Date Summary Prepared: September, 24th 2013
#### Device Name:
- Trade Name DIAGNOcam 2170 .
- Common Name Caries detector, laser light, transmission ●
- Classification Name Laser fluorescence caries detection device, per 21 CFR § 872.1745 .
#### Devices for Which Substantial Equivalence is Claimed:
- DIFOTI USB 2.0 SYSTEM (K043068) .
- . Transillumination Cable Ti2200 (K071429)
#### Device Description:
The DIAGNOcam 2170 is a handheld laser fluorescence caries detection device which uses the DIFOTI technology (Digital Imaging Fiberoptic Transillumination) as the functional principle. KaVo DIAGNOcam 2170 delivers images, which are reminiscent of X-rays but which are completely radiation free - by means of a light that is especially adapted to this examination method. The tooth structures allow the passage of light from the entry site to the camera. Areas that block light transmission (e.g. carious lesions) show up clearly as well delimited, dark areas. A digital camera captures the actual situation and makes it visible in real-time on the screen. The USB connector provides electric power to the unit. The DIAGNOcam 2170 will be delivered with a firmware (unit) at the handheld device which is responsible for steering of the camera functions and a computer based software (image) which is responsible to show / display the pictures, store / save the pictures and the possibility of a life stream. The internal laser diode generates an exact wavelength being detectable by the CCD sensor. The DIAGNOcam 2170 follows the international standards for electrical safety and electromagnetic compatibility which are applicable for the use with human beings. The DIAGNOcam 2170 works with a laser wavelength at 788 nm and an output power of 2mW for each laser diode (2 sources). The maximum output power is 21mW/cm2.
{1}------------------------------------------------
The life stream describes a way how the dentist can use the DIAGNOcam 2170. So it is possible to use the DIAGNOcam 2170 to see life images of the teeth and not only to have the possibility to make single pictures. While using the DIAGNOcam 2170 at the teeth the dentist can see real pictures / a video on his monitor.
The tips of the DIAGNOcam 2170 can be sterilized according to the instructions for use. Two tips (small & large) are supplied with the handheld device. Additionally the DIAGNOcam 2170 will be supplied with a holder for the device. This holder allows the dentist to deposit the DIAGNOcam 2170 in a safe position. The holder is intended to be used outside the treatment for general storage.
#### Intended Use of the Device:
The DIAGNOcam 2170 is a diagnostic aid for the detection of open or incipient caries lesions above the gingiva and for monitoring the progress of such lesions.
Indications:
- Detection of smooth surface caries .
- . Detection of occlusal carries
- Detection of proximal caries .
- . Detection of initial caries
- Detection of secondary caries .
- Detection of cracks .
The device is intended for use in a dentist's office or dental clinic.
#### Substantial Equivalence:
The DIAGNOcam 2170 handheld laser fluorescence caries detection device is substantially equivalent to other legally marketed devices in the United States. The DIAGNOcam 2170 functions in a manner similar to and is intended for the same use as the DIFOTI USB 2.0 SYSTEM marketed by Electro-Optical Sciences, inc. and to the Transillumination Cable Ti2200 marketed by Kerr Corporation. The DIAGNOcam 2170 is similar to all three predicate devices in that it is a handheld laser fluorescence caries detection device which uses the transillumination as the functional principle. As the DIFOTI USB 2.0 SYSTEM an internal light source (laser diode) is used to generate the exact wavelength being detectable by the CCD sensor, a USB connection supplies the DIAGNOcam 2170 with power and additional to that the DIFOTI USB 2.0 SYSTEM works with software consisting of a product firmware and a computer based software, which is responsible to show / display the pictures, to store / save the pictures, for the possibility of a life stream and for steering of the camera function.

Sec 4 - 1 -
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.
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.
