MTA FILLAPEX
MTA-Fillapex is a root canal sealer intended for the permanent scaling of root canals and may be used in combination with root canal obturation materials.
MTA Fillapex is a mineral trioxide aggregate (MTA) and resin toot canal sealer used during endodontic treatment to permanently fill the canal system following debridement and disinfection. It consists of two component pastes that are combined in a dual barrel syringe for ease of dispensing and consistent dosage. Being hydrophilic in nature, MTA-FILLAPEX is desirable as a root filling material because an isolated dry field is not necessary for use. Moisture does not negatively affect the sealing ability and is required for proper setting. It is used in combination with gutta-percha or silver points during root canal obturation.
The provided text describes the 510(k) submission for MTA Fillapex, a root canal sealer. It details performance criteria and tests conducted to demonstrate substantial equivalence to predicate devices, especially a modified version of K113568 with the addition of titanium dioxide to the base paste. However, this document does not describe a study, or acceptance criteria, for a device that uses AI. Instead, it's for a dental material (root canal sealer). Therefore, many of the requested fields related to AI/algorithm performance are not applicable.
Here's an analysis based on the provided text, focusing on the material it does describe:

Biocompatibility | Biocompatible | Biocompatible (based on prior K113568 testing) | 1, 2 |
Shelf Life | 2 years | 2 years | 1, 2 |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not explicitly state the sample sizes used for each test beyond numerical results (e.g., "33.38 mm" for flow). The data provenance is also not specified in terms of country of origin or whether it was retrospective or prospective. The tests were performed as "Design Verification Tests" in response to a "Failure Modes and Effects Analysis (FMEA)" related to a modification (addition of titanium dioxide).
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. This is for a dental material, not an AI/software device requiring expert ground truth for classification or diagnosis. Performance metrics are based on physical and chemical properties and industry standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This is for a dental material; there is no adjudication process involving multiple human readers for performance metrics like flow or setting time.
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. This is for a dental material, not an AI device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is for a dental material, not an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the physical and chemical properties (flow, setting time, solubility, radiopacity, etc.), the "ground truth" is established by adherence to industry standards (specifically ISO 6876:2012) and established laboratory testing protocols. For biocompatibility, reliance is placed on previous testing for the predicate device (K113568) and the chemical composition.
8. The sample size for the training set
Not applicable. This is for a dental material, not an AI model requiring a training set.
9. How the ground truth for the training set was established
Not applicable. This is for a dental material, not an AI model.

The device is provided non-sterile.
This document describes the Angelus Indústria de Produtos Odontológicos S/A MTA Fillapex, a root canal sealer. The submission is a 510(k) premarket notification (K113568) and focuses on demonstrating substantial equivalence to previously marketed devices.
Here's an analysis of the provided information regarding acceptance criteria and the supporting study:

Important Note: The provided document states that "Performance testing that conformed to the protocols and recommended values described in ISO 6876 Dental root canal sealing materials was performed." However, it does not explicitly list the specific acceptance values (e.g., "flow > X mm") for each parameter from ISO 6876, nor does it provide the exact numerical results for MTA Fillapex for each test. It simply states that "Test reports included [list of tests]."
2. Sample Size Used for the Test Set and the Data Provenance
This submission is a 510(k) for a medical device and relies on non-clinical performance testing and biocompatibility data, not a clinical study with a "test set" of patient data.
- Sample Size for Non-Clinical Testing: The document does not specify the exact number of samples (e.g., number of specimens for flow testing) used for each non-clinical test. It broadly states that "side-by-side cytotoxicity testing" and "performance testing" were performed.
- Data Provenance: The testing was performed by or for the manufacturer, Angelus Indústria de Produtos Odontológicos S/A, based in Brazil. The data is thus considered internal manufacturer data from controlled laboratory settings. It is not retrospective or prospective patient data from a clinical setting.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable. This submission does not involve human expert interpretation of clinical data or images to establish a "ground truth." The "ground truth" for non-clinical performance tests is determined by the standardized methods and measurements defined in ISO 6876.
4. Adjudication Method for the Test Set
Not applicable. There is no "test set" in the context of clinical data requiring expert adjudication. The non-clinical tests follow direct measurement and evaluation against pre-defined ISO standards.
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. This is a traditional medical device (root canal sealer), not an AI/Software as a Medical Device (SaMD). Therefore, no MRMC study, AI assistance, or effect size related to human reader improvement is relevant or discussed.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. This is a physical medical device, not an algorithm or AI.
7. The Type of Ground Truth Used
For the non-clinical performance tests (flow, working time, setting time, etc.), the "ground truth" is defined by the protocols and recommended values described in the international standard ISO 6876 Dental root canal sealing materials. For biocompatibility, the ground truth is established by the methods outlined in ISO 10993-5 Biological evaluation of medical devices – Part 5: Tests for in vitro cytotoxicity.
8. The Sample Size for the Training Set
Not applicable. There is no concept of a "training set" for physical medical devices of this type. Performance is demonstrated through direct testing against established material science standards.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no "training set."
