Hydro-Cast Versa-Temp Eugenol-Free Provisional Cement is used for temporarily cementing crowns and bridges. Hydro-Cast Versa-Temp provides for easy seating of the temporary, very fast first stage cure with an excellent consistency that allows the removal of excess material from the work area and undercuts, and a rigid set combined with easy removal of the temporary.
The device is a syringe dispensing system that dispenses a eugenol free temporary dental cement
Acceptance Criteria and Study for Hydro-Cast Versa-Temp Non-Eugenol Provisional Cement
This document describes the acceptance criteria and the non-clinical performance testing conducted to demonstrate the substantial equivalence of the Hydro-Cast Versa-Temp Non-Eugenol Provisional Cement.
1. Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Initial Set: 90 sec +/- 30 sec (60-120 seconds) | Min: 80 sec, Max: 91 sec |
| Final Set: 3 min +/- 30 sec (150-210 seconds) | Min: 175 sec, Max: 196 sec |
2. Sample Size and Data Provenance for Test Set
- Sample Size: 10 random subgroups of three samples each, totaling 30 samples.
- Data Provenance: The data was generated through internal non-clinical performance testing conducted by Kay-See Dental. The location of the testing is not explicitly stated beyond "Kay-See Dental performed test." It's a retrospective study of the device's characteristics.
3. Number of Experts and Qualifications for Ground Truth
Not applicable. This study focuses on the physical properties of a dental cement, specifically its setting times. The ground truth for setting times is established by predefined physical characteristics (rubbery consistency for initial set, hardened material for final set) observed during the testing, not by expert consensus or interpretation of images.
4. Adjudication Method for Test Set
Not applicable. As described above, the ground truth for setting times is determined by direct observation of physical changes in the material, not through expert adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
Not applicable. This is a non-clinical performance test for a dental cement, not a study involving human readers or AI assistance.
6. Standalone (Algorithm Only) Performance
Not applicable. This is a non-clinical performance test for a dental cement, not an algorithm-based device.
7. Type of Ground Truth Used
The ground truth used was based on objective physical observations during the testing process:
- Initial Set: Defined as reaching a "rubbery consistency."
- Final Set: Defined as becoming "hardened material."
8. Sample Size for the Training Set
Not applicable. This document describes a non-clinical performance test to confirm specifications of a physical product. There is no mention of a "training set" in the context of this type of testing.
9. How the Ground Truth for the Training Set Was Established
Not applicable. As there is no training set for this type of non-clinical testing, the establishment of its ground truth is irrelevant.

Discussion NON-CLINICAL PERFORMANCE TESTING AND DATA
The critical performance characteristics of Hydro-Cast Versa-Temp Non-Eugenol Provisional Cement are Initial Set and Final set. Kay-See Dental performed test to assure the product performed to specification.
Specifications:
Initial Set - 90 sec +/- 30 sec
Final Set - 3 min +/- 30 sec
Test procedure:
Conditions - 75% humidity, 85 degree F
Sampling - 10 random subgroups of three samples each
The catalyst and base components were dispensed and mixed to obtain a .5 gram sample. Using an electronic stop watch, the samples were monitored for initial set ( rubbery consistency) and then for final set (hardened material).
| Test results: | Initial Set | Final Set |
|---|---|---|
| Min | 80 sec | 175 sec |
| Max | 91 sec | 196 sec |
Conclusion:
The results of this testing provides additional assurance that Hydro-Cast Versa-Temp Non-Eugenol Provisional Cement does provide the important two stage cure and its performance is substantially equivalent to the predicate device.
