Device Story

RnD TE and RnD SE are aqueous primers applied to tooth surfaces (dentin) by dental professionals during restorative procedures. The device functions by rewetting the tooth surface to reach optimal moisture levels and desensitizing the area, while also inhibiting matrix metalloproteinases (MMPs) to prevent long-term bond degradation. The material is a single-component, non-sterile liquid supplied in a kit with applicators. It is applied in a single coat with a 5-second dwell time. By ensuring proper surface conditions and inhibiting degradation, the device aids dental adhesives in achieving their full potential, reducing post-operative sensitivity, and improving bond integrity. It is intended for use in a clinical dental setting.

Clinical Evidence

No clinical data. Bench testing only. Performance supported by ISO 29022:2013 notched edge shear bond strength testing comparing subject device to predicates. Results showed equivalent bond strengths to enamel and dentin.

Technological Characteristics

Aqueous primer containing glutaraldehyde, methacrylate monomer (HEMA), and sodium fluoride. Single-component, non-sterile liquid. Applied as a single coat with 5-second dwell time. Film thickness: 4 microns. pH: Neutral. Tested per ISO 29022:2013.

Indications for Use

Indicated for desensitizing, rewetting, and preventing bond degradation of tooth surfaces prior to bonding.

Regulatory Classification

Identification

Bonding to tooth structure presents many challenges including the determination of the proper conditions for starting the bonding protocol. The tooth can be left too wet or too dry which could lead to debonding or post-operative sensitivity. RnD TE and R&D SE have been designed to aid in reaching the appropriate moisture level to provide an initial surface that allows an adhesive to reach its full potential. The subject device formulations also work to ensure the long term bond integrity by limiting the development of matrix metalloproteinases (MMP's) that have been cited as a contributor to bond degradation over time. RnD TE and RnD SE will be sold as a kit contain a 3ml bottle of RnD along with a single cavity well and Mircobrush® applicators. RnD has been designed as a single use material and is non-sterile. The material is a single component material that is applied directly to the tooth with no other components added prior to use. ### 7) Indications for Use: - 1) Rewetting tooth surface prior to bonding - 2) Desensitizing - 3) Preventing bond degradation The indications for use for the proposed device are smiliar to the indications for use for the predicate devices: HEMA-GLU (K951220) and Hemaseal & Cide (K990779). Aqua Prep F (K961822) does not specifically address any impacts on bond degradation but is consistent in stressing rewetting and desensitizing. The indications for use are similar for two of the three predicate devices, and thus the materials are substantially equivalent in terms of intended use. A comparison table of the indications for use is shown below: | Device | Subject Device K161077 RnD TE and RnD SE | Primary Predicate K951220 HEMA GLU | Reference K961822 Aqua Prep | Reference K990779 Hemaseal & Cide Desenstizer | |-------------------------------------|------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Indications for Use Statement | 1) Rewetting tooth surface prior to bonding 2) Desensitizing 3) Preventing bond degradation | 1) superior desensitizing agent, to be placed under dental cements or other restorative materials - temporary, provisional or final. 2) can be used for desensitization of amalgam restorations, either conventional or bonded. 3) helps kill bacteria, 4) alter nerve responses 5) aids bonding primers in penetrating etched dentin. | 1) Rewetting dentin and enamel following etching and drying of the dental cavity preparation 2) Rewetting dried hydrophilic dental tissues following dental procedures 3) Rewetting etched and dried enamel prior to Pit & Fissure Sealant treatment 4) Desensitizing | 1) Elimination of post- op sensitivity - precluding the need to do remakes 2) Superior disinfection of preparations 3) Enhancement and prolongation of bond strength 4) Reduction of microleakage | 510K Submission for RnD K161077 Apex Dental Materials, 330 Telser Road Lake Zurich, IL 60047 CONFIDENTIAL {5}------------------------------------------------ #### Technological Characteristics: 8) All components of RnD formulations are found in legally marketed predicate devices and are industry standard materials used in rewetting and desensitizing materials for more than 20 years.

The indications for use for the proposed device are similar to the indications for use for the predicate devices: HEMA-GLU (K951220) and Hemaseal & Cide (K990779). Aqua Prep F (K961822) does not specifically mention any impacts on bond degradation in its indications for use, but is consistent with the subject device in including rewetting and desensitizing. The final predicate device which does not contemplate bond degradation is still used in a consistent manner with similar uses. All of the components utilized within the RnD formulations are industry standard materials used in similar materials which have the same indications for use. Differences are also noted between the subject and predicate devices. The subject device demonstrates higher bond strength to dentin than its primary predicate, and a slightly decreased film thickness. While the material composition of the subject device features all components observed in the primary predicate, the subject device also featured NaF as part of its formulation, unlike the primary predicate. Reference devices are included to address these differences noted between the subject and primary predicate devices. The specifications that are important to determine substantial equivalency of a dental adhesive system are bond strengths associated to enamel and dentin (tooth structure). The bond strengths as noted in above table compare the primary predicate device HEMA GLU (K951220) to the subject device. In both enamel and dentin bonding, the results were equivalent. ### 11) Clinical and Non-clinical Performance Data: No clinical testing was required to support the applicant device as the indications for use and components are equivalent to the predicate devices along with other legally marketed products. {8}------------------------------------------------ These types of products have been utilized within the Dental Industry for more than 20 years with no reported adverse effects. The non-clinical testing of the proposed device included ISO 29022:2013 - Dentistry - notched edge shear bond strength test. The method includes substrate selection, storage and handling of tooth structure, as well as the procedure for testing. Nonclinical test data supports the stated equivalence of the subject and predicate devices. #### 12) Conclusion: The subject device has the same intended use and technical characteristics as the named predicate devices. Device comparisons presented above illustrates this with a direct comparison of the devices in terms of intended use, components, and function. As such, the subject device may be considered substantially equivalent to the predicate devices.
