## Device Story
Ambar APS and Ambar Universal APS are light-curing dental adhesive systems used to bond restorative materials to tooth structure (enamel and dentin). Ambar APS is a 5th generation two-step adhesive; Ambar Universal APS is a 7th generation single-flask system supporting self-etch, selective-etch, and total-etch techniques. Used in dental clinics by professionals for direct restorations, luting of indirect prosthetics, and repairs. The adhesive is applied to the tooth surface and light-cured to facilitate chemical bonding between the tooth and restorative material. Benefits include improved retention and sealing of restorations. The device is supplied in vials.
## Clinical Evidence
Bench testing only. Comparative studies against predicate and reference devices evaluated adhesive strength (MPa), degree of conversion, shear bond strength (ISO 29022), pH, viscosity, water sorption, and water solubility. Results demonstrated subject devices have adhesive strength (38.61/38.02 MPa) and conversion rates (53.8/55.8%) equal to or greater than predicates. Stability studies confirmed 2-3 year shelf life.
## Technological Characteristics
Light-curing dental adhesives. Composition: MDP, methacrylate monomers, photoinitiators, co-initiators, stabilizers, silica filler, ethanol; Ambar Universal APS includes water and surfactant. Sensing/actuation: chemical bonding via light-activated polymerization. Form factor: liquid in vials. Standards: ISO 29022, ISO 10993 (1, 3, 5, 10, 11).
## Regulatory Identification

#### G) Device Description
#### Ambar APS
Ambar APS is a light-curing 5th generation adhesive (two-step adhesive, total etch technique) for bonding restorative materials to dental tissue (enamel and/ or dentin). As the primer and the bonding agent are combined in a single bottle, acid etching is the only previous step needed before applying the adhesive to dentin and enamel.
#### Ambar Universal APS
Ambar Universal APS is a single flask self-etch light-curing adhesive system (Seventh Generation) responsible for the union between tooth structure (enamel and dentin) and restorative materials. The primer and bonding agent are combined in a single flask. Prior use of acid etchant is optional on both tooth 's enamel and dentin, it can be used, therefore, in three ways: self-etch, selective-etch and total-etch.

Discussion: The subject devices are adhesive systems that offer the dental professional a wide range of applications. The Ambar APS and Ambar Universal APS are substantially equivalent to the predicate device (Single Bond 2) and the reference devices (Single Bond Universal and Tetric – N – Bond Universal) above in that all are intended to be used as a 21 CFR 872.3200 resin tooth bonding agent. The subject devices are substantially equivalent to Single Bond 2 in terms of indications. Regarding the claim "Use as metallic or ceramic primer", the Ambar Universal APS it similar to the reference predicate, Single Bond Universal, that indicates the use for "Surface treatment of porcelain, ceramics (including glass ceramics, zirconia and alumina), metal and composite."

## Discussion:
The subject device is similar to the predicate devices in that they are all dental adhesives for promoting union between tooth structure (enamel and dentin) and restorative materials.
Despite differences in results, the subject device demonstrates substantial equivalence to the declared predicates, since all products meet ISO 29022 and the results match

The text includes the company name, address (AV. EDGAR NELSON MEISTER, 474, JOINVILLE, SANTA CATARINA 89219-501 BRAZIL), and phone number (Ph: 55 - 47 - 3441-6131).
the requirements of this International Standard and it does not affect the substantial equivalence.
- Adhesive Strength: The average of the results of the adhesive under analysis is ≥ the average of the internationally renowned brand analyzed in this study.
The bond tensile strength exhibits slightly higher values than shear bond strength. Although there is no minimum tensile bond strength value, 20 MPa or more has been proposed as a reasonable value and a goal to be achieved.
By the results obtained, all the adhesives analyzed presented satisfactory results, with slightly higher values obtained by Dentscare adhesives.
The performance of Ambar APS and Ambar Universal APS satisfactorily met the requirements to support substantial equivalence to the predicate.
- Conversion rate: The average of the results of the adhesive under analysis is > the average of the internationally renowned brand analyzed in this study.
The dental compounds basically consist of a mixture of monomers, filler particles, photoinitiator system, inhibitors and dyes. The monomers have methacrylic groups with the carbon double bond, which are photoactivated, form along several polymer chains. The amount of monomers which are converted into polymers represent the major part of the final product, having a lower volume and a smaller amount of free monomers which can be leachable. An analysis of the volume of data is done by analyzing the amount of duplications that have been disrupted, indicating an expression of polymer chains. The higher the conversation rate values, better the results and efficacy of the final product.
By the results obtained, Ambar APS and Ambar Universal APS have presented the highest values, obtaining a higher efficiency of the final product when compared to the predicate. Thus, the results support substantial equivalence to the predicate.
- Shear bond strength: The average of the results of the adhesive under analysis is ≥ the average of the internationally renowned brands analyzed in this study.
The evaluation of the bonding efficiency between an adhesive and the dentin region is usually analyzed by bond strength between bonded specimens in shear or traction until fracture occurs. There is a wide variability of values (deviation) related to several factors such as water content in the dentin, cleaning of the "Smear Layer", orientation of the dentinal tubules.
The enamel structure has a high content of inorganic material (mineral hydroxyapatite) and low amount of organic material such as collagen, thus presenting a lower water content and facilitating adhesive bonding. However in dentine the amount of organic material is higher and, therefore, the humidity is also higher. As the restorative material is hydrophobic and the dentin is hydrophilic, the adhesive system has to be such that it can match both materials, thus, it must have an amphiphilic characteristic.
In summary, the higher the shear bond values, generally for bonding to the enamel, and bonding by traction, generally for adhesion to the dentin structure, the greater the effectiveness of the adhesive system.

The shear bond strength is one of the indicative of adhesive performance, indicating the shear strength between the tooth / adhesive / restorative interface. In enamel indicates the union effectiveness of an orthodontic cement, for example.
The higher the shear strength or tensile strength values, the greater the effectiveness of the product.
- pH: The pH test is not contemplated in standards for adhesives, however, it is known that 7th generation adhesives must have low hydrogen potential, thus performing the role of acid conditioning.
The average of the results for pH of the adhesive under analysis demonstrate that the subject devices have lower hydrogen potential than the average of the internationally renowned brands analyzed in this study.
- Viscosity: The viscosity property is not contemplated in regulations for adhesives. This aspect does not have impact the in the performance of the product. For this reason, the predicate devices do not refer to viscosity of the product as a quality aspect.
- Water sorption and Water solubility: The results show that the subject devices presented Sorption and Solubility similar to the competing adhesives under analysis. There is no specific standard for sorption and solubility testing on adhesives, so we follow the testing methodology established in ISO 4049 and as an approval criterion we define that the results of our adhesives should be better or statistically equal to competitors of recognized quality on market. ISO 4049 reference values have not been taken into account, assuming that the adhesive class is not covered by this standard.
Conclusion: From the results obtained, the subject devices, Ambar APS and Ambar Universal APS demonstrate equivalent indications for use, shelf life, physical, technical and mechanical properties.
