, Xtra Power mode, 3000mw/cm2, and Orthodontics mode 1400mw/cm2. The curing LED module provides high intensity light in the range of 430-490nm. The white light transillumination LED module (400-700nm) is provided as an aid for illuminating anatomy in the oral cavity.
### Conformity to International Standards
The Sirius Max Diode Curing Light complies with the performance requirements as the predicate device: IEC 60601-1, IEC 60601-2-2, , and IEC 60601-2-22, ANSI/ADA 48-2. The following tests were performed in addition to bench tests described in the 510(k); depth of cure, conformance to ANSI/ADA Specification No. 48-2, Temperature Control Validation, cleaning and disinfection validation, software verification and Validation and IEC 60601-1 Electrical Safety.
### Comparative Performance Data
The Sirius Max Diode Curing Light has been tested side-by-side against the predicate device. Measurements of the subject devices output ranging from 0.1 to 5.0W output all modes were shown to vary from the unit's settings by an average of only 1.4% in all modes. The intended performance of these devices, based on IEC 60601-2-22, is that Curing Light output should vary from the device's setting by less than ± 20% of the setting. Both the subject and predicate devices have been shown to satisfy this standard.

## Comparison of Features and Characteristics
Table 1, following, lists key Features and Characteristics of the subject and predicate devices. Note that the slight change in verbage of Indications for Use is intended to more accurately describe the process of photo-activation of dual cured materials where curing is initiated but not completed by the light activation process. The SiriusMax also has 9 different timer settings for the curing modes compared to 8 found on the predicate device however, output intensities are in the same range and testing was done to validate the depth of cure and confirm substantial equivalence. The SiriusMax has a single Peak wavelength at 460nm whereas the predicate device has a primary peak at 460nm and a small peak at 410nm. The low enerqy of the small peak at 410nm combined with the fact that the vioilet wavelengths have lower penetration depth than blue wavelenghths makes the 460nm the predominant activator and therefore the subject and predicate are substantially equivalent.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
