It is supplied in a cartridge and applied to the gingival sulcus using a manual dispensing gun. The clinician applies the paste into the sulcus, leaves it in place for 1 to 2 minutes, and then removes it using an air/water spray with simultaneous aspiration. This process creates a dry, retracted sulcus, facilitating dental procedures such as impressions and restorations. The device is intended for use by dental professionals in a clinical setting. ## Clinical Evidence No clinical data provided; substantial equivalence is based on technological and intended use similarities to legally marketed predicate devices. ## Technological Characteristics Paste formulation containing aluminum chloride; delivered via cartridge and manual dispensing gun; non-electronic, mechanical application. ## Predicate Devices - Stav-put Impregnated (Coltene/Whaledent) - Ultrapak E (Ultradent Products, Inc.) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
