Device Story
RnD TE and RnD SE are aqueous primers applied to tooth surfaces (dentin) by dental professionals during restorative procedures. The device functions by rewetting the tooth surface to reach optimal moisture levels and desensitizing the area, while also inhibiting matrix metalloproteinases (MMPs) to prevent long-term bond degradation. The material is a single-component, non-sterile liquid supplied in a kit with applicators. It is applied in a single coat with a 5-second dwell time. By ensuring proper surface conditions and inhibiting degradation, the device aids dental adhesives in achieving their full potential, reducing post-operative sensitivity, and improving bond integrity. It is intended for use in a clinical dental setting.

### 6) Description of Subiect Device:
RnD TE and RnD SE is an aqueous primer used to rewet and desensitize a tooth prior to bonding. Bonding to tooth structure presents many challenges including the determination of the proper conditions for starting the bonding protocol. The tooth can be left too wet or too dry which could lead to debonding or post-operative sensitivity. RnD TE and R&D SE have been designed to aid in reaching the appropriate moisture level to provide an initial surface that allows an adhesive to reach its full potential.
The subject device formulations also work to ensure the long term bond integrity by limiting the development of matrix metalloproteinases (MMP's) that have been cited as a contributor to bond degradation over time.
RnD TE and RnD SE will be sold as a kit contain a 3ml bottle of RnD along with a single cavity well and Mircobrush® applicators. RnD has been designed as a single use material and is non-sterile. The material is a single component material that is applied directly to the tooth with no other components added prior to use.
### 7) Indications for Use:
- 1) Rewetting tooth surface prior to bonding
- 2) Desensitizing
- 3) Preventing bond degradation
The indications for use for the proposed device are smiliar to the indications for use for the predicate devices: HEMA-GLU (K951220) and Hemaseal & Cide (K990779). Aqua Prep F (K961822) does not specifically address any impacts on bond degradation but is consistent in stressing rewetting and desensitizing. The indications for use are similar for two of the three predicate devices, and thus the
materials are substantially equivalent in terms of intended use.
A comparison table of the indications for use is shown below:

Shear bond testing was completed utilizing the Notched Edge Shear Bond Strength test (*) method.
#### 10) Discussion of Substantial Equivalence:
The subject device has the same intended use and technical characteristics as the named predicate devices. The indications for use for the proposed device are similar to the indications for use for the predicate devices: HEMA-GLU (K951220) and Hemaseal & Cide (K990779). Aqua Prep F (K961822) does not specifically mention any impacts on bond degradation in its indications for use, but is consistent with the subject device in including rewetting and desensitizing. The final predicate device which does not contemplate bond degradation is still used in a consistent manner with similar uses. All of the components utilized within the RnD formulations are industry standard materials used in similar materials which have the same indications for use.
Differences are also noted between the subject and predicate devices. The subject device demonstrates higher bond strength to dentin than its primary predicate, and a slightly decreased film thickness. While the material composition of the subject device features all components observed in the primary predicate, the subject device also featured NaF as part of its formulation, unlike the primary predicate. Reference devices are included to address these differences noted between the subject and primary predicate devices.
The specifications that are important to determine substantial equivalency of a dental adhesive system are bond strengths associated to enamel and dentin (tooth structure). The bond strengths as noted in above table compare the primary predicate device HEMA GLU (K951220) to the subject device. In both enamel and dentin bonding, the results were equivalent.
### 11) Clinical and Non-clinical Performance Data:
No clinical testing was required to support the applicant device as the indications for use and components are equivalent to the predicate devices along with other legally marketed products.
{8}------------------------------------------------
These types of products have been utilized within the Dental Industry for more than 20 years with no reported adverse effects. The non-clinical testing of the proposed device included ISO 29022:2013 - Dentistry - notched edge shear bond strength test. The method includes substrate selection, storage and handling of tooth structure, as well as the procedure for testing. Nonclinical test data supports the stated equivalence of the subject and predicate devices.
#### 12) Conclusion:
The subject device has the same intended use and technical characteristics as the named predicate devices. Device comparisons presented above illustrates this with a direct comparison of the devices in terms of intended use, components, and function. As such, the subject device may be considered substantially equivalent to the predicate devices.

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.
