Dia-Cem is a radiopaque resin cement that can be used in self-cure or light-cure mode. It corresponds to type 2 and 3 of ISO 4049 and contains more than 60% of inorganic filler. Dia-Cem shows high bonding strength on various materials, yet excess material can be easily removed. 3 different shades are available: TR, A2, and A3O.
This document describes the premarket notification (510(k)) for the Dia-Cem dental cement. It focuses on demonstrating substantial equivalence to a predicate device, BisCem, rather than presenting a study proving a device meets specific acceptance criteria in the manner of an AI/ML device.
Therefore, many of the requested categories (2, 3, 4, 5, 6, 7, 8, 9) are not directly applicable as this is a material science characterization for a traditional medical device, not an AI/ML algorithm.
Here's the information extracted that aligns with your request:
1. A table of acceptance criteria and the reported device performance
| Performance Characteristic | Acceptance Criteria (Predicate) | Reported Device Performance (Subject Device - Dia-Cem) |
|---|---|---|
| Working time | A homogeneous and thin film should be formed at 60 sec after the complete of mixing. | A homogeneous and thin film should be formed at 60 sec after the complete of mixing. |
| Flexural strength | More than 50 MPa | More than 50 MPa |
| Film thickness | No greater than 50 µm | No greater than 50 µm |
| Shear bond strength | Equal or greater than 4 MPa | Equal or greater than 4 MPa |
| Biocompatibility | Biocompatible | Biocompatible |
| Shelf-life | 2 years | 2 years |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not applicable in the provided document. The document describes non-clinical performance data based on ISO standards for material properties, not a clinical study with a test set of patient data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not applicable in the provided document. Ground truth, in the context of expert review, is not relevant for this type of material science testing.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable in the provided document.
5. 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 in the provided document. This is not an AI-assisted device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable in the provided document. This is not an AI/ML algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- For the non-clinical performance data: The "ground truth" or reference for the device's performance is established by international standards such as ISO 4049:2019, ISO 29022:2013, ISO 7405:2018, ISO 10993-1:2018, ISO 10993-3:2014, ISO 10993-5:2009, ISO 10993-10:2010, and ISO 10993-11:2017. These standards define the methodologies and acceptable limits for the physical, mechanical, and biocompatibility properties of dental cement.
8. The sample size for the training set
- Not applicable in the provided document. This device does not use an AI/ML algorithm that requires a training set.
9. How the ground truth for the training set was established
- Not applicable in the provided document.
§ 872.3275 Dental cement.
(a)
Zinc oxide-eugenol —(1)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.(2)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 872.9.(b)
Dental cement other than zinc oxide-eugenol —(1)Identification. 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.(2)
Classification. Class II.
