Life Fast Set/ Life Regular Set is a hard-setting Calcium Hydroxide cavity liner and pulp capping agent to be used in conjunction with all permanent restorative techniques.

Device Description

Life Regular Set/Life Fast Set are hard setting Calcium Hydroxide cavity liners and pulp capping agents to be used in conjunction with all permanent restorative techniques. Life is a two-part, base/catalyst- paste/paste system. The two-part system is packaged in tubes. The product is available in two viscosities, Fast Set and Regular Set.

AI/ML Overview

The provided document is a 510(k) premarket notification for a medical device called "Life Regular Set and Life Fast Set," which are calcium hydroxide cavity liners and pulp capping agents. It seeks to demonstrate substantial equivalence to a predicate device, "Life 2 (K012717)."

The document does not include the detailed information requested regarding specific acceptance criteria for device performance (e.g., accuracy metrics, thresholds), a study comparing the device against these criteria, or information on human reader studies, ground truth establishment with experts, or training set details for an AI/CAD system.

Instead, the document focuses on demonstrating substantial equivalence based on:

Similarity in intended use and technological characteristics: The new device has the same intended use and a very similar formulation to the predicate. The primary difference in formulation is a change in the type of fumed silica, which is stated to be insignificant as it does not participate in the reaction.
Manufacturing and packaging changes: The manufacturing location has changed, and the packaging material has been updated. These changes were validated internally.
Non-clinical performance data: Verification and validation activities were performed according to design control requirements (21 CFR 820.30 and ISO 13485:2012) and risk analysis (ISO 14971:2012). The conclusion states these activities demonstrated substantial equivalence and that no new hazards were identified based on post-market data from the internationally sold product.

Therefore, I cannot provide the requested table or detailed information because the provided text does not describe a study that establishes acceptance criteria in terms of quantitative reported device performance for an AI/CAD system, nor does it detail a study proving the device meets distinct performance thresholds. The document's purpose is to demonstrate substantial equivalence to an existing device based on material, manufacturing, and packaging changes, supported by non-clinical validation and risk analysis, rather than a clinical performance study with specific metrics.

If this were an AI/CAD device, the requested information would be crucial. However, for this type of dental material, the FDA's review focuses more on the safety and efficacy of the formulation and manufacturing process, and its equivalence to a device already on the market.

న. Statement of Intended Use:
Life Regular Set/Life Fast Set is a hard-setting Calcium Hydroxide cavity liners and pulp capping agents to be used in conjunction with all permanent restorative techniques.

1. Summary of Technological Characteristics:
  The base formulation of Proposed Life Regular Set and Life Fast Set and the predicate device, Life 2 (K012717), remains unchanged.

The catalyst formulation of Proposed Life Regular Set and Life Fast Set and the predicate device, Life 2 (K012717), is very similar, the only difference being the Fumed Silica. The predicate Life 2 (K012717) contains 2-5% Fumed Silica Aerosil R972, CAS# 68611-44-9. The Proposed Life Regular Set and Life Fast Set contain 2-5% Fumed Silica Cab-o-sil TS720, CAS#67762-90-7.

The mixing of the base and catalyst causes the mixture to harden. This is due to a chelation reaction between the calcium hydroxide and the salicylate moieties. The hardening of the thin layer occurs quickly so that the remaining steps of the procedure can proceed. The intention of a cavity base or pulp liner is to protect the pulp from thermal shock.

The fumed silica is added to serve as a filler and rheological modifier. It does not participate in the reaction. The surface treatment of the fumed silica is conducted to make the filler more hydrophobic and to improve the compatibility with the formulation. The difference between a dimethyldichlorosilane treated fumed silica and a polydimethylsiloxane treated fumed silica is insignificant in this formulation. The formulation utilizing the alternative fumed silica has been on the market for a number of years internationally. Based on post market data, the performance characteristics of this material result in equivalent feedback as that of the predicate. The slight variation in fumed silica does not change the performance characteristics of the device.

The primary tube packaging will be changed from a laminate plastic tube to a polyfoil tube, the same tube in which the international version of the product is currently sold and has been on the market for a number of years. The tube filling operation was validated per an internal process validation. Based on the number of years of successful clinical use of polyfoil tubing internationally and successful validation data, the Proposed Life Regular Set/ Life Fast Set tubing change is deemed substantially equivalent to the predicate Life 2 (K012717).

1. Summary of Non-Clinical Performance Data:
  Verification and validation activities were performed in accordance with design control requirements as specified in 21 CFR 820.30 and ISO 13485:2012 Medical Devices-Quality Management Systems, and the results demonstrated substantial equivalence to the predicate. Risk analysis for the changes in manufacturing, packaging and formulation was performed utilizing ISO 14971:2012, Application of risk management to medical devices. No new hazards were identified based on post market data from the internationally sold product that has been on the market for a number of years utilizing the proposed manufacturing process, packaging and formulation. The filling process was validated per an internal process validation.

8. Substantial Equivalence:

Life 2 (K012717) is an existing device which was granted market clearance by FDA in 2001. Sybron Dental Specialties seeks only to slightly modify the existing device cleared under K012717. Additionally, the device would be produced at a facility in Scafati, Italy.

Table 8.1: Predicate Life 2 (K012717) and Proposed Life Fast Set and Regular Set

Conclusion

The modification of Life Fast Set (PN 16530) to replace the Fumed Silica, the move of manufacturing locations to Scafati, Italy, and the change to the packaging does not affect the intended use of the device nor does it alter the fundamental scientific technology of the device. The nonclinical testing demonstrates that the Proposed Life Regular Set/ Life Fast Set performs as well as the predicate device. Proposed Life Regular Set/Life Fast Set is substantially equivalent to the predicate Life 2 (K012717).
