This outhego in setyantator stermization and Instilling of contax morent ADA recommendations for water quality having a maximum of 200 cfu/ml.
The DentaPure® DP90 and DP365 Cartridges are in-line assemblies incorporating iodinated resin and a polypropylene filter. The cartridge is connected to the municipal water supply at the air/water service junction box in each operatory. It consists of a polypropylene in-line filter with the inner chamber filled with an iodinated ion exchange resin that imparts 2-6 ppm of iodine into the water as it flows through. The filter portion is of a sufficiently small porosity to retain water-born particulate, and would thereby reduce the amount of particulate that would reach the patient from the dental water system. The iodine that is released reduces biofilm and the chance of cross contamination by introducing the germicide, iodine, into the water system downstream of the filter. The DentaPure® Cartridge is a disposable unit, retrofittable to all modern dental operatory units.

The letter from the FDA confirms substantial equivalence to a predicate device and approval for marketing, but it does not detail performance testing or acceptance criteria.
Therefore, I cannot fulfill the request to provide:
- A table of acceptance criteria and reported device performance
- Sample size used for the test set and data provenance
- Number of experts and qualifications for ground truth establishment
- Adjudication method
- MRMC comparative effectiveness study details (effect size)
- Standalone performance study details
- Type of ground truth used
- Sample size for the training set
- How ground truth for the training set was established
The document focuses on the regulatory aspects (510(k) summary, FDA clearance letter) and general claims about the device's function and adherence to ADA guidelines (reducing bacteria levels to less than 100 cfu/ml, which is below the ADA recommendation of 200 cfu/ml). It mentions a prior equivalent device (DentaPure® DP1, K963548), suggesting that the substantial equivalence was likely based on comparison to the performance of that device, but no specific study details are given in this text.

The DentaPure® DP40 Cartridge is for use on dental unit water lines attached to the dynamic dental instruments, i.e., high-speed handpiece, three-way air/water syringe and ultrasonic scaler. This cartridge in conjunction with currently recommended practices regarding sterilization and flushing of dental instruments reduces bacteria from the water supplied through the instruments to a level that will meet or exceed the current ADA recommendations for water quality having a maximum of 200 cfu/ml.
The DentaPure® DP40 Cartridge is an in-line assembly incorporating iodinated resin and a polyolefin filter. The cartridge is connected to the pickup tube of a bottle water system. It consists of a polyolefin in-line filter with the inner chamber filled with an iodinated ion exchange resin that imparts 2-6 ppm of iodine into the water as it flows through. The filter portion is of a sufficiently small porosity to retain water-born particulate, and would thereby reduce the amount of particulate that would reach the patient from the dental water system. The iodine that is released reduces biofilm and the chance of cross contamination by introducing the germicide, iodine, into the water system downstream of the filter. The DentaPure® Cartridge is a disposable unit, retrofittable to all modern dental operatory units with independent bottle water systems. The cartridge is installed in the bottle reservoir tubing with quick connect fittings for ease of change.
The provided document is a 510(k) summary for the DentaPure® DP40 Cartridge, a dental unit waterline purification cartridge, and a letter from the FDA regarding its substantial equivalence. It does not contain a study with detailed acceptance criteria and reported device performance in the format requested. The document describes the device's intended use and general performance claims but lacks the specific data points often found in a scientific study report.
However, based on the information provided, I can infer some elements as they relate to the device's performance claims.
Here's a breakdown of what can be extracted and what is missing:
Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Reduce bacteria levels in dental unit water lines to less than 200 cfu/ml (ADA recommendation). | Commonly reduce bacteria levels to less than 100 cfu/ml. |
Missing Information Based on Request:
The document is a premarket notification for a medical device and describes its intended use and general performance claims. It is not a detailed study report, therefore much of the requested information about a specific study's methodology, sample sizes, expert involvement, and ground truth establishment is not present.
- Sample size used for the test set and the data provenance: Not specified.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not specified.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not specified.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is not an AI-assisted diagnostic tool; it's a water purification cartridge.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This device is not an algorithm.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc.): The "ground truth" for the performance claim relies on microbial colony-forming unit (cfu/ml) counts, which is an objective laboratory measure of bacterial concentration in water samples.
- The sample size for the training set: Not applicable. This device is not an AI/machine learning model that requires a "training set."
- How the ground truth for the training set was established: Not applicable.
Summary of Device Performance Claims from the Document:
The DentaPure® DP40 Cartridge is designed to be connected to the pickup tube of a bottle water system in dental operatories. It incorporates an iodinated resin and a polyolefin filter. As water flows through, the resin imparts 2-6 ppm of iodine, which is stated to reduce biofilm and the chance of cross-contamination by acting as a germicide. The filter portion retains water-borne particulate.
The key performance claim states: "When used in conjunction with these normal practices, the DentaPure® DP40 Cartridges commonly reduce bacteria levels to less than 100 cfu/ml." This performance is presented as exceeding the current ADA recommendation of having less than 200 cfu/ml in dental unit water lines.
The document is a regulatory submission demonstrating substantial equivalence to a predicate device (DentaPure® DP1, K963548), not a detailed scientific report on a specific study. Therefore, it focuses on asserting that the device meets safety and efficacy claims rather than providing extensive experimental data in the format of a clinical trial.

Here's an analysis based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance:
| Acceptance Criteria (ADA Recommendation) | Reported Device Performance (DentaPure™ Cartridge) |
|---|---|
| Less than 200 cfu/ml | Less than 1 cfu/ml (commonly reduces) |
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size:
- Test 1 (Iodine Residual): Specific sample size not mentioned, but it refers to "samples of the first 5 ml" taken over "43 days."
- Test 2 (Dental Office Conditions): Specific sample size not mentioned, but it refers to "Tests" performed in "a dental office."
- Data Provenance:
- Test 1: Performed internally (likely by the manufacturer or a laboratory contracted by them) to show "efficacy of the DentaPure™ Cartridge and its substantial equivalence to the Clearline™ filter."
- Test 2: "performed in a dental office, under actual conditions." This suggests prospective, real-world data collection.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
- The document does not specify the number of experts or their qualifications for establishing the ground truth. The "ground truth" here is the bacterial count, which is likely determined by standard microbiological laboratory methods by technicians. There's no mention of clinical expert judgment involved in establishing the bacterial count.
4. Adjudication Method for the Test Set:
- The document does not describe an adjudication method. Bacterial counts are typically objective measurements, not subject to adjudication in the same way as, for example, image interpretation.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- No, a multi-reader multi-case (MRMC) comparative effectiveness study was not performed. The device is a filter, not a diagnostic aid requiring human interpretation.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study:
- Yes, the performance described is standalone. The device (filter) itself is being tested to reduce bacterial counts; there is no "human-in-the-loop" interaction with the device in terms of its core function, only in its installation and regular maintenance.
7. Type of Ground Truth Used:
- Bacteriological counts (Colony Forming Units - cfu/ml): This is a direct, objective measurement of the presence and quantity of viable bacteria.
8. Sample Size for the Training Set:
- The document does not mention a "training set" in the context of device development or performance. This is a physical device, and its efficacy is tested rather than "trained" like a machine learning algorithm.
9. How the Ground Truth for the Training Set Was Established:
- Not applicable, as there is no mention of a training set for this physical device.
