Indications for Use
Self-curing glass ionomer based radiopaque filling cement, for dental use only. (1) Restoration of primary teeth. (2) Restorations of Class III, V and limited Class I cavities. (3) Base linings under composite and amalgam. (4) Core build-up.
Device Story
Glass Ionomer Cement (Filling) is a powder-liquid dental restorative material. It consists of silica, alumina, and strontium fluoride powder mixed with poly carboxylic acid liquid. The device operates via an acid-base reaction to form a radiopaque cement. It is used by dental professionals in a clinical setting to restore primary teeth, fill Class III, V, and limited Class I cavities, provide base linings under composite or amalgam, and perform core build-ups. The clinician manually mixes the powder and liquid, applies the cement to the tooth structure, and allows it to self-cure. The resulting restoration provides a permanent or temporary filling, benefiting the patient by restoring tooth function and structure.
Clinical Evidence
Bench testing only. Physical and chemical properties were evaluated against ISO 9917-1:2007, including net setting time (1.5-6 min), compressive strength (≥100 MPa), acid erosion (≤0.17 mm), acid-soluble lead content (≤100 mg/kg), and radio-opacity. Biocompatibility testing was performed per ISO 10993 standards, including cytotoxicity, sensitization, irritation, systemic toxicity, subchronic toxicity, and genotoxicity.
Technological Characteristics
Powder/liquid system. Powder: Silica, Alumina, Strontium Fluoride. Liquid: Poly Carboxylic Acid, Distilled Water. Principle: Acid-base reaction. Standards: ISO 9917-1:2007 (water-based cements), ISO 7405:2008, ISO 10993 series (biocompatibility). Form factor: Manual mixing kit (powder bottle, liquid bottle, spatula, mixing pad).
Indications for Use
Indicated for dental patients requiring restoration of primary teeth, Class III, V, and limited Class I cavities, base linings under composite/amalgam, or core build-up. Contraindicated for pulp capping.
Regulatory Classification
Identification
Zinc oxide-eugenol is a device composed of zinc oxide-eugenol intended to serve as a temporary tooth filling or as a base cement to affix a temporary tooth filling, to affix dental devices such as crowns or bridges, or to be applied to a tooth to protect the tooth pulp. Dental cement other than zinc oxide-eugenol is a device composed of various materials other than zinc oxide-eugenol intended to serve as a temporary tooth filling or as a base cement to affix a temporary tooth filling, to affix dental devices such as crowns or bridges, or to be applied to a tooth to protect the tooth pulp.

### Summary of Biocompatibility
The new device. Glass Ionomer Cement (Filling), is substantially equivalent to the predicate devices that have been on the market for decades and with no clinical adverse events. The formulation of new device does not contain any new or non-conventional chemicals compared to the legally marketed predicate device.
We selected our Glass Ionomer Cement (Filling II, shade: A3) as the representative model in biocompatibility tests because it is the worst case scenario. In the meantime, the two types of our Glass Ionomer Cement (Filling) has the same chemical compositions, indications for use, function mechanism and manufacturing process.
Biocompatibility tests were performed to satisfy the ISO 10993 standards. The test items include Cytotoxicity, Sensitization, Irritation, Systemic Toxicity, Subchronic Toxicity and Genotoxicity.
### Summary of Substantial Equivalence
As with the comparison shown in substantial equivalence discussion, these devices are same or similar in almost all aspects. The new device adds an indication for use compared to the primary predicate device (Base linings under composite and amalgam) which fall within the indication for use of the reference predicate device (K101869, "Base/liner"). The details of physical properties are slightly different, but these devices are in equivalent to other legally marketed devices of this type.
It can be seen that the minor differences between the new device and the predicate device are not of significance. Shandong Huge Dental Material Corporation concludes that Glass Jonomer Cement (Filling) is substantially equivalent to the predicate device.

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

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
