Provides radiopaque luting for restorative procedures. Benefits include secure fixation of dental prosthetics and caries restoration in unstressed areas.

Clinical Evidence

Bench testing only. Compliance with ISO 9917-1:2007 for physical/chemical properties (setting time, film thickness, compressive strength, acid erosion, lead content, radio-opacity) and ISO 10993 for biocompatibility (cytotoxicity, sensitization, irritation, systemic toxicity, subchronic toxicity, genotoxicity).

Technological Characteristics

Powder/liquid system; powder: silica, alumina, strontium fluoride; liquid: polycarboxylic acid, distilled water. Acid-base reaction principle. Radiopaque. Non-sterile. Shelf life 2 years. Complies with ISO 9917-1:2007.

Indications for Use

Indicated for dental patients requiring cementation of metal-based or high-strength ceramic restorations (inlays, onlays, crowns, bridges, posts, screws) or orthodontic bands, and restoration of caries in unstressed areas (Luting II only).

Regulatory Classification

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. 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.

#### 9. Summary of Biocompatibility

The new device, Glass Ionomer Cement (Luting), is substantially equivalent to the predicate devices (K980695) that have been on the market for decades and with no clinical adverse events. The formulation of new device does not contain any new or non-conventional chemicals compared to the legally marketed predicate device.

We selected our Glass Ionomer Cement ( Filling II, shade: A3) as the representative model in biocompatibility tests and those biocompatibility test reports can be used in the biological evaluation of Glass Ionomer Cement (Luting). The main reason is that Glass Ionomer Cement (Luting) has the same chemical compositions of glass powder, raw material suppliers, function mechanism and manufacture process as Glass Ionomer Cement ( Filling II, shade: A3).

Biocompatibility tests were performed to satisfied the ISO 10993 standards. The test items include Cytotoxicity, Sensitization, Irritation, Systemic Toxicity, Subchronic Toxicity and Genotoxicity.

## 10. Summary of Substantial Equivalence

As with the comparison shown in substantial equivalence discussion, these two devices are similar in almost all aspects. In addition, the new device adds indications for use compared to the predicate device, the minor differences in indications for use fall within the intended use of the predicate device and do not impact safety and effectiveness proved by the tests. The details of physical properties are slightly different, but these two devices are in equivalent to other legally marketed devices of this type. Regarding the shelf life, the performance of the new device is not adversely affected by aging in 3.5 years. In order to ensure the quality of products, we have choose 2 years as the shelf life for Glass Ionomer Cement (Luting).

It can be seen that the minor differences between the new device and the predicate device are not of significance and do not raise questions of safety and effectiveness as compared to the predicate device. SHANDONG HUGE DENTAL MATERIAL CORPORATION concludes that Glass Ionomer Cement (Luting) is substantially equivalent to the predicate device described herein.
