Indications for Use
DeltaFil (in capsule) is used for geriative filling procedures. The procedures. The product is designed for use in final restorations of Class I, II, III, and V of deciduous teeth and as a long - term restorative in non-load bearing areas of Class I and II carious lesions. It is also used as a restorative and sandwich material for heavy stress in Class I and II cavities. DeltaFil can also be used as a core build-up material. DeltaFil Conditioner: - Treatment of the smear layer · Conditioning of the cavity
Device Story
DeltaFil is a radiopaque glass ionomer restorative material supplied in disposable capsules; used with a compatible 10% aqueous polyacrylic acid conditioner. The conditioner is applied to the prepared tooth surface to remove the smear layer and condition the cavity, improving the adhesive bond between tooth tissue and the restorative cement. The restorative material is a two-part powder/liquid glass polyalkenoate cement mixed in a standard dental capsule dispenser. Used in dental offices/clinics by dental professionals for permanent or temporary restorations. The device provides a restorative filling or core build-up, benefiting patients by restoring tooth structure and function in carious lesions or cavities. The healthcare provider applies the conditioner, then the mixed cement, to the prepared cavity.
Clinical Evidence
Bench testing only. Performance data confirmed compliance with ISO 9917-1:2007 for water-based cements, including compressive strength (≥ 180 MPa), radiopacity (200 %Al), acid erosion (≤ 0.1 mm), and acid-soluble lead content (≤ 100 ppm). Shear bond strength on dentin (4.9 ± 1.3 MPa) and enamel (13.6 ± 2.4 MPa) was evaluated. Biocompatibility was assessed per ISO 10993.
Technological Characteristics
Two-part powder/liquid glass polyalkenoate restorative cement (ISO 9917-1:2007) and 10% aqueous polyacrylic acid conditioner. Supplied in disposable 'Applicap' capsules for use with a mechanical capsule dispenser. Radiopaque. Non-sterile. No software or electrical components.
Indications for Use
Indicated for geriatric and pediatric restorative filling procedures, including final restorations of Class I, II, III, and V of deciduous teeth, long-term restoration of non-load bearing Class I and II carious lesions, heavy stress Class I and II cavities (as restorative/sandwich material), and core build-ups.
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.

* Predicate SBS data for GC Fuji IX GP with and without the compatible GC Cavity Conditioner
## Non-clinical Performance Testing
Performance data demonstrated that DeltaFil (in capsule) and DeltaFil Conditioner meet all predetermined acceptance criteria contained in the product specification and are suitable for their intended use. The risks associated with the use of the new devices were found acceptable when evaluated in accordance with ISO 14971. Risks and benefits associated with the proposed and the predicate device are the same. Design verification and validation activities consisted of physical testing, biocompatibility evaluation, and stability (shelf life) validation.
## Comparison of Technological Characteristics with the Predicate Devices
The general material type, intended use, and performance specifications of DeltaFil (in capsule) and DeltaFil Conditioner are substantially equivalent to the predicate devices, GC Fuji IX GP and 3M Espe Ketac Conditioner. DeltaFil (in capsule) and GC Fuji IX GP are two-part powder-liquid glass ionomer polyalkenoate restorative dental cement as defined in ISO 9917-1:2007 Dentistry - Water-Based Cements – Part 1: powder/liquid acid-base cements. Both DeltaFil (in capsule) and GC Fuji IX GP are supplied in capsules that are briefly mixed by the user in a standard dental capsule mixer prior to dispensing.
DeltaFil Conditioner and 3M Espe Ketac Conditioner are both mild, blue-tinted aqueous solutions of polyacrylic acid intended to enhance the bond between the glass ionomer restorative cement and the tooth surface by treating the smear layer to condition the cavity. DeltaFil Conditioner is intended for use prior to the application of DeltaFil (in capsule). The Diadent DiaEtch cleared in K192273 is cited

as a reference device to confirm biological safety for methlylene blue pigment used to enhance the visibility of dental cavity pretreatments.
## Conclusion
The DMG Chemisch-Pharmazeutische Fabrik GmbH DeltaFil (in capsule) and DeltaFil Conditioner meet all pre-determined acceptance criteria of the testing performed to confirm substantial equivalence to the predicate devices.
