White Mfg., Ltd. - **Product Code:** [EBF](/submissions/DE/subpart-d%E2%80%94prosthetic-devices/EBF.md) - **Decision Date:** Jan 9, 1997 - **Decision:** SESE - **Submission Type:** Traditional - **Regulation:** 21 CFR 872.3690 - **Device Class:** Class 2 - **Review Panel:** Dental ## Indications for Use These materials are intended for use in preparation of tooth material prior to restoration by etching of the surface. ## Device Story Super-Dent Etching Gel and Micro-Etch Gel are phosphoric acid-based gels used in dental clinics. Applied by dentists to tooth surfaces via syringe and hollow applicator to etch enamel/dentin prior to restoration. Gel formulation provides visibility and viscosity to prevent migration to sensitive oral tissues. Increased viscosity improves adhesion compared to predicate. Washed away with water after etching process. Enhances bonding surface for restorative materials. ## Clinical Evidence No clinical data. ## Technological Characteristics Aqueous gel containing nominal 40% ortho-phosphoric acid. Colored for visibility. High viscosity for localized placement. Delivered via syringe and hollow applicator. Manual application. ## Regulatory Identification Tooth shade resin material is a device composed of materials such as bisphenol-A glycidyl methacrylate (Bis-GMA) intended to restore carious lesions or structural defects in teeth. ## Predicate Devices - Zenith 40% Phosphoric Acid Gel ([K890464](/device/K890464.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Both devices are coloured for visibility in contrast with tooth material. They are sufficiently viscous to remain where placed and avoid potentially harmful contamination of more sensitive oral tissues. Both devices wash readily from the site when etching is complete. The subject device is intentionally more viscous than the predicate device to improve adhesion after placement. {2} PAGE 20 OF 33 # PREMARKET NOTIFICATION 510(k) SUMMARY (continued) ## NON-CLINICAL DATA: Non-clinical testing includes tests for pH, acid content, adhesion and water washability. The tests indicate results for pH and acid content which are comparable within formulation and experimental accuracy. The test for adhesion indicates better adhesion of the subject device. The device is intentionally more viscous than the predicate device to improve adhesion after placement. The test for water washability indicates marginally easier washability for the predicate device. This is a direct result of the intentionally increased viscosity (and adhesion) of the subject device. The washability of the subject device is satisfactory on consideration of the method of removal. ## CLINICAL DATA: There is none applicable ## CONCLUSIONS: The data summarised above indicates that the subject device is substantially equivalent to the predicate device. Any differences in performance are a result of improvements designed to render the product safer and more effective in clinical use. --- **Source:** [https://fda.innolitics.com/submissions/DE/subpart-d%E2%80%94prosthetic-devices/EBF/K964179](https://fda.innolitics.com/submissions/DE/subpart-d%E2%80%94prosthetic-devices/EBF/K964179) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
