Steri-Oss' ImProv Temporary Dental Cement serves as a cement for the temporary retention of crown and bridge prostheses. The cement is an anaerobic two part paste which self-cures upon mixing. The product is provided in two syringe-like cylinders made of a polyalkylene material, one containing 10 grams of cement Part A and one containing 10 grams of cement Part B.

AI/ML Overview

The provided text is a 510(k) submission for Steri-Oss' ImProv Temporary Dental Cement. In this type of submission, the manufacturer claims substantial equivalence to previously cleared predicate devices, rather than conducting new performance studies against specific acceptance criteria.

Specifically, the document states: "Performance Data: Not applicable". This means that the submission does not include primary data from a study designed to meet specific acceptance criteria for the device's performance. Instead, substantial equivalence is claimed based on similar technological characteristics (e.g., curing type, system, cement base) to the predicate devices.

Therefore, I cannot provide the requested information for the following points as no such study or acceptance criteria are described in the provided text:

A table of acceptance criteria and the reported device performance
Sample sized used for the test set and the data provenance
Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Adjudication method for the test set
If a multi reader multi case (MRMC) comparative effectiveness study was done, and its effect size
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
The type of ground truth used
The sample size for the training set
How the ground truth for the training set was established
